Vacuum Pressure Impregnation (VPI) is a process that uses vacuum and pressure to seal porous materials with varnish or resin. The process is used primarily for high-voltage motors and generators to fill gaps in materials to create a void free insulation in various devices. ​   The Vacuum Pressure Impregnation Process AR Engineering specializes in vacuum pressure impregnation, which is more effective than traditional dip-and-bake methods and is better suited to high voltage motors and generators. Our basic vacuum pressure impregnation motor repair process comprises several steps.   PreheatingWe place the equipment in an oven that heats the equipment and allows moisture to evaporate. This helps the resin better penetrate the material.   Vacuum DryingWe remove the equipment from the oven and place it into a vacuum chamber, which removes air and any remaining moisture.   FillingWe fill the chamber with resin, coating the part and filling in all the gaps and pores in the piece of equipment.   Wet VacuumingWe reduce the vacuum levels and hold it for a set period of time.   Pressure/SoakingWe increase pressure within the chamber using dry air, nitrogen, or other gases. This allows for even deeper penetration of the resin.   DrainingWe then vent the pressure, drain the chamber of excess resin, and remove the part.   CuringFinally, the equipment is placed into an oven to cure the resin.   Vacuum Pressure Impregnation Plant Vacuum Pressure Impregnation (VPI) is a process that uses vacuum and pressure to seal porous materials with varnish or resin.

The reduced volume leads to air pockets and gaps, making it more susceptible to damage and wear. The vacuum used in a VPI creates a more solid structure that can withstand:​ Leaks Cracks Corrosion Moisture   VPI also accommodates longer insulation life and greater heat dissipation. Vacuum pressure impregnation is a more cost-effective solution as it extends the lifetime of products while saving energy.​
