SESCO engineers, designs, and manufactures mobile insulating oil filtration systems for small transformer, tap changer, and breaker installation and maintenance. These systems are targeted for less-demanding low-volume applications where dissolved gas contamination is not an issue. The SES 441 series uses single or multi-stage filtration to remove, particulate, free water, and small quantities of dissolved water if necessary. The SES441 filtration systems are commonly trailer mounted and can be combined with stand-alone vacuum (SES420) and dry breathing air packages (SES329) to increase the versatility of the maintenance trailer.  All systems can be custom built to customer specifications.
