Dynasys™ Auxiliary Power

With over 26 years serving the transportation industry, we understand how rising fuel costs and mounting operating expenses continue to impact your bottom line. Keeping your fleet running and your drivers productive is key to a healthy, profitable operation. But idling a tractor to power your drivers’ cab during downtime is very expensive and a major contributor to escalating costs and lower earnings.

With a Dynasys APU, you can give your drivers the cabin comfort they deserve, cut your fuel costs associated with idling, and comply with state anti-idling laws all at the same time.  Because your trucks will idle less, you can also reduce wear and tear on engines and components, lower maintenance costs and improve meantime between service calls.
