Fire risk under control in welding fume extraction systems
Plymovent presents SHIELD fire safety solutions. This range of products reduces the risk of filter fires in the metalworking industry to a minimum. In addition, the products are designed to minimise consequential damage. Early detection and suppression are initiated in the event of a starting fire, to limit system damage and avoid the risk of escalation and accumulation of smoke throughout your workshop.
Fire is a serious risk and often occurs spontaneously in filters. Some welding and cutting applications have a higher risk of causing fire than others, due to such factors as high temperatures, large amount of sparks or a low flash point.
Features
- Reduce the risk of fire to a minimum
- Detect possible fire starters
- Suppress starting fires immediately
- Reduce system damage to a minimum
- Minimise replacement, maintenance and filter downtime in case of fire
- Increase the effectiveness and lifespan of your entire extraction system
The SHIELD programme contains several components that combine to create a system solution. Each product has its own unique features and benefits. As every factory is different, Plymovent can specifically advise on how to control the fire risk in your workshop. Plymovent designs a system solution, tailored to your specific welding applications and requirements.
Prevention
As prevention method Plymovent offers the patent pending products SparkShield and OilShield. SparkShield is an in-line spark arrester that prevents sparks, spatters and cigarette butts from entering the ductwork and reaching the combustible filter cartridge and debris in the dustbin. OilShield was developed especially for oily welding applications. It is highly recommended for applications using low flash point oils, such as punching oils. This limestone feeder mixes limestone with oil, decreasing the remains’ combustibility.
Detection
Detection takes place by detectors and ShieldControl. The ShieldControl fire detection panel features an open or short-circuit monitoring of the connection cables to the detectors and the FlameShield extinguishing devices. If one of the detectors is activated ShieldControl responses adequately and stops the airflow immediately and activates the suppression methods.
Suppression
Plymovent offers two suppression methods: sliding valves and FlameShield. The sliding valves stop the supply of oxygen and isolate the fire, minimising consequential damage. FlameShield is an aerosol fire extinguishing generator that is released immediately after the sliding valves are closed, extinguishing the fire in the filter housing rapidly.
