GN Solids Control successfully participated in the 2025 China International Trenchless Technology Conference (ITTC), one of the most significant annual events in China’s trenchless technology sector. The exhibition brought together top manufacturers, engineering experts, and industry professionals to share the latest innovations and solutions for trenchless construction.
During the event, GN showcased two of its key technologies that drew significant attention from attendees:
1. TBM Slurry Separation System – Model GNTBM-360B
This system is designed specifically for tunnel boring machine (TBM) projects and includes GN’s high-efficiency double-deck shale shaker GNZS1536-2A. The unit demonstrated excellent performance in removing large solids from slurry in shield tunneling applications.
-
Vibration amplitude: 4–8 mm
-
Double-deck screen configuration: Enhances capacity and separation efficiency
-
Compact footprint: Suitable for confined or urban project sites
Visitors at the booth appreciated the practicality of the design and its ability to improve fluid recycling and reduce environmental impact.
2. Decanter Centrifuge – Model GNLW632B
GN also exhibited the GNLW632B dewatering decanter centrifuge, a robust and high-capacity unit for separating fine solids from drilling fluids and slurry. It’s engineered for applications outside the oilfield, such as municipal engineering, HDD, and trenchless drilling.
Key features:
-
High G-force for improved separation
-
Wear-resistant materials for longer service life
-
Easy operation and low maintenance
GN’s participation in ITTC 2025 reaffirmed the company’s dedication to advancing separation technology for the trenchless industry. Many attendees stopped by to discuss system customization, project integration, and technical support.
We thank everyone who visited our booth and shared insights on current challenges in trenchless construction. GN Solids Control remains committed to providing efficient and reliable solutions for your fluid management needs.
