Dearman’s ‘Generation 2’ zero-emission transport refrigeration system has begun vehicle testing.
The system is powered by a liquid nitrogen Dearman engine, which replaces the standard diesel engine. As a result, Dearman claims the system is zero-emission, producing no harmful NOx or particulates, and it helps to significantly reduce CO2 emissions.
Dearman began testing a Generation 1 transport refrigeration system on a truck in early 2015.
Since then the Dearman engine has been re-designed and it is already proving to be 30 per cent lighter, 30% smaller, and 30% more efficient than its predecessor.
Working with its technology partner Hubbard Products, the entire refrigeration system has also been reconfigured, downsizing a number of components and optimising them to deliver maximum efficiency and higher levels of performance.
Dearman’s Generation 2 system will now be tested with support from HORIBA MIRA, before a commercial, on-road, field trial begins with a UK operator in 2016.
Discussing the development, Michael Ayres, Deputy CEO of Dearman said: “This is another important milestone as we develop our revolutionary clean cold and power technology.
We have always planned to evolve and continuously improve our core Dearman engine, but to achieve such rapid improvements in weight and efficiency is a significant achievement.
We aspire to offer systems which are not only cleaner, but that are also cheaper and perform better than polluting diesel alternatives.
We are another step closer to achieving that goal.”
