2. Welcome to AR Engineering AR Engineering is a company founded by Mr.ArvindMutalik in 1988, for manufacturing of transformer oil filtration machines. Since then AR Engineering has developed different types of Insulating Oil upgrading systems suitable for in-house and onsite operation.

3. ABOUT US • AR Engineering is a company founded by Mr.ArvindMutalik in 1988, for manufacturing of transformer oil filtration machines. Since then AR Engineering has developed different types of Insulating Oil upgrading systems suitable for in-house and onsite operation. The plants are suitable for Transformer & Capacitor Manufacturers, Transformer Repairers, Transformer Owners, Oil filtration service providers etc. These plants work on low temperature, high vacuum principle. • We also developed Trickle Impregnating Machines for varnishing of electrical machines windings such as armatures, rotors, field coils, stators. These machines are suitable for varnishing of electrical windings in mass production. Auto electrical parts, mixers, fans, electrical motors, Instrument transformers etc. are few to name. • We also manufacture Vacuum Impregnation Plants for big electrical windings and Vacuum Drying Ovens for drying of transformers, capacitors etc. On line transformer oil regeneration plants are under development.

4. OUR PRODUCTS • Trickle Varnishing Machine • Transformer Oil Filtration and Dehydration Plant • Industrial Oil Purification Unit • Vacuum Pressure Impregnation Plant

5. 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 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 ProcessAR 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.

6. Vacuum Pressure Impregnation Plant 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.

7. The Benefits of VPI • In traditional impregnation, varnishes can lose up to 50% of their volume in the curing process. 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.
