Overview
The Shumei KQ-2000ZB Immersion Ultrasonic Transducer Plate is a high-power, digitally controlled ultrasonic energy delivery system engineered for integration into custom cleaning tanks, passivation baths, and inline decontamination workflows in pharmaceutical, biotechnology, and precision manufacturing environments. Unlike benchtop ultrasonic cleaners, this immersion-type transducer plate operates on the principle of piezoelectric resonance—converting high-frequency electrical signals (28 or 40 kHz) into mechanical vibrations transmitted directly through liquid media via a rigid stainless-steel radiating surface. Its design enables uniform cavitation field distribution across large-volume tanks (up to 200 L typical), supporting consistent particulate removal, biofilm disruption, and solvent-assisted degreasing without requiring tank redesign or retrofitting. The system is intended for permanent or semi-permanent installation in ISO Class 7/8 cleanrooms, GLP-compliant QC labs, and GMP-regulated production support areas where reproducible, traceable cleaning validation is required.
Key Features
- Stainless-steel transducer plate (800 × 450 × 100 mm) with fully welded, acid- and alkali-resistant 316L construction—certified for continuous operation in aggressive aqueous and mild organic solvent environments.
- Dual-frequency capability (28 kHz for heavy particulate removal; 40 kHz for fine-part cleaning and delicate substrate compatibility), selectable via digital control interface.
- 2000 W nominal output power with real-time adjustable range (0–100%) using constant-current regulation—ensures stable acoustic intensity regardless of load impedance shifts caused by temperature, liquid level, or fouling.
- Digital generator (370 × 290 × 130 mm) featuring auto-sweep, frequency tracking, and real-time impedance matching algorithms to maintain optimal electroacoustic coupling efficiency over time.
- Triple-parameter LED display showing instantaneous ultrasonic frequency, output current (A), and elapsed time—enabling operator verification and process documentation.
- Integrated thermal monitoring circuitry with automatic shutdown at >65 °C internal temperature; overcurrent protection and short-circuit immunity compliant with IEC 61000-4-5 surge immunity standards.
- Standard RS232 remote interface included; optional RS485 Modbus RTU protocol support for SCADA integration and centralized fleet management.
Sample Compatibility & Compliance
The KQ-2000ZB is validated for use with glassware, stainless-steel fixtures, silicon wafers, surgical instruments, and polymer-based labware (e.g., polycarbonate, PTFE, and polypropylene). It supports cleaning protocols aligned with ASTM F2476 (Standard Guide for Ultrasonic Cleaning Validation), USP (Cleaning and Sanitization of Equipment), and ISO 15883-4 (Washer-disinfectors – Part 4: Performance requirements and test methods for cleaning processes). All electrical components meet CE marking requirements under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU). The stainless-steel housing complies with FDA 21 CFR 178.3570 for indirect food contact surfaces.
Software & Data Management
While the base unit operates via front-panel digital controls, optional firmware upgrades enable audit-trail-capable logging (timestamped frequency, power %, duration, and thermal status) stored internally or exported via serial interface. When integrated with LabVantage or Thermo Fisher SampleManager LIMS, the system supports electronic batch records per FDA 21 CFR Part 11—requiring user authentication, electronic signatures, and immutable data retention for up to 12 months. All parameter changes are logged with operator ID and reason-for-change fields.
Applications
- Pre-sterilization cleaning of reusable surgical trays and endoscopic channels in hospital central sterile supply departments (CSSD).
- Residue removal from HPLC vials, autosampler needles, and chromatography columns in analytical QC laboratories.
- Surface activation and oxide layer removal prior to thin-film deposition in semiconductor R&D.
- Removal of polishing compounds and metal fines from machined aerospace components.
- Cell culture flask and bioreactor part cleaning under cGMP Annex 1 environmental controls.
FAQ
Can the KQ-2000ZB be used in flammable solvent baths?
No. This unit is rated for aqueous and water-miscible solvent systems only. Operation in hydrocarbon or alcohol-based solvents requires explosion-proof certification not provided with standard configuration.
Is calibration traceable to NIST or other national standards?
Power output calibration is performed using IEC 61000-4-30-compliant power analyzers; full metrological traceability documentation is available upon request for IQ/OQ validation packages.
What is the expected service life of the transducer under continuous operation?
Rated for 20,000 hours MTBF when operated within specified thermal and duty-cycle limits (≤80% duty cycle, ambient ≤35 °C, coolant flow ≥1.5 L/min if jacketed).
Does the system support automated start/stop via PLC input signals?
Yes—dry-contact trigger inputs (24 VDC) are available as an optional hardware module for synchronized operation with conveyor or robotic handling systems.
How is acoustic performance verified after installation?
Shumei provides aluminum foil erosion test protocols and calibrated hydrophone measurement services (optional) per ASTM E1002 for field validation of cavitation intensity distribution.
