SESCO delivers oil purification systems engineered to keep critical mill and plant equipment operating reliably under extreme conditions.
SESCO oil purification systems keep critical equipment clean, stable, and running.
Designed for continuous operation in metals manufacturing environments, SESCO lube oil purification systems remove water, metal fines, gases, and oxidation byproducts that compromise hydraulic and lubrication performance. Excelling in high water contaminant environments our equipment stabilizes system pressure and extends equipment life across high-load applications. SESCO purification systems support:
• Rolling mill hydraulic and lubrication systems
• Gearboxes and circulating oil systems
• Compressors, blowers, and pumps
• Turbines and generators
SESCO systems dependability protects servo valves, bearings, and high-precision components while reducing the risk of failures that interrupt production.
Oil purification equipment for the steel and aluminum industry.
Lube Oil Dehydrator
SES300

The SES300 purifiers are high-efficiency vacuum distillation systems. Compared to the typical “mass transfer” vacuum dehydrator the SES300 will remove 5X-10X the amount of water contamination per pass.
Dependability that extends oil service life and supports predictive maintenance strategies across integrated mill operations.
Scalability & Operational Continuity
Built on more than 80 years of proven engineering from our Bowser Inc. heritage, every SESCO system is configured to match real-world plant conditions.
Complete Lifecycle Support
We work directly with maintenance and reliability teams to deliver solutions that improve uptime, lower lifecycle cost, and protect critical assets in demanding steel and aluminum environments.
Precision Engineering
Achieve consistent performance in the toughest conditions with field-validated systems built for high moisture removal, heavy-duty degasification, long duty cycles, and site-specific configurations.
