Steel & Aluminum
Slide
SESCO delivers oil purification systems engineered to keep critical mill and plant equipment operating reliably under extreme conditions.
Slide
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.

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.
Slide
Dependability that extends oil service life and supports predictive maintenance strategies across integrated mill operations.
