VPI Plants for Epoxy Resin Processing
LH Marthinusen (LHM) operates advanced Vacuum Pressure Impregnation (VPI) plants designed for high-performance epoxy resin processing of rotating electrical equipment. Our VPI facilities ensure deep resin penetration, consistent insulation quality, and long-term durability for motors, generators, and critical electrical components.
Vacuum pressure impregnation is a critical process for improving electrical insulation strength, mechanical integrity, moisture resistance, and thermal performance in demanding industrial environments.
VPI Plant Capabilities & Specifications
LH Marthinusen’s VPI plants include multiple tank sizes to accommodate a wide range of component dimensions and epoxy resin systems:
4.0 m Diameter VPI Tank
Configured for Sterling Epoxy Class F resin, this tank supports high-temperature insulation applications, delivering excellent thermal endurance and electrical performance for large rotating equipment.
1.2 m Diameter VPI Tank – Epotrak Epoxy 220
Designed for Epotrak Epoxy 220 resin, providing high dielectric strength, strong mechanical bonding, and reliable insulation for motors and electrical assemblies.
1.2 m Diameter VPI Tank – Thixotropic Epoxy Resin
Optimised for thixotropic epoxy resins, enabling superior gap filling, controlled viscosity, and effective impregnation of complex or densely wound components.
0.9 m Diameter VPI Tank – Standard Epoxy Resin
Suitable for standard epoxy resin systems, supporting a broad range of industrial insulation and refurbishment requirements.
