Being used in dust and product removal (Hoppers, Filterings) , pneumatic conveying systems (suction / compression) , careful removal (solid raw products) dosing systems, decoupling of two line systems, e.g. transmission from feed in to production. 

 

HAINKE-rupture disks have been developed especially for discharging dust explosions, as they protect the whole system and its surrounding workers from even starting the explosion right at start up of the plant. 

 

 

HAINKE Type ERB, spillway pipe, aka. explosion diverter, prevents durst explosions spreading via connection pipes. 

HAINKE check valve is designed to protect the upstream plant from pressure and fire during explosion within a pipe system. 

Designed for use with square/rectangular explosion vents, the flame quench technology consists of various layers of high temperature stainless steel which absorb heat produced during the combustion. This allows conventional venting to be done indoors with no release of flame.

In all compartments like hoppers, silos i.a. , where particulates are produced, processed, transportet and stored , the material is subject to explosions.

Reliable protection and safety systems are mandatory for operator and involved parties , let alone machinery. 
Relieve valves type EVN2.0  not only provide protection you can rely on, but are certified under regulation ATEX EN 16009 (flameless explosion venting with EC Type Approval according to EN 16009:2011)
