M&S latest to trial Dearman fridge unit

UK: Marks & Spencer is the latest retailer to trial transport refrigeration powered by Dearman’s liquid nitrogen-powered engine.

M&S will lease a dual compartment Dearman Hubbard TRU on a refrigerated semi-trailer to be operated out of its Hemel Hempstead depot. The retailer seeks to quantify the costs and environmental benefits of Dearman’s technology before a nationwide roll-out.

The Dearman technology replaces diesel-powered secondary engines used to power transport refrigeration units (TRUs), and has the potential to cut CO2 emissions by up to 95%.

M&S has a strong record with liquid nitrogen TRUs. It led the way with hundreds of Polarstream trailers 20 years ago, and has taken on 15 Frostcruise cryogenic units in the last four years. Last year saw M&S use more than one million litres of liquid nitrogen.

“Dearman’s impressive liquid nitrogen technology has shown the kind of results it can achieve and we are excited to be partnering with them,” said M&S fleet engineer Anthony Whitehouse. “Our latest sustainability plan is ambitious and includes bold new science-based target to further improve the efficiency of our operations. Our chilled delivery trucks have a role to play in that and we believe Dearman’s transport refrigeration unit could help us meet our emissions targets.”

The Dearman Hubbard TRU has recently undergone trials on the European mainland with Unilever and had similar trials with Sainsbury’s in 2016.
