PACKAGED CONDENSING UNITS DESIGNED FOR USE IN MARINE REFRIGERATION AND FREEZER SYSTEMS
Until now, there weren’t a lot of options for marine refrigeration condensing units. Most units on the market are very limited in options for size, fittings, refrigerant, and even brands. For decades consumers have gotten by making the best of the options available.
Those days are over. Introducing POLAR CUBE™ and POLAR CUBE II™, the first adaptable packaged condensing unit available in the size, capacity, voltage, fitting configuration and refrigerant you need.
Refitting an older condensing unit? POLAR CUBE™ is a direct drop-in replacement. The fittings are compatible with most other manufacturer’s units and all connections are in the same orientation. This makes switching to POLAR CUBE™ very easy.
POLAR CUBE II™ debuted at IBEX 2023 and is the only packaged condensing unit with internal solenoid valves. This makes the unit capable of running two separate refrigerated compartments off one condensing unit without having to configure additional external components.

PRODUCT INFORMATION
POLAR CUBE™ and POLAR CUBE II™ solve all the issues found in other packaged condensing units on the market. Most notably, they are easy to service. This compact packaged condensing unit allows marine refrigeration service technicians to replace parts when needed without having to disassemble the entire unit. By removing the cover, all components can be easily checked and/or replaced.
POLAR CUBE™ and POLAR CUBE II™ are compact packaged condensing units designed for use in direct expansion refrigeration and freezer units, such as cockpit refrigerators/freezers or fish boxes. Other popular applications include mezzanine or galley refrigerator/freezers. Packaged units are typically placed remotely and are commonly located in the engine room, lazarette, etc.
POLAR CUBE™ and POLAR CUBE II™ enclosures are white powder coated aluminum and can be mounted on a bulkhead or horizontal surface. The removable positioning brackets allow for ease of installation with clear access to mounting holes. The water-cooled unit has 3 mounting options: back, bottom or left.
POLAR CUBE™ and POLAR CUBE II™ is available with 1/4, 1/3, or 1/2 HP compressors in either 115V/60Hz. All units are available with your choice of resealable couplings or brass base valve connections.
POLAR CUBE™ and POLAR CUBE II™ units are available in air/water-cooled. The air/water configuration will ensure that the unit performs efficiently in hot engine rooms, while also allowing full air-cooled operation when cooling water is unavailable.
POLAR CUBE II™ come pre-configured to run to refrigerated compartments on one condensing unit. No additional solenoid valves required.
All units use R134A or R404A refrigerant.
