SED-72ZQ-J 72 kW clean-type electric steam generator (304 stainless steel series). Rated steam output 100 kg/h, saturated steam temperature 171°C, rated pressure 0.7 MPa. Heating is delivered by four 18 kW heater banks (
Funcionamiento
Resistive electrical heating: feed water (must be chloride-free, deionized) is pumped into a stainless boiler vessel; four parallel 316L SS heater elements (18 kW each, controlled in stages) heat the water to saturation pressure (0.7 MPa, 171°C). Multi-level water-level sensors prevent dry heating; dual pressure switches cut power if pressure exceeds set point; safety valve set at 0.73 MPa for full-open pressure relief; boiler-wall temperature sensor cuts power and alarms if wall temperature exceeds 165°C.
