Explosion protection

Our explosion protection technology

For maximum safety

HET Filter is a leader in the integration of explosion protection measures into filter systems to ensure the highest safety standards. Our approach to explosion protection comprises a comprehensive strategy based not only on the prevention of ignition sources, but also on the effective control of potential explosion hazards.

Our filter systems are not only electrically dissipative to prevent static charges, but are also designed so that they do not generate their own ignition sources. The constructive explosion protection of our systems is based on an explosion pressure shock-resistant design. This means that in the event of an explosion, the pressure within the system is controlled, with the filter cells acting as an effective flame arrester.

HET Filter’s innovative approach to explosion protection makes it possible to handle dusts with a specific maximum explosion pressure (pmax) of 10 bar. Even if a pressure surge occurs, the system is designed in such a way that the pressure is reduced internally to such an extent that it can withstand it. This internal pressure relief ensures that the filter system remains intact even in the event of an explosion and that the collected dust remains safely in the filter.

Our filter systems also comply with the ATEX Directive 2014/34/EU and numerous other relevant standards and directives. Our close cooperation with notified bodies ensures that we can offer the best possible explosion protection for our customers’ processes. At HET Filter, explosion protection is at the heart of our commitment to safety by continuously investing in advanced technologies and solutions to maximize protection against explosive hazards.
