Wallace & Tiernan® Emergency Shutoff Drive is the additional safety measure for your chlorine gas application.
The automatic Emergency Shutoff Drive (ESD) for chlorine gas applications ensures the immediate closure of a connected chlorine gas source in the event of a gas leak. The ESD reliably closes the chlorine gas valves within 3 seconds, reducing the total possible chlorine leakage time. The device works in connection with a chlorine gas warning device and provides additional safety for the operating personnel.
The device can be easily installed directly on the chlorine gas valve of each storage tank and is controlled from a standardised electrical control cabinet. The valve automatically closes upon receipt of a closure signal and features an auto test button which enables you to test the function of each connected valve prior to leaving an unmanned site. A battery integrated in the control cabinet ensures the function even in the event of a power failure. In addition, the ESD can be triggered manually on the control cabinet located outside the storage room using the emergency switch. After securing the environment and eliminating a possible leak, a trained operator must manually re-open the chlorine gas valves.
Wallace & Tiernan® Systems offer the GMS plus system, a flexible two channel measuring system designed for gas and temperature monitoring in up to two rooms.
