A drum heater or gas bottle heater is mainly used to heat the media inside and keep them at a certain temperature. The heating reduces the viscosity of various liquids and enables better pumping and filling. Additionally, it prevents crystallization and flocculation. The heating elements provide uniform temperature distribution and also enable melting of solids. The heating of the gas bottles is mainly used for temperature control and pressure stabilization, but also to prevent ice formation. In the case of particularly high-grade gas, the heat is required to achieve complete emptying of the bottle.
