Mineral Oils

The SES320(R) is designed to worst case single pass performance standards for mineral oil. The dissolved water saturation level is 90-100 ppm at typical ambient temperatures.

Natural Ester Fluids

The flow capacity of the SES320(R) must be de-rated by 25% when processing Natural Ester Dielectric Fluids. At least two passes are recommended.

Synthetic Ester Fluids

The flow capacity of the SES320(R) must be de-rated by 25% when processing Synthetic Ester Dielectric Fluids. At least two passes are recommended.
