Refrigerated Dryers
Cycling, non-cycling and subfreezing dryers
Refrigerated dryers deliver clean, dry air for most industrial uses, protecting systems and air-powered tools from moisture and contamination that could corrode or damage them.
Overview
Key Features
- Cycling: D-EC for lower energy use and cost of ownership, the larger DA Series, and a high-pressure model for demanding uses such as PET applications
- Nirvana range in varying cfm, including a large-capacity system with an insulated thermal mass and submerged evaporator holding a cold propylene glycol-water well, for continuous ISO Class 4 air at a 38 °F dew point
- Non-cycling: a variety of models to suit your industry and standards
- SF subfreezing: 212–247 cfm (360–420 m³/hr), ideal where piping or pneumatic equipment sees subfreezing temperatures

Dryers at a Glance
| Dryer | Pressure dew point | Choose it for |
|---|---|---|
| Refrigerated: cycling and non-cycling | As low as 3 °C (38 °F), ISO Class 4 | Most industrial applications, with lower investment, operating and maintenance cost |
| Refrigerated: SF subfreezing | Low-temperature operation | Systems with piping or pneumatic equipment exposed to subfreezing temperatures |
| Desiccant: heated | −40 °C (−40 °F) pressure dew point | Critical applications that need very low dew points |
| Desiccant: heatless modular | ISO Class 2, ISO Class 1 optional | Point-of-use drying with easy maintenance |
| HOC desiccant (H and HC Series) | −40 °C (−40 °F), continuous (HC Series) | Oil-free applications where energy cost matters most |
| IRDR rotary desiccant | Low dew point, continuous supply | Zero air consumption, low maintenance and noise below 50 dB |
