Frigoboat K35F Keel-Cooled Marine Refrigeration System 12/24V

The Frigoboat K35F is a premium keel-cooled marine refrigeration system engineered for sailors and long-range cruisers seeking maximum cooling efficiency with minimal power consumption. Utilizing a keel-mounted heat exchanger, the K35F transfers heat directly to surrounding seawater without requiring a circulation pump, reducing electrical demand and improving reliability.

Built around the Secop (formerly Danfoss) BD35 compressor platform, the K35F delivers dependable refrigeration performance for marine refrigerators and freezers while maintaining exceptionally low energy usage. The keel cooler design can provide over 20% greater efficiency compared to conventional air-cooled systems, making it ideal for vessels operating on battery and solar power.

Compatible with multiple evaporator configurations, the K35F can support refrigeration boxes up to 340 liters and freezer compartments up to 110 liters depending on evaporator selection and insulation quality.
