“We’ve significantly improved the cooling capacity, because the faster you can get the trailer temperature pulled down to the required level for the cargo, the faster you can load and get out on the road,” he said.
Mark Watson, global marketing manager for Thermo King, added that demand for multi-temperature capable trailer reefer systems is growing at a much faster rate. For starters, Watson said, there are guidelines under Hazard Analysis Critical Control Points (HACCP) regulations developed by the Food and Drug Administration that demand tighter temperature control for perishable cargo in order to prevent food-born illnesses.
Watson added that grocery and food service companies want more efficient use out of their trailers because they want to divide up trailer capacity now and haul both, and Spectrum allows them to do that.
The Spectrum SB reefer model allows for three temperature controlled zones to be established within the trailer, while the Super II allows for two zones and the DE for one zone. Maintenance intervals on all the Spectrum models has been boosted from 1,500 to 3,000 hours, said Lenz, reducing maintenance costs to customers.
“What our customers have told is us that they want simpler, more efficient products,” said Watson. “With Spectrum, they can deliver several different kinds of perishable with one trailer at better economics in terms of maintenance and pull down costs than before.”
