ARRO Autogas is a subsidiary of Delta Liquid Energy that focuses on the environmental and cost-effective benefits of propane autogas to power fleet vehicles. We supply propane and propane dispensing equipment to fleets of all sizes including school districts, municipalities, and privately owned transportation companies. 

The ARRO Autogas brand was formed by Delta Liquid Energy in 2008 with the sole purpose of being a focused effort in the autogas market. As the need for more environmentally friendly fuel options grows, ARRO Autogas maintains the primary goal of assisting fleets in “going green” and providing an exceptional propane product coupled with outstanding customer service.


We assist in the procurement of propane powered vehicles and equipment for our customers then customize a refueling program that works best with the needs of the fleet. We offer construction of private infrastructure for the convenience of refueling directly in your fleet’s yard or we can provide access to our 24-hour, seven day a week semi-public accessible refueling network.


Prokees and FuelMaster Units

All ARRO Autogas refueling sites, both private and public, are equipped with FuelMaster propane dispensing equipment.


Access to the propane dispensing equipment is only available through individually assigned keys, called Prokees. This is a two part system; two keys must work together in order to start the flow of propane from the dispenser. Each individual using the propane dispenser must first go through a training session with an ARRO Autogas Service Technician in order to be granted access to the equipment and receive their personal set of Prokees.

Back Office

This system allows for quick, detailed reporting of transactions giving ARRO Autogas customer service representatives the ability to send customized reports to our customers.

Accessibility Convenience

Once an individual receives their set of Prokees, access to all public ARRO Autogas sites will be issued. This will allow the individual to fill their vehicle at most of the ARRO Autogas stations.To view a map of our stations, Click Here. If a Prokee is lost or stolen it will be immediately shut down and no further access to ARRO Autogas refueling sites will be permitted with that key.
