Gas pre heaters

For gas cylinders and manifold systems


Elektrotermija produces heaters for inert and non-corrosive gases. Gas pre heater is thermostatically controlled and designed to prevent gas regulator freezing and gas diaphragm cracking due to high flow conditions. It extends service life of regulator and prevents malfunctions or interruptions. This heater is installed between the gas cylinder and the regulator, and warms the gas stream allowing increased flow. The operator should allow a time period of 5-10 minutes for warming up before turning on gas. The heating element is protected by a stainless steel housing, but is not intended for outdoor use. Housing can get hot during use, so avoid touching and keep it away from combustible materials. Heater is equipped with power connection cable and with threaded fittings for the different gas types. To provide a secure connection and prevent gas leaks, use new washers when changing cylinders.


  • Gas cylinders, gas bundles, gas manifolds
  • Welding, medicine, packaging
  • Argon, Carbon Dioxide, Nitrous Oxide, Oxygen, Nitrogen
