Shield fire safety Solutions Fire risk under control in welding fume extraction systems

Do you control the risk of fire at your workplace? We do. Plymovent presents SHIELD fire safety solutions1. This range of products reduces the risk of filter fires in the metalworking industry to a minimum. These products are designed to prevent fire and to minimise consequential damage in the unlikely event of a fire. SHIELD products are divided into three categories: products to prevent fire, detect fire and suppress fire. Smoke, heat and sparks are detected at the earliest stages to minimise system damage and to avoid the fire from spreading and smoke from accumulating in the workshop....

■■ OilShield feeds limestone into the ductwork, where it mixes with oil/oily fumes, decreasing the combustibility of oil and preventing spontaneous combustion. Engineered solution The SHIELD programme contains several components that can be combined to create a system solution. Each product has its own unique features and benefits. Features Shield fire safety solutions ■■ Reduce the risk of fire to a minimum. ■■ Detect possible fire starters As every factory is different, Plymovent can specifically advise on how to control the fire risk in your workshop. We can design the system solution...

Prevention • Prevention • Prevention • Prevention • Prevention Sparks are well known as a potential ignition source leading to fires in the metalworking industry. Welding fume extraction systems without a specific spark arrester may allow sparks, spatter and dust to reach the filter cartridge(s) and debris in the dustbin. Plymovent developed SparkShield* in order to prevent such fires. SparkShield SparkShield is a compact in-line spark arrester which requires little or no floor space. Its design is highly effective in the removal of sparks. In addition, SparkShield is also very suitable as...

Prevention • Prevention • Prevention • Prevention • Prevention oilshield Features The OilShield unit doses the limestone, and the booster fan on top extracts the limestone and transports it into the main ductwork.After the limestone has absorbed the oil from the welding fumes, the resulting mixture becomes easy to filter. ■■ Reduces the risk of fire When cleaning –by reverse pulsing– takes place inside the filter unit, the mixture falls down into the dustbin below. This way, OilShield reduces the risk of fire not only inside the filtration system but also in the debris within the dustbin....

Detection • Detection • Detection • Detection • Detection • Detection shieldcontrol ShieldControl is an important component of the entire detection programme. The connection cables to the detectors and the FlameShield extinguishing devices are monitored for open circuits and short circuits. In the event of a cable circuit failure, ShieldControl activates a warning signal. ShieldControl includes a battery pack to ensure that in the event of a power failure the detectors remain operational and that the fire extinguishing devices are activated in the event of a fire. This fire detection panel...

Sliding valves The reliable detection equipment of the SHIELD programme quickly activates the suppression products, which are designed to suppress and extinguish any fire. The main purpose of the sliding valves is to isolate the fire at an early stage by closing the sliding valves in the main ductwork. In the event of a fire –less than five seconds after detection– the fan is switched off, the filter cleaning system is shut down and the filter is isolated by the sliding valves. The fire is isolated, cut off from any source of oxygen or airflow.The fire is suppressed and goes out. The risks...

Fire risk under control Plymovent understands the causes of fire at different welding applications in the metalworking industry better than anyone. Our SHIELD programme, combined with our know-how and field experience, allows us to offer you a tailor-made solution that will keep fire risks under control. The SHIELD fire safety solutions of Plymovent reduce the risk of fire to a minimum, and in the event of a fire, ensure that any consequential damage is minor. The consequences of almost all incidences of fire will be limited, with little or no system damage and just the replacement of the...
