We have recently been asked to look at an Airwell VRF 3 Pipe Installation. Commissioned back in 2008/9. Systems have a history of bursting left hand side condenser coils. There are 10 Outdoor Units and 9 of these have had multiple replacement Condenser Coils replaced over recent years. Indoor Units are Airwell Ducted. Outdoor are Airwell (Sanyo Rebadged)

We recently replaced one of the Outdoor Units with the Sanyo / Panosonic latest model. We monitored all the date for 4 weeks and have had no further problems with bursting coil.

Have any of you Air Conditioning Engineers come across this issue with Airwell 3 Pipe VRF on UK Sites / Installations?

I would be very interested to know of your experiences and any other sites with the same issue. The customer in this case has spent a huge amount of money replacing condenser coils before we became involved.

Any feed back would be greatly appreciated
