Maximising Gas Cylinder Efficiency with Eltherm Gas Bottle Heaters

Eltherm Gas Bottle Heaters

Efficient, Reliable Heating for Pressurised Gas Supply

Gas, one of the three fundamental states of matter, is highly compressible and typically stored in robust cylindrical or spherical containers. However, as gas is extracted—especially at high rates or low fill levels—bottle pressure can drop and condensation can form and freeze on the cylinder wall. This compromises performance, safety, and accuracy in gas supply systems.

Eltherm Gas Bottle Heaters, available from Thorne & Derrick, provide a reliable solution to these challenges by stabilising pressure, preventing freeze-up, and enabling complete cylinder discharge—essential when handling costly noble gases used in applications such as semiconductor manufacturing.

Why Use a Eltherm Gas Bottle Heater?

• Stable Pressure During Withdrawal
  As gas is withdrawn and vaporises, it cools the container. This can lead to freezing of the bottle and fittings, impairing gas flow. Eltherm heaters ensure consistent heat input to stabilise pressure and optimise flow rates.

• Maximum Cylinder Utilisation
  For expensive gases like argon or helium, it’s vital to empty cylinders fully. Without heating, residual gas may remain due to temperature-related inaccuracies in weight measurements. Eltherm heating mats maintain consistent temperatures, ensuring accurate readings from weighing systems and full use of gas contents.

• Prevention of Condensation and Ice Formation
  During continuous withdrawal, the bottle surface cools down, attracting and freezing ambient moisture. This is eliminated by applying controlled heat with an Eltherm heater.
