hi guy's

we've been asked to quote to replace some old kit in a path lab in a big hospital. However it's on R22 and they want it to be on some of that fancy new cold stuff like 404a

the pipe run is about 60 m and the install quality is such that it seems a real pity to rip it out..

now then is there anything around which would flush the pipes to a sufficient standard??

(and no we can't fit a mitsi wall mount!!)

cheers

richard
