All emergency showers located in different geographical areas in a facility are kept ready for 24-hour use with this system. Thanks to the circulation pump, water in the pipes is circulated and bacterial growth in the pipes is prevented and the user is provided with instant “TEPID” water. Thus, all showers in a facility are fed from a single tank at affordable costs. The heated or cooled water tank, circulation pump and water booster pump capacities vary according to the number of emergency showers to be installed in the facility and how many showers are required to operate simultaneously at the same time.
