Actually, I think that all of the Waeco coolers use the compressor-condenser-evaporator type refrigeration cycle. I think that they use Danfoss compressors. The Stirling cycle is very different. A company called Global Cooling probably makes the actual mechanical cooling unit for Coleman. Global Cooling has a good Website at http://www.globalcooling.nl/
I was surprised to read that Coleman recommended that their unit be within 12 degrees of level. I don’t know why.
The Coleman unit is speced at 48 watts or 4 amps at 12 Vdc. It is capable of freezing temperatures but with what looks like about 3/4 inch of insulation the heat flow into the cabinet must be very great. To be competitive on a boat a fixed cabinet needs a lot more insulation than that. I am wondering if there is any way to use the Stirling cycle mechanics in a well insulated cabinet.
