    The Isotherm CUBE 40 is a front opening or top loading fridge or freezer for ultimate flexibility in installation and use. The Isotherm Cruise 40 CUBE is an innovative refrigeration unit can be installed like a traditional front opening Isotherm Cruise line refrigerator or freezer with front opening door or as a top loading box like other Isotherm Built-In units. Boat owners now have the flexibility to use the 40 CUBE as a refrigerator for ice cold beverages cooled to temperatures just above freezing, a normal fridge for food and vegetables, or a deep freezer that will maintain temperatures of zero degrees Fahrenheit.


    • The CUBE 40 is designed to be installed as a front-opening or top-opening refrigerator or freezer
      • The CR 40 CUBIC can be used as a fridge or freezer and installed both as a front opening fridge or freezer (Cruise) and / or as a top opening fridge or freezer (Built-In box)
      • As standard installation the CR 40 CUBIC is an ordinary front opening fridge or freezer
      • By changing position, it can be mounted like a cockpit top opening fridge or freezer as the Isotherm Built-In line products
    • Plastic interior lining is extra rugged and easy to clean
    • Interior light and thermostat is easy to access
    • Remote Mount AC/DC or DC only Danfoss compressors
    • Lids are ready to be customized with countertop materials or with panels for the CUBE 40
      • Change the white panel in the door for your own custom look to match your boat’s décor
      • The 40 CUBE is perfect for all applications
    • Charter boat owners will love the range of temperatures and installation options to provide additional freezer space for outbound trips and ability to turn this versatile freezer into a fridge for ice‐cold beverages for thirsty charter parties
    • Small boat owners will love the value of having a unit that will do it all in one product
    • Pair the CR40 CUBE up with a second unit for the perfect fridge and freezer combo
    • The compressor can be remote‐mounted up to a distance of 4.3 feet away so the entire interior space is open for all uses which will maximize storage volume in a small footprint
    • The 40 CUBE uses an open thermostat +50 ° F to ‐8°F which gives users the flexibility to use the product as either a refrigerator or freezer

    IMPORTANT: When the temperature is turned to the maximum cold position, the thermostat will be in the “run” mode continually (no cycling); this will result in the continuous operation of the compressor

    NOTE: The 40 CUBE is equipped with an aluminum grill and a drip tray for collection of condensation water and a transparent ABS drain hose which can be used but is not necessary to drain any condensation accumulation in the top loading orientation
