The following excerpt is from Trucking Info Magazine:
“Through the years, reducing exhaust emissions to meet federal and California limits for any kind of vehicle has cost billions of dollars and added complexity for owners. Will it be the same for operators of transport refrigeration units, which must meet Tier 4 Final emissions limits this January?
The answer will be yes for higher purchasing expense (how much higher, the reefer manufacturers aren’t publicly saying), but the diesel engines on reefer units will avoid exhaust aftertreatment – and other design advancements will mean significantly better fuel economy.
Carrier Transicold and Thermo King representatives delivered this mostly good news during the recent annual meeting of the Truckload Carriers Association’s Refrigerated Division in Idaho. They said they won’t have to use diesel particulate filters or urea (diesel exhaust fluid) injection, two heavy and costly items used on trucks and road tractors since 2007 and 2010, respectively. “
