Cold Room Fans, Lamps & Heaters
5 منتجThe electrical equipment inside a cold room works in the worst conditions on site: low temperature, high humidity, washdown, and long running hours. Fan motors are external rotor axial types, which means the blade mounts directly on the rotor and the assembly fits inside a tight evaporator housing — selection is at the duty point where the fan curve meets the system resistance, so the running current matters more than the nameplate figure. Lamps have to survive the same cold and stay sealed against condensation: LED reaches full output immediately at low temperature, where a fluorescent tube is dim for the first minutes. Defrost heaters keep the drain path open and the coil clear, and here the sizing rule is that too much power scorches the fins while too little leaves frost at the far end of the evaporator.
