These units are used in safety critical areas where dust or gas ignition is likely to be catastrophic.

Areas can be classified as ATEX, Explosion Proof Eexd, and Intrinsically Safe IS areas which take safety precautions even further.

The HPUs can be supplied with certified Electric Motors, Pumps, Valves, Drive Couplings, Switches, and Instrumentation depending on how stringent the ATEX area rating is.
