Evaporative coolers are used in the case of certain gas-cleaning processes, particularly in the cement industry. By injecting water which is subsequently evaporated, the temperature of the waste gas is lowered to the necessary level for the operation of an electrostatic precipitator or other components. The gas volume and the specific resistance of the dust in the gas are reduced.

Thanks to the synergy resulting from the combination of a practically maintenance-free electrostatic precipitator with a bag house; very low clean gas dust contents can be achieved at low energy costs. Our concept is especially designed for upgrades of existing electrostatic precipitators, where the casing and the first chamber can be reused.
