Benefits Available in 110 or 240v and have a flow rate of approximately 28 LPM (60 CFH) . Compact robust casing ensures maximum service life and minimal maintenance. Incorporated safety bursting disc in body which ruptures at 190 bar to safeguard the vaporiser from overpressure. Thermostatically-controlled element protected by a heat fuse ensures that the heater provides gas on-demand and cuts out during the rest periods. Neon indicator to show when element is heating. CE approved The Sirocco CO2 Welding Gas Pre Heater is designed to vaporise liquid carbon dioxide from syphon-type CO2 cylinders where a greater flow rate is required than is available from standard gas take-off cylinders. It heats the CO2 gas prior to entering the regulator to prevent damage to the regulator in high-flow applications. The Sirocco screws directly onto the cylinder valve by means of a loose CO2 nut and sealing washer. The outlet is threaded CO2 male to accept a CO2 pressure regulator. The body is forge
