Heat Exchanger
The heat exchanger (HTX1) is normally a liquid-to-air unit made of copper
tubing and copper headers. There are primary and secondary fans to cool the
unit. The fans are controlled by temperature sensor TS1 (shown in
A stainless steel liquid-to-liquid plate type exchanger is also available.
If the temperature is less than 32 °C (90 °F), the fans will not run. The primary
fan will start when the temperature reaches 38 °C (100 °F). The secondary fan
will start when the temperature reaches 44 °C (110 °F).
