SESCO’s roots extend all the way back to the early 1900's and Bowser, Inc., a Fort Wayne, Indiana-based pioneer in oil dispensing, conditioning, and purification.

When the Bowser corporation relocated in 1969, SESCO was born. The new company focused on the design, manufacture, and repair of oil- and fuel-dispensing systems. Its product scope quickly grew to include custom-engineered lubrication, filtration, and hydraulic systems. 

It was in 1982 that SESCO manufactured its first vacuum oil dehydration system. By 1986 high-vacuum degasification systems had been added to the product mix.


SESCO is a major supplier of a wide range of power transformer service and installation processing equipment. The scope of supply includes mobile and stationary insulating oil purifiers, synthetic natural ester dielectric fluid conditioning systems, insulating oil regeneration systems, on-line transformer oil purification systems, insulating oil conditioning and filling systems, vacuum line moisture cold traps, dry breathing air systems, and transformer evacuation systems. Easily portable filtration, vacuum, and dry air trailers are also available. High efficiency lube oil vacuum dehydrators are available for standard high-water ingression applications and can also be custom built to your needs.

Training and Service

Building long-term customer relationships is SESCO’s primary goal. To achieve it, we offer ongoing training, support, and service. This includes free factory training for every piece of equipment sold. Onsite training and service are available, too – by annual contract or on a per-incident basis. And if a customer has a problem? Our expert troubleshooters are only a phone call away.
