SESCO provides upgrade and modernization services for aging oil processing systems, helping utilities and industrial operators extend equipment life while improving performance, reliability, and safety.
Many upgrades are relatively minor—such as replacing outdated controls or instrumentation—but even major system rebuilds can be economically justified when core components remain structurally sound. With decades of experience manufacturing and servicing oil purification equipment, SESCO can evaluate existing systems and recommend the most cost-effective upgrade path.
In many cases, upgrading a system allows operators to gain modern functionality and reliability without the cost of a full equipment replacement.
SESCO performs upgrades on both SESCO-built units and equipment manufactured by other suppliers.

Upgrades can significantly improve system performance, extend service life, and bring older equipment in line with modern operating and safety standards.
