Hiller decanters and plants are used in many applications that require explosion protection. The designs are based on ATEX stipulations. Hiller GmbH offers its customers the advantage here of many years of experience in meeting a variety of process requirements. Hiller ATEX Anlage We design the entire plant specifically for the customer's application; this can extend from use in an explosion-proof environment for zones 1 and 2 through to a solution for processing flammable or toxic media via inertisation. In this process, the oxygen in the air within the centrifuge and seals is replaced with inert gas.
