    The Isotherm 2505 Magnum compact build-in refrigerator or freezer system is cooled by a self-priming raw water pump mounted on the compressor plate. Magnum systems are specially designed for vessels with exceptionally high heat removal requirements such as vessels with large refrigerator or freezer volumes or vessels sailing in tropical waters.


    • Special dual purpose thermostat can set the unit to either refrigerator temperature ranges or to freezer temperature ranges
    • Danfoss compressor
    • High efficiency
    • Constructed of corrosion resistant materials
    • The water cooled system does not vent warm air into the cabin keeping the temperature cooler inside of the boat
    • Water cooled by self-priming raw water pump
      • The integrated seawater pump pulls water through a heat exchanger to increase cooling efficiency
      • Ensures high performance for tropical applications
      • The condenser senses the temperature and controls the output of the variable speed pump accordingly
      • The heat exchanger is manufactured from a corrosion-resistant copper-nickel alloy and fitted with a zinc anode
    • Easy installation thanks to pre-charged system, "click-on" bracket and quick-connect refrigerant lines
