Equipment for Cast Resin Insulation

Wherever reactive resin systems are processed, this is where our design for preparation, mixing and dosing is implemented. Based on our decades of experience, we have permanently developed and perfected our vacuum systems for cast resin insulation.

To name just a few of our innovations let us introduce the on-demand principle for on-the-fly degassing in our batch equipment and our patented on-the-fly formulation units for a continuous preparation of the desired cast resin system.

Equipment for Oil/Paper Drying and Ipregnation

HEDRICH offers a variety of drying technologies for different applications. Only carefully dried insulation materials ensure a trouble-free operation of electric high-performance components and slow down the aging process. For the materials used to insulate transformers it is extremely important to minimize moisture to guarantee dielectric strength and dimensional stability.

Vacuum Infusion Equipment

HEDRICH has developed vacuum infusion equipment for the casting of rotor blades for wind energy systems and composite components. The process taking place under vacuum increases the quality of the products.
