Abstract
Provided is a device for cleaning exhaust air from a printing device by means of a heat exchanger. The device is configured to operate the heat exchanger in a standard phase such that an output temperature of the exhaust air exhibits a standard value such that hydrocarbons are condensed out of the exhaust air. The device is also configured to operate the heat exchanger in a regeneration phase such that the output temperature of the exhaust air exhibits a value. The value is reduced relative to the standard value, such that water is condensed out of the exhaust air.
