18KW Water Heater For Swimming Pool & Bathtube Thermostat, Widely Application - THREE PHASE 380V_A

Flow-TEMP Sensor Technology: The system's sensor continuously measures temperature across the entire circuit and works with the control unit to keep the heating elements operating in a safe range while achieving the user-selected temperature. The design eliminates mechanical switches, removing failure points associated with moving parts. Sensor placement and operation prevent particulate build-up on sensing elements. By cutting down on unnecessary circulation cycles, the technology reduces energy consumption and extends the service life of the circulation pump.
