Sherman Engineering is the regional manufacturer’s representative for SPX Deltech.


Deltech cabinet style refrigerated dryers provide the most cost effective method of dew point control for dehydrating compressed air systems. Designed for applications above the freezing point of water, each Series is custom crafted to best meet your unique compressed air treatment applications. All Deltech refrigerated dryers incorporate these:

  • Environmentally friendly "NO CFC" refrigerants and dependable hermetically sealed refrigeration compressors for long life
  • Fully automatic condensate drain valves for the lowest possible dew point under all rated design conditions - without freeze-ups
  • Automatic condensate drain valves for fast, reliable condensate removal
  • Rugged sheet metal cabinets blanketed with polyester-based powder coat paint for protection from harsh environments

Deltech desiccant dryers deliver superior dew point control to -100°F for critical applications. Energy efficient designs deliver maximum value across a full range of flow rates to best meet your unique compressed air requirements. All Deltech desiccant dryers incorporate these same quality features:

  • Highly hygroscopic desiccants combine spherical uniformity with superior crush strength to deliver stable dew point control and low dust migration
  • Process quality switching valves deliver consistent repeatability to ensure system integrity and long component life cycles
  • Precision timing circuits control process valve sequencing protocols to deliver optimum dew point stability and energy efficiency
  • Calculated desiccant bed construction ensures ideal tower velocities to adsorb moisture, stabilize dew points, and prevent bed movement
  • Spare muffler(s) are included on all models and sizes

Dirt, rust, pipe scale, water and lubricant are all by-products of compressed air generation. Left unfiltered, this abrasive stream of contaminants will compromise the operation, integrity, and usable service life of pneumatically powered operations.

Unnecessary wear and tear artificially inflates operating costs, adds to product rejects, and wastes countless hours on unscheduled equipment maintenance. Furthermore, the presence of oily water dilutes the effectiveness of in-line oil lubricators. Combined, these unwanted contaminants bind valves and motion control devices, corrode air motors, and contaminate finished goods. Quality Deltech Filtration products will protect your processes and systems, reduce power costs and help improve your bottom line.
