RRU was founded in 2005 in Barnesville, Minnesota.

RRU started upfitting (winterizing) generator set enclosures with insulation, motorized dampers and hoods. We also change or add accessories such as circuit breakers, battery chargers, etc.

RRU also designs and builds maintenance platforms for generator sets. We will ship them to you or give you a quote to go to the jobsite and install them.
