Thermostatic mixers have been developed to distribute hot water safely and comfortably. Suitable for use in a mixing center, for example, in gyms, hotels, hospitals, it can serve multipoint distribution. The water temperature is fixed at 38°C through a safety lock on the wheel, and for a temperature above that mark it is necessary to activate the safety lock, however the temperature is not higher than 49°C. This temperature control is only possible due to the high thermal sensitivity cartridge that keeps the water at exactly the desired temperature and is easily controllable.
