Witt Gas Techniques Ltd, the Warrington based gas safety, control, mixing and analysis equipment supplier has introduced a new ˜Super 85 Flashback Arrestor to enhance its existing range of ˜Super flashback arrestors for use on gas supply pipelines or gas reducing regulators with acetylene, butane, propane, natural gas, methane, hydrogen and oxygen as well as non-flammable gases.
Witt gas reported that this new flashback arrestor has an additional pressure sensitive cut-off valve, which will stop reverse gas flow and detect leaks upstream, it is slim in design and can therefore easily be fitted onto existing gas supply pipelines as it has a straight design and no offset connections.
Flashbacks are commonly caused by operator error and the use of flashback arrestors for operator safety is paramount. The ˜Super 85 has been designed to cut off the gas supply after every flashback or reverse gas flow, allowing the operator to resolve the cause. A visual warning is given, by the arrestors sleeve being released to show a red ring, indicating that the gas supply has been cut off. The operator can easily manually reset the device after he/she has resolved the cause.
In addition to the new feature, this flashback arrestor has all the normal features associated with Witt products, including the extinguishing of dangerous flashbacks using sintered stainless steel elements, a temperature sensitive cut-off valve to extinguish a sustained backfire, non-return valves to prevent the formation of explosive mixtures in the gas supply, protection against dirt contamination using a filter at the gas inlet.
