GN Solids Control has successfully delivered 3 sets of self-contained HDD mud recycling systems to a European client, including 2 units of GNMS-400C and 1 unit of GNMS-200C — both belonging to the brand’s Self-Contained Mud Recycling series.

The GNMS C series (represented by GNMS-400C) is an all-in-one solution, integrating mud recycling, storage, and mixing functions to suit space-constrained HDD job sites. Key specs differentiate the two models: the GNMS-400C offers 100 m³/h (440GPM) capacity, equipped with a GN cleaner (GNZS594K-S8NK) and mixing hopper. The GNMS-200C provides 45 m³/h

(200GPM) capacity, paired with its own cleaner (GNZJ754K-S4NK) and matching hopper.
Tailored for European HDD projects, these systems optimize mud treatment efficiency, reduce waste, and cut on-site costs. This shipment reinforces GN’s status as a trusted provider of specialized HDD mud solutions for global trenchless construction sectors.
