Enervac Product Digest
ENERVAC has built a world-wide reputation for delivering high-performance engineered products that meet or exceed customer needs. In any climate or environment (including hazardous locations), ENERVAC liquid & gas processing and recovery systems provide the most efficient, cost-effective and reliable solutions available in the industry.
Transformer Oil Purification Systems
Vacuum Process for Dehydration & Degas of Transformer Oils
ENERVAC's high vacuum process for transformer oil purification is used to dehydrate and degasify electrical insulating liquids such as transformer oils, polybutene, and silicone fluids, enhancing and maintaining their dielectric strength. This process removes free and soluble water, dissolved air and gases, and particulate matter.
Key applications of high vacuum degasifiers are in extra high voltage transmission and electrical apparatus manufacturing. Additionally, the process is used for degasifying cable oils, including polybutene, and has applications beyond the electrical industry, such as in electronic and radar equipment, vacuum pump sealing oils, brake fluids, and refrigeration oils, including phosphate esters and silicones. Systems sizes range from large custom semi-trailer mounts with generators to a very portable ‘Mini’ degassifier hand cart for effective temporary degassing.

Enervac SF6 Gas Servicing Equipment
For Processing of Sulfur Hexafluoride used in High voltage Metal-Clad Switch Gear, Bus Ducts, Accelerators, and more
Sulfur Hexafluoride (SF6) is a highly effective gaseous dielectric for high voltage power applications. It has been widely used in high voltage circuit breakers and other switchgear in the power industry. SF6 applications include gas-insulated transmission lines and gas-insulated power distribution substations. The combined electrical, physical, chemical, and thermal properties provide numerous advantages for use in power switchgear. Notable properties of SF6 that make it desirable for power applications include:
- High dielectric strength
- Unique arc-quenching ability
- Excellent thermal stability
- Good thermal conductivity
Despite these advantageous properties, Sulfur Hexafluoride is a fully fluorinated compound (FFC). FFCs have atmospheric lifetimes of up to 50,000 years, meaning that these potent greenhouse gases could significantly and permanently contribute to global warming if emissions continue to increase. For instance, while CO2 has a global warming potential (GWP) of 1, SF6 has a GWP of 24,900. Additionally, over the past year, the price of new SF6 gas has surged by as much as 600%. Consequently, SF6 is primarily used in applications that allow for reclamation rather than in equipment that requires the release and refilling of the gas with new SF6. ENERVAC produces a comprehensive range of SF6 recovery and carts from the largest fastest HV, EHV ability mounted on skids or in cargo trailers to very portable MV hand cart versions.
