Hubbard tests Dearman 2 engine

dearman-refrigerationUK: Dearman has begun on-vehicle testing of a second generation liquid nitrogen transport refrigeration engine.

Dearman and its technology partner Hubbard Products began testing its liquid nitrogen Dearman engine, which replaces the standard diesel engine, on a transport refrigeration system in early 2015. Since then the Dearman engine has been re-designed to be 30% lighter, 30% smaller and 30% more efficient than its predecessor.

The entire refrigeration system is also said to have 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 independent test house 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.”
