VMA Dispermat SC115 ATEX-Certified High-Speed Vacuum Dispersion System

Overview

The VMA Dispermat SC115 is a high-performance, ATEX-certified dispersion system engineered for reproducible, scalable laboratory and pilot-scale processing of demanding suspensions, pastes, and highly viscous formulations. Operating on the principle of high-shear rotor-stator hydrodynamic cavitation, the SC115 delivers controlled energy input through precisely engineered dispersing discs rotating at speeds up to 6,000 rpm—enabling particle deagglomeration, pigment wetting, nanomaterial dispersion, and homogenization of thermally sensitive or volatile systems. Its structural architecture integrates a rigid cast-iron base, dynamically balanced drive shaft, and sealed bearing housing rated for continuous duty under variable load conditions. Designed specifically for environments requiring intrinsic safety, the SC115 meets ATEX Directive 2014/34/EU for equipment intended for use in potentially explosive atmospheres (Gas Groups IIA–IIB, Temperature Class T4), making it suitable for solvent-based coatings, battery slurry preparation, pharmaceutical suspensions, and reactive resin systems.

Key Features

• ATEX-compliant explosion protection system certified for Zone 1 and Zone 2 hazardous areas—includes intrinsically safe instrumentation, spark-resistant motor housing, and grounded conductive tooling
• Integrated vacuum dispersion module capable of operating down to ≤10 mbar absolute pressure, minimizing oxidation, foaming, and solvent evaporation during high-energy processing
• Digital control panel with real-time monitoring of rotational speed (0–6,000 rpm), motor current draw (0–30 A), and product temperature (via optional Pt100 probe interface)
• Motorized vertical adjustment mechanism with ±0.1 mm positioning resolution and programmable descent profiles for repeatable immersion depth control
• Modular rotor-stator geometry support: interchangeable dispersing discs (Ø30–Ø90 mm), toothed stators, and high-torque anchor tools for viscous media handling
• PLC-based automation interface supporting Modbus RTU/TCP protocols for integration into centralized lab management systems and audit-ready process logging

Sample Compatibility & Compliance

The SC115 accommodates a broad range of sample types—from low-viscosity Newtonian liquids (e.g., aqueous polymer solutions) to non-Newtonian shear-thinning pastes (e.g., lithium-ion cathode slurries, ceramic ink formulations). Its sealed dispersion chamber and vacuum-rated gasketing allow safe processing of flammable solvents (e.g., NMP, acetone, xylene) without vapor accumulation. The system conforms to key international standards including EN 60079-0 (explosive atmospheres – general requirements), EN 60079-7 (increased safety “e” protection), and ISO 8502-9 (surface cleanliness verification prior to coating application). For regulated industries, the optional PLC controller supports 21 CFR Part 11-compliant electronic signatures, user access levels, and immutable audit trails required under GMP/GLP frameworks.

Software & Data Management

The SC115’s embedded controller stores up to 1,000 process recipes with parameter sets (speed ramp profiles, hold times, vacuum setpoints, temperature thresholds). Data export is supported via USB 2.0 or RS-485 to CSV or XML formats compatible with LIMS platforms such as LabWare or Thermo Fisher SampleManager. When configured with the optional VMA ProcessControl Suite, users gain access to time-stamped event logs, OEE metrics, deviation alerts, and automated report generation aligned with ISO/IEC 17025 documentation requirements. All firmware updates are delivered via signed binary packages verified against SHA-256 checksums to ensure integrity and traceability.

Applications

• Electrode slurry development for Li-ion and solid-state batteries—ensuring uniform conductive carbon distribution and binder dispersion without particle fracture
• High-solids-content pigment dispersions for automotive OEM coatings and aerospace sealants, where batch-to-batch color consistency is critical
• Pharmaceutical nanosuspension formulation under inert atmosphere to prevent API degradation during micronization
• UV-curable inkjet inks requiring sub-micron particle stability and narrow D50 distributions verified by laser diffraction
• R&D of conductive pastes for printed electronics, where agglomerate removal directly impacts sheet resistance and line resolution

FAQ

What ATEX zones does the SC115 support?
The SC115 is certified for use in Zone 1 (areas where an explosive atmosphere is likely to occur in normal operation) and Zone 2 (areas where an explosive atmosphere is not likely to occur but may persist for a short period if it does), per Directive 2014/34/EU.
Can the SC115 be integrated into an existing PLC-controlled production line?
Yes—the system provides native Modbus RTU and TCP/IP interfaces, enabling bidirectional communication with Siemens S7, Rockwell Logix, or Beckhoff controllers for synchronized start/stop, parameter upload, and fault reporting.
Is vacuum operation mandatory, or can the unit run at ambient pressure?
Vacuum operation is optional; the SC115 functions reliably under atmospheric conditions. The vacuum module is field-installable and requires connection to an external vacuum pump with oil mist filtration.
What maintenance intervals are recommended for the dispersing shaft and bearings?
Under standard laboratory use (≤4 hrs/day), VMA recommends greasing the angular contact ball bearings every 500 operating hours and inspecting the shaft runout annually using a dial indicator calibrated to ±1 µm tolerance.
Does the SC115 meet FDA requirements for pharmaceutical process equipment?
While the SC115 itself is not FDA-listed, its construction materials (316L stainless steel wetted parts, EPDM/FKM elastomers) comply with USP Class VI and FDA 21 CFR 177.2600 for indirect food additives, and its design supports cleaning validation per ASTM E3076-17.
