Frigoboat Keel Cooler in the tropics

[Richard Kollmann]

What are the causes Frigoboat is tell you for this system’s serious problems we read about? Is it because of excessive compressor heat? Is heat causing O rings to change shape or design of line connector? Or are they blaming contamination when replenishing lost refrigerant on personal qualifications? How do they explain refrigerant flow problems on five year and older systems? They surely cannot deny all of these problems.

We spent a couple of weeks on the hard with it and found it not too difficult to rig up a drip system to keep the refer running. Basicly a tupperware braced over the keel cooler with rags stuffed along the edges, then a tube siphoning water from bins in the cockpit. We had to refill the bins every couple days but not a big deal.

I suggest great caution on that practice; it may have been a factor in my system failure (http://www.cruisersforum.com/forums/...or-114081.html), and, nearly certainly, compressor temperatures likely contributed as well.

The literature and cautions don't say why not, but the implication is that it won't be efficient, or, maybe, work at all. Not mentioned is the heat load it imposes on the compressor...
