Interesting discussion. Here is a link to a thorough but concise overview of refrig. Capacity and to Dennis' point, a comparison of evaporator vs holding plate types.

Like I said, I bought an Isotherm. I didn't seriously consider the Technautics units because of price. I looked hard at the FrigoBoat and Isotherm units. Both seem to be highly regarded. I just wanted to make the list aware of the Technautics units because they are apparently very good, have excellent technical support and have very low amp draw. Whether or not they're worth the price differential, who knows? I think the bigger decision when considering refrigeration is whether to install a traditional evaporator type unit or a cold plate type unit. There are advantages to each particularly if you turn the system off when you leave the boat for a few days. Touche's Isotherm cold plate unit takes quite a while to cool down but once it does, I think it works very well. We sometimes give it some help by throwing a bag of ice in the bottom of the box. It's been holding temps of 37-38F easily. If you want a quick cool down day sail type system perhaps an evaporator unit is better. My perception is that they cool the box quicker. Dennis C.
