AHT

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

  • Ambient temperature: + 50°C
  • Inlet air pressure: 16 barg (ACT3÷18) - 14 barg
  • Inlet air temperature: + 100°C

Data refer to the following nominal condition: ambient temperature + 32 °C; inlet air pressure 7 barg; inlet air temperature +80 °C.

  • ALU DRY aluminium heat exchanger                                     
  • High-efficiency compressor
  • Generously sized condenser unit
  • DMC34 digital controller RS485 modbus
  • Refrigerant compressor thermal or thermo-ammeter protection
  • Automatic condensation pressure control
  • High compressor temperature protection (from AHT 30)
  • Refrigerant high- and low-pressure safety pressure switches (from AHT 80)
  • Hot gas bypass valve
  • Timed condensation drain
  • Aftercooler
  • Pre-filter installed between AFR and HE
  • On request models with different Power Supply and different connections [Ph/V/Hz]
  • On request higher flow rates and pressures
