Didion Autoclave - Vacuum Pressure Impregnation (VPI) Autoclaves

Autoclave Systems for Vacuum Pressure Impregnation

Vacuum Pressure Impregnation (VPI) is a technology in which vacuum and pressure are used to assist the penetration of liquids into certain materials or devices. It can be used in a wide range of applications from insulating electrical coil windings to wood treating. It normally produces better product in less time and lower cost. Didion Autoclave designs and fabricates vacuum pressure impregnation (VPI) autoclaves. Didion Autoclave’s VPI systems can be customized to your specific use, whether it be resin impregnation, wood treatment, or any of the many other applications. Didion’s VPI systems are certainly one of the most cost-effective alternatives to conventional dip and bake methods.

Often times, the chemicals that are to be impregnated into the material are quite corrosive. If this is not taken into consideration, the life expectancy of the VPI system autoclave could be shortened drastically. If you need assistance in selecting the best material for your application, Didion Autoclave would be happy to assist you. We have a great depth of experience when it comes to working with a wide variety of alloys, which is a great asset when it comes to the design and fabrication of vacuum pressure impregnation autoclaves.

Our VPI system autoclaves can be configured horizontally or vertically, with vacuum and pressure, vacuum only, or pressure only. Besides the autoclave itself we can provide you with a complete system that can include computerized controls, vacuum pumps, resin tanks, material handling systems, hydraulic opening and closing of door, ect. Of the few vacuum pressure impregnation system manufacturers, Didion Autoclave stands out as a cut above the rest.
