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 HOT AIR DRYING EQUIPMENT The mature technology of our vacuum hot-air drying equipment provides excellent drying results. Benefit from a considerably reduced drying time! more VACUUM NITROGEN DRYING EQUIPMENT: HIGHER TEMPERATURES = SHORTER DRYING TIMES Our vacuum nitrogen drying equipment hit the mark by higher drying temperatures, reduced drying times and only minor depolymerization of the insulating paper. more LOW-FREQUENCY DRYING EQUIPMENT Low-frequency drying equipment are fitting well for the fully automatic production of transformers. Simultaneous heat and vacuum drying ensure short process times. more THE NEW GENERATION OF VAPOUR PHASE EQUIPMENT Vapour phase drying systems are used for the production of power transformers and other high-voltage components. The technology requires – compared with drying processes using air – about just 25-40% of the time. more VACUUM DRYING AND IMPREGNATING EQUIPMENT We deliver vacuum drying and impregnating equipment and oil purification equipment that are individually adapted to the requirements of oil/paper-insulated electric components. more VACUUM OIL PURIFICATION EQUIPMENT Whether in stationary or mobile design, vacuum oil purification systems of HEDRICH are characterized by a large vacuum degassing stage and an efficient pumping speed of the pumping unit. more VACUUM CABLE IMPREGNATION EQUIPMENT Specialized in the impregnation of signal and HV/HVDC energy cables, HEDRICH’s vacuum cable impregnation systems ensure absolute process reliability. And this is for more than 45 years. more ISOSTATIC PRESSES Using isostatic presses during the drying of transformer windings ensures that shrinkage of the insulation is compensated, resulting in a reduction of the plastic deformation. more SUBSCRIBE TO HEDRICH NEWSLETTER Send Contact Imprint Data privacy statement Cookie policy
