SHUMEI KQ-AS2000GVDE Triple-Frequency Programmable Temperature-Controlled Ultrasonic Cleaner

Overview

The SHUMEI KQ-AS2000GVDE is a high-capacity, triple-frequency programmable ultrasonic cleaner engineered for demanding laboratory, pharmaceutical, and precision manufacturing environments. It operates on the principle of cavitation-induced acoustic energy transfer—where controlled ultrasonic waves generate microscopic implosions in the cleaning solution, effectively dislodging particulate contaminants, organic residues, and biofilms from complex geometries without mechanical abrasion. Unlike single-frequency systems, its tri-band capability (45 kHz, 80 kHz, and 100 kHz) enables selective optimization: lower frequencies deliver higher cavitation intensity for robust particulate removal from heavy-duty components, while higher frequencies provide finer resolution for delicate optics, microfluidic devices, or MEMS assemblies. The integrated temperature control system—featuring 9000 W heating and 1500 W active cooling—maintains stable bath conditions across the full 0–80 °C range, supporting temperature-sensitive cleaning protocols such as enzymatic debridement or low-volatility solvent applications. Its 160 L tank volume accommodates large batches or oversized instrumentation, including chromatography columns, reactor vessels, and surgical instrument trays.

Key Features

• Triple-frequency ultrasonic generation (45 / 80 / 100 kHz) with user-defined switching intervals (0–999 s), enabling multi-stage cleaning sequences optimized for heterogeneous contaminant profiles.
• Microprocessor-based digital control system with non-volatile memory: retains user-defined parameters—including power level (40–100%), frequency selection, dwell time (1–480 min), and target temperature—across power cycles.
• Full stainless-steel construction using ASTM A240 Type 304 grade material for corrosion resistance, structural integrity, and compliance with ISO 13485 cleanroom-compatible fabrication standards.
• Real-time monitoring and safety interlocks: simultaneous display of actual vs. set temperature, liquid level, ultrasonic output status, and fault diagnostics (e.g., low-level cutoff, overcurrent, overtemperature).
• Motorized acoustic damping lid with position-sensing actuation ensures consistent sound attenuation (reducing ambient noise to ≤65 dB(A)) and prevents operator exposure to airborne aerosols during operation.
• Electrically actuated inlet and drain valves support automated fill-and-drain cycles, minimizing manual handling and enhancing repeatability in GLP/GMP workflows.

Sample Compatibility & Compliance

The KQ-AS2000GVDE is validated for use with aqueous solutions, mild alkaline detergents, and low-boiling-point solvents compatible with 304 stainless steel. Its design conforms to IEC 61000-6-3 (EMC emission limits) and IEC 61000-6-2 (immunity requirements). The temperature control system meets ASTM E2912-22 criteria for thermal stability in laboratory cleaning equipment. Optional documentation packages support IQ/OQ validation per FDA 21 CFR Part 11 when paired with SHUMEI’s optional audit-trail-enabled software module. The unit complies with EN 61000-3-2 harmonic current limits and carries CE marking for electromagnetic compatibility and low-voltage directive adherence.

Software & Data Management

While the base configuration features an embedded LCD interface with tactile keypad navigation, optional RS485/Modbus RTU or Ethernet TCP/IP connectivity enables integration into centralized lab management platforms. Logged operational data—including start/stop timestamps, temperature ramp profiles, frequency transition events, and power modulation history—can be exported in CSV format for traceability. When configured with SHUMEI’s CleanLog™ firmware extension (sold separately), the system supports electronic signatures, user role-based access control, and 21 CFR Part 11–compliant audit trails—including immutable records of parameter changes and emergency stop events.

Applications

• Pharmaceutical: Pre-sterilization cleaning of stainless-steel vials, isolator components, and filtration housings prior to depyrogenation.
• Medical Device Manufacturing: Removal of machining oils, polishing compounds, and residual adhesives from orthopedic implants and endoscopic instruments.
• Research Laboratories: Surface preparation of SEM/TEM samples, cleaning of quartz cuvettes and optical filters without micro-scratching.
• Electronics: De-fluxing of PCB assemblies and ultrasonic-assisted rinsing of wafer carriers in Class 1000 cleanrooms.
• Quality Control: Standardized cleaning validation per USP “Cleaning and Cleaning Validation” guidelines for reusable analytical hardware.

FAQ

What is the maximum allowable operating temperature for aqueous cleaning solutions?
The system maintains precise thermal control up to 80 °C; however, sustained operation above 65 °C with water-based solutions requires verification of vapor pressure limits and local ventilation capacity.
Can the unit operate continuously for extended durations?
Yes—the 2000 W transducer array and forced-air-cooled power supply are rated for continuous duty at 100% output, provided ambient temperature remains below 35 °C and maintenance intervals (e.g., transducer coupling gel inspection) are observed per the service manual.
Is third-party calibration certification available?
SHUMEI provides factory calibration certificates traceable to NIM (National Institute of Metrology, China); accredited third-party calibration (e.g., ISO/IEC 17025) can be arranged through authorized regional partners.
Does the filtration system remove sub-micron particles?
The integrated bypass filter has a nominal retention rating of 5 µm; for sub-micron particle control, SHUMEI recommends pairing the unit with an external recirculating filtration skid equipped with 0.45 µm membrane cartridges.
How is acoustic uniformity verified across the tank volume?
SHUMEI performs aluminum foil erosion testing per ASTM D2603-20 Annex A1 during final QA; users may conduct periodic verification using standardized foil test kits aligned with ISO 13097:2012 guidelines.
