    ASU – Automatic Start Up

    • Isotherm ASU charges the holding plate while the engine is running
    • This unique system is designed to automatically start the compressor at full speed when the engine is running and plenty of power is available
    • The ASU electronics control the three-phase Danfoss compressor with full-range speed control and achieves a quicker freezing of the holding plate
    • By taking advantage of the surplus energy generated by the alternator when the engine is running, the ASU feature takes advantage of the surplus power when it is available
    • The ASU system is perfect for sailing vessels under typical cruising conditions when boats uses engines leaving and entering anchorages, then sailing all day
    • The ASU system also is perfect for solar panels and takes advantage of their maximum output during the day
    • ASU systems are available in select cabinet refrigerators
    • The patented ASU system has now been available for more than 20 years and has been installed on tens of thousands of boats worldwide
    • The ASU system starts the compressor when the engine is running and extra power is available to freeze the holding plate completely
    • The energy stored in the holding plate acts like an a block of ice which keeps the refrigerator cold for longer periods
    • This keeps the compressor from running, which saves battery power
    • Once the stored cold is completely consumed, the compressor starts to run for short periods at a slower speed to maintain the required temperature in the box
    • The slower speed also acts to save battery power
    • With its unique principle of operation the patented ASU “Automatic Start Up” system Isotherm ASU has an important competitive advantage over traditional refrigerators

    Isotherm has a 5-year limited warranty on all compressors. All other parts are covered by a two-year limited warranty with one-year warranty on labor.
