The purification of heavily loaded exhaust air is very often essential for plant operation. Safety of the working environment and adherence to legal regulations (TA-Luft) define the specifications for the choice of appropriate aggregates. Many years of experience enable the Scheidt process engineering unit to successfully support the user in choice and design of the required equipment. The Scheidt Ventilatoren GmbH offers a wide choice of mist collectors, single or multi-level exhaust air scrubbers, chrome evaporators and scrubbing and absorption towers in a variety of designs and models.
