Miller EnPak

The Miller EnPak is a revolutionary, fully integrated power system for work trucks. EnPak combines a rotary-screw air compressor, hydraulic pump, generator and a 24.8 HP, Tier IV Final diesel engine in a single unit and is fully functional with the truck turned off.

Up to 30% Fuel Savings

The exclusive EnPak design reduces fuel use for significant cost savings while delivering the performance that users demand, resulting in maximum productivity. The load-management system monitors accessory requirements and precisely adjusts the engine's speed to match demand, delivering only the amount of power required and minimizing fuel used. Auto start/stop technology shuts off the engine when no accessory loads are detected, increasing fuel savings as well as reducing job site noise and exhaust emissions. When a load is applied, the engine automatically starts up quickly. EnVerter™ technology delivers up to 2,400 watts of continuous 120 V, 60 Hz, pure sine wave power at low engine speeds, providing power for many tools and lights while reducing fuel consumption and decreasing job site noise.


Up to 50% Less Idle Time and 36% Fewer Engine Hours

Turning off a work truck and turning on EnPak can make a work truck last longer. Using EnPak for jobsite functions instead of the PTO can reduce the truck's engine idle time by up to 50%, extending the life of its drive train.

20 GPM Hydraulic Pump

The Eaton variable-displacement piston hydraulic pump seamlessly integrates fuel-saving strategies with precise, high-performance operation. The result is lower fuel costs and well-regulated hydraulic fluid flow for smooth, reliable and precise crane operation. The low-speed lock option further enhances control, minimizing hydraulic flow for maximum precision in crane operation.

Up to 79% Maintenance Savings

Work truck maintenance can't be ignored, but its frequency can be reduced. Turning off a work truck and turning on EnPak can save owners money in several ways. EnPak has lower preventative maintenance costs, does not require diesel exhaust fluid and has no diesel particulate filter to clean or replace.

60 cfm Air Compressor 

EnPak's rotary-screw air compressor can drive a wide variety of tools. Its high airflow capacity can easily power 1-inch impact wrenches and pneumatic pumps, all while minimizing fuel use.

6,000-Watt Generator 

EnPak's low maintenance generator minimizes downtime with a direct-drive, brushless design, which eliminates the need to replace belts and brushes while producing up to 6,000 watts of continuous 120/240 V, 60 Hz power for high-demand applications, including welders.
