10 to 500 scfm Basic
Refrigerated Compressed
Air Dryers
For facilities with small to medium sized
air systems that simply want
dry air, reliability and an affordable price.

• Properly treated compressed air increases productivity and minimizes downtime.

• Deltech HG and HGE Series are non-cycling refrigerated compressed air dryers that keep your air sysstem at a dry 38°F (+3°C)  pressure dew point, from 10 throuh 500 scfm.

• Deltech HG and HGE Series dryers use refrigeration cooling to condense entrained moisture out of your air system.

• Time saving package is easy to install.

• Condensate is removed from the air stream by an automatic drain valve.

• Fully automatic operation adapts to your system needs without complicated controls.

• Dew Point indication verifies performance (HG25-HGE500)

• Models HGE75 - HGE500 utilize a stainless steel chevron plate angle heat exchanger that provides high heat transfer and low fouling risk.

How Deltech HG/HGE Series Refrigerated Air Dryers Work

Models HG10 through HG50

• Warm, saturated air enters the evaporator where it is cooled by refrigerant being controlled by a constant pressure expansion valve.
• Water vapor condenses into a liquid for removal at the moisture separator by an automatic drain. 
• The cold, dry air is reheated as it passed through the reheater, to prevent pipleline sweating.
• The static condenser eliminated the need for a cooling fan and simplifies the system.

Models HGE75 through HGE500

• Warm, saturated air enters the air-to-air heat exchanger where is it precooled by the outgoing chilled air, and then passes through the evaporator where it is further cooled by the refrigeration system. 
• Water vapor condenses into liguid droplets to be removed by the moisture separator and discharged from the dryer by an automatic drain.
• Chilled dry air returns through the air-to-air heat exchanger where it is reheated before exiting the dryer.
