Cassette-type heat exchanger with pre-heating of cooling air up to 590C (1,100F).

The cooling air must be preheated if there is any risk of the temperature on the cooling elements dropping below the acid dew point when cooling hot process gases. Nederman has consequently developed the cassette-type KU cooler specifically for cooling such gases.

Unlike the KS coolers, the KU unit features an additional temperature controller for preheating the cooling air. Part of the heated cooling air and fresh air is jointly drawn in by the cooling air fan and mixed. The present mixing temperature is adjusted by automatically opening or closing the fresh-air flap before the air stream enters the cooling elements.
