Isotherm Cold Plate Refrigeration Kits
Convert small boat refrigerators and freezers to a holding plate design so you can get the best performance on long voyages. This marine refrigeration system use a holding plate, or cold plate, designed to freeze and slowly thaw. It can keep items cool for hours before you need to activate the compressor again, letting you maximize limited electricity.

We carry air-cooled and water-cooled holding plate refrigeration kits to update a fridge, built-in cooler box or another boat storage area. Browse ASU, SP and Magnum cold plate refrigeration systems; depending on the design, they can work in refrigerators up to seven cubic feet and even operate tiny freezers. The compressor works with 12V or 24V power sources and the kits include pre-charged quick connects; water-cooled systems add a self-priming variable speed pump.
