SPECIFICATIONS: Refrigerant: R134a Maximum Inlet Pressure: 250 psig Maximum Inlet Temperature: 120°F Minimum Ambient Temperature: 50°F Maximum Ambient Temperature 110°F OPERATION: Under normal conditions, the air dryer will run continuously when power is on. The dryer will provide a specified pressure dew point for the compressed air system with little maintenance or adjustments required. - Page 3 Ambient Conditions: A. Indoor installation is recommended. Dryers installed outdoors must be well protected from precipitation, dust, dirt, debris and animals. B. The unit should be installed in a well ventilated area. Ambient temperature must be in the temperature range of 50°F to 110°F. C.
- Page 4 moisture removal and temperature variation demands on the refrigerated dryer. Between the compressed air receiver and dryer, a general purpose coalescing filter with an automatic drain is used to remove liquid water, liquid oil and solid particles from the airstream. Pre-filtering eases the load on the dryer and prevents an emulsion of water, oil and particulates from forming.
- Page 5 AIR & REFRIGERANT CIRCUITS: Air Circuit Warm wet compressed air enters the refrigerant dryer at the inlet port. (On models 30 scfm through 250 scfm) It first passes through an air-to-air heat exchanger where its temperature is lowered by the cool air exiting the dryer. It then enters the evaporator or refrigerant-to-air heat exchanger where its temperature is lowered.
