hi all,

i am giving my boats freezer system an overhaul. it consisted of 2 systems, the first had a car airconditioning compressor driven by the generator with 2 cold plates in series. this was in the boat when i purchased it. it worked pretty well and the second a 220vt AC compressor with a flat plate evaporator which has corroded and leaks.

i have managed to score a 2nd hand plate that has 2 coils in it and want to connect the AC system to one coil and the other to the aircond comp which will then connect to one of the old plates in series. the plates are stainless with copper piping.

the new plate is from a fridge system so will have the wrong solution in it. the old one although it worked ok i would like to get the right solution in it as well.

so my guestion is, does anyone know what eutectic solution would be the right one? i would like to have a temp of -15c in the box or lower if possible.

any help would be greatly appreciated

thanks
