SPX Deltech HG25-115 Non-Cycling Refrigerated Compressed Air Dryer 25 SCFM

SPX Deltech HG25-115 Non-Cycling Refrigerated Compressed Air Dryer 25 SCFM

The SPX Deltech HG25-115 is a non-cycling refrigerated compressed air dryer rated at 25 SCFM at 100 PSIG and 100°F. It removes moisture from compressed air lines by cooling the air through a refrigeration circuit, causing water vapor to condense and drain, then reheating the dried air before it returns to the system. Unlike cycling-type dryers, non-cycling units run the refrigeration compressor continuously, making them straightforward and well-suited for applications with consistent air demand.

Applications

Refrigerated compressed air dryers like the HG25-115 are standard equipment in industrial compressed air systems wherever moisture in the air line would cause problems — including pneumatic controls, spray finishing, food and beverage processing, pharmaceutical manufacturing, and general manufacturing facilities. The HG25-115's 25 SCFM capacity makes it suited for small-to-medium compressor systems, typically paired with a reciprocating or rotary screw compressor in the 5–10 HP range. Non-cycling refrigerated dryers are widely used because they have no complex unloading mechanism and maintain a consistent pressure dew point across varying loads. The timed automatic condensate drain eliminates the need for manual draining, which is important in continuous-duty industrial environments. SPX Deltech (a brand within the SPX Flow portfolio) has been a long-standing manufacturer of compressed air treatment equipment including refrigerated dryers, desiccant dryers, filters, and coalescers.
