Miller Electric Mfg. Co.'s updated EnPak integrates with a truck's fuel supply and battery so the vehicle can be turned off and still provide power to work tools. The anti-idling system consists of a 60 cfm air compressor, 20 gpm Eaton hydraulic pump, 6,000-watt generator, and a 2,400-watt EnVerter powered by a 24.8 horsepower, Tier IV Final compliant Kubota diesel engine. Technical improvements have added 50 percent more air capacity compared to the earlier EnPak. The EnPak's diesel engine comes with an auto start-stop system and uses 30 percent less fuel than a work truck engine.
The compression capacity of the GoFlo CNG-80 compressor makes it cost-effective for smaller fleets of compressed natural gas (CNG) vehicles, as well as for the initial deployment of CNG vehicles in larger fleets.
