Hydraulics for explosion hazardous areas

The various regional explosion protection directives such as 2014/34/EU (ATEX), IECEx, NEC... influence the selection, installation, use and maintenance of equipment in potentially explosive atmospheres. HAWE Hydraulik has been developing and producing product ranges specifically for this purpose for many years and has them tested and certified by independent institutes. However, explosion protection is only guaranteed if the equipment is used as intended and in accordance with the operating and installation instructions. Details on the certifications can be found in the operating instructions B ATEX.
