Wallace & Tiernan® Emergency Shutoff Drive is the additional safety measure for your chlorine gas application.
Evoqua's Emergency Shutoff Drive (ESD) ensures the highest level of safety for chlorine gas applications. The fast-acting safety device can immediately close a connected chlorine gas source in the event of a gas leak. Working in connection with a chlorine gas warning device, the ESD reliably closes chlorine gas valves within a designed objective of 3 seconds or less, reducing the total possible chlorine leakage time.
The device is easy to install directly on the chlorine gas valve of each storage tank and is controlled from a standardized electrical control cabinet. The valve automatically closes upon receipt of a closure signal and features an auto test button, enabling you to test the function of each connected valve before leaving an unmanned site.
In the event of a power supply failure, safety is ensured by an integrated, 12-hour standard battery backup, which has a 24-hour extended option. 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.
Online gas monitor providing a flexible and reliable self testing detection system.
