Heated purge desiccant dryer uses compressed air as a purge, but its regeneration process also uses the energy from an external heater, so it costs moderate compressed air.

Reference performance:

Max. compressed air consumption: 6%
Max. inlet temperature: 45C, 113F
Max. inlet oil content: 0.01 ppm

High quality desiccant:

High performance desiccant
Pressure dew point: -20~-70C, -4~-94F
Max. pressure drop: 0.21 bar
Working pressure range: 4-10 bar, optimum: 7 bar/102 psi
Robust and compact design:

Forklift slots, lifting eyes
Controller:

Electronic control board
Time-based steering
Heater:

Made of stainless steel
Nickel-plated to avoid corrosion
Galvanized piping with flanged connections:

Easy maintenance and less chance of leakages
Butterfly valves:

Good quality butterfly valves
Filters (optional):

DP offer integrated filters for desiccant dryers
Pre-filters could eliminate oil contaminant from compressed air, increasing lifetime of desiccant.
After-filters could eliminate dust
