Companies that work with dust that is emitted into the air through various applications are required to, according to NFPA and ATEX directives, determine through a risk assessment whether the dust is combustible and a potential explosion threat. This type of dust is a danger to the employees and the infrastructure nearby; should a combustible dust particle come into contact with a spark this can cause an explosion that can harm employees and destroy infrastructure.
If a company does determine that their dust is combustible, they are required to install preventive measures to stop or control a potential dust explosion. Dust collectors, storage vessels and enclose conveying systems that help to contain the combustible dust, need to be fitted with explosion vents to relieve the pressure build-up should an explosion occur.
Envirox supplies quality explosion vents that are used within various industries to control an explosion should one occur, keeping safe staff and infrastructure. Envirox supplies both rectangular flat venting devices, and rectangular domed venting devices:
Rectangular domed venting devices:
- Include PTFE insulation in a triple stainless-steel construction.
- High vacuum, resistance within devices with operating temperatures of up to 240°C
- The VMP SU is suitable for devices with pressure shocks
Rectangular flat venting devices:
- Flat, single-layer stainless steel construction
- Installed without the upper flange
- Suitable for low operating pressures
- Can work within operating temperatures of up to 100°C
- On request, the VMP F can be customised to have a curved radius
Both venting devices:
- Have high efficiency and reliability
- Have a long lifespan
- Are resistant to abrasion, mechanical particle impacts and weather conditions
- Are simple and easy installation
- Have a variability static activation pressure, and
- Spare parts are available for purchase or exchange
For more information on venting devices to be used to help prevent and control combustible dust explosions, Envirox is on hand to offer a solution. With years of experience within various industries, Envirox offers practical and efficient advice to all dust collecting needs.
