Industry context
Warehouses
For warehouses, refrigeration reliability is a commercial requirement rather than a convenience. Distribution cold storage holding palletised perishable stock. We keep the parts and refrigerant these failures usually need on the van.
Cape Town coverage

Prevention
Stop the fault returning
Schedule quarterly preventative maintenance on your walk-in cooler to catch wear before it becomes thermostat fault.
Keep condenser fins clean and airflow clear — the leading preventable cause of thermostat fault in warehouses cold chains.
Monitor cabinet temperatures daily and log deviations so thermostat fault is flagged before stock is lost.
Replace door seals at the first sign of perishing to stop the warm-air ingress that drives many thermostat fault callouts.
