Vacuum Pressure Impregnation Plant

---

Vacuum Pressure Impregnation Plant is a important product of varnishing machine 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. AR Engineering specializes in vacuum pressure impregnation plant, 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. So, Vacuum Pressure Impregnation Plant is a essential part of varnishing machines.

Preheating

We place the equipment in an oven that heats the equipment and allows moisture to evaporate. This helps the resin better penetrate the material.

Vacuum Drying

We remove the equipment from the oven and place it into a vacuum chamber, which removes air and any remaining moisture.

Filling

We fill the chamber with resin, coating the part and filling in all the gaps and pores in the piece of equipment.

Wet Vacuuming

We reduce the vacuum levels and hold it for a set period of time.

Pressure/Soaking

We increase pressure within the chamber using dry air, nitrogen, or other gases. This allows for even deeper penetration of the resin.

Draining

We then vent the pressure, drain the chamber of excess resin, and remove the part.

Curing

Finally, the equipment is placed into an oven to cure the resin.
