Years of Sea Duty Bring Unmatched Reliability On-Shore

Proven power with field tested reliability
The 7.5 BTDAR is a small 3 cylinder work horse in the Westerbeke mobile line of diesel generators.  Air tuning, a cast iron block, and 1500 rpm mean increased power, longevity and smooth, quiet operation.  Each 7.5 BTDAR 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, Ready to go operation and Convenient single side service
32.6 amps and only 560 pounds, full instrumentation, optional one button start remote controls and glow plugs for all weather operation make the 6.0 BTDAR 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 options
The 7.5 BTDAR has the exclusive PTO to drive special options for power and rescue.  Use the PTO to power high output DC alternatiors, or add an electric clutch and drive a compressor to bring air to the scene.  Add the XRT Combi package to the 7.5 BTDAR and you have a combination power rescue package for all your electrical and rescue tool needs.

Clean Machines
The 7.5 BTDAR 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 is electronically governed and regulated.
