Our filling of gas cartridges is controlled with the greatest of care. An automated weight control on the production line weighs each indervidual cartridge. The cartridge is then tested for leaks by immersing it in a 55 oC water bath for three minutes. If the cartridge weight is wrong or if gas is leaking during the test, its automatically removed from the production line. The various saftey steps in the process guarantee the highest quality for our customers. Our Refillable cylinders are manufactured from high quality steel, treated with corrosion protection and fitted with self closing valves and intergrated safety valve.
