Dearman has begun on-vehicle testing of its latest zero-emission transport refrigeration system.
Powered by a liquid nitrogen engine, Dearman said the system produces no harmful NOx or particulates and significantly reduces CO2 emissions.
The manufacturer first began testing its liquid nitrogen technology at the beginning of this year, but since then has refined the refrigeration system, alongside technology partner Hubbard Products, to be 30% lighter, smaller and more efficient.
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.
Michael Ayres, deputy CEO of Dearman, said: “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.”
In June this year, the company opened the Dearman Technology Centre in Croydon, Surrey, which it said will become a hub of liquid air engine design, engineering, test and development.
