ODS & F-Gas leakage detection
Minimize Leakage of ODS & F-Gas: Leak Testing Requirements
F-Gas Leak Testing
Equipment which must be checked for leaks:
- stationary refrigeration equipment
- stationary air-conditioning equipment
- stationary heat pumps
- stationary fire protection equipment
- refrigeration units of refrigerated trucks and trailers
- electrical switchgear
- organic Rankine cycle
Responsibility
Equipment owner, rental companies, end user, service technicians who install, maintain or dispose of equipment.
