Refrigeration Air Dryers AHT Series

PREMIUM REFRIGERATION DRYERS FOR HIGH INLET AIR TEMPERATURE

Flow rate: 33 ÷ 630 m3/h

The AHT range incorporates the pre-cooler, three-micron separator filter and refrigeration dryer designed based on the ACT range technology in a single unit.

The AHT range incorporates the pre-cooler, three-micron separator filter and refrigeration dryer designed based on the ACT range technology in a single unit. This dryer combines a heat exchange coil with copper pipes and aluminium cooling fins, a pre-filter from Friulair’s FT range, equipped with automatic condensate drain, and the aluminium ALU-DRY drying module. The product offers many advantages, which include a layout with vertical development that limits the footprint, high operating limits, machine management electronic controller (Industry 4.0 ready) condensate drainage management through two separate drainage devices managed directly by the control tool.


MAXIMUM WORKING CONDITIONS
