Dometic Cooling Units are a state-of-the-art technology that is efficient, quiet, and vibration free. They also come with a 1 Year Warranty.
To validate inhibitor 7 function, Dometic has conducted extensive testing. These include laboratory investigations and service life evaluations.
Absorption Refrigeration Technology
Dometic Cooling Units are designed to run on variable energy sources, to be noise and vibration free and to have a long product life. These are important considerations for the mobile comfort niche market where these technologies are used in products such as RV refrigerators, Minibars and medical cold equipment.
Absorption refrigeration systems are based on the principle that heat is extracted from a liquid, and the vapor is liquified to produce cooled refrigerant. The evaporation rate of the refrigerant is dependent on the partial pressure of the vapor above the liquid.
The cooling system in an absorption refrigerator is composed of a boiler, an evaporator and an absorber. In the evaporator the refrigerant is evaporated at a low pressure and temperature. It is then allowed to move into the absorber. This process is repeated until the refrigerant vapor has a saturation point or a slightly sub-cooled state.
Variable Energy Sources
Dometic Cooling Units can be powered from a variety of variable energy sources. For example, Dometic’s RTX 2000 rooftop units can be cooled from solar panels, diesel fuel or a battery.
The use of renewable and low primary fuel consumption energy reduces the CO2 footprint of the cooling system as well as extending the service life. It also ensures that the system operates efficiently in all conditions and provides a high level of customer satisfaction.
In addition to the use of alternative refrigerants, Dometic is engaged in the development of technological solutions that can replace sodium chromate. If these solutions would become available to competitors, they could potentially replicate them and thus weaken the competitive position of Dometic.
Noise and Vibration Free
Whether on land or in the sea, Dometic’s self-contained marine air conditioning systems are designed to perform under the most extreme conditions. The galvanized steel top plate and long copper lines minimize vibration, while a specially engineered R-410A refrigerant minimizes noise.
Dometic’s patented Turbo unit was engineered to harness and maximize the power of R-410A refrigerant, resulting in quieter, more powerful operation with a rust-free drain pan. Moreover, the optional Turbo sound cover reduces noise by up to 50%.
Since 2000, Dometic and co-operation partners have tested a number of inhibitors in absorption cooling units at alkaline temperatures up to 200 degrees Celsius (heat transferring areas). One inhibitor, called “inhibitor 7”, showed promising results for complete cooling units.
A Dometic Cooling Unit is a cost-effective way to provide your motorhome with comfort and convenience. We offer a range of models that deliver 4,000 to 72,000 BTUs of cooling power per hour and are 27 percent more energy efficient than similarly sized units from other manufacturers.
This is because of our absorption refrigeration technology that uses a limited amount of heat to operate without moving parts. These systems can run on electricity, kerosene or gas.
During the absorption process, carbon steel absorbs heat from the atmosphere and transfers it to water inside the evaporator where it is cooled down to a temperature where it can be evaporated. The system can be used to cool and heat a wide variety of applications such as refrigerators, freezers, air conditioning or ventilation fans.
The absorption refrigeration technology also uses sodium chromate as a corrosion inhibitor in two of the Dometic manufacturing plants in Siegen (Germany) and Jaszbereny (Hungary). This inhibits the formation of rust on the cooling system.
