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
Figure 282 ).
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).
