198CD-60 Electrically Heated Flowmeter Regulator for CO2 is designed for applications requiring high gas flow rates, up to 60 SCFH without freezing. Thermostatically-controlled built-in electric heater keeps the CO2 warm and provides continuous duty cycle without freezing. 110VAC/190W heater is standard. Voltage output will vary in some locations. Flowmeter is back pressure compensated to ensure accurate reading when line restrictions are present. Forged brass body and housing cap. Sintered bronze inlet filter. CAUTION: Use this regulator only with non-siphoned standard CO2 cylinders.
