The Best Solution to Engine Idling

With a Dynasys auxiliary power unit (APU), drivers can maintain in-cab comfort without the noise, vibration and expense of idling. Operating costs are reduced. And compliance with anti-idling laws is achieved as an added bonus.

Externally mounted on the truck rail, Dynasys is protected in its own weatherproof enclosure and operates using the truck’s fuel supply. This compact, diesel-electric system provides dependable comfort for the driver during downtimes, reduces emissions, and dramatically lowers fuel costs during idling. An optional shore power feature also allows the driver to power the truck’s HVAC from any 110v outlet to work independently from the APU.

 In most cases, this anti-idling solution results in monthly fuel savings greater than a monthly finance payment. So it’s immediately cash flow positive, and immediately contributes to an improved bottom line. Use our convenient Savings Calculator to see how much a Dynasys APU can save you.
