At the Offshore Technology Conference (OTC) 2025 in Houston, GN Solids America once again proved its commitment to providing field-ready solutions for the oil & gas and environmental sectors. The company’s booth attracted significant attention from operators, service providers, and environmental consultants looking for compact, reliable, and cost-effective separation equipment.

A major highlight at the booth was the GNLW223D Decanter Centrifuge, a compact 9-inch unit tailored for projects where space and capacity are limited but performance cannot be compromised. Whether it’s for small-scale tank cleaning, offshore pilot projects, or core drilling fluid recycling, the GNLW223D offers impressive dewatering and clarification capabilities. With a bowl speed up to 4500 RPM and VFD control, users can fine-tune operations for maximum efficiency.

GN also showcased its GNSP-10B vacuum pump, designed to transfer drilling waste, oil sludge, or tank bottom residue over long distances—without using electricity. The pump’s air-driven, explosion-proof design makes it ideal for hazardous zone operations, such as offshore platforms or remote oilfields. Its simple yet durable construction ensures minimal maintenance and reliable performance in the toughest conditions.

The GNZS series shale shaker, displayed alongside, caught the eye of many mud engineers and drilling supervisors. Known for its high G-force linear motion and composite screens, it offers effective primary solids control to protect downstream equipment and extend fluid life.

What resonated most with visitors was GN Solids America’s practical approach: modular designs, real inventory in Houston, and responsive service backed by engineering expertise from GN’s global team. Many customers appreciated the ability to scale up from lab-sized units like GNLW223D to full systems for large oilfield or environmental projects.

Our team was excited to meet with clients from the U.S., Latin America, Canada, and beyond, many of whom were looking for local support, fast delivery, and a trustworthy partner in solids control. GN Solids America’s Houston warehouse, technical service team, and inventory of spare parts make us uniquely positioned to serve these needs with minimal lead time.

Participating in OTC 2025 not only strengthened our brand visibility but also provided valuable feedback from end users and industry experts. It reaffirmed our mission to keep innovating and to support our partners in the oil & gas, mining, construction, and environmental sectors.

We extend our gratitude to everyone who visited our booth and shared their insights and requirements. The GN team looks forward to continuing these conversations and building successful partnerships in the months ahead.

GN Separation has successfully completed the manufacturing and factory testing of 8 sets of stack vibrating screens, which are now ready for shipment to a domestic client specializing in mineral processing.

These vibrating screen units are part of GN’s stacked design series, engineered to deliver higher screening efficiency in a smaller footprint. Each unit is composed of multiple screen decks stacked vertically, significantly increasing capacity while maintaining compact equipment dimensions — ideal for facilities where space optimization is a key requirement.

Key Features of GN Stack Vibrating Screens:
• Multi-deck design: 2 to 5 screen layers to increase processing capacity
• Compact footprint: ideal for limited installation spaces
• High G-force linear motion: improves fine particle separation
• Modular design: easy maintenance and part replacement
• Sturdy carbon steel structure: designed for heavy-duty industrial applications

These units will be used in a mineral classification process that requires precise cut points and minimal downtime. The stack design allows simultaneous processing of multiple material sizes, reducing the need for additional screening equipment and minimizing energy consumption.
Before shipment, each vibrating screen passed a comprehensive quality check, including:
• Structural integrity inspection
• Motor alignment and vibration test
• Screen mesh tensioning validation
• Control panel functionality test
The client has worked with GN Separation on previous projects and has opted again for GN due to the equipment’s high durability, stable performance, and short delivery times. Additionally, GN provided detailed installation drawings, operating manuals, and offers remote technical support for the commissioning phase.

These stack vibrating screens are just one example of how GN continues to support its clients with customized, reliable separation solutions across industries such as mining, metallurgy, and chemical processing.

GN Solids Control recently delivered a complete Modular Hydrovac Slurry Dewatering System to an overseas client for efficient handling and treatment of hydrovac slurry generated during excavation activities. This system is specifically designed to separate solids and recover reusable water, reducing disposal volume and environmental impact.

Complete Modular Configuration
The delivered system is composed of five integrated modules, each engineered for a specific separation stage to ensure optimal dewatering performance:
🔹 Coarse Screening Module (GNLMP-1536)
The process starts with a coarse screen unit that removes large-size debris such as rocks, wood and heavy trash from incoming slurry. This step significantly reduces the burden on downstream equipment and helps maintain steady flow.
🔹 Double Deck Fine Shaker Module (GNZS596K)
Next, the slurry passes through a high-capacity double-deck shale shaker designed to remove fine solids efficiently. The dual-layer screen design maximizes throughput while maintaining effective solid-liquid separation.
🔹 Desilter Module (GNZJ594J-8N)
Equipped with multiple 4-inch hydrocyclones, this unit targets the removal of particles in the 20–40 micron range. The desilter is essential for reducing solids loading before entering the centrifuge stage.
🔹 Decanter Centrifuge Module (GNLW553D-VFD)
This high-speed VFD-controlled centrifuge performs precision separation of ultra-fine solids. With a large 22-inch bowl, the GNLW553D is ideal for heavy-duty slurry treatment and can handle high volumes while delivering excellent clarity of recovered water.
🔹 20-ft Chemical Dosing System
To improve the separation efficiency of fine and ultra-fine solids, GN Solids Control integrates a fully automated flocculant preparation and dosing unit. This module ensures stable and accurate polymer mixing and dosing, enhancing the dewatering process.

Benefits and Application
The modular design provides several advantages:
✅ Scalable & Flexible Setup – Each unit is built into standard-sized frames or containers, enabling easy transportation, on-site installation, and customization according to client needs.
