CD30 Ketch - Refrigeration

[Ed and Pat Carlson]

We are considering installing refrigeration on our CD30 Ketch. If you have it or have done it, we'd like to know what kind of equipment you found works best; what are the power requirements; where did you find the space for the compressor & related equipment? Any drawbacks? Thanx.

We installed ISOTHERM sold by a Swedish company in Seattle. It is a 12 volt cold plate and works like a charm here in Florida. The cold plate was installed in the existing box and the compressor was put on a newly constructed shelf just aft of the batteries under the port seat in the cockpit. We only drilled one hole about an inch in diameter to connect the compressor to the cold plate.

It is a much more efficient system than ADLER-BARBOUR.

It works for us in the summer and makes no noise at night at anchor.

Good Luck...... marv Birdt CD 30 #356....cutter rig

We had the Alder Barbour system in a CD 27 in a similar configuration, compressor aft. It worked fine but be watchful of your power drain. We found that under prolonged sail, the batteries didn't hold up long to the drain from the refrigeration. We ended up just using it when under power or at dockside. We do have a single solar panel that makes up for our underway power and it couldn't keep up with the refrigeration. Just something to consider.

Marv,

I'd be interested in knowing more about your Isotherm unit. Who in Seattle sells it (this is where we live)? Does it allow you to make ice? What is the cycle frequency? Power consumption? Did you add insulation to the box; and if yes, how did you go about it?

I had posted a query about refridgeration a few weeks ago, but it slipped throught the "response" crack.

Thanks in advance!

The company is SCANMAR....206-285-3675 talk to Karl.
They sell a unit that makes ice. Once it cools the box the cycle rate is every few hours. The unit has two levels of cold..one when the engine in on the other when its off. While cruising you must cool it down for an hour in the morning and an hour in the evening. My house battery takes care of the overnight low power operation. I have a portable YAMAHA generator so I don't have to run the engine. The normal temp in the fridge is about 47 degrees F. We did not add any insulation to the box. Given the temp range in your part of the country this should make an ideal solution. It is water cooled and the pump is very quiet. I dealt with Karl long distance and found him to be a first class hombre. The only hole I drilled was to get the connection made from the compressor to the cold plate. I draw water from my head intake and exhaust it out the bilge hole. It is a slick unit. Hope this helps......Marv
