  • Predictive Maintenance and IoT Sensors on Ageing Production Lines

    Beyond Preventative Maintenance

    Preventative maintenance, servicing equipment on a fixed schedule regardless of its actual condition, has long been the standard approach to avoiding unplanned breakdowns in FMCG manufacturing. Predictive maintenance takes this further, using sensor data and condition monitoring to identify developing faults before they cause a failure, allowing maintenance to be scheduled based on actual equipment condition rather than a generic time interval. For manufacturers running ageing production lines, where original equipment may be well past its designed service life but remains too costly to replace wholesale, predictive maintenance and the low cost sensor technology now available to support it represent a genuinely practical opportunity to reduce unplanned downtime.

    Why Ageing Equipment Benefits Most

    Predictive maintenance delivers the greatest value where failure risk is least predictable, and this is precisely the situation on ageing production equipment. A new machine, still within its original design life and maintained to specification, tends to fail in relatively predictable ways, making scheduled preventative maintenance reasonably effective. Equipment that has been in service for fifteen or twenty years, however, behaves less predictably. Bearings wear unevenly, motors draw increasing current as insulation degrades, and mechanical components develop faults that a fixed maintenance schedule was never designed to anticipate.

    For manufacturers who cannot justify the capital cost of wholesale equipment replacement, and who are instead managing a mixed fleet of ageing and newer equipment, predictive maintenance offers a way to extend the useful life of older assets more safely, by giving genuine visibility into their actual condition rather than relying on generic maintenance intervals that may be too conservative in some cases and insufficient in others.

    What IoT Sensor Technology Actually Involves

    The technology underpinning modern predictive maintenance has become significantly more accessible in recent years. Low cost vibration sensors can be retrofitted to motors, pumps, and gearboxes to detect the early signs of bearing wear or misalignment, well before a fault becomes audible or produces a measurable temperature increase. Current sensors monitoring motor draw can flag developing electrical faults or increasing mechanical load. Temperature sensors on bearings, drives, and electrical cabinets provide early warning of overheating that often precedes failure.

    Critically, this sensor data does not need to feed into an expensive, bespoke monitoring platform to be useful. Many modern industrial sensors can integrate directly with existing PLC infrastructure, feeding condition data into the same Allen Bradley or Siemens control systems already managing the production line, with alarms and trend data made visible through existing HMI screens rather than requiring an entirely separate monitoring system.

    Retrofitting Sensors to Existing Control Systems

    For manufacturers with existing Allen Bradley or Siemens PLC infrastructure, retrofitting condition monitoring sensors is often a more incremental and cost effective step than it initially appears. Rather than replacing an entire control system, sensors can frequently be integrated into spare input capacity on an existing PLC, or connected via a small additional input module, with new logic added to log trend data and raise alarms based on defined thresholds. This approach allows manufacturers to add predictive maintenance capability progressively, starting with the highest risk or highest consequence equipment, such as refrigeration compressors or critical line drive motors, rather than requiring a large upfront investment across the entire facility.

    Building the Business Case

    The business case for predictive maintenance rests on comparing the cost of sensor installation and monitoring against the cost of the unplanned downtime it prevents. For a critical piece of equipment, such as a refrigeration compressor supporting beer tank temperature control, or a drive motor on a bottling line’s primary conveyor, a single unplanned failure during a production shift can cost far more in lost production than several years of sensor monitoring on that equipment. This calculation becomes even more compelling when equipment failure carries downstream consequences, such as product spoilage from a refrigeration failure, or contamination risk from a failed hygiene critical system.

    A realistic business case does not attempt to instrument every piece of equipment on a site simultaneously. It identifies the highest risk, highest consequence assets first, typically equipment that is both critical to production continuity and showing signs of age related unpredictability, and builds monitoring capability out from there based on demonstrated value.

    Interpreting the Data: Where Experience Still Matters

    Sensor data alone does not prevent breakdowns, it provides the information needed for an experienced engineer to make a maintenance decision. Distinguishing a genuine developing fault from normal equipment variation requires understanding of the specific equipment and process involved, and this is where the combination of sensor technology and genuine engineering experience becomes valuable. A vibration trend that would be alarming on one piece of equipment might be entirely normal on another, depending on its design, age, and duty cycle, and interpreting this correctly requires more than simply setting a generic alarm threshold.

