EC Regulation 842/ 2006 on certain fluorinated greenhouse gases

Article three of the regulation requires the 'operator' to prevent leakage of fluorinated gases, to repair any detected as soon as possible and check the leak repair within a month to ensure it has been effective.

Article three also sets out the following timetable for systems to be checked for leaks: at least every 12 months for systems charged with more than 3kg of fluorinated gas (hermetically sealed systems 6kg); every six months for systems carrying 30kg or more; every three months for systems containing 300kg or more. Monitoring equipment is required for systems of 300kg plus and should be tested annually.

If monitoring equipment is connected to systems with less than 30kg of fluorinated gas, the leak testing regime is halved. The dates and results of all leakage checks need to be logged by the operator.

Leak detection gases

  • BOC provides engineers with 2 gases for pressure testing and to aid leak detection.
  • A new nitrogen/helium mixture with a smaller molecular composition is better able to detect very small leaks. (click on additional info links for further info on these gases)
  • The leak detection mix is supplied by BOC in an easy to carry cylinder filled to 200bar (1.3m3) and fitted with a standard industrial valve outlet.

The key benefits of the BOC mix include:

Improved detection

The leak detection mix can detect much smaller leaks due to the size of the test gas molecules. Because helium molecules are far smaller than nitrogen they are better able to pick up small leaks in a refrigeration system. BOC recommends that customers use the package for auditing refrigeration systems before they commit to any new service contract.

Safe and easy to use

Inert and non-flammable the leak detection mix is compatible with all standard pressure testing equipment (including nitrogen regulators) and is suitable for leak testing any size of refrigeration system. Leaks are detected with a helium sensor available from BOC Gas and Gear outlets or trading partner, HRP

Cost effective

By reducing the amount of refrigerant gas lost from the system, the better leak detection gas will reduce the number as well as the cost of callouts by customers.
