Overview
The Shumei KQ-AS2000VDE is a high-capacity, triple-frequency digital ultrasonic cleaner engineered for demanding laboratory, R&D, and industrial quality control environments. It operates on the principle of cavitation-induced acoustic energy transfer—generating microscopic implosions in liquid media when subjected to high-frequency sound waves. Unlike single-frequency systems, its three discrete operating frequencies (45 kHz, 80 kHz, and 100 kHz) enable selective optimization for diverse contaminant types and substrate geometries: lower frequencies deliver higher cavitation intensity for robust particulate removal from machined metals or ceramics, while higher frequencies provide finer resolution for delicate optics, microelectronics, or MEMS components without surface erosion. The unit features a 160 L stainless steel tank (800 × 500 × 400 mm internal dimensions), rated for continuous operation under controlled thermal and acoustic load conditions. Its 2000 W total transducer output is distributed across a uniformly coupled array of 304 stainless steel–housed piezoelectric elements, ensuring spatially consistent energy distribution and long-term stability.
Key Features
- Triple-frequency capability (45 / 80 / 100 kHz) with programmable frequency-switching intervals (0–999 s), enabling multi-stage cleaning protocols for complex soiling profiles.
- Digital microcontroller-based interface with real-time display of ultrasonic power (%), selected frequency, frequency dwell time, bath temperature (setpoint and actual), elapsed time, and fluid level status.
- Integrated safety architecture: automatic shutdown triggered by low liquid level, overtemperature (>80 °C), overcurrent, overvoltage, or dry-run conditions; visual and audible fault indicators.
- Electrically actuated sound-dampening lid with interlocked safety switch—meets IEC 61000-3-2 harmonic emission standards and reduces ambient noise to ≤65 dB(A) at 1 m distance.
- Electrically controlled fill-and-drain system with level-sensing solenoid valves, supporting automated batch processing and integration into semi-automated lab workflows.
- 304 stainless steel construction throughout wetted and structural components—including tank, transducer housing, and lid—ensuring corrosion resistance and compliance with ISO 15190:2020 laboratory equipment material requirements.
- 9 kW heating system with PID-controlled thermoregulation (±0.5 °C accuracy within 20–80 °C range) and independent calibration offset adjustment.
Sample Compatibility & Compliance
The KQ-AS2000VDE accommodates a broad spectrum of sample types—including metal parts, glassware, ceramic substrates, printed circuit boards, surgical instruments, and reusable analytical components—without requiring tooling or fixturing. Its large tank volume supports immersion of oversized assemblies (e.g., flow cells, reactor vessels, or multi-well plates on custom racks). All operational parameters are traceable and repeatable per GLP and GMP-aligned documentation practices. While not certified to FDA 21 CFR Part 11 out-of-the-box, the system’s parameter logging function (with timestamped event records stored in non-volatile memory) provides foundational data integrity for audit readiness. It conforms to IEC 61010-1:2010 for electrical safety and EN 60529 IPX1-rated enclosure protection.
Software & Data Management
The embedded firmware supports manual and sequence-based operation via front-panel keypad and LCD. Up to 10 user-defined cleaning programs can be saved, each containing up to five sequential steps with independent settings for frequency, power, duration, temperature, and frequency transition delay. Event logs—including start/stop timestamps, fault codes, and parameter deviations—are retained for ≥10,000 cycles and exportable via RS-232 interface (optional USB-to-serial adapter). No proprietary software installation is required; raw log files are compatible with standard spreadsheet and LIMS import formats. Audit trail functionality includes operator ID input (via alphanumeric entry), change history for all modified parameters, and immutable record timestamps synchronized to internal RTC.
Applications
- Pre-analytical sample preparation: removal of organic residues, polishing compounds, or solder flux from HPLC columns, GC injectors, and spectrophotometer cuvettes.
- Medical device reprocessing: cleaning of endoscopic accessories, orthopedic implants, and dental handpieces prior to sterilization validation per ISO 15883 and AAMI ST91.
- Materials science labs: deburring of additive-manufactured metal parts, descaling of heat exchanger coupons, and particle removal from wafer carriers.
- Quality assurance workflows: verification of cleaning efficacy using ATP bioluminescence or gravimetric residue analysis per ASTM D7247-16.
- Electronics manufacturing: post-reflow cleaning of PCBAs, removal of no-clean flux residues, and preparation of RF/microwave components for impedance testing.
FAQ
Is the KQ-AS2000VDE suitable for use with flammable solvents?
No. The unit is designed exclusively for aqueous or water-miscible detergent solutions. Use with flammable liquids violates IEC 60079-0 explosion-protection requirements and voids the warranty.
Can frequency switching be synchronized with temperature ramping?
Yes—within a single stored program, users may define cascaded steps where frequency, power, temperature, and time are independently assigned per stage.
What maintenance is required for long-term reliability?
Transducer coupling integrity should be verified annually via impedance spectroscopy; tank gasket replacement is recommended every 36 months under continuous use; filtration cartridge (included) requires cleaning after every 200 operating hours.
Does the system support external trigger inputs for automation integration?
Yes—the rear panel includes isolated TTL-compatible START/STOP and FAULT signal terminals compatible with PLC or SCADA systems.
Is calibration documentation provided with shipment?
A factory-issued Certificate of Conformance (CoC) is included, listing as-tested values for temperature accuracy, timer deviation, and power output linearity at 100% setting. NIST-traceable calibration services are available upon request.
