All refrigeration systems should be checked for leaks for a number of reasons:
- Concern over the environment
- Cost of replacing lost refrigerant
- Legislation to phase out and ban CFC’s
- A low refrigerant charge will lead to a reduction in system performance – could be costly.
It is now a legal requirement that a system with over 3kg of refrigerant should be checked for leaks on an annual basis. (Article 17) This means making leak detection part of an on going maintenance programme.
