Integrated, Self-Contained Air Compressor, Hydraulic Pump and Generator from Miller
Miller Electric Mfg. Co. introduced its new EnPak™ Mechanic Series at the National Truck Equipment Association’s (NTEA) 2009 Work Truck Show in Chicago. Powered by a 27 hp Kubota engine, EnPak eliminates the need for a PTO and integrates seamlessly into its electrical and fuel systems, allowing mechanics to run their tools with the truck’s engine turned off.
EnPak’s variable speed rotary screw air compressor, Miller’s Air Pak™ 40, offers a rated 40 CFM at 100 PSI with a 175 PSI maximum that allows mechanics to use air tools without having to stop working to wait for pressure to build. Its Eaton variable displacement piston hydraulic pump powers a rated 3000 psi at 32 l/min (up to 75 /min maximum) and offers smooth, fast and accurate crane operation. And 6000 W of generator power at 100% duty cycle plus an additional 2400 W of pure sine wave EnVerter™ power at idle is available to run electrical tools including welders, lights and laptops used for equipment diagnostics.
EnPak features the exclusive EnPower™ Technology: real time load monitoring that automatically matches engine speed to the load requirement put on the machine. This offers additional fuel savings as RPMs only ramp up to levels needed to perform the task and then fall back down to idle when finished.
EnPak’s diesel engine shares the truck’s fuel supply; this means mechanics only have one tank to fill. It also uses the truck’s 12 V battery, eliminating the need for a second battery. EnPak even provides 12 V of power and a 60 A charge to the battery to ensure peak battery performance and extended battery life.
EnPak also maximizes truck bed space by housing the generator, air compressor and hydraulic pump in one self-contained unit instead of having multiple machines for each capability. It can be mounted as a sidepack or in the load space and is only 2,5 cm taller and wider than Miller’s Bobcat series of engine-driven welding generators. It does not require a cut-out in one of the truck’s storage compartments for front panel access, as EnPak can be operated completely by remote. And all service components are easily accessible through hatches at the front and top of the machine.
