Air cooler CPD-135/6-ED

Application

Air coolers CPD 6 mm are designed for chambers with the volume of 10 to 300 m3, where apart from the temperature maintainance, is needed futher cooling of the goods. The advantage of these air coolers is a dual-air thrown by fans, allowing for even distribution of air at the height of the air cooler in the chamber. Recommended range temperature in the chamber is from -20 to + 10° C.

Fans and heaters

In the air coolers CPD 6 mm were used fans of 300, 350, 400 and 450 mm. The fan motor is powered by a single-phase. It is thermally protected against coils' damages. Motors and heaters is connected to a one hermetic junction box. The amount and power of the heater match for the model of air cooler.

Coil block

The coil is made of profiled aluminum fins and a coil copper pipe with a diameter of 12,7 mm. All air coolers from this series have a refrigerant distributor. Fin spacing is 6 mm. All models in this series have a service valve on the suction pipe for the pressure measurement.

Special design

You can order an air cooler version resistant to the aggressive environment. For more information, please contact with your local distributor.
