Maintain brewery equipment with documented inspection, cleaning, lubrication, calibration, testing, and replacement schedules based on manufacturer instructions, operating hours, environment, and failure risk. Maintenance includes vessels, pumps, valves, heat exchangers, boilers or heaters, chillers, compressors, controls, packaging machines, and safety devices.

Assign every task to an owner and record completion, findings, and parts used. Correct small leaks, unusual noise, temperature drift, and damaged seals before they cause lost beer or unplanned downtime. Never bypass guards or safety devices to keep production running.

What Should Be Checked Every Day?

Daily checks can include leaks, abnormal sounds, pump seals, hose condition, valve operation, temperatures, pressures, glycol level, gas supply, alarms, drains, and visible cleanliness. Operators should compare readings with normal ranges.

Record exceptions rather than relying on memory. A slowly rising pump noise or chiller temperature can show a developing problem. Stop and escalate conditions that affect pressure safety, electrical safety, gas, chemical containment, product integrity, or rotating equipment.

How Often Should Gaskets and Seals Be Inspected?

Inspect gaskets during normal disassembly and at the interval specified for the component. Look for cuts, swelling, flattening, cracking, discoloration, odor retention, chemical attack, and loss of elasticity.

Replacement frequency depends on material, temperature, pressure, chemistry, mechanical movement, and cleaning. Store approved sizes and materials in clean packaging. Do not substitute an unknown elastomer because it fits. Incorrect seals can leak, contaminate product, or fail under temperature and chemical exposure.

How Are Pumps Maintained?

Check seal leakage, noise, vibration, motor current, coupling or alignment where applicable, mounting, flow, and pressure. Keep the pump from running dry unless its design permits it. Follow lubrication and seal-replacement instructions.

A sudden flow reduction can result from blockage, air entry, closed valves, damaged impeller, incorrect rotation, or process conditions. Isolate and depressurize equipment before service. Record pump model, seal type, and spare parts so the correct components are available during downtime.

How Are Sanitary Valves Maintained?

Inspect valve seats, stems, actuators, air lines, position feedback, clamps, and seals. Confirm full opening and closing without sticking. Disassemble and inspect manual valves according to the cleaning and maintenance procedure.

Automated valves need clean, dry air at the specified pressure and functional feedback. A valve can appear to move while failing to seat completely. Test critical routing and mix-proof functions before production. Replace worn seals and document orientation during reassembly.

How Should Heat Exchangers Be Maintained?

Monitor wort inlet and outlet temperature, cooling-water or glycol temperature, flow, pressure drop, and cleaning performance. Reduced heat transfer can indicate fouling, scale, blockage, air, or insufficient utility flow.

Clean using an approved procedure and compatible chemistry. Inspect plates, gaskets, frames, or tube bundles according to the design. Pressure-test or leak-check when required. Cross-contamination risk makes unexplained pressure or product changes important to investigate promptly.

How Are Fermenters and Bright Tanks Maintained?

Inspect manways, clamps, pressure gauges, temperature sensors, relief and vacuum devices, sample valves, racking arms, spray devices, cooling jackets, insulation, legs, and anchors. Look for leaks, corrosion, dents, and damaged cladding.

Verify pressure and temperature instruments on schedule. Keep spray devices open and correctly positioned. When maintaining brewing tanks, isolate pressure and energy before opening or removing components. Never enter a vessel without an approved confined-space program and qualified personnel.

How Is the Glycol System Maintained?

Check glycol concentration, level, temperature, pump operation, filters, strainers, expansion provisions, valves, insulation, pipe leaks, and tank control valves. Trend supply and return temperatures during peak load.

Incorrect concentration can reduce freeze protection or heat transfer. Air, blocked strainers, failed valves, and poor balancing create tanks that cool slowly. Repair wet or damaged insulation because condensation causes corrosion, dripping, and energy loss. Follow chiller maintenance requirements for condensers, refrigerant systems, and compressors.

How Are Boilers and Heating Systems Maintained?

Boilers, burners, electric elements, gas trains, steam traps, condensate systems, and safety controls require qualified maintenance. Follow manufacturer and local inspection requirements.

Monitor water treatment, scale, blowdown, flame or element condition, leaks, pressure, temperature, traps, and heating time. A slow heat-up may indicate fouling, failed elements, flooded jackets, low steam pressure, or burner problems. Do not adjust combustion or pressure controls without qualified authority.

How Often Should Instruments Be Calibrated?

Calibrate temperature, pressure, level, conductivity, flow, scales, and laboratory instruments according to risk, manufacturer guidance, use, and quality procedures. Critical control points may require more frequent checks than display-only instruments.

Use traceable reference devices where required and record as-found and as-left results. Investigate product made since the last acceptable calibration when an instrument is significantly out of tolerance. Label instruments with status and due date.

Which Spare Parts Should Be Kept?

Keep parts that fail regularly, stop production, have long lead times, or are difficult to substitute. Examples may include gaskets, pump seals, valve seats, sensors, relays, fuses, contactors, solenoids, actuators, hoses, clamps, heating elements, and critical packaging parts.

Build the list from the installed equipment and supplier recommendations. Record part numbers, compatible models, location, quantity, and reorder point. Store parts cleanly and protect elastomers and electronics from unsuitable conditions. A spare is useful only when staff can find and install it.

How Do You Build a Preventive Maintenance Plan?

List every asset, serial number, manual, criticality, task, interval, owner, tools, parts, safety steps, and expected downtime. Combine calendar intervals with operating hours, cycles, condition readings, and inspection findings.

Ask the brewery supplier for maintenance schedules, drawings, software backups, and recommended spares. Review failures and adjust intervals. Track downtime, repeat repairs, maintenance cost, and lost product. A useful plan prevents failures without creating unnecessary disassembly or production interruption.

What Maintenance Records Should Be Kept?

Record the asset, date, operating hours or cycles, task, measurements, findings, parts, technician, downtime, and follow-up work. Attach photographs and calibration results when useful. Keep safety inspections and pressure-device records according to applicable requirements.

Use records to identify repeat failures, rising vibration, longer heating or cooling times, and parts consumed too frequently. Update procedures after proven improvements. Maintenance history also helps suppliers diagnose problems and supports better decisions when equipment should be repaired, upgraded, or replaced.
