The Titan Controls® C02 120 V Inline Heater is designed to prevent C02 regulator freeze-up and avoid cracking the internal diaphragm of the regulator due to high flow conditions. The C02 Heater is installed between the C02 cylinder valve and the regulator, and warms the gas stream allowing for increased flow rates without regulator freeze-up. The C02 Heater may be used in conjunction with a Titan Controls C02 Greenhouse Regulator or any other C02 regulator system. Comes with aluminum case and solid brass expansion chamber, solid brass fittings for C02 cylinders, CGA 320 and NEMA 5-15 grounded power cord. 100 watts | 115 Volts, 50/60 hertz, single phase | 90 scfh maximum.
