Solenoid valves for leak detection

With the risk of such large-scale damage, financial and health implications, fitting leak detection systems should be something of serious consideration for commercial and large domestic property owners or managers. Leak detection systems have been available and fitted to properties for some time, however there is now a smarter solution with wireless point to point control. These digital solutions also detect water leaks immediately, shut off the water supply, and therefore limit the damage as much as possible

Danfoss has partnered with Quensus – a specialist in intelligent water management – to offer a simple solution that meets BREEAM requirements for the control of the flow of water, including optional water leak detection capabilities.

Featuring Danfoss solenoid valves, the system can be either hard-wired or wireless, using either wired or wireless PIR sensors or energy harvesting technology for both switches and sensors. The PIR sensors detect when a person enters the room and communicate with the Danfoss solenoid valves to open and turn the water supply on for a pre-set length of time. Once the room is vacated, the power is cut off and the valve closes, avoiding potential water wastage and damage due to overflows.

Another advantage to this wireless technology is that light switches and water detection sensors can be installed without mains power.  Removing mains electrical fittings from high-risk water leak areas ensures that areas such as washrooms are as safe as possible as there is no risk to life from low voltage detection sensors encountering water.