    Common Mistakes When Getting Started

    Manufacturers new to predictive maintenance sometimes attempt to instrument too much equipment at once, purchasing sensors broadly across a facility without a clear plan for how the resulting data will actually be reviewed and acted upon. This tends to produce a large volume of trend data that nobody has the time or clear responsibility to properly monitor, undermining the value of the investment. A more effective approach starts narrow, with a small number of genuinely critical assets, and builds out review processes and alarm thresholds that are actually being used before expanding further.

    Another common mistake is setting generic alarm thresholds without adjusting them to the specific equipment and its normal operating variation, leading either to alarm fatigue from excessive false positives, or missed genuine faults because thresholds were set too conservatively. Getting this right typically requires an initial period of baseline data collection on each piece of monitored equipment, understanding what normal variation actually looks like, before finalising alarm settings that will be genuinely useful rather than noise. Working with an engineering partner who already understands the specific equipment involved shortens this baselining period considerably, since prior experience with similar assets provides a reasonable starting point rather than beginning entirely from scratch.

    A Practical Path Forward

    For FMCG manufacturers running a mix of ageing and newer production equipment, predictive maintenance does not need to be an all or nothing, large capital investment. Starting with targeted sensor installation on the highest risk equipment, integrated into existing Allen Bradley or Siemens PLC infrastructure, offers a practical, incremental path toward better visibility of equipment condition and fewer unplanned breakdowns. BevTech’s combined electrical, automation, and mechanical engineering capability means this kind of project can be scoped and delivered as a single, coordinated piece of work, from sensor selection and installation through to control system integration and alarm logic.

  • The Real Cost of Unplanned Breakdowns in FMCG Manufacturing

    The Real Cost of Unplanned Breakdowns in FMCG Manufacturing

    When an unplanned breakdown stops a production line, the first number most procurement and finance teams see is the repair invoice. It is also, almost always, the smallest number in the true cost of that breakdown. For FMCG manufacturers operating on tight production schedules and contractual delivery commitments, the real cost of unplanned downtime extends well beyond the technician’s callout fee and parts cost into a category of losses that are harder to see but considerably larger in total.

    The repair invoice is the smallest piece

    A breakdown repair invoice typically reflects labour hours and parts cost for the specific fix. What it does not reflect is the lost production during the stoppage, the idle labour cost of operators and packaging staff standing by while the line is down, the premium rate frequently charged for emergency callout response outside standard business hours, and the knock on disruption to the production schedule for the rest of the shift or day. A two hour electrical fault on a filling line does not just cost two hours of lost output, it can also delay the changeover scheduled immediately afterward, push despatch loading later than planned, and in some cases require overtime labour to recover the lost production before a despatch deadline.

    Contractual and customer relationship exposure

    FMCG manufacturers supplying major retail chains or beverage brand customers frequently operate under delivery commitments with real contractual consequences for missed despatch windows. A breakdown that delays a production run by even half a day can cascade into a missed delivery slot, which in some retail supply relationships carries financial penalties and in all cases carries reputational cost with a customer who has their own downstream commitments depending on reliable supply. This category of cost rarely appears on an internal maintenance cost report at all, since it shows up as a customer service issue or a sales team escalation rather than a maintenance line item, which makes it easy to systematically underweight when building the business case for maintenance investment.

    The hidden premium of reactive maintenance

    Beyond the direct cost of any single breakdown, a plant that operates primarily in reactive mode, fixing things only after they fail, pays a structural premium compared to a plant running a genuine preventative maintenance programme. Emergency callout rates for after hours electrical and mechanical support are typically higher than standard or scheduled maintenance rates. Reactive repairs are also more likely to involve a degree of guesswork or temporary fix under time pressure, increasing the likelihood of a repeat failure and a second round of breakdown cost for an issue that a planned, unhurried repair would have resolved properly the first time.

