Thanks for all the recommendations- the reason I'm looking at Adler Barbour is because they claim 35f with a 15cuft box size with 40% run time and 80f ambient temp.. I haven't found any similar claims from other manufacturers using the BD50 compressor. This box is 12.2 cuft with 4" insulation if I get 40 degrees at 40% run time it will be adequate, if I get 35 degrees at 40% run time I'll be happy.
The water cooled feature is something I would need not because of efficiency, but because any additional heat in the boat has to be moved out with A/C to stay comfortable. I might as well put the heat directly into the water and save the load on the other heat pumps. In my home waters we have more of a fresh/brine mix than an actual full salt water, so growth is less of an issue here than in many places. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Norm of Bandersnatch Sent: Sunday, November 18, 2007 10:11 AM To: [email protected] Subject: Re: [Liveaboard] refrigeration I have used stand-alone, air cooled, units with success. The first was an old RV propane/electric unit. Both the propane and the electric were to heat the "boiler" and thus operate the unit. Although the propane part worked well the electric parts, heater tapes on the boiler, failed before a year was up. The biggest problem was the front opening door leaking cold and the thinness of the insulation making for poor efficiency. Next I had two Engel units, 1.5 cu/ft each, one set to zero the other to 38 deg F. These worked very well, drew 2 amps each when running but also had thin insulation having been designed for vehicle use with unlimited supply of 12 VDC. We now have two Sundanzer units, a freezer and a reefer, 5 cu/ft each, but because of 4.3" of insulation also draw 2 amps when running. We are very happy with these but do admit the may be too big for most boats. The Engel units are built in such a way as to be able to remove the machinery as a whole, opening up the possibility of making your own box with good insulation and installing the Engel machinery in that box. Also I have seen in magazines boxes like the Engel units that appear to have more insulation and plastic rather than steel shells. I recommend not using water cooled units. I have heard of lots of problems due to fouling of the seawater circuit with organisms, plus the additional load of the seawater pump. For satisfactory results no matter how you produce the cold, the box must be top opening with at least four inches of insulation.
