2mag MIXdrive Industrial Magnetic Stirrer

Overview

The 2mag MIXdrive Industrial Magnetic Stirrer is a high-performance, contactless magnetic drive system engineered for robust, maintenance-free operation in demanding process environments. Unlike conventional stirrers relying on rotating shafts or gear mechanisms, the MIXdrive employs a patented electromagnetic induction principle: a stationary coil generates a rotating magnetic field via alternating current, coupling torque wirelessly to the stirring bar through ferromagnetic materials—eliminating mechanical wear, sealing challenges, and lubrication requirements. This architecture delivers exceptional long-term stability and repeatability, especially critical for continuous 24/7 operation in pilot-scale reactors, bioprocessing vessels, and chemical synthesis systems. Designed and manufactured in Germany, the MIXdrive meets stringent industrial reliability standards while maintaining full compatibility with GLP- and GMP-aligned workflows where traceability, operational integrity, and contamination control are mandatory.

Key Features

• Contactless induction drive: No moving parts inside the motor housing—zero mechanical wear, zero maintenance over lifetime
• High-torque magnetic coupling: Capable of transmitting rotational force through container walls up to 60 mm thick, including double-walled or jacketed reactors
• Stainless steel (AISI 304) housing: IP64-rated enclosure ensures resistance to dust ingress and low-pressure water splashes; fully cleanable under running water
• Wide speed range: Precisely adjustable from 120 to 1,200 rpm with stable torque delivery across the entire range—even at low speeds for viscous media (e.g., polymer solutions, cell culture broths, suspensions)
• Thermal resilience: Compatible with vessel bottom temperatures up to 200 °C; housing remains safe to touch under normal ambient conditions
• Compact footprint: 260 × 260 mm base area enables integration into confined spaces or modular process skids
• Low-voltage operation: 24 V DC input enhances intrinsic safety in hazardous or wet environments and simplifies integration with PLC-controlled systems

Sample Compatibility & Compliance

The MIXdrive supports stirring of liquids, slurries, and highly viscous media—including non-Newtonian fluids—within single-vessel configurations up to 250 L per stirrer position. Its strong magnetic coupling accommodates standard PTFE- or glass-coated stir bars (recommended length: 80–120 mm), as well as custom-engineered bars for specialized geometries. The device complies with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for industrial environments. While not certified for ATEX or IECEx zones, its 24 V DC architecture and sealed construction support use in non-classified areas adjacent to classified zones when installed per local electrical codes. All units are CE-marked and conform to RoHS and REACH directives. For regulated applications (e.g., pharmaceutical manufacturing), the optional MAXcontrol controller provides audit-trail-capable parameter logging compliant with FDA 21 CFR Part 11 requirements when deployed with validated software.

Software & Data Management

The MIXdrive operates standalone but achieves full process integration when paired with the MAXcontrol digital controller—a DIN-rail mountable unit supporting RS485 Modbus RTU communication. MAXcontrol enables remote speed setpoint adjustment, real-time RPM monitoring, runtime logging, and event-triggered alarms (e.g., stall detection, overtemperature). Data export is supported via USB or SD card in CSV format for post-processing in LIMS or MES platforms. Firmware updates are performed via secure signed binaries, ensuring version control and cybersecurity alignment with IEC 62443-3-3 guidelines. No proprietary cloud services are required; all data remains on-premise unless explicitly routed by user-defined network policies.

Applications

The MIXdrive serves mission-critical roles across multiple regulated and industrial domains: continuous mixing in API crystallization reactors; homogenization of vaccine adjuvants and monoclonal antibody formulations; agitation of high-viscosity fermentation media in single-use bioreactors; solvent blending in fine chemical synthesis; and uniform dispersion of nanoparticles in coating formulations. Its reliability makes it suitable for ISO 13485-certified medical device manufacturing lines, ASTM D2196-compliant rheological testing setups, and EN 14113-verified environmental sample preparation workflows. In academic and government labs, it supports long-duration kinetic studies requiring unattended operation over weeks without drift or failure.

FAQ

Is the MIXdrive suitable for use with glass-lined or double-jacketed reactors?
Yes—the 60 mm effective magnetic transmission depth allows reliable coupling through thick vessel bottoms, including enamel-coated steel and dual-layer stainless-steel jackets.
Can multiple MIXdrive units be synchronized for parallel operation?
When controlled via MAXcontrol with Modbus RTU daisy-chaining, up to 32 units can share a common speed reference and maintain phase coherence within ±2 rpm tolerance.
Does the device require calibration for speed accuracy?
No—speed is governed by precise frequency control of the induction field; factory calibration is traceable to national metrology institutes (PTB, Germany), and no user recalibration is needed.
What stir bar specifications are recommended for optimal performance at 250 L scale?
A 100 mm × 15 mm elliptical PTFE-coated stir bar with internal neodymium magnet (grade N52) is validated for laminar-to-turbulent transition in cylindrical vessels of ≥1.2 m diameter.
Is the MIXdrive compatible with automated process control systems?
Yes—RS485 Modbus RTU interface supports seamless integration with Siemens S7, Rockwell ControlLogix, and Beckhoff TwinCAT PLC platforms using standard function code 03 (read holding registers).
