The Frigomatic keel cooled system is simply the most efficient, reliable and quietest system on the market.

The keel cooled system uses an external heat exchanger bonded through the hull below the water line as the condenser. The keel cooled system is highly efficent using water which is 20x better at conducting heat than air with the added advantage that the refrigerant is cooled by the sea water without the need for a water pump. Ideal for Mediterranean and tropical installations, favoured by grp and steel construction boats. 

Key Features:

• Extremely compact dimensions
• No ventilation required
• Supplied as standard with a speed regulator board
• Able to run on either 12 volts or 24 Volts DC
• Uses R134a refrigerant pre-charged with Frigoboat self-sealing couplings
• Suitable for fridges up to 340 (12.36 cu. ft.) litres and freezers up to 100 (2.82 cu. ft.) litres

Direct Replacement for

• Can replace any condensing set with Frigoboat couplings of the correct capacity
• Can be used on non Frigoboat systems if the refrigeration engineer brazes the connections
