Description
The Hydra-Sentinel is an automatic chlorine shut-off device for chlorine cylinders and drums in water and wastewater treatment plants. It meets the performance requirements and recommendations of AS 2927:2019 for the storage and handling of liquefied chlorine gas.
The shutdown system is designed as an additional line of defence to an approved safety plan. It automatically shuts the primary isolation valves on the containers if a significant gaseous chlorine leak is detected. The system may be supplied with an integral chlorine leak detector if required. According to Australian Standard AS 2927:2019; the chlorine installation requirements at public swimming pools shall include an automatic shut-off device.
The control unit includes integral power supply and battery backup. An air regulator provides air at 600 kPa to a maximum of 8 actuator arm assemblies. Each arm is clamped directly to a chlorine container valve.
The chlorine shut-off device protects plant and equipment from accelerated corrosion caused by chlorine gas escape while the installation is unmanned. It also supplements and enhances the protection of operating personnel against exposure to chlorine gas (and/or other toxic gases).
