Safeguard against emergency gas release

Hazardous release from gas cylinders poses a serious threat to environment and safety, owing to the high quantity of pressurised gas usually present in concentrated form. Gas leakages are known to have occurred: during transport of cylinders to factory; during storage of fresh cylinders; due to improper connection of fresh cylinder in gas cabinet; component failure, e.g. rupture of pressure regulator diaphragm; during storage of empty cylinders.

The CLEAN-PROTECT product line was specially developed to safely absorb large quantities of toxic, corrosive or pyrophoric gases during an emergency gas release incident. Two series of CLEAN-PROTECT are available active and passive.

Active systems are installed with an automatic valve bypass line. When a high hazardous gas concentration is detected by a gas sensor in any of the connected gas cabinets, the CLEAN-PROTECT controller automatically closes the bypass valve and opens the isolation valve to divert the contaminated exhaust through the CLEANSORB absorber bed where it is detoxified.

Passive systems are installed with the gas cabinet extract air flowing continuously through the chemisorbent bed. This safety installation guards against uncontrolled escape of those gases from up to ten gas cabinets.
