Liquid-Air Units » AF Range

AF Range: Dry air to liquid coolers 50 to 500 kW

Description

Flatbed air blast cooler, incorporating heat exchanger and axial fans to cool the water, water/glycol or any known refrigerant to give optimum fluid cooling to typically 10°C above ambient.

Fans

High efficiency, low noise, low power consumption, constructed from lightweight non-corrosive polypropylene. Complete with blade side guard.

Heat exchanger

Manufactured using high efficiency double corrugated aluminum fin matrix with copper tubes. All circuitry is carefully selected to give optimum transfer capability. Optional fin materials are available to suit aggressive environments.

Pump pack module (optional)

Self contained system complete with non-ferrous/ stainless steel pump, expansion tank and fused control circuit housed within powder coated weatherproof enclosure.

Options

  • Variable speed fan
  • Sequenced step control
  • 'V' Bed arrangement
  • Vertical coil orientation
  • Stainless steel casework
  • Extra low noise model
  • Coated fins
