Shumei KQ-AS2000DE Digital Ultrasonic Cleaner

Overview

The Shumei KQ-AS2000DE Digital Ultrasonic Cleaner is an industrial-grade, general-purpose ultrasonic cleaning system engineered for reproducible, high-efficiency removal of particulate contaminants, organic residues, and loosely adhered films from complex-surface components in laboratory, quality control, and light manufacturing environments. It operates on the principle of cavitation-induced micro-jetting and acoustic streaming generated by piezoelectric transducers bonded to the stainless-steel tank base and walls. At a nominal frequency of 40 kHz, the system delivers uniform energy distribution across its large-volume 160 L chamber (internal dimensions: 800 × 500 × 400 mm), enabling effective cleaning of large batches or oversized items such as glassware assemblies, metal fixtures, filtration housings, and precision optical mounts. The unit integrates digital microcontroller-based operation with real-time feedback monitoring, supporting precise protocol replication required under GLP, ISO 13485, and ASTM D2603-compliant cleaning validation frameworks.

Key Features

• Microprocessor-controlled interface with digital display of actual and set values for ultrasonic power (40–100% of 2000 W), temperature (ambient to 80 °C), and timer (1–480 min)
• Robust 304 stainless-steel construction for tank, lid, and internal support structures—resistant to corrosion from aqueous, alkaline, and mild solvent-based cleaning solutions
• Electrically actuated sound-dampening lid with safety interlock, reducing operational noise to ≤65 dB(A) at 1 m distance
• Integrated electric auto-fill and auto-drain system with level sensors, supporting programmable solution exchange and minimizing manual handling
• Multi-stage protection circuitry: low-level fluid detection, overtemperature cutoff, overcurrent shutdown, and dry-run prevention
• Onboard solution filtration module with removable stainless-steel mesh filter (standard pore size: 100 µm), enabling continuous recirculation and particulate retention
• High-efficiency transducer array (rated at 50 W per element, 40 kHz resonance) optimized for coupling into water and aqueous detergent media

Sample Compatibility & Compliance

The KQ-AS2000DE accommodates a broad range of sample types—including borosilicate glassware, stainless-steel tools, ceramic substrates, aluminum alloy parts, and polymer components—provided they are compatible with aqueous or low-volatility cleaning chemistries operating below 80 °C. Its sealed tank design and thermal insulation meet IEC 61000-6-3 EMC emission limits and comply with IP22 ingress protection standards. While not certified to UL/CSA for North American markets, its electrical architecture (AC 380 V / 50 Hz, three-phase) aligns with CE-conformant industrial equipment specifications. For regulated environments, the unit supports documentation of cleaning parameters via external data logging; however, it does not include FDA 21 CFR Part 11-compliant audit trail functionality out-of-the-box.

Software & Data Management

The KQ-AS2000DE utilizes embedded firmware without external PC connectivity or proprietary software. All operational parameters—including power level, temperature setpoint, elapsed time, and real-time tank temperature—are retained in non-volatile memory after power cycling. The controller logs fault events (e.g., “Low Level”, “Overtemp”) with timestamped status indicators visible on the front-panel LCD. For integration into validated cleaning workflows, users may record parameter settings manually or interface the unit’s analog/digital I/O ports (optional expansion) with third-party SCADA or LIMS systems using standard 4–20 mA or Modbus RTU protocols.

Applications

• Routine cleaning of volumetric flasks, centrifuge rotors, and HPLC sample vials prior to analytical use
• Preparation of metal calibration standards and reference artifacts for dimensional metrology labs
• Removal of polishing compounds and oxide layers from semiconductor wafer carriers and photomask frames
• Decontamination of reusable filtration devices used in bioprocessing and pharmaceutical water systems
• Supporting ASTM E1999 and ISO 14644-1 particle-counting validation through standardized ultrasonic rinse protocols
• Batch cleaning of surgical instrument trays in research animal facilities under AAALAC-aligned SOPs

FAQ

Is the ultrasonic frequency adjustable?
No—the transducer array is fixed at 40 kHz, optimized for general-purpose cleaning in aqueous media.
Can the unit be operated with solvents other than water?
Only low-flashpoint, non-flammable aqueous-compatible detergents or ethanol/water mixtures below 40% v/v are recommended; flammable solvents are prohibited due to lack of explosion-proof certification.
Does the system include heating element redundancy?
It features a single 9 kW immersion heater with dual independent thermal fuses and PID-controlled regulation for stable ±2 °C accuracy across the 20–80 °C range.
What maintenance is required for long-term reliability?
Monthly inspection of the stainless-steel filter basket, quarterly verification of transducer adhesion integrity, and annual calibration of the PT100 temperature sensor using traceable reference standards.
Is remote monitoring or Ethernet connectivity available?
Not natively—the unit lacks built-in network interfaces, but optional I/O modules enable integration with facility-wide automation platforms via dry-contact relays or analog signal outputs.
