products: vacuum pressure impregnation and dip tank systems

HeatTek, Inc offers a complete line of vacuum pressure impregnation and dip tank systems including vacuum pressure impregnation (VPI) systems, vacuum only impregnation (VOI) systems, dip tank impregnation systems and impregnation system retrofits and upgrades. This VPI equipment is typically used throughout the OEM electric motor and generator industry, OEM transformer industry as well as the electric motor repair industry in order to seal and/or coat porous parts without negatively affecting the functionality of a part.
Our scope of supply includes new vacuum pressure systems, used systems (when available), as well as upgrading and retrofitting existing customer systems. HeatTek, Inc can also integrate and automate all aspects of product movement pre and post impregnation process. This capability is especially valuable in the OEM motor and transformer manufacturing, assuring product process reliability while minimizing manpower requirements, and time.
