Compressed Air Treatment
Dryers & Air Treatment

The right compressed air treatment products will help you keep your air compressors performing at their best. Compressed air contains water vapor and as it travels through compressed air piping, it cools and the vapor condenses into liquid condensate. This condensate increases maintenance requirements and affects product quality.

Refrigerated Air Dryers

Energy Saving Sustainability The FLEX Series lowers air system power costs and improves productivity by matching power consumption to compressed air demand. In a typical manufacturing facility, up to 30% of electricity consumed is for generating and treating compressed air. To reduce total cost of operation and qualify for utility company incentive programs, proper air treatment equipment selection and application is required.


Compressed air load profiles in most manufacturing facilities fluctuate. The FLEX Series provides cost-effective energy savings by matching electrical power consumed in direct proportion to air demand. Linear load matching is achieved from 0% up to 100% demand. Non-cycling dryers operate with the refrigeration compressor running continuously, regardless of inlet load conditions. Minimal energy savings are realized from 100% down to 0% inlet air load.


The FLEX Series dryers automatically cycle (on /off) the refrigeration compressor in response to inlet load conditions. As the inlet air load is reduced, the power requirement to dry the air is matched in proportion to the demand. For example, at 60% inlet air load, a non-cycling dryer consumes 96% of the full load power consumption, a 4% energy savings. By comparison, at 60% inlet air load, the FLEX Series consumes only 60 % of the full load power, a 40% energy savings.

Regenerative Air Dryers

Utilizing twin towers filled with premium grade activated alumina, Deltech Heatless dryers are available with three application specific control systems designed to meet the needs of specific industrial applications with economy and performance. Industries such as pharmaceutical manufacturing, laboratories, hospitals, microelectronics, food packaging, paper, glass and powder painting with low dew point requirements, utilize heatless desiccant air dryers.

Precision Performance


  • Consistent outlet pressure dew points
  • Premium grade desiccant beads enhance surface area and have high crush strength
  • Large desiccant beds ensure 4.8 seconds of contact time
  • Large flow diffusers ensure even flow distribution through the bed and eliminate channeling
  • Towers are designed to prevent fluidization of the desiccant
  • Up-flow drying allows water and heavy contaminants to drop out of the air stream
  • Simple discharge of contaminants
  • Cleanable stainless steel flow diffusers/support screens
  • Separate fill and drain ports for ease of desiccant replacement
