Compressed heat purge desiccant dryer uses the heat from compressed air itself to regenerate, so external heater is not required, and it barely costs compressed air.

Reference performance:

Max. Compressed air consumption: 0~1%
Max. Inlet temperature: 120~170°c, 248~338°f
Max. Inlet oil content: 0.1 ppm
Max. Working pressure: 10 bar; optimum: 7 bar; various working pressure is customizable

High quality desiccant:

High performance desiccant
Pressure dew point: -20~-70°c, -4~-94°f
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
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
