The Titan Controls CO2 heater was designed to prevent CO2 regulator freeze-up and avoid cracking the internal diaphragm of the regulator due to high flow conditions. The CO2 Heater is installed between the CO2 cylinder valve and the regulator and warms the gas stream allowing for increased flow rates without regulator freeze-up. The CO2 Heater may be used in conjunction with a Titan Controls CO2 Greenhouse Regulator or any other CO2 regulator system. Manufactured in USA with aluminum case and solid brass expansion chamber. Solid brass fittings for CO2 cylinders, CGA 320. Completely enclosed heating element. Not for use on GFI protected circuits. 1 Amp/120 Volts/60 Hz.
