Dometic’s CoolBreeze air conditioning system is designed to provide cool relief for boat passengers in open spaces above decks. The high-efficiency system blows chilled air through high-velocity directional jets. CoolBreeze’s two-stage operation is totally automatic. When the temperature rises to the lower set point, the controller activates the blowers to move ambient air. As the temperature rises, the second stage activates the compressor to chill the jetted air. CoolBreeze uses environmentally safe R-417A refrigerant.The system can be installed on boats of all types and sizes. It is available as factory-installed OEM equipment and it can be retrofitted as an aftermarket product.
