Vacuum Pressure Impregnation (VPI) is a method to insulate motor stators and rotors with a varnish that allows the motor to be more powerful, efficient, and durable.  

With its division of Imprex, Godfrey & Wing designs and builds VPI systems tailored to customer specifications, ranging from small floor-mounted systems to two-chamber OEM systems.  

Having over 50 years of design and manufacturing experience has led to hundreds of VPI systems installed around the world, ranging from the United States to Peru, and to Vietnam.
