Our Grunert is not driven directly by the enine, but by an (inefficient) electric motor
via belt drive. From what I gather, Grunert made both kinds in those years. Something using a Danfoss compressor
and about 7 amps really appeals to me when I think about what the presnt rig consumes. Where I get on to thin ice is: once the compressor is installed and the lines run, the easy work is done. Just where do I run the lines to? the existing system lines run to and from something called a "Dean tank" (.is that the cold plates.......Or is it just the container? Or coils? Can't seem to find that out. ) Part of my questions are pecular to B-40's: can I do the work that I will need to do only removing the side panel facing inboard to the cabin
Would love to hear more about your B-40: her name, how long you have sailed her, where you sail, etc. etc.
