Where this equipment is used
Walk-in freezers are insulated panel rooms operating at sub-zero temperatures for frozen storage. Defrost system health is critical to their reliability.
Freezer rooms work at lower temperatures where ice build-up is a constant threat. The defrost system — heaters, timer and drain heater — must work correctly or the evaporator freezes solid and the room warms. Door seals and door heaters also matter more than in cold rooms.
Common faults on this equipment
- Ice build-up on the evaporator
