* Rates Flow Capacity - Conditions for rating dryers are in accordance with CAGI Standard ADF100: Refrigerated Compressed Air Dryers - Methods for testing and rating. Conditions for rating above dryers are: compressed air at dryer inlet: 100 psig (7kgf/cm2) and 100°F (38°C) saturated; ambient temperature: 100°F (38°C); operating on 60 Hz power supply. At rated conditions, pressure drop is less than 5 psi.
** At 35°F(2°C) evaorator and 100°F (38°C) ambient
All models use refrigerant R134a

Operating Conditions

Durability Delivered in the Smallest Package in its Class

Facilities with small-to-medium sized air systems simply want dry air, reliability and an affordable price. Deltech responds with the HG and HGE series non-cycling refrigerated air dryers that keep your air system at a dry, 38°F (+3°C) pressure dew point, from 10 through 500 scfm.

HG and HGE series dryers are built to last and take up as little space as possible. Sturdy sheet steel is formed and protected by an epoxy-based powder coat finish. Reliable reciprocating refigeration systems use environmentally friendly R-134a refrigerant. known for it's ability to maintain stable temperatures, R-143a protects the integrity of the 38°F (+3°C) pressure dew point.

HG & HGE Series - Standard Features

• Time saving package is easy to install. Simply connect the pipes and plug in the power cord (models HGE200-500 are hard-wired)
• Fully automatic operation adapts to your system needs without complicated controls
• Long service life is assured as every unit comes pre-assembled with quality components
• Maximum moisture is removed to a steady 38°F pressure dew point - every day
• On/off switch illuminates when compressor is on
• Colored dew point indication verifies performance (HG25-HGE500)

HG Series - Models through 50 scfm

• Static condenser recycles waste heat to eliminate cold, sweaty pipes
• Integral Moisutre Separator
• Timer operated drain includes isolation valve/strainer (float drain on HG10)
• Models HG10 and HG15 are designed to adapt to most popular HVAC installations

HGE Series - Models from 75 to 500 scfm

• Integral 304 stainless steel heat exchanger, mesh demister and, moisture separator for long life
• Timer operated drain includes isolation valve/strainer to protect valve from rust and scale
• Panel mounted drain timer controls (HGE200-500)
• LED style dew point indicator (HGE200-500)
• >Panel filter captures ambient dirt and dust to keep condenser clean (HGE100-500)

Models HG10 through HG50

Warm saturated air enters the Evaporator (A) where it is cooled by refrigerant being controlled by a Constant Pressure Expansion Valve (B). Water vapor condenses into a liquid for removal at the moisture separator (C) by an Automatic Drain (D). The cold, dry air is reheated as it passes through the Reheater (E), to prevent pipeline sweating. The static Condenser (F) eliminates the need for a cooling fan and simplifies the system. 

Models HGE75 through HGE500

Warm saturated air enters the air-to-air heat exchanger (A) where it is precooled by the outgoing chilled air, and then passes through the evaporator (B) where it is further cooled by the refrigeration system. Water vapor condenses into liquid droplets to be removed by the Moisture Separator (C) then, discharged from the dryer by an automatic drain (D). Chilled dry air returns through the air-to-air heat exchanger (A) where it is reheated before exiting the dryer.
