Reefers need to be able to keep freight at a specified temperature, but there is more than one way to achieve thermal efficiency.

SAN ANTONIO — Food transportation will become increasingly complex under the Food Safety Modernization Act, making it more important than ever for refrigerated carriers to closely track their freight and tightly control their operations, said Tom McLeod, CEO of McLeod Software.

Tougher regulations, more carriers carrying more products and new consumer preferences drove the order boom for refrigerated trailers the past two years. They remain catalysts as the up cycle for these trailers continues, experts said.

Thermo King said it has developed a solar panel option for trucks, designed to provide an alternative power source for refrigerated and dry fleets.

Carrier Transcold said it has “set its sights” on increasing the use of natural refrigerant technology with a lower global warming potential for transport applications.

A new final rule from the Environmental Protection Agency gives the manufacturers of refrigerated trailers and their suppliers another three years, through 2019, to develop a new foam-blowing agent that does not incorporate strong greenhouse gases.

A final U.S. Environmental Protection Agency regulation expected this summer has generated significant concerns from suppliers to the refrigerated trucking sector, with the main worry being that a January 2017 rollout date is too soon.
