Oil Filtration Systems

High Vacuum Transformer Oil Purification Systems (HVTOPS)

In order to achieve optimal dielectric strength and insulating performance inside of transformers and circuit breakers, dielectric oils must be kept absolutely clean and dry. Substation Maintenance Contractors and Utilities need a rig that can quickly and reliably process transformer oil to meet or exceed very stringent specifications, so Oil Filtration Systems, Inc. designs and builds the most effective, durable, and user-friendly Hi-Vac system on the market today. Special engineered design features maximize the water extraction rates of our systems, and top-quality components and workmanship ensure years of maintenance-free operation and performance.
