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 takes place by detectors and ShieldControl. The ShieldControl fire detection panel is compliant with European and UL standards (EN 54-2, EN 54-4, EN 12094-1 and UL 864) and 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.
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.
The SHIELD fire safety solutions of Plymovent reduce the risk of fire to a minimum, and in the event of fire, ensures that any consequential damages are minor. The consequences of almost all incidences of fire will be limited to no or minimal system damage and the replacement of the filter cartridges and aerosol fire extinguishing generators.
Not only will the SHIELD fire safety solutions of Plymovent control fire risk in welding fume extraction systems, it also increases the lifespan of the filter cartridges and the entire system. Several institutes already tested and certified the SHIELD fire safety solutions of Plymovent.
