Grunert refrigeration

[telekitr]

We are restoring an older (1984) Passport 40. The current refrig system is a combo of one cold plate hooked into an AC condenser and one cold plate hooked into an engine driven condenser. Since we will be spending most of our time on a hook or sailing and only a minimum at docks, my thought is to replace the current units with a DC driven unit that is powered by battery.....being charged by solar and wind generators. I have an opportunity to pick up an older (1990) Grunert DC belt driven condenser at a pretty good price. I would also like to make use of the very nice and seemingly strong cold plates that appear to be in good condition. Has anyone had experience with this type of system and, are cold plates that are now likely to be in excess of 15 years old, likely to be reliable?
