At Enervac, sharing case studies from our customers is our way of showcasing real-world transformer oil purification challenges and how our equipment delivers results.

Recently, we heard from an engineering services firm in the Northeast U.S.:

“I’ve got a transformer with 1700 gallons of silicone fluid showing high water content. Do you have a rental processor for silicone? Need pricing for a one-week rental, all hoses delivered.”

Why Silicone Fluids Are Challenging

Unlike standard mineral transformer oils, silicone insulating fluids require special handling:

High viscosity makes dehydration slower and harder.
Thermal stability under vacuum must be maintained to avoid degradation.
Dielectric properties must be preserved while removing contaminants.

That’s where specialized vacuum dehydration and degasification systems come into play.

The Solution: Enervac E865A 1800 GPH Degassifier

Our recommendation was the E865A vacuum oil purifier and degassifier, designed for processing transformer oil, polybutene, and silicone fluids. Available as rental equipment, this system ensures moisture, gases, and particulates are effectively removed while maintaining the integrity of insulating liquids.

Key Performance Features:

Dehydration: At ~80 °F, water content can be reduced from 100 ppm to <10 ppm.
Degasification: Soluble air is cut from ~12% saturation down to <0.25% in a single pass, removing combustibles as well.
Particulate Removal: Down to 5 microns (with submicron capability via downstream filters).
Contaminant Control: With Fuller's Earth filters, the system also eliminates oxidation by-products, varnishes, acids, and sludge.

Rental Equipment, Same Enervac Quality

At Enervac, our rental transformer oil purification systems are supported with the same quality and service as our equipment for purchase. That means you get dependable performance, fast delivery, and expert support to keep your transformer systems running efficiently.

If you’re facing moisture, gas, or contamination problems in transformer oil, silicone fluid, or other insulating liquids, Enervac has the solution.
