Ardoin, you didn't mention the size of your boxes nor whether you are now with evaporator or cold plates. I guess what you're replacing is a unit with two evaporator plates in the freezer area with a blow-hole into the refer?
The Danfloss used in the "super cold machine" is purported to be appropriate for up to 12 cu ft. Downside is that if one machine is running both compartments, expect a 80% running time at around 40 watts, or roughly around 77 amps per 24 hr period.
Water cooled vs. air cooled is a big question. With air cooled, expect warmer interiors. If like me you're in 100 + degree outside temperature and 85 degree water, heat in the cabin can make a difference in both comfort and the unit's efficiency. Although, for those chilly mornings, a little heat is welcome.
I'm really happy with my cold plates with an engine compressor. It brings the freezer down to 17 degrees in about 45 minutes, and holds a temperature below 32 for about two days.
Just checking in.
Where ya'll keep'n the wimmin 'round here?
