Cold Storage & Refrigeration Maintenance Guide
Refrigeration systems degrade slowly and fail suddenly. A structured preventive-maintenance plan keeps SEC (kWh/m³/yr) within 5% of commissioning values and extends plant life beyond 20 years.
Combine time-based PM (compressors, condensers, valves), condition-based PM (vibration, oil, current draw) and predictive analytics from IoT sensors. Budget 2–4% of capex per year.
Preventive maintenance intervals
Weekly visual + IoT dashboard review, monthly condenser cleaning, quarterly compressor oil sample, annual overhauls, 5-year major overhaul.
Predictive maintenance
Vibration on compressors, oil analysis, current signature analysis, sub-cooler ΔT trending, evaporator discharge temperature drift.
Refrigerant leak management
F-gas Regulation (EU) 517/2014 checks every 3–12 months by charge size; leak detection sensors in machine rooms; annual reconciliation.
Spares strategy
Critical spares on-site (contactors, expansion valves, oil filters), OEM spares within 48-h logistics, refrigerant top-up stock.
KPIs to track
SEC (kWh/m³/yr), pull-down time, refrigerant top-up %, unplanned downtime hours, mean time between failure (MTBF).
