Mabru RadAir 12,000 BTU 12V DC Rooftop Marine Air Conditioner

Run air conditioning from your battery bank with no below-deck space required. The Mabru RadAir is a patented, self-contained 12,000 BTU marine air conditioner that runs directly on 12V DC and mounts on the cabin top or hardtop inside a sealed dome that looks like a radar. It is a strong fit for boats that lack locker space for a conventional self-contained unit, and for owners who want to cool and heat at anchor without starting a generator.

Key Features

• 12,000 BTU cooling capacity with reverse-cycle heating
• Runs directly on 12V DC; no inverter or generator needed
• Fully enclosed rooftop dome with a hermetic seal
• Copper antimicrobial evaporator coil and large-diameter copper refrigerant tubing
• B30 cupronickel condensing coil for long life in salt water
• 350 GPH 12V raw water pump included
• Digital touch control display
• High static pressure blowers and airflow safety sensors
• Composite mounting base

Installation Notes

• The raw water pump is not self-priming. Mount it level with or above the sea strainer and at least 1 ft below the waterline.
• The display is not waterproof. Mount it in a protected interior location.
• The unit drain pan must be bonded to the vessel's ground.
• A 12V DC unit of this size draws significant current. Battery bank capacity, charging sources and cable sizing should be engineered for the load before purchase.
