Hi guys hope everyone is well?
we have recently been asked to pipe up 6 of Stulz Minispace units DX to external condensers located 20m away. Having a 20m run I have sized the pipes at 7/8 and 5/8 which has been confirmed by Stulz. Turned up this am to be told we couldn't carry out hot work within the building. Job stopped. I really don't want to try forming nice neat bends using soft copper coils in 7/8 copper. The pipe run is quite busy and we have a lot of things to negotiate around. I've only ever used copper pipe and brazing or soft copper coils for smaller pipe sizes. Having been on the internet there seems to be a number of options out there ranging from ref lock aluminium to multi flex pipe. As I have next to no experience outside of copper I was hoping someone could advise me on the best solution. As I said it's a 20m run incorporating 10 bends in 7/8 and 5/8 pipe 2m rise so no need for oil traps. Any advise most welcome. Oh and it's on R407C
many thanks
Dave
