Frigoboat, known world-wide for its fine, quality construction and dependable service has been family owned and operated for almost 50 years.

Put together a system so it is exactly what you want, to fit the size space you have on your boat or RV by choosing a component from the categories below:

Compressor/Condensers: choose water-cooled, air-cooled, or keel-cooled (BD35 for smaller boxes, BD50 for larger boxes and freezers)

Evaporators: bin-shaped without a door for vertical installations; bin-shaped with a door for horizontal installations; or flat-shaped for all refrigerator or all freezer boxes to bend around the sides of your ice box.

Thermostats: select either a simple mechanical thermostat that attaches to the evaporator or a digital thermostat that is also a thermometer that measures the temperature of the air in your box. Both act as the on-off switch for our compressor based on the set point.

Refrigeration Accessories: Those spare parts, or upgrades to make your system hummm.

Cabinets & Drawers: Gorgeous, high-grade, well built, front opening cabinets or double-drawer units, stainless steel inside and out (no plastic linings!). Just add the compressor/condensor of your choice and you're set.
