Hi all, thanks for looking!
I just bought a new (to me) commercial salmon troller. This boat came with a very simple engine-driven refer unit - but the previous owner says it has always leaked, and it's not been in service for a few years now.
A Sanden 508 compressor pumps the refrigerant via a 3/8 tube into a seawater cooled condenser, from there to the THX, then 1/2 stainless tubing (approx. 60-80') inside the insulated fishbox that's full of seawater, and then back to the compressor in 1/2" tubing. (for expediency of this post, I'm omitting data on all other peripheral items)
Old owner says he could never chase down the leak, so my first suspect is the condenser - because the sniffer won't detect a leak inside the boat if the refrigerant escapes overboard via the cooling water.
I have no problems replacing the condenser - the system has zero pressure now, all the refrigerant that could have vented into the atmosphere has done so years ago...
And I have refer guys who can help me start the system back up later - but nobody has saltwater experience. How do you determine if seawater has entered the system, and what to do then?
I'd hate to throw good money after bad & replace hundreds of Dollars worth of parts & then have everything break down a couple hours later.....
Any suggestions would be appreciated.
