How Do APU’s Work?APU APU
With gas prices skyrocketing you may have noticed a significant increase in your
monthly bills both personally and in your fleet. It is no surprise that the high gas prices have put
a strain on truck drivers. Luckily, APUs act as a secondary energy source for semi-trucks. This
secondary energy source allows for the heating and cooling of the interior of the truck cab. In
fact, anti-idling laws have even made it illegal for trucks to sit idling. This would mean that a
truck driver would be forced to turn off all power to their cab and be without heat, air, or any
electricity. This would mean that truck drivers could not survive out on the road – at least not
within their own cabs. This would increase hotel stays and overall expenses for fleet
management to unmanageable levels.
APUs can be powered by a few different sources. First, an APU for sale can be powered
by electricity. These APUs work by operating through cell batteries. They can vary by the size of
the vehicle and how often they need to be changed really varies dependent upon how often
the APU is used. Electric APUs require little to no annual maintenance. Auxiliary power units
can also be powered by combustion provided that fuel is available. This type of APU does
require annual maintenance. A diesel powered APU for sale can last a significant distance but
does require fuel. However, you will get more out of the diesel powered engine than what you
put into it.
Of course the biggest advantage to consider with an APU is the environmental benefits.
APUs help to save the planet by reducing emissions into the environment. Idling for even a
short period of time releases harmful emission into the air that we all breathe.
