SHUMEI KQ-1500VDE Triple-Frequency Digital Ultrasonic Cleaner

Overview

The SHUMEI KQ-1500VDE is a high-capacity, triple-frequency digital ultrasonic cleaner engineered for demanding laboratory, industrial quality control, and precision component cleaning applications. It operates on the principle of cavitation—where controlled acoustic energy at ultrasonic frequencies generates microscopic implosions in the cleaning medium, effectively dislodging particulate contaminants, organic residues, and thin oxide layers from complex geometries without mechanical abrasion. Its tri-band frequency capability (45 kHz, 80 kHz, and 100 kHz) enables selective optimization: lower frequencies deliver higher cavitation intensity for robust removal of heavy particulates or machining oils; mid-range frequencies balance penetration and gentleness for general-purpose parts; while the 100 kHz mode offers finer, more uniform energy distribution suited for delicate optics, microfluidic devices, and MEMS components. With a 112-liter stainless steel tank constructed entirely from ASTM A240 304-grade material, the system supports batch processing of large assemblies, glassware sets, or multi-tiered fixtures under fully programmable conditions.

Key Features

• Triple-frequency ultrasonic generation (45 / 80 / 100 kHz) with user-defined switching intervals (0–999 seconds), allowing dynamic adaptation to multi-step cleaning protocols.
• Digital microcontroller-based operation with real-time display of ultrasonic power (%), selected frequency, temperature setpoint vs. actual bath temperature, elapsed time, and fluid level status.
• Adjustable ultrasonic power output (40–100% of 1500 W nominal) and independent heating control (6000 W, ambient to 80 °C) enable precise thermal–acoustic coupling for enhanced soil solubilization.
• Integrated safety architecture includes automatic shutdown upon low liquid level detection, over-temperature, over-voltage, over-current, and dry-run conditions—fully compliant with IEC 61000-6-2/6-4 electromagnetic compatibility standards.
• Electrically actuated fill and drain valves support unattended operation and integration into semi-automated workflows; noise-reduction lid minimizes airborne sound pressure levels to ≤65 dB(A) at 1 m distance.
• Full 304 stainless steel construction (tank, chamber, and structural frame) ensures corrosion resistance in aqueous, alkaline, and mild solvent-based cleaning solutions.

Sample Compatibility & Compliance

The KQ-1500VDE accommodates a broad range of sample types—including metal alloys (stainless steel, aluminum, titanium), borosilicate glassware, ceramic substrates, silicon wafers, and polymer-based medical device components—provided they are compatible with aqueous or low-volatility cleaning chemistries. Its operational parameters align with common laboratory validation frameworks: temperature and time settings support ISO 13485-compliant cleaning process qualification, while digital parameter logging (via optional RS485 or USB interface) facilitates adherence to GLP and GMP documentation requirements. Though not intrinsically rated for hazardous location use, its electrical design conforms to GB/T 14710 (Chinese national standard for environmental adaptability of medical electrical equipment) and meets CE marking essential requirements for laboratory equipment safety (EN 61010-1:2010 + A1:2019).

Software & Data Management

While the KQ-1500VDE features an embedded single-board controller rather than PC-hosted software, its firmware supports non-volatile memory storage of up to 10 user-defined cleaning programs—including frequency sequence, power level, temperature ramp profile, dwell times, and fill/drain timing. All parameter changes are timestamped and retained across power cycles. Optional communication modules (RS485 Modbus RTU or USB-to-serial) allow integration with LabVantage, STARLIMS, or custom SCADA systems for centralized monitoring, audit-trail generation, and electronic batch record (EBR) compliance per FDA 21 CFR Part 11 when paired with appropriate validation packages and user access controls.

Applications

• Pre-analytical sample preparation: cleaning HPLC vials, autosampler trays, and ICP-MS nebulizer components to minimize trace metal carryover.
• Medical device manufacturing: final rinse and debris removal from surgical instruments, endoscopic channels, and implant packaging molds.
• Electronics manufacturing: flux residue removal from PCB assemblies prior to conformal coating or AOI inspection.
• Materials research labs: surface decontamination of catalyst supports, battery electrode foils, and nanomaterial substrates prior to XRD or SEM analysis.
• Optics and photonics facilities: particulate-free cleaning of laser lenses, interferometer mirrors, and fiber optic ferrules without micro-scratching.

FAQ

Is the KQ-1500VDE suitable for use with flammable solvents?
No. The unit is designed exclusively for aqueous or water-miscible, non-flammable cleaning solutions. Its heating element and electronics are not explosion-proof.
Can frequency switching be programmed to occur automatically during a single cycle?
Yes. The interval between frequency transitions is adjustable from 0 to 999 seconds, enabling fully automated multi-stage cleaning sequences.
What is the warranty coverage and service support structure?
SHUMEI provides a 24-month limited warranty covering parts and labor for defects in materials and workmanship, with technical support available via email and remote diagnostics.
Does the system include data export capability for regulatory audits?
Standard configuration includes digital parameter logging; optional serial communication modules enable CSV export of operational logs for inclusion in audit-ready documentation packages.
How is tank volume calibrated and verified for GLP compliance?
Volume calibration is performed using NIST-traceable graduated cylinders during factory acceptance testing; users may perform periodic verification using certified volumetric measures per SOP-QC-017.
