What equipment will be showed at the ITTC 2026 exhibition?
1. HDD mud recycling system: GN HDD Mud Recycling System (Horizontal Directional Drilling Mud Recycling System) is a modular solids control solution designed to recover and reuse drilling fluids (bentonite mud) in trenchless industry. It reduces waste disposal costs, minimizes environmental impact, and protects high-pressure pumps by removing excavated solids .The system typically integrates multi-stage separation and auxiliary components on a single skid mounted mud tank or trailer mounted mud tank. Here is the standard configuration breakdown: the 1st stage: shale shaker to separate coarse solids; the 2nd stage: desander cone to separate the cut point 45~75 microns; 3rd stage: desilter cone to separate cut point 25~45 microns; the 4th stage: decanter centrifuge to remove ultra fine solids; The other equipments including customized design mud tank, mixing hopper, mixing pump, electrical control system, lightings, mud agitators, etc.


2. TBM slurry separation system: GN TBM (Tunnel Boring Machine) Slurry Separation System is a high-capacity solids control solution engineered specifically for Slurry Shield TBM and Microtunneling projects. It is designed to separate excavated soil and sand from bentonite slurry, allowing for continuous recycling of the drilling fluid and efficient management of muck disposal. GN offers standardized skid-mounted or containerized plants based on TBM diameter and excavation rate: GNTBM-260 (260m3/h), GNTBM-360 (360m3/h), GNTBM-500 (500m3/h), GNTBM-800B (800m3/h), GNTBM-1000B (1000m3/h), GNTBM-1500B (1500m3/h) and higher treating capacity TBM slurry separation plant up to 3000m3/h for Large Diameter Road/Rail Tunnels.

GN 9 Sets Drilling Mud Vacuum Degassers for Europe Client

Recently 9 sets of drilling mud vacuum degassers are ready for delivery for Europe client.
GN Solids Control has established a strong presence in the European market, delivering its drilling mud vacuum degassers as part of comprehensive solids control systems. These units are specifically designed to meet the region’s stringent safety and quality standards, with multiple recent shipments highlighting their advanced features.


A key factor for the European market is that GN’s vacuum degassers are available with full ATEX explosion-proof and CE certificates. This ensures compliance with strict EU safety directives for equipment used in potentially explosive atmospheres, such as oil and gas drilling sites.
The major model vacuum degasser for Europe is GNZCQ270B and GNZCQ360 , these units are engineered to efficiently remove entrapped gases from drilling fluids . The vacuum-driven design ensures efficient gas separation without introducing air into the drilling mid, which helps prevent gas-cut mud, enhances centrifugal pump efficiency, and improves wellbore stability. The gas removal efficiency of gas is ≥95%.
Features of GN vacuum degasser:


1. The suction of the vacuum pump allows the mud to enter into the vacuum tank, let the gas out of the vacuum tank.
2. The water ring vacuum pump is suitable for flammable and explosive gas suction and operates safely and reliably.
3. The suction pipe inserts into the mud level and it can be used as high power mixer when there is no gas immersion in the mud.
4. The gas water separator can also supply circulating water to the vacuum pump to save water.
For European operators, GN’s vacuum degassers provide a certified, efficient, and robust solution for maintaining drilling fluid properties, ensuring safety, and meeting regulatory requirements. If you have details about your specific rig type or drilling environment, I can help you find more targeted information.