    Quality and compliance risk during breakdowns

    For beverage and food manufacturers specifically, certain breakdowns carry quality and compliance risk that compounds the financial cost further. A refrigeration control fault affecting temperature regulated product storage, or a CIP system failure that leaves cleaning standards unverified, can put product quality and food safety compliance at risk in ways that extend well beyond the immediate production line stoppage, potentially affecting product already in the supply chain and triggering a far more serious and costly response than a standard mechanical breakdown would.

    Building an accurate cost picture

    For procurement and operations teams looking to build an accurate breakdown cost figure to inform maintenance investment decisions, a useful approach is to track, over a representative period, the direct repair cost, the estimated lost production value based on line speed and contribution margin, idle labour cost during the stoppage, any despatch delay or customer service consequence, and any quality or compliance follow up cost where relevant. Summing these across a year of breakdown history typically reveals a total cost several multiples higher than the direct repair invoice total alone, which provides a much more compelling and accurate basis for evaluating investment in preventative maintenance, retained electrical coverage, or control system upgrades aimed at reducing breakdown frequency.

    Shifting the cost curve

    The practical response to this cost picture is not simply spending more on maintenance in general, but shifting spend deliberately from reactive, emergency response toward planned preventative maintenance, proactive electrical and mechanical audits, and where ageing control systems are a recurring fault source, targeted upgrades that address root causes rather than repeatedly patching symptoms. This shift typically reduces total maintenance and downtime cost even as planned maintenance spend increases, because the avoided breakdown cost, including its full hidden cost structure, outweighs the additional planned maintenance investment.

  • Preventative Maintenance Programs: Building a Business Case for Plant Managers

    Preventative Maintenance Programs: Building a Business Case for Plant Managers

    Almost every plant manager agrees, in principle, that preventative maintenance is preferable to reactive repair. Yet preventative maintenance programmes are frequently the first budget line trimmed when cost pressure increases, precisely because the value of preventative work is harder to demonstrate than the cost of performing it. A maintenance technician’s time spent on a scheduled inspection has an obvious, immediate cost. The breakdown that inspection prevented has no invoice attached to it, since it never happened, which makes preventative maintenance a perpetually difficult sell against budget pressure unless the business case is built deliberately and presented in terms that finance and procurement stakeholders find credible.

    Why the default business case often fails

    Plant managers advocating for preventative maintenance investment often default to a general argument about reliability and best practice, which, while true, does not give a finance stakeholder a number to evaluate against the cost of the programme. A more effective business case quantifies the avoided cost directly, drawing on the plant’s own breakdown history rather than industry generalities, since a specific, site grounded figure is far more persuasive than an abstract claim about the value of maintenance in general.

    Structuring the avoided cost calculation

    The core of a credible preventative maintenance business case is a comparison between the historical cost of reactive breakdowns on a specific piece of equipment or production line, and the estimated cost of a structured preventative programme designed to substantially reduce that breakdown frequency. This requires tracking, for the equipment in question, the frequency and direct cost of past breakdowns, the associated downtime and lost production value, and any pattern in failure cause that a preventative programme could realistically address, since not every failure mode is preventable through scheduled maintenance, some genuinely require redesign or replacement instead.

    Once this baseline is established, the preventative programme can be scoped specifically against it, targeting the failure modes most amenable to scheduled intervention, rather than proposing a generic, broad based maintenance schedule that may not address the plant’s actual highest cost failure patterns.

    What a well scoped programme includes

    An effective preventative maintenance programme for FMCG production equipment typically combines several elements. Scheduled mechanical inspection and servicing based on manufacturer recommendations and the plant’s own failure history, rather than a generic interval applied uniformly across all equipment regardless of actual duty cycle or criticality. Proactive electrical audits, checking for developing issues such as loose terminations, component degradation, or control system anomalies before they cause a fault, which is particularly valuable given that electrical faults are frequently among the harder failure modes to predict through purely mechanical inspection alone. Lubrication and wear component replacement on a planned schedule rather than waiting for failure, since planned replacement of a wear component during a scheduled stoppage is dramatically cheaper than the consequential cost of that component failing mid production. And condition monitoring where practical, using vibration, temperature, or control system data trends to flag developing issues between scheduled inspections.

