Energy & Power Production: LS315W II Two-Stage Compressors in a Cogeneration Power Plant

As a key regional provider of combined heat and power, the client operates 24/7 under high-load conditions, supplying compressed air for flue gas desulfurization and denitrification processes, pneumatic valves and instrumentation, and system purging. Their operations face highly variable air demand, strict continuity requirements, and opportunities for improved operational efficiency.

The retrofit project required replacing aging compressors from other brands while maintaining core functions, including IoT connectivity, remote start/stop, and local/remote signal switching. Legacy compressors suffered from high energy consumption, insufficient pressure stability, and limited intelligence, unable to meet the plant’s goals for energy efficiency, emissions reduction, and digital operation.

Solution: LS315W II Two-Stage Compressors

Linghein recommended the LS315W II two-stage compressors to replace the high-energy units, addressing the plant’s operational and digital requirements. The solution focuses on three key aspects:

· High Efficiency: Two-stage compression achieves near-isothermal operation and national Class 1 energy efficiency, reducing electricity consumption at the source.

· Stable Supply: Optimized equipment selection and system design ensure consistent pressure, reliable supply under highly fluctuating demand, and minimized no-load energy loss.

· Intelligent Operation: Integrated IoT-based monitoring enables real-time system oversight, predictive maintenance, fault alerts, and supports low-staff operation, boosting operational efficiency and digital management.

Since deployment, the LS315W II units have delivered stable, reliable compressed air, significantly reducing energy costs while enhancing operational efficiency and digital management. The solution has enabled the client to progress toward a greener, high-quality operational model.

The LS315W II is ideal for high-demand energy and power applications. Featuring high-efficiency two-stage air-ends, it lowers overall energy consumption compared with traditional single-stage compressors while maintaining Class 1 energy efficiency.

Linghein continues to leverage innovation in two-drive, high-efficiency, and two-stage technology, expanding its high-end product portfolio. By providing advanced, intelligent compressed air solutions for cogeneration and energy sectors, Linghein empowers industrial clients to achieve energy savings, emissions reduction, and sustainable growth.
