Reviewing refrigeration systems that aren't an arm and leg. Someone mentioned Sea Frost.

Looking for any opinions.

Thanks,
GL

WineThief-

It would help if you gave a bit more information regarding what kind of refrigeration system you're looking for as well as the specifics of the boat and engine you're looking to install them on. More information, rather than less will get you better answers.

Are you looking for a 12 VDC based system, an engine powered system or a 110 VAC system?

Are you looking for an integrated unit, or one that you can install in an existing icebox?

Are you looking for a water cooled or air cooled unit?

I would also recommend you read the POST in my signature, since it would probably help you.

winetheif...I had a big seafrost myself and also did a couple of installations on basic ones. I think they make a very good product and are most helpful in designing something and working with you if your application is a bit funky.
They are not the very cheapest...but they do have good basic models.
As the Dawg says...more about what you want to do...how big a box...how much room for the install...full time or part time use...cruising waters etc. would be useful in making a recommendation.

In my experience stay away from engine driven compressor versions, they give too much trouble, use a DC system based around the Danfoss compressor and then focus on building a DC system to support the fridge usage requirements

Just curious, what is wrong with the existing Glacier Bay system?

You have multiple boxes? Then you ain't getting a cheap system.
Suggest the BD/XP with water cooled option and plates is gonna be good for a two box system....unless you have a REALLY big battery bank (like 800+ amp hours). Then you might consider the 1/2 horsepower model that only runs a couple of hours a day...but draws 40 amps. Works great...but expensive.

Might be better off with two smaller units, rather than a single larger unit. That way, if one system fails, you'll still have some refrigeration. Might be a bit more complicated and a bit more expensive... but the redundancy might be worth it. You'd also be able to use one as a freezer and one as a refrigerator more easily by having separate units.

I am replacing a very old Glacier Bay unit, circa 1985, which I have already dropped about $2300 on. I think it is time to start afresh.

Since sending out this thread I have been in contact with two marine refrigeration companyies who both mentioned Grunert and Sea Frost, as well as, and Vitrifrigo brands. I have been quoted about $3500-$4000 installed which sounds reasonable to me.

Water cooled

I assume you are sticking with a water cooled system. For water cooled, the Isotherm self pumping solution looked interesting to me. It does not depend on a pump to circulate water. They claim the movement of the water in throughull allows for fresh water to continually hit the condenser coil. I ended up air cooled so I don't really know how well they work. One other thing is that you may want two separate compressors, one for freezer and one for fridge, so you can size them independently.

I installed my on air cooled, and the price was $1K for the unit, so two compressors, two evaporators (or a cold plate) for $3500 installs sounds not unreasonable. :)

Option #3 do away with refrigeration all together, I read an article in This old Boat last issue where a live aboard family did just that. Aside from changing their eating habits a bit about the only food that they could not keep for weeks at a time or longer were leftovers and fresh meats. So it can (pud intended) be done, not saying I would do it but the option is there. It surely simplifies boat maintenance.
