Working Principle
Warm air from the refrigerated room is drawn into the evaporator.
The refrigerant inside the coil absorbs heat from the air.
Fans distribute cooled air evenly throughout the room.
Continuous circulation maintains the required storage temperature.
Result: High-capacity, energy-efficient cooling with uniform temperature distribution.
