SES320 Insulating Oil Conditioning

Our 320 series of vacuum insulating oil purifiers are available in stationary and mobile configurations for oil conditioning and transformer service.

Slider

SES320 insulating oil conditioning systems prepare mineral and natural ester-based insulating fluids for transformer service. The SES320 conditioning systems are used in power and distribution transformer installation, maintenance, and production. The 320 series of purifiers are designed for single pass conditioning of new and in-service (Group I & II) insulating fluids. Insulating fluid breakdown voltage values (dielectric strength) are increased to acceptable levels by removing dissolved water, dissolved gas, solid matter contamination.

Mobile configurations of the SES320 are typically designed with transformer vacuum dry out capabilities. Numerous options are available to perform any transformer service oil or dry-out related function.

Treatment of severely degraded in-service oils (Group III) and transformer desludging require an additional treatment phase. The SES320R system incorporates an adsorbent treatment (Fullers Earth) stage for in-service group III oil regeneration.
