Air conditioning system with refrigerant R134a

Charging devices that do not require a permit

~1min read

Charging devices that do not require a permit are mobile charging devices into which pressurised gases are charged into compressed gas containers for exclusive use of one company.

Note:

Some air conditioner service devices are charging devices that do not require a permit. When these devices are used, the refrigerant is charged not into locally mobile compressed gas containers, but into a permanently installed charging cylinder with a visible contents gauge and float switch.

Recommendation:

When surplus refrigerant is transferred for one's own requirements, it is recommended that a portable charging cylinder with visible level gauge and pressure relief valve be used. Make sure to observe the corresponding technical rules (e.g. TRGS 400, TRGS 402, TRGS 407, TRGS 510, TRBS 3145/TRGS 725) when handling compressed gases and, in particular, when filling compressed gases from one compressed gas container into another one.
