Select Separate fridge or freezer (12 or 24 volt DC) for standard 12 volt or 24 volt DC systems to convert an insulated box to a fridge or freezer.
Select Freezer with spillover fridge (12 or 24 volt DC) if you are looking to create a top opening fridge freezer with two adjacent/joined boxes or one box with a divider. Note: that if the volume of your combined fridge and freezer is too large for a spillover system you will need to produce two separate systems one for the fridge and one for the freezer.
Select Large capacity fridge or freezer (240V systems) for refrigerant systems to update an existing built in fridge or freezer. Note that these are designed to refurbish or upgrade large fridges or freezers to run 240V AC only – NOT DC
