The importance of leak testing The importance of leak testing
Leak detection is a key part of ensuring that the F-Gas Regulations do achieve what is expected of them. If a system doesn’t leak, it won’t require topping up, and this in turn helps the industry meet the phasedown under F-Gas. A retrofi t, with the gas out of the system, is a great opportunity to raise the bar on this.

Making sure a system doesn’t leak has never been more essential and this will clearly save the customer money in the l ong run. The route to success is to follow best practice, so relying on pressure, vacuum decay or using bubble spray won’t be enough. There are technologies available that can provide a high tech and economical solution.

All the standard system operating parameters should be checked to establish the benchmark temperatures and pressures.
I hope these tips on retrofi tting will prove helpful if you haven’t made the switch to a lower GWP gas yet. If you do get stuck contact your refrigerant supplier for advice. They have the expertise to ensure that your retrofi t goes as it should.
A-Gas has invested heavily in reclamation and recovery and this has been refl ected by the building of a new gas separator in Portbury and the launch of the A-Gas Rapid Recovery business in the UK. This bespoke, F-Gas compliant refrigerant recovery service off ers high recovery rates – approximately ten times faster than traditional recovery units.

Using a suitable detector, this method is 100 times more sensitive than bubble spray. Leaks can be detected in the smallest quantities and very quickly.

Monitor the system performance This is a crucial part of a retrofi t and you should start monitoring while the system is still running on R404A by recording the typical running conditions.

Disposing of the old refrigerant responsibly This is a legal obligation because it is classed as hazardous waste.
Under the F-Gas phasedown it is crucial that as much old refrigerant as possible is recovered, reprocessed and made available to the market.
You can be sure that reclaimed refrigerant is going to play a major part in keeping the supply chain moving.
