Working Principle
Warm air from the refrigerated space enters the evaporator.
The refrigerant absorbs heat through the stainless steel coil.
Fans distribute cooled air using either blow-through or draw-through airflow.
Continuous circulation maintains a stable and uniform room temperature.
Result: Efficient cooling, excellent hygiene, and reliable industrial refrigeration performance.
