Rayfrigeration; First Zero Emission Solar Truck Refrigeration Unit


Rayfrigeration, the first zero-emission refrigeration unit thanks to solar energy, is ready for use in freight trucks dedicated to deliveries in urban areas. This has been verified after five months of tests in real working conditions, in which this system has achieved a reduction in emissions of nitrogen oxides (NOX) and carbon dioxide (CO2) of 98% and 86% , respectively.

They are not the only achievements of this innovation, the first of its kind ready for commercial use, after months of examination in a dairy delivery truck in Fresno, California. The system also makes it possible to contain atmospheric pollution by particulate matter by 97%. In addition, another advantage is its ability to reduce operating and maintenance costs by 90% compared to refrigeration units that run on diesel.

Until now, refrigeration systems for trucks incorporated small diesel engines that guaranteed the necessary temperature for the transport of products that require refrigeration. The advance launched by the company eNow radically changes the model by offering the market the first electric unit whose battery obtains the necessary energy in two ways.

The first is through a high capacity backup system that recharges when the system is plugged in overnight. On the other hand, when the truck is running, a system of photovoltaic panels installed on its roof provide the energy necessary for this unit to cool medium-temperature cargoes.

During the testing phase, conducted in midsummer on the streets of California, the 1,800-watt solar system provided more than enough power to maintain temperature during a typical workday, marked by the continuous opening and closing of doors during deliveries.

Rayfrigeration’s performance during the five months of tests on board a Challenge Dairy truck has led this leading brand in dairy products to be planning to replace its entire fleet of distribution trucks, to equip it with these systems.

And, as the promoters of this electric unit for refrigerated trucks explain, the savings for companies that opt ​​for this alternative is significant, since they will no longer have to worry about fuel costs or engine maintenance.

Rayfrigeration is an “important step forward towards reducing emissions that, in addition, guarantees the highest levels of efficiency,” says the president and chief executive officer of eNow, Jeff Flath, who emphasizes that this new unit allows to provide energy “free of emissions for a task as critical as the refrigeration of fresh food ”.

And so it is deduced from the data collected in the testing phase. The emission reduction that Rayfrigeration brings about is truly significant. In four working days with 7’7 hours a day, a conventional refrigeration unit would emit 2,525 pounds of CO2 and 7,162 grams of NOX. This novel system reduces them to 159 in the first case and 1 gram in the second.
