Air cooler CKP-302/9-ED
Application
Air coolers CKP-302/9-ED are designed for chambers with the volume of 10 to 250 m3, where apart from the temperature maintainance, is needed futher freezing of the goods. The advantage of these air coolers is a bigger range of the air thrown by fans, in contrast to air coolers from CPU series. Recommended range temperature in the chamber is from -25 to 0° C.
Fans and heaters
In the air coolers 302/9-ED were used fans of 300 mm. The fans motors are powered by a single-phase. They are thermally protected against coils' damages. All motors are connected to a hermetic junction box. The coil block and drain pan heaters are connected to a separate 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 mm. All air coolers from this series have a refrigerant distributor. Fin spacing is 9 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.
