No-touch taps are the most hygienic option available for hand washing. This is a very important aspect for everybody, but of increased importance where people are handling food, or where cross contamination needs to be avoided.
DVS no-touch taps have been extensively developed and tested to achieve the current high levels of reliability. James Paget Hospital said We first started trialling Dart Valley
Systems automatic taps over two years ago they have been totally reliable and are good value for money. Whilst the main consideration is hygiene to avoid cross contamination, automatic taps also make significant savings on water.
Electronic taps use the optimum amount of water. DVS normally fi t a 5 litre flow reducing aerator (ECA approved) on the spout to control the flow of water and the taps only run when the hands are placed under the spout, limiting the water use to the precise time required and preventing taps being left running.
How they work
All DVS no-touch taps include highly intelligent electronics, giving ultimate flexibility over sensor ranges and run times. Taps can be pre-set prior to delivery or adjusted on-site using a hand held controller. All taps feature a chlorination option for new installations or where flushing is required and a built in purge facility, ideal for areas where water condition is critical. A number of helpful reporting features can also be accessed via the hand held controller, including the number of tap operations and purges which have occurred.
Infra red detection
All electronics are housed within the body of the tap. A separate solenoid valve controls the flow of water and is connected to the tap using secure IP65 rated connection cables. The power supply or battery pack are also connected in the same way. When a user puts their hands under the tap the infra red detector activates the solenoid valve, causing it to open. The valve remains open while the users hands are under the tap allowing them to wash their hands thoroughly. Once the user removes their hands the sensor activates the solenoid valve to close and the water flow is stopped. All DVS taps have an anti-vandal mode ensuring that if someone deliberately blocks the sensor, the tap will only run for one minute. The sensor will then lock off until the sensor has been cleared and the tap then resets, preventing water wastage and the risk of overflow.
