Non-Cycling Compressed Air Dryers

Product catalog summary

Overview: The DER Series Non-Cycling Refrigerated Dryers by General Air Products are designed to efficiently remove moisture from compressed air systems. These dryers feature large air-to-air heat exchangers, ensuring over half of the heat load is removed from the incoming air stream, which minimizes the refrigeration system size and reduces power requirements.

Key Features:

Dew Point: Guaranteed 33-39°F at nominal flow rate.
Energy Efficiency: Balanced design maximizes heat transfer while minimizing pressure drop.
Durability: Heat exchangers are resistant to fouling due to wide tube spacing and right-angle flow patterns.
Standard Equipment: Includes a hot gas bypass valve (models DER150 and up), adjustable timer-operated valve for automatic condensate removal, and a dew point indicator.
Environmental Considerations: Uses environmentally friendly refrigerant.
Warranty: 1-year warranty provided.

Technical Specifications:

Air Flow Capacity: Models range from 16 to 378 SCFM.
Connection Size: Varies from 1/2” to 2”.
Standard Voltage: 115/1/60 or 230/1/60 depending on the model.
Dimensions and Weight: Vary by model, with detailed specifications provided for each.
Operating Conditions: Minimum/maximum working pressure is 58/188 PSIG, and inlet temperature ranges from 50ºF to 110ºF.
Pressure Drop: Less than 5 psi.

Correction Factors: The document provides correction factors for inlet pressure, ambient temperature, air inlet temperature, and dew point to adjust dryer capacity under different operating conditions.
