Refrigerant dryers

FLEX Series

The FLEX refrigerated air dryers deliver stable dew points, high energy efficiency and long-lasting durability through stainless steel plate heat exchangers and a compact 3-in-1 structure. Integrated moisture separation, reduced pressure drops and simplified controls ensure reliable, clean compressed air across all industrial applications.

Efficiency

Energy efficient

The 3-in-1 stainless steel plate exchanger minimizes losses and boosts thermal efficiency, giving stable dew points and lower power use.

Durability

High lifecycle

Robust stainless components resist corrosion, ensuring long‑term performance, stable operation, and reliability over time.

Control

Smart monitoring

Digital controls offer clear dewpoint indication and drain valve management, simplifying maintenance and daily operation.

PRODUCT OVERVIEW

High efficiency drying for varied air systems

The refrigerated air dryers from the FLEX range provide reliable, clean compressed air through an integrated stainless-steel heat exchange system that maintains stable dew points and minimizes energy consumption. Designed for broad industrial use, these dryers combine a compact footprint with strong cooling performance, making both integration and assimilation simple. 

 
Their 3-in-1 architecture merges separator, reheater, and evaporator into a single module, reducing piping, pressure losses and installation complexity. High efficiency condensers on larger models further optimize heat rejection and durability. With clear digital control interfaces, the FLEX series supports consistent, efficient plant operation while ensuring long equipment life and dependable moisture removal.
