The Techne CH-5 Chiller Unit is designed for use in conjunction with the TECAL 140 H&S Calibrators to achieve calibration temperatures down to -40°C. Chilled water pumped through the Heatsinks on the Tecal 140 units to allow the Tecal to reach -40°C. In normal ambient temperatures of up to 20°C the minimum temperature obtainable with the TECAL 140 models is 45°C below ambient; by artificially cooling the heatsink of the units with water from the chiller -40°C can be obtained.

The unit is designed to run on distilled or deionised water.

The CH-5 can also be used to pass cooling water through the cooling coil on the Calibration Baths (LCB) and Cooling Probe (FDB00CP); minimum temperature +10°C.