    Prioritising critical assets first

    Not every piece of equipment warrants the same intensity of preventative maintenance investment. A useful prioritisation approach ranks equipment by the combination of breakdown likelihood and consequence severity, equipment that is both prone to failure and whose failure causes significant production or quality impact should receive the most intensive preventative attention, while equipment with low failure consequence, perhaps because of redundancy or low criticality to the overall line, can reasonably operate on a lighter maintenance schedule or even a run to failure strategy in some cases. This prioritisation makes the preventative maintenance budget go further by concentrating resourcing where the avoided cost return is highest.

    Presenting the business case

    When presenting a preventative maintenance investment proposal, the most persuasive structure leads with the historical breakdown cost for the targeted equipment or line, including the full cost picture of lost production, premium labour, and any downstream despatch or customer impact, followed by the proposed preventative programme cost, and finally the expected reduction in breakdown frequency based on the specific failure modes being addressed. This framing positions the preventative investment as a cost reduction measure rather than simply additional spend, which is a far easier proposition for finance and procurement stakeholders to approve.

  • Shutdown Support Planning: How to Minimise Production Loss During Scheduled Outages

    Shutdown Support Planning: How to Minimise Production Loss During Scheduled Outages

    Scheduled shutdown periods are one of the few windows in an FMCG plant’s calendar where major maintenance, upgrades, and electrical work can be performed without the constant pressure of an active production schedule running alongside it. They are also high stakes events, since a shutdown that overruns its planned duration delays production restart, and the production volume lost during an extended shutdown can quickly outweigh whatever cost was saved by trying to compress the shutdown scope or budget in the first place.

    Why shutdowns commonly overrun

    Shutdown overruns rarely come from a single dramatic failure. More often, they accumulate from a combination of underscoped work, where the actual condition of equipment once opened up reveals more required work than the original plan anticipated, poor sequencing between trades, where electrical, mechanical, and other contractors end up waiting on each other rather than working efficiently in parallel, and inadequate parts and materials planning, where a required component is discovered to be needed only once the shutdown is already underway, creating a delay while it is sourced.

    Scoping the shutdown accurately

    Accurate scoping starts well before the shutdown date, with a structured pre shutdown inspection of the equipment scheduled for work, to identify the actual condition and required scope rather than relying solely on the assumption that planned maintenance intervals translate directly into a fixed, predictable amount of work each time. Equipment that has shown developing issues in the preceding months, flagged through proactive electrical audits or condition monitoring, should be specifically scoped into the shutdown plan with contingency time allocated, since these are the items most likely to reveal additional required work once opened up.

    Sequencing for parallel work

    A shutdown plan that sequences electrical and mechanical work as a simple linear list, rather than mapping genuine dependencies between tasks, almost always wastes available time. Effective shutdown planning identifies which tasks can genuinely run in parallel across different trades and which have a true dependency, for example mechanical disassembly that must complete before an electrical technician can safely access a control panel, versus electrical and mechanical work on entirely separate parts of the line that have no actual dependency and could proceed simultaneously with the right trade resourcing in place. Having a single engineering partner capable of coordinating both mechanical and electrical work, rather than managing separate contractors with no shared visibility of the overall schedule, materially reduces this sequencing risk.

    Parts and materials readiness

    Nothing stalls a shutdown faster than discovering a required part is not on site once the relevant equipment is already disassembled. A disciplined shutdown plan confirms parts availability, ordering and receiving anything required well ahead of the shutdown date, including spares for components likely to be replaced based on the pre shutdown inspection findings, and ideally holding contingency stock for components with a meaningful chance of needing replacement based on observed condition, even if final confirmation only happens once the equipment is opened up during the shutdown itself.

    Safety and compliance work during shutdowns

    Shutdown periods are also a natural opportunity to complete machine safety upgrades, risk assessment remediation, and safety system corrective actions identified through prior audits, since this work often requires equipment to be offline in any case. Bundling safety remediation into the same shutdown window as other planned maintenance avoids a separate future production stoppage solely for safety work, provided the shutdown plan has allocated adequate time and trade resourcing for it alongside the core maintenance scope.

    Restart and verification

    A shutdown plan should also build in adequate time for restart and verification, rather than assuming the line will simply work correctly the moment the last task is marked complete. This includes functional testing of any control system or safety work performed, verification that mechanical work has not introduced new alignment or calibration issues, and a structured restart sequence that brings the line back to full speed in a controlled manner rather than attempting an immediate jump to full production rate, which tends to surface issues in the worst possible way, mid production rather than during a controlled test.

