﻿TMV3 shower is valve is cool to the touch
The Securitherm cool-touch range of TMV3 shower valves from Douglas Delabie has been tested and certified by BuildCert to the NHS Model Engineering Specification D08/TMV3. The cool touch is achieved by passing the cold supply through an outer water channel before it is mixed with the incoming hot water. In addition, the water-supply inlets have thermally insulated covers. The shower temperature is factory set at 38°C and adjustable between 20 and 41°C.
To prevent scalding, the hot water is shut off if the cold supply fails. Smooth internal surfaces reduce the possibility of bio-film development.
For economy, an integrated device limits flow to 12 l/min.
