Carrier Transicold is offering its customers a variety of green solutions with its Supra line of truck refrigeration units. The Supra units are equipped with engines certified to the U.S. Environmental Protection Agency's (EPA) Tier 4 emissions standard.
The Tier 4 requirement, which took effect for 2008 model-year engines, requires that particulate matter output be 0.4 grams per kilowatt-hour (g/kwh), a 50-percent decrease when compared to the previous standard. The engines used on Supra units reduce the output an additional 40 percent below the new standard. Depending on the model, they also reduce emissions of combined nitrogen oxides and hydrocarbons by 12 to 17 percent below the Tier 4 requirement.
For trucks driven in California, the Tier 4 Supra units also comply with applicable California Air Resources Board (CARB) requirements for diesel truck refrigeration units. Additionally, Carrier offers a simple engine-swap solution to help companies comply with CARB requirements that older engines be "emission enhanced." The Tier 4 engines are completely backward compatible and can fit into any corresponding older model Supra?Tier 2, Tier 1, or older?without any special modifications. It's a direct swap.
Supra units with the electric standby option can be plugged into an electrical supply at loading docks equipped with power drops, providing yet another compliance strategy, with proper CARB documentation. Using the standby mode, engines can be shut down when parked, eliminating emissions, noise, and fuel consumption.
