Air & water Cooled Chillers


The TT-28500 range comprises air cooled portable units with or without heating elements and water cooled units. All are rated at 28 kW.

  • Compressor switches on and off automatically to maintain set temperature - circulation pump runs continuously
  • Self-optimising microprocessor controller with digital display of set and actual temperature
  • Electronic control of compressor operating time for extended working life
  • All components in contact with water are stainless steel or bronze Anti-freeze thermostat prevents freezing
  • Automatic or manual refill
  • Automatic level control with pre-warning at low water level Indication lamps for thermal relay of pump and compressor, anti-freeze, low and high pressure and high temperature
  • Audible alarm in case of failure
