sed Plates..


The plates you are selling from the 80's probably used R12 refrigerant and mineral oil. This is NOT comaptable with 134A and PAG oil. They will need to be scrubbed metioucsly of any oil from the old system before reinstalled in a new instalation.

Another problem may be the swagelock fittings. Are they all in GREAT shape, no distortions, nicks, etc from removal from icebox? This will make a new leakproof instalationa a chore.

If there is not enough copper to remake the swagelock ends, they may need to be sent back to Seafrost for a new set of copper coils. This is about $150 a coil.

Used holding plates can be a great deal if it fits your bill. Or scrap it out for the scrap copper since there is a fair amount of copper in these two plates.

Just some honest advice from observations in the field.

Have you told Cleve at Seafrost what an idiot he is?

Cleve walked me through this process of converting my R-12 system to 134 by cleaning out the tubes (if I recall with mineral spirits) and then vacuuming out all the residue with a vacuum pump. It worked fantastic and my engine drive system works great now, having been converted to 134. And I did this in place without removing the plates from the boat.
The plates for sale are obviously out of the boat and would be even easier to clean.
Perhaps your butchering of old systems has resulted in the problems you suggest but it doesn't have to be that way.

Cleve has detailed to me the number of 'refrigeration techs' that are clueless.

Thanks for the 'help'.

Looks like the show's over folks. A first round knockout. I want my money back. And surely someone in the big US of A wants those plates now.
