Isotherm Cruise 100 Litre Fridge Freezer - CR100 ASU 381680

Isotherm Cruise 100 Litre Fridge Freezer with Automatic Start-up System 'ASU' - CR100 ASU 381680

Isotherm Cruise Refrigerators offer innovative, reliable and energy-efficient refrigeration system solutions designed exclusively for sailing yachts and motor cruisers.


The Isotherm Cruise 100 litre cabin style fridge/freezer is small in size but big in design. Featuring a separate 5 litre freezer compartment, built-in fan cooled compressor and safety locking device; the CR100 is designed to last even in the roughest of conditions.


The CR100 ASU model features the patented Isotherm ASU-Automatic Start Up energy management system can dramatically reduce the power drain on the batteries while maintaining constant and stable temperatures.

The ASU system senses when surplus power is available (from the engine alternator, solar panels or wind chargers) and switches the compressor to high speed, quickly freezing the holding plate. The ASU system can reduce the battery power consumption by up to 50% or more compared to a similar system without the ASU system.


The 316 stainless steel holding plates contain a safe solution that freezes at -15, storing cooling energy when surplus electrical power is available. The hermetically sealed compressor is the same type used in millions of domestic refrigerators and requires no maintenance.


Installation is quick and easy with quick-connect fittings. The holding plate can be mounted up to 10 feet away. Water-cooled systems have a corrosion resistant copper-nickel condenser/heat exchanger with a reliable, self-priming cooling water pump. Cooling water can be drawn from either a sea-cock or circulated from the boatäó»s freshwater tanks.


Advantages of the ASU System
  • Uses the least amount of battery power.
  • Effective with solar and wind charging systems.
  • Excellent temperature stability and control.
  • Very quiet operation, especially in low speed.
