Air Blast Coolers - Liquid-Air Units » AB Range

7.5 to 150kW

Description

Air Blast Process Coolers - Re-circulating coolant passes through air blown heat exchange radiators where process heat is transferred to ambient.

Our AB range of self contained dry coolers are non-refrigerated cooling systems. They are a cost-effective alternative to recirculating chillers for applications where precise temperature control and cooling below ambient temperature are not required. Typically, coolant will be delivered back to the process at approximately 10C above ambient, however, this is variable dependant on process load and external conditions.

Units are supplied as standard with an impressive array of safety features and are suitable for indoor and outdoor location.

Applications

  • High frequency generators
  • Resistance welding machines
  • Induction furnaces

Standard features

  • Both single and three phase models are supplied complete with motor protection, circuit breakers and on/off switches
  • Temperature gauge
  • Pressure gauge
  • Coolant safety by-pass

Options

  • Full ranges of fail-safe process machine interfacing devices are available on request
  • Frost protection package
  • Automatic coolant refill
  • Remote start facility
  • Non-standard voltages and frequencies
  • Variable speed fans
  • Deionised compatible water circuit
