Passive Explosion Protection

FENWAL’s passive explosion protection solutions consist of explosion relief vent(s) and self-acting isolation valve(s). These systems do not require explosion detectors or control systems. They rely on the pressure developed by the propagating deflagration to rapidly open the explosion relief vent and simultaneously close the isolation valve.

Explosion relief vents are designed to minimize damage to process vessels such as dust collectors, in the event of a deflagration involving combustible material. They are designed to meet the requirements of NFPA 68. The passive explosion isolation valve is a self-actuating device, which provides a mechanical barrier to mitigate the propagation of flame and burning materials between connected equipment. According to NFPA 654, where an explosion hazard exists, isolation devices shall be provided to prevent deflagration propagation between pieces of equipment connected by ductwork.
