SES320(R) Insulating Oil Processing Equipment

The SES320 family of stationary and mobile vacuum oil purifiers are used to prepare dielectric fluids for service, as well as vacuum dry and fill high voltage oil cooled equipment. After 30 years of production, the SES320 family can be found in power generation, transmission, distribution and transformer manufacturing industries world-wide. 

SES441 Substation Maintenance Trailers

Custom mobile insulating oil filtration systems are available for less-demanding low-volume applications where dissolved gas contamination is not an issue. The SES441 series uses single or multi-stage filtration to remove, particulate, free water, and small quantities of dissolved water if necessary. The systems are usually customized to suite the specific customer application.

Transformer Vacuum Dry-out Systems

The SES420 family of two stage vacuum packages are targeted at transformer dry out applications but can be custom engineered for other industrial applications on request. The SES420 series is packaged in four standard size ranges  and are available as stand-alone skids, stand-alone cargo trailer packages, and SES320 oil processor integrated.  

SES329 Transformer Back Fill Dry Air Systems

The SES329 series of mobile and stationary dry air generation systems are targeted for transformer back fill applications and are often purchased as accessories with our SES320 oil processing equipment. Non-certified and certified class "D" breathing quality options are available .

SES328 Transformer Evacuation Vacuum Line Cold Traps

The SES328 vacuum line cold traps are used to measure the rate and volume of water extraction during the transformer vacuum dry out process. An extraction rate is determined by measuring the collected ice (water) over a given time period. Refrigerated and liquid nitrogen cooled traps are available.

Transformer Vacuum Manifolds

The SES425 manifolds are designed for use on transformers with Qualitrol pressure relief valves. Evacuation and  Evacuation with hot oil spray versions are available. With an all aluminum construction, the SES425 series are easy to handle and maneuver into position on site. If Qualitrol pressure reliefs are not used the SES425 series will be custom...

Oil Booster Heating Systems

The SES460-2400  booster oil heating system is a versatile oil heating tool designed to aid oil processing in cold weather transformer installation and maintenance. The SES460-2400 can be set up to boost oil processor return or supply temperatures. It also can be being used as a stand-alone 40 GPM heating circulation system for preheating...
