Bid To Use New Reefer Container Technology To Reduce Shipping Pollution

Trials for Carbon Dioxide Based Refrigeration System are Ongoing
Shipping News Feature

WORLDWIDE – Carrier is a name very familiar to anyone in freight, often without them realising where they noticed it. The company’s name appears on the front of countless refrigerated trailers and their products are widely used throughout the shipping industry and Carrier Transicold, part of the Carrier Corporation, supply units which cool refrigerated trucks, trailers and reefer containers alike.

Unfortunately the range of ozone depleting chemicals which have traditionally been used by all refrigeration and air conditioning manufacturers has led to well documented disposal problems in the past and Carrier have been searching for a solution which will both work to a high standard and restore environmental credibility to the industry.

This year will see full field trials for the group’s NaturaLINE™ system which has been undergoing tests during 2010 by German shipping line Hapag-Lloyd which the container carrier says proved satisfactory. Under the system boxes are cooled using the world’s first natural refrigerant technology for container refrigeration incorporating carbon dioxide (CO2) in place of conventional synthetic hydrofluorocarbon refrigerants, which have higher global warming potential (GWP). The system is being engineered to deliver efficiencies currently only achieved by Carrier’s best-in-class performer, the PrimeLINE™ unit.

The natural refrigerant CO2, also known as R-744, is non-ozone depleting with a global warming potential (GWP) of only one, compared to conventional container system refrigerants R-134a and R-404a that have GWP's of 1320 and 3260, respectively. The use of CO2 adds no new environmental risk in the event of a leak. John Mandyck, Carrier vice president, Sustainability & Environmental Strategies commented:

“NaturaLINE technology is a revolutionary breakthrough for the marine container refrigeration market and advances Carrier’s natural leadership in environmental technologies. It also demonstrates how technological innovation can reduce the impact on climate change, continuing Carrier's long-standing commitment to providing sustainable solutions.”

At a time when many supply chain and logistics providers are competing to demonstrate their commitment to reducing the freight industry’s environmental footprint, this new initiative is yet another indication that companies involved with modern methods of shipping cargo are prepared to invest in desirable alternatives to the accepted norm.
