These electric gas heaters are designed to reduce the problem of regulator icing as gas is withdrawn from carbon dioxide or nitrous oxide cylinders. They are thermostatically controlled with set points at 165°F (on) and 185°F (off). Units for carbon dioxide and nitrous oxide are equipped with CGA-connections for assembly between the cylinder valve and pressure regulator. They are also available with 1/4" FNPT connections for use with non-reactive gases.