    Choosing a shutdown support partner

    The most valuable trait in a shutdown support partner is the ability to coordinate multi trade work under tight time pressure, drawing on genuine familiarity with the plant’s equipment and control systems rather than encountering them for the first time during the shutdown itself. Bevtech Engineering and Automation provides shutdown support spanning electrical, mechanical, and automation work for food and beverage manufacturers, with the breadth to coordinate complex multi trade shutdown scopes under a single accountable team.

  • Emergency Breakdown Response: What to Look for in an Engineering Partner

    Emergency Breakdown Response: What to Look for in an Engineering Partner

    A critical breakdown does not announce itself in advance, and the engineering partner a plant calls in that moment has an outsized influence on whether the resulting downtime is measured in hours or stretches into a multi shift production loss. Yet many FMCG manufacturers only evaluate their emergency breakdown response capability after a poor experience, when a slow, unfamiliar, or narrowly skilled contractor has already turned a contained fault into an extended outage.

    Response time is necessary but not sufficient

    Fast response time matters, but it is only useful if the responding technician can actually diagnose and resolve the issue once on site. A contractor who arrives quickly but is unfamiliar with the plant’s specific PLC platform, wiring history, or equipment configuration may still take considerably longer to resolve the fault than a slightly slower response from a technician who already understands the system. Procurement teams evaluating emergency response partners should weigh genuine resolution time, from initial call to line restart, rather than response time alone, which only measures arrival, not capability.

    Platform and equipment familiarity

    One of the strongest predictors of fast breakdown resolution is whether the responding engineer already has direct familiarity with the specific control platform and equipment involved. A technician who already knows whether a plant runs Allen Bradley or Siemens control architecture, who has previously worked on the plant’s specific filling, labelling, or refrigeration equipment, and who has access to prior fault history and documentation, will diagnose a recurring or related issue dramatically faster than a generalist contractor starting from zero. This is the strongest practical argument for maintaining an ongoing relationship with a single engineering partner for both planned maintenance and emergency response, rather than defaulting to whichever contractor happens to be available during a crisis.

    Multi disciplinary capability

    Production line breakdowns do not respect trade boundaries. A fault that initially presents as an electrical issue may ultimately trace back to a mechanical component, and a mechanical breakdown may have a control system element to its repair, particularly on automated equipment. An engineering partner with genuine multi disciplinary capability, combining electrical, mechanical, and automation expertise within a single accountable team, avoids the delay and finger pointing that can occur when separate electrical and mechanical contractors each insist the fault sits in the other’s domain, a surprisingly common and costly dynamic during high pressure breakdown situations.

    Availability matched to your production schedule

    For plants running extended or continuous shift production, emergency response capability needs to match the actual hours production runs, not standard business hours. A partner offering genuine 24/7 electrical shift coverage, rather than an after hours answering service that dispatches whichever contractor happens to be available, provides materially better protection for continuous production environments, since the responding technician is more likely to already be familiar with the site through their regular coverage role.

    The value of an existing maintenance relationship

    Plants that maintain an ongoing relationship with an engineering partner through planned preventative maintenance, proactive audits, and routine electrical and mechanical work consistently experience faster and more effective emergency breakdown response than plants relying purely on cold, one off emergency callouts. This is because the partner already holds institutional knowledge of the site, its equipment history, its known weak points, and its control system architecture, none of which needs to be rebuilt under the pressure of an active production stoppage. For procurement teams, this is a strong argument for consolidating planned and emergency maintenance with a single trusted partner rather than splitting routine work and emergency response across different providers on the assumption that this delivers better cost competition.

    Evaluating your current arrangement

    A useful exercise for operations and procurement leaders is to review the plant’s last several significant breakdowns and assess honestly how quickly each was resolved, how familiar the responding technician was with the equipment, and whether a different response arrangement could plausibly have reduced the downtime. This kind of retrospective review often reveals whether the current emergency response arrangement is genuinely fit for purpose or simply the default that has never been properly tested against alternatives.
