Default In praise of keel coolers

Does the Frigoboat system pass refrigerant through the keel cooler or
cooling water? Does it use a Danfoss BD50F condensing
unit/compressor?

The refrigerant passes through the keel cooler, which is a bronze block
about
6x3 inches and is the condensor. Hot liquid in, cool liqud out.The liquid
then evaporates on exit from the capillary tube into the evaporator.. The
compressor is a Danfoss. It does one hell of a job. However, I have been
having problems with blockage of the capillary tube. The only solution may
be
a new evaporator.


My evap is Stainless clad (only the freezer side - the wall side is still
bare aluminum (well, painted, but not clad).

I got that because I wanted a faster defrost - and I have a very workable
system involving a heat gun and a spatula.

Replacing the evap in our system would be nearly impossible - it would
require removing the top of the reefer/freezer, the countertop being that
impediment to access, as the evap is larger than the door to the freezer (I
built the box from the outside in, putting the top insulation on after the
installation of the evap). It covers three sides, the only part not
involved is the partition with the spillover fan in it.

I wanted never to repeat any of that construction process :{)) and thus the
SS plate.

Otherwise, Gogarty's description is exactly what we have.

Skip, trucking through the list - the first of three pages is all but
crossed out, now, but I'm STILL waiting for the welder for the bow rollers
and cage...

"Believe me, my young friend, there is *nothing*-absolutely nothing-half so
much worth doing as simply messing, messing-about-in-boats; messing about in
boats-or *with* boats.

In or out of 'em, it doesn't matter. Nothing seems really to matter, that's
the charm of it.

Whether you get away, or whether you don't; whether you arrive at your
destination or whether you reach somewhere else, or whether you never get
anywhere at all, you're always busy, and you never do anything in
particular; and when you've done it there's always something else to do, and
you can do it if you like, but you'd much better not."
