A POWERHOUSE WITH FIELD TESTED RELIABILITY
The 12.5 BTDBR is a 4 cylinder work horse in the Westerbeke mobile line of diesel generators. Air tuning, a cast iron block, and 1800 rpm mean increased power, longevity and smooth, quiet operation. Each 12.5 BTDBR draws on field tested design experience gained supplying generators to the United States Navy, United States Coast Guard, and all the major U.S. Fire Apparatus Builders.
LIGHTWEIGHT, CONVENIENT & READY TO GO
104.2 amps and only 607 pounds, full instrumentation, optional one button start remote controls and glow plugs for all weather operation make the 12.5 BTDBR ready to go when you need it. And when you need to perform scheduled preventative maintenance easy single side serviceability makes the job a snap.
FULL TORQUE, FULL POWER PTO FOR POWER/RESCUE
The 12.5 BTDBR has the exclusive PTO to drive special options for power and rescue. Use the PTO to power high output DC alternators, or add an electric clutch and drive a compressor to bring air to the scene. Add the XRT® Combi package to the 12.5 BTDBR and you have a combination power rescue package for all your electrical and rescue tool needs.
AUXILIARY POWER SYSTEMS (APU)
Reduce idle times as much as 90%, reduce carbon emissions & regeneration times, while drastically reducing DPF maintenance & fuel costs. Our systems can be custom designed to fit your specific requirements, integrating HVAC units, heavy-duty alternators, and the XRT® Combi to run your recue tools.
The 12.5 BTDBR is a clean machine. The diesel power plant meets all EPA and CARB emission regulations and the generator produces clean stable electricity from a 4 pole backend that has simple regulation.
