• 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 systems deliver a new custom designed approach to energy efficient marine refrigeration.


    The ColdEh system adjusts itself for changes and extremes in ambient temperatures. Unlike other air-cooled systems our ColdEh system will not lose efficiency as temperatures rise. The system runs smoothly and silently, always at peak efficiency.


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

    Advanced Refrigeration

    Design Technology.

    ColdEh air-cooled system design eliminates problems like blocked capillary tubes, corroded aluminum components, and water-cooling that guzzles energy and demands maintenance. The ColdEh system uses a much more sophisticated method of controlling refrigerant flow which allows our air cooled system to achieve outstanding efficiency , stability and reliability

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

    Then we built the best system possible - by matching the best quality and maximum efficiency components together.

    We keep it simple,

    and we tested it for durability under extreme conditions, focused on corrosion-resistance and made sure it was compact.

    The result?

    A cost-effective marine refrigeration system that is dependable, energy efficient and easy to install.

    Smarter Cold.

    ColdEh automatically adjusts its cooling capability according to the compartment's load: how warm the food is, how much there is, and how often you open the box.

    Your system delivers consistent refrigeration and freezing temperatures without the use of electronics that can fail.

    The system's core components are made from pure copper for the highest thermal conductivity and fastest cool down.

    That means you can simply count on the system to keep food and drinks as cold as you want them to be (more ice anyone?).

    The result?

    Your ColdEh system is extremely efficient with low power draw.

    That saves energy , reduces fuel consumption and maintenance on your generator and engine also reduces the number of solar panels needed over head.

    It is the ultimate in affordable luxury.

    And you enjoy more of the quiet time that you deserve.

  • 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 the rate at which the ColdEh refrigeration system exchanges heat with its surroundings also increases. The high-efficiency copper components in combination with the Thermostatic Expansion Valve yields consistent performance over varying ambient temperature changes and load conditions , using minimal energy to maintain a 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 our systems are pre-charged with R134A refrigerant which has been in long-standing use in mobile applications . You just have to join the couplers together , plug in the controller and supply the unit with 12V or 24Vdc and you are ready to go.
