The ProMax APU - Powerful Comfort
Why Buy a ProMax APU
When it comes to APU's, comfort and rugged reliability are key, and ProMax APU delivers.
Our engineering team has gone to great lengths to deliver comfort where and when
you need it. The ProMax APU features:
Superior Comfort
- The most powerful APU on the road! ProMax APU produces 33,000 BTU for both heat and
AC.
- More CFM's for whole cab comfort. ProMax APU's 650 cubic feet per minute of air flow
deliver comfort throughout your cab. Heating and cooling capacity is only effective
as the systems' ability to circulate and process the air. The more cubic feet per
minute of circulation, the more comfort.
- Sleeping soundly is engineered right in. Our 3 cylinder Yanmar diesel operates at
a low 2100 rpm's, which produces less vibration and noise. Our patent pending suspension
system further isolates the engine, ensuring undisturbed sleep.
- Our optional Inverter brings creature comforts to your cab. The ProMax APU's optional
inverter delivers power to your cab to allow you to watch a movie, microwave dinner,
or work on your computer. It even provides a shore power hookup for added convenience.
- Diesel powered comfort just keeps on going. Just like your truck, the ProMax APU
is powered by a diesel engine that won't create mysteries when it comes to maintenance.
It shares the same fuel as your truck, so keeping it fueled requires no special consideration.
Unlike battery-powered units, there is no limit to how long it can operate before
requiring you to get back on the road. It is designed to give comfort until you are
ready to go.
Rugged Reliability
At Dunamis, our goal is to make your life easier and hassle-free. The design of the
ProMax APU demonstrates these principles in action:
- 3 cylinder vs. 2 cylinder vs. a battery system. A 2-cylinder motor could power our
system, but higher loads provide lower dependability and a shorter service life.
Batteries lose their ability to hold a charge throughout the night as they age, and
performance is further hampered by cold weather. That's why the ProMax APU is powered
by a 3-cylinder Yanmar diesel engine.
- Analog vs. Digital Controls. Digital electronics provide flashy features, but are
much less reliable. We chose an analog control panel for the ProMax APU which is
durable and provides reliable long-term service.
- Power to get you home. Losing your main engine alternator can strand your truck
and delay your delivery schedule. Equip your truck with a ProMax APU and you'll have
a 200-amp alternator that is powerful enough to get you home without your main engine
alternator. Lose your main a/c compressor or heater? No problem. The ProMax APU was
built to deliver heating and cooling comfort on the road or off. Your ProMax APU
will get you there in comfort.
Modular Installation and Simple Service
- Self-contained stand-alone modular unit attaches directly to the frame of your truck
to minimize vibration while you're trying to sleep and to provide easy access when
service is needed.
- The ProMax APU will not void your truck warranty.
- Maintenance can be done by your diesel mechanic. All components are analog which
makes for easy and durable service. To view the complete service schedule, please
