Options for a New Fridge - Tropicool?

I'd seriously look at the compressor options. Thermoelectric is OK but a right bastard on batteries.

 

When sussing for my 930 I went deep and ended up going the compressor way. A smidgen heavier but a huge power useage saving.

 

I got one of the Weaco portable ones and it works magnificently at around 20-24amps a day all up.

 

Which 930?? asks the nosey bastard ;)

Yeah a mate of mine has a Thermoelectric fridge in his 1020 and by the sound of it, it chews the batteries. I would also be a little concerned about where the heat goes because it could end up heating up your cabin space quite quickly. Nice in winter but not so flash in summer. It looks like there are some big fans on the back of those puppies.

I put a Tropicool in my SR26 and it killed the batteries. The current draw is just too high for boats with limited charging ability. I have a 50 litre Isotherm portable fridge. It runs on 12/24/240 volts. I fill it up and run it up at home, take it down to the boat and plug it in nice n cold. At 4 degrees it averages 1 amp current draw. Very good.

For limited charge boats like mine its hard to look past Gas? got a 12v/240v gas fridge in mine, and it kept stuff cold cold all christmas on less than a 4.5kg bottle of lpg.

I have run my fridge just using a 25W solar panel and a motorbike battery. Went sweet as for over the week it was in use and I have no reason to think it wouldn't have kept going.

My boat has an Isotherm fridge/freezer compressor driven, works a treat and does not seem to use much electricity. It will freeze if run long enough, not as quick as a compressor driven of the main engine though.

anything using a danfoss bd35 or bd50 compressor is what you're after

 

OK, I'm not disputing this statement in any way, but just wondering why you said that L4? What makes the danfoss bd35 or bd40 compressors the ones to have? Are they more efficient, quieter, smaller??? And who uses danfoss compressors in their products?

with the exception of novacool and perhaps one or 2 others using the swing type compressors pretty near every other manufacturer uses the BD series danfoss, the earlier (pre r134a) series of danfoss with a seperate mounting electronics module were a right horror show however the latter ones have stood the test of time rather well, it is worth noting though, that to watercool these systems you'll need to run a diaphragn pump which are not rated for constant cycling and also that the electronic module attached to the compressor does require aircooling and that although these compressors will take 12 or 24 volt as standard input the fan/pump outlet is fixed at 12volt

Thanks for the good advice. It's an 830 - Revolution Blues, sorry to disappoint :wink:

:lol: :lol: Leave it in the rain, it may swell.

 

Damn good and cheap R930 just gone on the market.... for less than rig and sails alone replacement cost. And the rig and damn near all the sails are brand new.
