LOUISVILLE, Ky. — Thermo King’s TriPac auxiliary power unit (APU) is now available with an Extreme Arctic Kit, which the company says provides improved start-ups in cold weather.
Thermo King officials pointed out that 90% of APU engine wear and tear occurs during start-up, particularly in cold climates. The new Extreme Arctic Kit features a coolant and oil heater which ensures cold start-ups are no more damaging to the APU’s engine than warm start-ups.
When the TriPac senses a coolant temperature below 30 F, the system automatically starts the APU and engages the coolant and oil heaters. The TriPac engine then circulates the coolant between the engine block and the TriPac, monitoring coolant temperature until it reaches 60 F, Thermo King officials explained at the Mid-America Trucking Show.
The new system is available immediately through Thermo King dealers. Also on the subject of the TriPac, Thermo King officials announced the APU is now available with a diesel particulate filter (DPF) which allows it to comply with California Air Resources Board (CARB) emissions requirements. The new system has not yet received official approval from CARB, but officials expect to receive the green light any day now.
Much like the primary DPF on a truck, the TriPac’s particulate filter will regenerate passively during normal driving hours, the company explained. Thermo King officials say the addition of the DPF will not impact fuel economy or place extra strain on the APU. There are nine different mounting options for the DPF, ensuring it’s compatible with all makes of trucks.
