Newly Enhanced EnPak® Further Improves Productivity and Jobsite Functionality

Work truck solution reduces truck idle time, fuel usage, engine hours and maintenance costs — all leading to costs savings

APPLETON, Wis. (Jan. 9,  2014)  — Miller Electric Mfg. Co. has announced enhancements to its work truck solution EnPak®  — a  60 cfm air compressor, 20 gpm Eaton hydraulic pump, 6000-watt generator and 2400-watt EnVerter™ powered by a 24.8 hp, Tier IV Final compliant Kubota diesel engine. Integrated with the truck’s fuel supply and battery, EnPak allows for full jobsite functionality with the work truck’s engine turned off.

Technical advancements to the load management system along with increased component efficiencies allow EnPak to provide up to 60 cfm (previously 40 cfm). Offering 50 percent more air capacity, EnPak can easily power 1-inch and larger impact wrenches and other pneumatic tools and pumps to support multiple field applications.  Air-on-demand eliminates lag time common with reservoir systems that only engage the compressor after a minimum pressure has been reached.

The exclusive load management system means EnPak maximizes fuel savings by delivering only the amount of power required while allowing for simultaneous operation of the generator, compressor and hydraulics. One mechanic can weld on one side of the truck while another grinds or uses an impact wrench on the other side without any lag in power.

Fuel savings also are realized with the auto start/stop technology, which shuts off the engine when no loads are detected and automatically starts the engine when work needs to be done. The EnVerter power system delivers 2,400 watts of continuous 120 V, 60 Hz, pure sine wave power, allowing the user to operate many jobsite tools at lower engine speeds, which reduces noise levels along with saving fuel.

The diesel engine uses up to 30 percent less fuel than a work truck’s engine and costs much less to maintain. Field testing reveals up to 79 percent in maintenance cost savings at idle compared to a conventional PTO-equipped truck. 

For MIG, TIG and Stick operations as well as arc gouging applications, the Miller Maxstar® 200 STR and Miller Multimatic™ 200 welders — which can be powered off of EnPak’s generator — provide superior arc characteristics for strong, quality welds and come in portable packages that weigh less than 35 pounds.  

“Miller has the right equipment for a truck to get the job done while extending work truck life and reducing maintenance costs and worksite noise,” said Travis Purgett, product manager for Miller Electric Mfg. Co. “Together Miller and EnPak provide a strong value proposition of maximum performance, versatility and cost savings — all reasons we see EnPak in work truck fleets across North America. Operators can feel confident in turning off their truck and turning on their EnPak.”
