Desander (without bottom flow screen) exported to Germany

2025-09-24

1. Project Overview

A leading German drilling contractor specializing in unweighted drilling fluid treatment for water well and CBM (Coal Bed Methane) projects required a compact, cost-effective solids control solution. The client prioritized equipment compliance with EU industrial standards for limited mud system space. After technical verification, a desander unit with no underflow screen was selected and delivered in Q2 2024 .

TRCS3S-Desander

2. Equipment Configuration

Specification	Details
Model	CS240N (customized for European voltage standard)
Hydrocyclone Configuration	2 units of 10-inch polyurethane cones (wear-resistant, Mongoose-style design)
Processing Capacity	240 m³/h (1056 GPM)
Cut Point	45-76 μm (targeting abrasive solids post-shale shaker treatment)
Working Pressure	0.25-0.4 MPa (29-58 psi)
Structural Feature	No underflow drying shaker; integrated skid-mounted design for easy installation
Compliance Standards	API 13C, ISO 9001, and CE certification

3. Operational Performance

Space Efficiency: The no-underflow-screen design reduced the equipment footprint by 35% compared to traditional desanders with mini shakers, fitting the client’s compact mud tank layout .

Solid Removal Efficiency: Achieved 92% separation rate for 60+ μm particles, reducing wear on downstream desilters by 28% .

Cost Savings: Eliminated screen replacement and shaker maintenance costs, cutting operational expenses by €12,000 annually .
Environmental Adaptation: Operated stably at ambient temperatures of 6-40°C (typical for German drilling sites) with no performance degradation .

4. Client Feedback

“The desander’s compact structure and high separation efficiency perfectly match our unweighted mud treatment needs. Its compliance with European standards and low maintenance requirement have significantly improved our drilling productivity.” — Drilling Operations Manager, German Contractor
