The Harrison Truck Centers Severe-Duty Glider Kit for the Freightliner 122SD makes use of a Fueled By Flare dual fuel system designed by American Power Group. The kit was designed and assembled by Harrison for oil and gas, mining, logging, and over-sized load trucking applications.

Harrison selected APG’s Turbocharged Natural Gas Dual Fuel System for its dual fuel heavy- and severe-duty glider kit product line. The truck is designed to meet the needs of specific uses in the field where companies want power and efficiency and need to meet environmental compliance standards.The Freightliner glider kits are available in day cab or sleeper units.

The APG Fueled By Flair dual fuel system can use wellhead gas, conditioned in the field to power its vehicles. The wellhead gas is filtered and conditioned to harvest the methane propane and butane contained in what was considered waste gas by exploration and production companies, according to APG.

“Over 70% of APG’s dual fuel stationary oil rig conversions are operating on conditioned wellhead gas,” said Lyle Jensen, CEO of APG. “We also have our first drilling rig operating successfully on high-BTU conditioned wellhead/flared gas in the Bakken region of North Dakota, an area that is facing significant penalties and restrictions associated with the flaring of their wellhead gas.”

APG believes that the ability to use gas conditioned in the field will have a large market in the heavy-duty trucks that support the oil and gas exploration industry. The company estimates that customers can save 25-35% in fuel costs compared to diesel fuel. APG currently has a severe-duty dual fuel glider truck in the Bakkens.

The dual fuel system works with several OEM engine families, including the Detroit DD15 and DD13 and the Mack/Volvo D13. APG recently recieved EPA approval on all Detroit engine families, including engines from 2009/2010 model years and newer. 

“The economic and environmental benefits of converting this previously considered “waste” gas into usable fuel is one of the most compelling environmental case studies of our time and we believe APG’s Dual Fuel technology will become a major consumer and sustainability solution for operators in this area,” said Jensen.
