Desiccant Air Dryer

GXF+ Blower Purge Desiccant Air Dryers

Adekom's GXF+ blower purge desiccant air dryers are designed for outstanding industrial performance and a long lifetime of reliable operation. They eliminate moisture completely before it can cause any damage to your compressed air net or production equipment. GXF+ dryers use a combination of air from an external blower, heat and minimal compressed air, and incorporate unique, patented technological innovations and energy-saving options. GXF+ dryers are available in a range of sizes with a guaranteed dewpoint down to -40°C /-40°F (optionally -70°C/-100°F) and come in an IP54 protected cubicle.

Features Specifications Application

High reliability
GXF+ dryers eliminate system failures, production downtime and costly repairs by removing moisture from compressed air with a pressure dewpoint as low as -40°C/-100°F. Up to 30% desiccant overfill and the long lifetime of the desiccant further enhance reliability.
Maximum energy savings
GXF+ dryers incorporate energy-saving features that cut your carbon footprint. A low pressure drop below 0.2 bar/2.9 psi drives down energy costs. Dewpoint sensing and control adapts the energy consumption to the real load of the dryer.
Easy installation
Your GXF+ dryer is delivered ready for use with heaters, sensors and the control unit already wired and connected.
Advanced control and monitoring
The advanced PLC control and monitoring system gives clear indication of dryer status, operation cycle and alarms. It includes alarms for low inlet pressure, blower, heater and valve operation, plus limit switches, pressure and temperature sensors.
Minimum maintenance
All internal components are easily accessible to facilitate maintenance. The use of high-grade desiccant and high-quality valves assumes long maintenance intervals.

Functional diagram for the GXF desiccant dryer
Blower purge desiccant air dryers
The blower sucks in ambient air and blows it across the external heating element. The heated air is then guided from top to bottom through the saturated desiccant and absorbs the adsorbed moisture
Cooling
Purge: After the heating, the hot tower desiccant is cooled. Cooling is done by expanding dry compressed air from the outlet of the adsorbing vessel over the hot reactivated tower, from top to bottom, and thus released.
Zero purge (Option): After the heating, the hot tower desiccant is cooled. Cooling is done by sending air from the hot vessel over a cooler and back into the hot tower, from bottom to top.
