6.3. Return air cooler

F

A return air cooler is generally required in cases in which the return air temperature is over 65 °C (149°F).

A return air cooler improves the efficiency of the drying cells.

The return air cooler reduces the return air temperature to a defined value. The return air temperature is set at the operation panel.

&

The lower the value chosen for the return air temperature, the better the efficiency of the drying cells.

The dryer is automatically switched off if temperature exceeds 80 °C (176°F.)

Return air temperature is continuously monitored; the return air cooler is activated only when nee- ded. If the return air temperature exceeds the set value (e.g. due to interruption in the cooling wa- ter supply or soiling), an alarm message is given.

The return air cooler can be connected to a coolant circuit or to the water mains network.
