• The ColdEh Difference.

    Despite all the advances in energy generation technology, many still struggle with the technology used to store fresh and frozen food efficiently without draining precious power resources.


    ColdEh air-cooled systems deliver a new approach

    to energy efficient marine refrigeration.


    ColdEh's unique system adjusts itself to changes and extremes in ambient temperatures.

    Unlike old air-cooled systems your ColdEh system will not lose efficiency as temperatures rise.

    We make it simple to run at peak efficiency all the time.


    Make ColdEh your choice for full-time, recreational and off-grid use.

    Advanced Technology.

    ColdEh air-cooled systems eliminate blocked capillary tubes, corroded aluminum components, and water-cooling.

    The ColdEh system is simple and sophisticated.

    We did our research and identified opportunities to improve marine refrigeration design component by component.

    Then we built the best system possible - uniquely matching quality, efficient components together.

    The result?

    ColdEh is cost-effective and easy to install.

    ColdEh stands up to extreme weather conditions delivering corrosion and hassle-free performance.

    Smarter Cold.

    ColdEh automatically adjusts its cooling capability according to the compartment's load.

    You get easy-to-set consistent refrigeration and freezing temperatures.

    Our secret? ColdEh's core components are made from pure copper

    for the highest thermal conductivity and fastest cool down.

    It is easy to keep food and drinks as cold as you want (more ice anyone?)

    Want a system you can count on year after year?

    ColdEh is built to be reliable.

    Enjoy remarkably quiet performance with such little operating heat that you can install it almost anywhere.

    Let ColdEh take the worry and work out of your refrigeration maintenance and make solar-powered-only simple.

    It is the ultimate in affordable luxury.

  • FAQ

    Frequently asked questions

    How are energy savings calculated*?

    ColdEh calculates estimated energy savings by comparing test system run-time rates and the average rates noted by leading refrigeration system providers. Our rigorous tests have been performed in 70F/21C and 120F/49C ambient environments. The result? 30% energy consumption savings.


    How do changing weather and ambient temperature condition effect energy use?

    As the ambient temperature increases your ColdEh refrigeration system automatically increases the rate it exchanges heat with its surroundings. The unique high-efficiency copper components work with a Thermostatic Expansion Valve to deliver consistent performance even as temperatures soar and your food stuffs load and use increase.

    It takes very little energy to maintain constant compartment temperature.

    The air-cooled condensing unit runs quietly and efficiently, eliminating the power draw experienced

    with auxiliary pumps found in water-cooled refrigeration systems.


    Will I need to charge the system to install it?

    All systems arrive pre-charged with R134A refrigerant which has been in long-standing use in mobile applications . 

    And we have worked to make installation even easier with easy to connect lines and simple wiring.
