Evaporator with Cooling Fan for Commercial Use Blast Cooler

The fan‑equipped evaporator is the core heat‑exchange assembly inside a commercial blast cooler. Composed of fin‑and‑tube heat exchange coils plus high‑speed cooling fans, this unit removes heat rapidly by refrigerant phase‑change and forced air circulation, achieving fast temperature pull‑down for food blast cooling, quick chilling and short‑term cold preservation in commercial food processing facilities.

Working Mechanism

Refrigerant (ammonia / CO₂ / synthetic refrigerant) enters the fin‑tube evaporator coil after throttling. Liquid refrigerant absorbs heat and vaporizes inside the tubes.

Built‑in high‑performance cooling fans force‑circulate air across the fin surface. Air transfers heat to cold coil fins, delivering chilled air into the blast cooler chamber.

Warm‑absorbed gaseous refrigerant flows back to the compressor for re‑processing within the closed refrigeration circuit.

Continuous high‑velocity air flow guarantees uniform temperature across the whole blast cooler space, avoiding local hot spots during fast cooling cycles.

For low‑temperature operation, automatic defrost function is integrated to eliminate frost accumulation on fins and maintain stable cooling capacity.
