The CH-5 Chiller Unit
The CH-5 Chiller Unit is designed for use in conjunction with the TECAL 140H Calibrator to achieve
calibration temperatures down to -40°C. Chilled water pumped through the heatsinks on the Tecal
140 units 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 arti cially 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 deionized water.
The CH-5 can also be used to pass cooling water through the cooling coil on the Calibration Baths
(LCB) and Cooling Probe (7032395); minimum temperature +10°C.
