Mobile Oil Purification & Transformer Dryout Systems

System Uses

These systems are designed to very thoroughly degas, dehydrate and remove fine particles and carbon fines to quickly restore the dielectric strength of transformer oil and insulating oil in transformers, load tap changers and oil filled circuit breakers.

They are available in a variety of configurations and process flow rates from 5 GPM to 50 GPM.

System Features

The heart of each system is a powerful purifier that uses heat in combination with deep vacuum to rapidly remove dissolved combustible gases and moisture to less than 10 PPM. The system also includes multiple stages of Absolute rated filters for the removal of fine particles. Common options include Fullers Earth treatment vessels for acid reduction, processing and storage tanks, 3-Phase electrical generator to supply the proper power to the system and oxidation inhibitor introduction devices.

Most of these Mobile Oil Purification Systems (MOPS) include powerful vacuum pumps with auxiliary connection points that allow for easy connection to transformers in order to apply deep vacuum during maintenance or commissioning of new units.

We build these systems in custom heavy-duty trailers and 4 X 4 box trucks with a long list of options to meet your specific needs. We specialize in delivering powerful systems in compact and highly portable and maneuverable platforms for use in sub-stations, power plants and switchgear yards.

Please inquire and let us help select the features that best meet your requirements. We offer rugged designs and options to meet nearly any application.
