Frigibar freezers are constructed from the highest quality marine materials. They are designed to operate in an uncovered salt air environment while maintaining zero degree Fahrenheit. When ordered with our "Dual Control" option they may be used as a freezer or refrigerator. With optional "Frigi-Bank" holdover plates our units require minimum of generator "on-time" to maintain freezing temperatures all day long. When the plates are not required they may be removed from the freezer and stored in any convenient out of the way location.
