Tripac APU
Thermo King’s TriPac APU provides cost savings by reducing unnecessary fuel consumption, extending truck engine maintenance intervals and reducing wear on the truck engine.TriPac also allows truck owners to comply with anti-idling laws while the driver rests in comfort.
TriPac uses a fuel-fired heater and Thermo King’s Cycle Sentry start/stop technology to achieve maximum fuel efficiency. In cool climates, the TriPac engine will only operate if battery charging or engine block heating is required. If not, only the fuel-fired heater will operate to warm the cab while consuming minimal fuel.When battery charging and block heat are necessary, TriPac can automatically start to address those needs and then shut down to save fuel.The result of this approach is a system that runs substantially fewer engine hours than competitive models.
The available tractor integration option allows the system to start up automatically when the truck engine is turned off, ensuring a charged truck battery and warm engine block when it comes time to restart the engine.
TriPac now offers a 1,000-hour maintenance interval, allowing maintenance to be performed at the same time as maintenance on the tractor, saving time and eliminating additional downtime for APU maintenance.
Because of the modular component design,TriPac can be installed in a variety of truck models and configurations.The engine assembly, or APU, is mounted on the truck frame rails.The air-conditioning evaporator and fuel-fired heater are installed under the sleeper bunk, the condenser is installed on the rear cab wall, and the control panel is mounted on an interior wall of the sleeper.Ducting for the heat and air conditioning is also flexible. It can be routed directly to the cab or integrated with existing ducting.
A Thermo King two-cylinder diesel engine powers an air conditioning compressor and a 12-volt alternator, both of which are the belt-driven “automotive” style. These components power the air conditioning system, keep the truck batteries charged and provide tractor engine heat.The truck engine block is heated by incorporating the engine coolant systems between TriPac and the truck engine.This approach to engine block heat is very effective because the engines warm each other while running, to ensure easy starting in all climates.The system even incorporates engine coolant temperature sensing.

3.2I have had my Tri-Pac now for 2 years. I can say that it is dependable and I am happy about that. I have had a few minor problems here and there which is to be expected. What I don’t like is that Thermo King charges an arm and a leg when I do need repairs or service. I would probably give it 4 stars if the AC were more powerful. In the summers if the temperatures go any where near the 90s or higher the AC is pretty much useless and that is in my standard size cab.

4.4Well I have to say that this thing runs like a Deere. It has only pooped out on me once. The cooling is not as powerful as many of the other APUs but it runs good so what can I say?
