Design your own electric automatic shut-off device, by choosing the actuator and controller to suit your needs.

With the correct choice of actuator and controller up to six containers can be closed sequentially or two can be closed simultaneously. All combinations exceed the performance requirements and recommendations of  AS 2927:2019 for the storage and handling of liquefied chlorine gas.

Controllers can provide up to 12 different alarms and status signals including programmable relays and output options for SCADA or PLC systems.

All automatic shut-off systems prevent operators from having to enter a toxic environment to close a leaking valve and are supplied with an emergency stop panic button for remote activation.

The Terminator actuator is a safety device that automatically closes a chlorine cylinder or ton container valves in case of a leak.

The Terminator actuator uses the Gemini controller to provide power and logic to the actuator. The electric automatic shutoff device is fully automated and microprocessor controlled system can respond to a leak quickly and reduce exposure risk to operational personnel when a leak occurs.

According to the Australian Standard AS 2927:2019; the chlorine installation requirements at public swimming pools shall include an automatic shut-off device.
