How to make a good eutectic holding plate

Good day all. Time to bring all you great sailing brains together and solve a problem. Mainly how to keep the cold ones cold. I need to make several eutectic holding plates for the replacement freezer system. I am using Danfoss DB50F compressors and would like to know all I can about how to actually build these cold holding monsters, and of coarse making them work properly. Any and all info will be thought about long and hard. What I need is practical hands on advice one the nuts and bolts make it work of eutectic plates. Thanks in advance for the help

More than just the over view needed

Thanks. Yes good site but mostly just overview. What I need is the actual hands on how to make the monsters. Bit more technical details and less general stuff. Thanks in any case. OK guys one of you has done this before so caugh up with the details!

I think you might want to try the site again, perhaps either asking a question on his forum or asking if the topic is addressed in one of his books.

More parts of the puzzle

Thanks for the ideas. I checked both sites and have grabbed a few good ideas from both. I should mention this whole exercise is not based on being cheap... although I am learning how much the big "marine" freezer companies mark up... where we are now it is almost impossible to get spares in without being gaffed solid by the rubber stampaholics and their kin. Bribes, backhanders, and all included things can wind up costing three times before one actually has the bits on board. So, please do keep the ideas flowing. I am sure that this can turn into a very useful thread for a lot of people. I know what I have already learned about Danfoss compressors alone will save a lot of cruising funds for many people. Once this dance is over I want to write up what I have learned and post it for the benifit of sailors everywhere. Now about those holding plates?

Get a hold of Nigel Calders MARINE rEFRIGERATION FOR pLEASURE bOATS. In it he describs in detail all phases of building and more importantly designing a holding plate system. However in my opinion since Danfoss compressors have limited hp, I've always questioned the wisdom of using eutectic plates vs a preformed al evaporator. I know htere's a small efficency improvement, but it may well be offset by the size of the plate as wasted space, whereas if you us oval evaporators you gain a small freezer. I don't know the details of your plan, or the size etc of the box. Good luck. George

Having a look at reality from the end of the world

I would love to get a good book on the subject then I could laze in the bar while I boned up on what to do and how. Problem is

1. Book costs about $50
2. DHL to the end of the world about $100
3. Bribes etc to get it in my hands another $100

Start getting the idea? Oh and I forgot the 3-4 weeks the 5 day DHL takes. In any case thanks for the suggestion.
