Thermo King announced a diesel particulate filter (DPF) for its TriPac hybrid auxiliary power unit (APU). The DPF is designed to meet the California Air Resources Board (CARB) emissions requirements for APUs running in California. The TriPac DPF has been submitted for CARB approval and is expected to be available this spring.

In addition to being designed to meet CARB regulations, the TriPac DPF offers several other features important to drivers and owners, said Thermo King. Regeneration, the process of burning off particulate matter trapped in the filter element, takes place during normal driving hours with no disruption to the driver during rest periods. According to the company, the TriPac DPF won't reduce fuel economy and places no extra strain on the APU. The filter also reduces engine noise.

Thermo King also announced the Extreme Arctic Kit for the TriPac, which includes both a coolant and oil heater. When the TriPac system senses a coolant temperature below 300 deg. F, the system automatically starts the TriPac engine and engages the coolant and oil heaters. The TriPac engine then circulates the coolant between the engine block and the TriPac continuously monitoring the coolant temperature until it reaches 600 deg. F.

With the Extreme Arctic Kit, the TriPac not only keeps the driver comfortable in the coldest of environments, it ensures the tractor starts easily every time with minimal wear and tear, according to Thermo King.

Thermo King director of marketing Craig Fisher said that 2008 will see the release of “next generation” trailer and truck reefer units, as well as the new OptiSet Plus system and the new EMS (Environmental Management System) for trailers. He said OptiSet Plus will allow a truck driver to select from 500 different cargo profiles, plus custom profiles, to automatically set the optimum temperature for a given freight.

EMS is a filter system that will reduce airborne pathogens inside a trailer by up to 99.9%, said Fisher, and will sanitize all exposed surfaces, making it ideal for hauling food and other perishables.

Thermo King also displayed at the show the SLX reefer unit it recently launched in Europe to gauge customer interest and gather feedback on its new technology. Thermo King said the SLX is designed to provide both a reduced environmental impact and a lower cost of ownership.
