TECHNICAL INFORMATION

Considering the specified features, specific CO₂ gas cylinders have been developed for SHEV applications that ensure safe operation either at -20°C and at +110°C.  The apparent density and the position of installation are of crucial importance here.
An “upside down” installation improves the escape of CO₂. Where this not possible, the use of gas cylinders with ascending pipe will have the same effect. All LBM pressurised gas cylinders additionally feature a predetermined breaking point (bursting disc) enabling the gas, in case of need, to escape into the system.

A precise quantity calculation is very complicated, so let us provide just a few basic details: Approx. 2g CO₂ are approx. 1l expanded gas. If a CO₂ gas cylinder with a volume of 20g is triggered at ambient temperature, in terms of figures, a working pressure of 10 bar is built up. After triggering, the system cools down a little bit, so that the final pressure is not immediately achieved. The operating pressure decreases at lower temperatures and considerably increases at higher temperatures.
