About Dynasys™

We are dedicated to manufacturing and distributing energy-efficient auxiliary power systems for the transportation industry that reduce emissions and the magnitude of climate change. We are ISO 9001:2015 certified, and under our previous name of Hodyon, we were a two-time award winner for growth from Inc. magazine, the 59th fastest growing manufacturer in the US and, according to the Austin Business Journal, the 17th fastest growing company in Austin, Texas.

Since APUs offer both economic and environmental benefits, we expect the use of them to continue to grow and produce even greater savings and driver comfort for many years to come.

Our Mission

We strive to provide quality products and services for mobile climate control applications -- products of the highest quality, made with integrity, and serviced with passion, for a superior customer experience.



Dynasys™ APUs are intelligently designed to provide dependable, energy-efficient performance with convenient service intervals that match scheduled truck maintenance. Each unit is backed by a two-year/4000 hour warranty with an option to extend coverage.

Copies of the Dynasys APU limited warranty, optional extended warranty, and registration documents are available for your convenience, and can be obtained by emailing info@dynasysapu.com.
