equipment exhaust air temperature. The unit will increase or decrease the speed of the fans to keep
the equipment exhaust at the desired temperature.
The appropriate fan speed is based on the equipment’s inlet air temperature and its temperature
differential. The temperature differential is the rise in temperature between the inlet air and the
exhaust air after it passes through the equipment. Refer to your equipment manual to determine the
temperature differential.
