Desiccant

40°F to -100°F are needed. Desiccant air dryers used desiccant beads such as activated alumina, silica gel or molecular sieves to absorb the moisture found in the compressed air stream. These dryers are usually used in industries such as: food, pharmaceuticals, painting, paper and petrochemicals that have very specific drying requirements.

DGH Series

DGH Series Heatless desiccant dryers open up a world of customizable performance opportunities with four standard ISO quality class levels of DGH Desiccant Dryerpressure dew points to choose from. Don’t settle for less than the ability to satisfy all of your requirements for clean, dry compressed air. A carefully engineered desiccant dryer design provides a reliable method to remove moisture as a water vapor. With the option to add coalescing filters, solid particles, liquid water droplets, liquid oil and oil vapors can be removed from the compressed air system in a reliable manner.

GHLD Series

GDHM Series

The GDHM Series desiccant air dryers use the proven “Pressure Swing Adsorption” (PSA) method for drying wet compressed air.  This requires having two identical towers containing hygroscopic desiccant. The unique design of the GDHM Series allows for the dryer to start and stop with a compressor or point-of-use equipment to eliminate purge loss when off.  The solid state memory feature allows the dryer to start where it left off in the drying cycle to prevent wet air downstream.

Other features:

  • 3 – 50 SCFM
  • Maximum Working Pressure: 150 PSIG
  • Maximum Inlet Temperature: 120°F
  • Pressure Dewpoints to -100°F
  • Solid state timer with LED display for visual monitoring
  • Low velocity air through the desiccant for more efficient drying
  • Large internal air passages to reduce pressure drop
  • NEMA 4 Components (protects against water spray and dust)
  • Minimal threaded connections, for fewer leak points than competitive units
  • Easy change out desiccant cartridges
  • Components are all easily serviced and field replaceable. (No special tools)

DPB Series

The DPB Series blower purge desiccant dryer process design offers the end user the opportunity to significantly reduce the energy costs associated with achieving a reliable -40°F (-40°C) pressure dew point. This is achieved by eliminating or reducing purge air requirements (compressed air utilized to regenerate desiccant beds) typical of other desiccant dryer designs.

Other features:

  • 500 – 4300 SCFM
  • Maximum Working Pressure: 150 PSIG
  • Maximum Inlet Temperature: 120°F
  • Cuts compressor purge air in half, saving energy
  • Durable and efficient blower
  • Large desiccant beds ensure consistent dew points
  • Packaged Filtration – Optional
  • ASME Code constructed and stamped pressure vessels standard
  • Optional energy saving demand controller provides an integrated humidity/temperature sensor from the on-line drying tower
  • Optional dewpoint monitor
  • Separate fill and drain ports
