Gas Detection Systems - Toxic Transmitters
Toxic Transmitters integrate with Powell Valve Closure Systems by measuring the level of unseen hazardous gas detected in the area. A signal is then sent to the receiver. The receiver sends the input to the Powell Valve Closure System Control Panel which activates the actuator to close the container valve. Within seconds from the time the unseen hazardous or combustible gas is detected, the container valve is closed, stopping what otherwise would have been a reportable release.
Powell Valve Closure Systems can be configured to respond to input from a variety of gas detection systems. Powell recommends the following toxic transmitters and gas detectors:
