Revolutionary 908 thermostatic self closing mixers

05/07/2019

Mixers with thermostatic cartridge have been widely used for decades in the bathrooms of our houses, and in public facilities such as hospitals and sport centres, where they are used both as a single product (on the water output, with maximum comfort for the user who can adjust the temperature according to his personal preference), and as a system (mixer for communities with pre-set temperature by the provider).

Focussing on the more traditional mixers, they are normally equipped with a ceramic disc headvalve or a self closing cartridge for the opening and closing of water and a second rotary control with graduated scale adjusts the temperature.

A rotation lock with a button limits the water outlet temperature at 38 °C (UNI EN 1111:2017) to prevent scalding: in order to get higher temperatures, the button has to be pushed voluntarily.

The main function of the thermostatic cartridge is to adjust independently the supply of hot and cold water in order to provide it at the temperature chosen by the user.

Pursuant to the regulation, the water supply must stop or at least be reduced to the minimum in the event of a hot or cold supply failure. Failure to keep the set temperature, might cause the user serious injuries, especially if cold water supply is failing.

We might think the highest level of safety, comfort and efficiency has been achieved, but could we not do better? The answer is YES!

THE SERIES OF SELF CLOSING THERMOSTATIC MIXERS

IDRAL 908 series of self closing thermostatic mixers have been designed to improve the safety and comfort standards, with special attention to water and energy saving. This innovation is based on the self closing thermostatic cartridge (article 09090-T) that is the functional core of these mixers:

this cartridge combines in one single device the features of a thermostatic cartridge with the features of a timed adjustment of the water flow.

+ SAFE

The cartridge has been designed to comply with the English regulation TMV3, that defines significantly stricter safety criteria compared to the current European regulation UNI EN 1111:2017. The cartridge is designed to ensure the safety stop when one of the two water supplies fail, and is able to react very quickly to the pressure and temperature variations that may occur in the system.

Built with cutting-edge materials such as reinforced Nylon and Polysulphones, it ensures a combination of excellent mechanical and thermal properties, and unique anti-limescale attributes.

The maximum outlet temperature can also be adjusted via a rotating mechanical lock that is manufactory pre-set at 40°±1° and is not accessible to the user for safety reasons.

+ ERGONOMIC

The pressure release button allows to control the opening of the tap with a short stroke (1 mm) and reduces the pressure force necessary for its activation. The mixing is controlled by a simple rotating movement of the handle: it can therefore be adjusted using one hand, also thanks to the self closing feature.

+ VERSATILE IN THE RESEARCH FOR NEW DESIGNS

A single control allows to manufacture a thermostatic mixer with a design that until today was exclusive to the traditional “single-control” with ceramic disc cartridge, making room for the imagination of designers.

+ HYGIENIC

Designed to prevent water stagnation and with very smooth inner surfaces that avoid the deposit of impurities coming from the system thus preventing the proliferation of bacteria and biofilm.

In conclusion, the self closing thermostatic mixer is a significant step further in the water management for personal use, in terms of safety as well as cost and environmental savings.

With the purpose of keeping innovating and improving, IDRAL always go further in order to find new ways and to offer an increasingly better service to the customers, in line with their expectations and up to date with technological evolution and the surrounding world.
