Frigoboat's aluminum evaporators are available in three styles:

Bin (B) - a pre-bent plate for installing up-right in a single box to offer a small freezer section in your ice box. No lid is necessary.

Horizontal (H) - a pre-bent plate that comes with a lid, to be mounted horizontally in a single box to offer a small freezer section in your ice box.

Flat (F) - these plates are designed to be bent to fit the sides of your box's walls for an all-refrigerator or all-freezer ice box. Bending instructions and 5/8" stand-offs are included.

Choose the style you want and then the correct size evaporator plate for whether you want a refrigerator or freezer box.

For a spillover system, double the freezer space cubic foot, add the refrigerator space cubic foot and treat the whole box like a refrigerator when selecting the correct size evaporator.

The cubic foot of your box need not be an exact number (L" x W" x D"/1728 = **cu.ft.). Keep in mind the quality of your insulation. If you are unsure, favor a larger plate.
