Combining an industry-standard thermo-vacuum oil purification process with Trojan’s experience and IP on energized transformer oil processing yields the Trojan TOVS (Transformer Online Vacuum System), designed for online, unattended removal of gases, moisture, and particulate matter.

Like the industry-leading Trojan Dry-Out System (TDOS), the TOVS provides PLC-controlled commissioning for energized transformers and the ability to reduce gas and moisture content to very low levels, which brings the oil DGA back to acceptable levels.

Utilizing the automated safety features built into all of Trojan’s systems, Operators can leave the TOVS to operate unattended on transformers of virtually any size, improving operating capability and extending the life of their transformer assets.
