Flameless Vents

Flameless Explosion Venting by CV Technology

NFPA compliant flameless venting device.

the ultimate passive solution for applications when explosion venting is not possible.

Whether a vessel is located indoors or outdoors in an occupied area, flameless venting can used to provide explosion protection without the need to worry about the flame exhaust or pressure effects. Flameless vents are a truly passive solution with no contamination effects on the process they protect.

Flameless venting works by quenching the flame as it is exhausted into the flame arrestor. It eliminates the need to manage the flame exhaust while still relieving the pressure.

    Overview

    he Interceptor®-QR® and Interceptor®-LT™ are NFPA 68 compliant flameless venting devices. Flameless vents are comprised of two parts, an explosion vent and a quencher. The quencher is constructed of multiple layers of stainless steel mesh supported by a metal frame. Ignition inside a protected vessel causes pressure to build rapidly. The explosion vent is designed to relieve the pressure. Burning dust, flames and hot gases all exit through the vent opening into the quencher. The quencher then takes over to absorb the heat from the flame and hot gases. The mesh acts as a heat sink to quench the temperature and break the chain reaction of the explosion. The flame is completely retained in the quencher making flameless vents safe for indoor use or in occupied work spaces.

    Flameless vents are the ideal passive explosion mitigation device.


    Application

    Flameless vents can be used on a variety of process equipment. These vents are ideally designed to be used on equipment located indoors since they eliminate the release of a flame ball. Flameless vents are ideal for pneumatic conveying equipment, dust collectors, bins, cyclones, bucket elevator, mills, silos, and dryers.
