Air & Water Cooled Chillers
TT-28500
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
