Engine Protection

HOERBIGER supplies Explosion Relief valves to protect combustion engines from devastating effects of oil- mist or gas explosions. Together with core engine manufacturers, we have developed appropriate safety systems that are still setting standards today.

Independent of the industry, whether on Marine, Power Generation or Land-based energy applications, we are prepared to offer an appropriate, certified solution.

Crankcase

Regardless of the engine type, the hazard of a potential oil mist explosion in the crankcase is always present. Therefore, proper protection is mandatory for both, people and equipment.

HOERBIGER Crankcase Relief valves are a reusable, flameless venting device, protecting personnel and equipment. For 4-stroke engines the HOERBIGER valve series “EVO” and for 2-stroke engines the HOERBIGER valve series “EVX” set the standards.

Manifold

Engines which burn low flash point fuels, have in case of back- or misfire a potential explosion risk in the inlet and exhaust manifolds.

HOERBIGER Manifold Relief valves are a reusable, flameless venting device, protecting personnel and equipment. The HOERBIGER valve series “EVT” protect both, the engine inlet manifold and the engine exhaust manifold in case of back- or mis-fire.
