GN Speed Variable Frequency Centrifuges Power Southeast Asian Drilling Operations

In a significant milestone for solid control technology, GN Solids Control has successfully delivered three state-of-the-art high-speed variable frequency centrifuges to a leading drilling company in Southeast Asia. The shipment includes two sets of GNLW363D-VFD decanter centrifuge and one set of GNLW453D-VFD models, engineered to enhance drilling mud separation and waste management efficiency in demanding offshore and onshore environments.

At the core of these centrifuges lies advanced mechanical design tailored for high-performance separation. The GNLW series features a robust drum constructed from duplex stainless steel 2304, paired with a screw conveyor made of duplex stainless steel 2205, ensuring exceptional corrosion resistance and durability. The proprietary oil-lubricated main bearing system extends operational life, maintaining stability even at peak speeds. Notably, the lubrication protection system safeguards bearings for 5–10 minutes during unexpected power outages, preventing downtime.

With an industry-leading length-to-diameter ratio of 4.2:1 and deeper liquid pool depth, these centrifuges achieve superior solids recovery and larger processing capacities. The GNLW453D-VFD, with its larger drum diameter, excels in handling high-density slurries, while the GNLW363D-VFD models optimize finer particle separation. Both units operate at maximum speeds of 3,900 RPM, generating separation forces up to 3,063G for unparalleled efficiency.

The integrated variable frequency drive (VFD) system allows precise speed and differential adjustments via PLC-controlled interfaces. Real-time monitoring of torque, vibration, and temperature ensures proactive maintenance. Crown’s proprietary automation suite includes optional auto-flushing and chemical dosing systems, reducing manual intervention for clients managing complex drilling fluid systems.

The recipient drilling company prioritized Crown’s centrifuges for their proven reliability in high-temperature, high-pressure conditions—critical for Southeast Asia’s tropical drilling sites. The ATEX/IEC Ex-certified explosion-proof electrical components further mitigate risks in volatile environments. Post-sale, Crown’s local technical support network guarantees rapid response, minimizing operational disruptions.

This delivery underscores GN’s growing footprint in Southeast Asia’s energy sector, where efficiency and environmental compliance are paramount. By combining cutting-edge engineering with region-specific adaptations, GN continues to redefine solids control standards for the global drilling industry.
