CO2 bottles

Steel cylinders filled with CO2 (carbon dioxide) are used in local releases (TAG)  of smoke and heat extraction systems or  in alarm boxes. They differ in filling quantity (weight) and connection thread. Common thread sizes are 1/2 UNF, M14 x 1.25 and M18 x x1.5. CO2 cylinders are available with or without a riser tube. A riser tube prevents icing when cylinders are installed vertically, ensuring that the cylinder volume is released more quickly. We also carry refilled cylinders. These may only have visual defects, but are technically in no way inferior to a "new" CO2 cartridge. Of course, refilled cylinders are approved and may be used without any problems.

CO2 cylinders must be checked annually. The weight is checked with the help of a scale (tare is indicated on each cylinder) and a visual inspection is carried out.
