The ALT ThermOne, distributed by Ad Waters, is a UPC-approved thermostatic shower valve that offers volume and temperature control with one single handle, just like a pressure balance. The THERMO-DRY thermostatic cartridge technology avoids any risk of hot/cold water cross-contamination and is factory preset for the hot water to never exceed 108 degrees F. A suitable solution for health care facilities and senior housing where laws require specific hot-water temperature control to prevent scalding, it can safely be used in any type of residential or commercial project, such as condominium and hotel projects with hot water and energy cost-saving objectives. The temperature is adjusted precisely, every time, no matter how cold or hot the water supply is during the year. 888-239-9336; www.alt-aqua.com.
