Vacuum Pressure (VPI) & Vacuum Only (VOI) Impregnation Systems
Vacuum Pressure (VPI) Impregnation Systems |
HeatTek, Inc offers a complete line of Vacuum Pressure Impregnation (VPI) and Vacuum Only Impregnation (VOI) Systems, Retrofits and Upgrades for systems, as well as Dip Tanks. This equipment is typically used throughout the OEM electric motor and generator industry, OEM transformer industry as well as the electric motor repair industry.
This area of HeatTek, Inc is overseen by Jeff Schein. Jeff has 25+ years of experience engineering, fabricating and commissioning impregnation systems of all types. HeatTek, Inc’s goal is to supply quality systems, focusing on the customer’s staff and facilities, resin selection, and process requirements. We will provide all aspects of the system design, as well as manufacture, install, commission, and service the system.
Our scope of supply includes new 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.
We look forward to the opportunity to meet with you, discuss your project requirements and then offer a comprehensive quote.
