Company Achievements
Product Range
Transformer Oil Filter Machine
Insulating oil treatment equipment is designed to restore and improve the quality of degraded transformer oil. It uses efficient filtration and degasification combined with advanced high-vacuum and low-temperature technology to effectively remove moisture, gases, and impurities from the oil.
- Imported Pumps and High-quality Filters
- Digital Temperature monitoring and controlling
- Single to three stage Degassing chambers
Vacuum Pressure Impregnation Plant
A Vacuum Impregnation Plant is used to impregnate electrical components such as transformer windings, coils, and motors with insulating varnish or resin under vacuum conditions. The process removes air and moisture, ensuring deep penetration, improved insulation strength, reliability, and longer equipment life.
- Deep resin penetration into insulation
- Strong and uniform impregnation quality
- Vacuum and pressure process cycles
Vacuum Drying Plants
Vacuum Drying Plants are used for drying transformer paper-insulated windings, and they are also used for filling insulating oil under vacuum. The vacuum drying technique is well known for removing moisture from the deep cavities of winding insulation paper.
- Power Transformers
- Distribution Transformers
- CT & PT Drying
Heating Oven
Industrial ovens are heating chambers, used for a variety of industrial applications on components or part of products or the final products itself. Industrial ovens can be used for large or small volume applications, in batches or continuously with a conveyor line, and a variety of temperature ranges, sizes and configurations.
- Annealing
- Curing
- Bonding Finish
- Baking
Casting Metal Impregnation Plant
A Casting/Metal Impregnation Plant is designed to seal micro-porosities in cast metal components using vacuum and pressure techniques. The process ensures leak-proof, pressure-resistant, and durable castings. It is widely used in automotive, hydraulics, pneumatics, and die-casting industries to prevent fluid or gas leakage under pressure.
- Reduces rejection rates by up to 95%.
- Increases pressure holding capacity of castings by 100%
- Reduces downtime caused by leak failures
- Improves overall productivity and profitability.
Vacuum Pressure Impregnation Plant
Vacuum Pressure Impregnation (VPI) is a process by which a fully wound electric apparatus stator or rotor is completely submerged in a Resin/Varnish. Through a combination of dry and wet vacuum and pressure cycles, the resin is assimilated throughout the insulation system. Once thermally processed, the impregnated windings become a monolithic and homogenous structure.
- Improved electric motor efficiency
- Higher Dielectric Strength
- Increased Mechanical Strength
- Reduced probability of motor failure
