Nano technology provides point-of-use safety
DELABIE is pleased to announce the launch of its TMV3 approved point-of-use thermostatic mixing valve the Premix NANO. Its compact design is ideal for under basin installation to deliver safe, mixed water for one or two basin taps, or alternatively to supply one shower.
Legionella control
With a major focus on balancing the risk of Legionella versus scalding, the new HSG 274 part 2 guidelines recommend fitting a type 3 thermostatic mixing valve (TMV) to washbasins and sinks for high risk users i.e. very young, very elderly, infirm, mentally disabled and physically disabled. The TMV should be installed as close as possible to the point-of-use to minimise dead legs and reduce bacterial development. Due to its compact size – the Premix NANO is less than 8cm in length – it fits discreetly under a basin, or close to the delivery point for showers, either behind a panel or in the roof space. As with all DELABIE’s TMVs, it is also possible to undertake thermal shocks. A 5mm Allen key is all that is required to allow hot water up to 85°C to pass through both hot and cold water channels.
Scalding safety
Despite its size, the Premix NANO is extremely precise. Pre-set at the factory at 38°C, the installer can adjust the mixed water from 34° to 60°C. It will regulate any variation in temperature, pressure and flow rate to deliver safe, stable mixed water in any installation. Moreover, its automatic failsafe is active for both the hot and cold water, ensuring automatic shut-off if either the hot or cold water supply fails. Certified by Buildcert and WRAS, the Premix NANO is approved to NHS Estate D08 specifications.
Sustainability
As specifiers and facilities managers look to reduce water and energy consumption, flow regulators are becoming more prevalent. To comply with the BREEAM exemplary rating, for example, basin taps must be able to demonstrate a 65% saving against a baseline of 12 litres per minute (lpm). The Premix Nano has a minimum required flow rate of 3 lpm, one of the lowest on the market, and is capable of supplying a stand-alone outlet in BREEAM approved installations.
