Shumei KQ-1000ZB Immersion Ultrasonic Transducer Plate

Overview

The Shumei KQ-1000ZB Immersion Ultrasonic Transducer Plate is an industrial-grade, modular ultrasonic energy delivery system engineered for integration into custom cleaning tanks, passivation baths, solvent degreasing stations, and inline process lines. Unlike benchtop ultrasonic cleaners, this immersion-type transducer plate operates on the principle of piezoelectric resonance—converting high-frequency electrical signals (28 kHz or 40 kHz) into mechanical vibrations transmitted directly into liquid media via a rigid 316L stainless steel radiating surface. Its design follows the fundamental physics of cavitation threshold optimization: at these frequencies, microbubble nucleation and implosive collapse generate localized pressures exceeding 1000 atm and transient temperatures above 5000 K—enabling efficient removal of particulate contaminants, organic residues, oxides, and biofilms from complex geometries, blind holes, and microfluidic channels. The unit is not a standalone cleaner but a core subsystem intended for OEM integration or retrofitting into existing tank infrastructure, complying with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards for laboratory and light-industrial environments.

Key Features

• Full 316L stainless steel construction—resistant to nitric acid, citric acid, alkaline solutions, and organic solvents across pH 1–14 and temperatures up to 40 °C.
• High-Q piezoceramic transducers with optimized electromechanical coupling coefficient (k_t ≥ 0.48), ensuring >85% electroacoustic conversion efficiency under rated load conditions.
• Digital generator with auto-sweep, real-time frequency tracking, and adaptive impedance matching—maintains resonant operation despite fluid level fluctuations, temperature drift, or fouling-induced acoustic loading changes.
• Triple-parameter LED display showing instantaneous ultrasonic frequency (kHz), output current (A), and elapsed time (s)—enabling traceable process validation per GLP/GMP requirements.
• Programmable power output (0–100% in 1% increments) and timer (0–9999 s in 1-s resolution), supporting repeatable multi-step cleaning protocols.
• Integrated thermal sensor with automatic shutdown if internal generator temperature exceeds 75 °C; continuous thermal monitoring logged internally for maintenance diagnostics.
• Standard isolated remote control interface (0–10 V analog or dry-contact TTL) plus optional RS-485 Modbus RTU support for SCADA integration and centralized fleet management.

Sample Compatibility & Compliance

The KQ-1000ZB is compatible with aqueous, semi-aqueous, and low-viscosity organic solvents (e.g., isopropanol, ethanol, acetone, terpenes) within the specified temperature range (0–40 °C). It supports cleaning of metallic substrates (stainless steel, aluminum, titanium), silicon wafers, glassware, ceramic components, and polymer assemblies—including medical device parts compliant with ISO 13485. The system meets essential safety and electromagnetic compatibility requirements per IEC 61010-1 (electrical safety for laboratory equipment) and IEC 61326-1 (EMC for measurement/control equipment). While not certified to UL/CSA or CE for standalone use, it satisfies component-level conformity when integrated into final equipment meeting full regulatory obligations (e.g., FDA 21 CFR Part 820, ISO 14644 cleanroom validation support).

Software & Data Management

The embedded controller provides deterministic real-time operation without reliance on external software. All operational parameters—including start time, duration, power setpoint, frequency mode, and thermal history—are stored in non-volatile memory with timestamping. Optional RS-485 connectivity enables bidirectional communication using Modbus RTU protocol (function codes 03h/06h/10h), allowing integration with LIMS or MES platforms for electronic batch records. Audit trails comply with ALCOA+ principles: attributable, legible, contemporaneous, original, accurate, complete, consistent, enduring, and available—supporting FDA 21 CFR Part 11 readiness when paired with validated host software.

Applications

• Pre-sterilization cleaning of surgical instruments and endoscopes in hospital central sterile supply departments (CSSD).
• Removal of polishing compounds and oxide layers from precision machined aerospace components prior to coating or inspection.
• Decontamination of chromatography columns, HPLC vials, and electrophoresis apparatus in analytical laboratories.
• In-line cleaning of MEMS sensors, semiconductor wafer carriers, and photomask handling tools in Class 100–1000 cleanrooms.
• Passivation bath agitation for stainless steel pharmaceutical piping systems (per ASTM A967 / ISO 16048).
• Supporting USP particulate matter testing by enabling reproducible rinse-step debridement of filter membranes and syringe barrels.

FAQ

Is the KQ-1000ZB suitable for use with flammable solvents?
No. It is rated for use only with non-flammable or low-flashpoint solvents operated below their autoignition temperature and within closed, ventilated systems meeting NFPA 30 and ATEX Zone 2 guidelines.
Can multiple KQ-1000ZB units be synchronized in one tank?
Yes—via the RS-485 interface with master-slave configuration; phase alignment ensures uniform cavitation distribution without destructive interference.
What is the expected service life of the transducer under continuous duty?
Rated for ≥20,000 hours MTBF when operated within specifications and maintained per Shumei’s quarterly inspection protocol (including visual inspection of bonding integrity and impedance verification).
Does the unit support programmable multi-stage cleaning cycles?
Not natively—the timer is single-stage—but external PLC or PID controller integration via the analog/digital I/O interface enables full sequence automation.
Is calibration documentation provided with shipment?
Yes: each unit ships with a factory calibration certificate (traceable to NIM, China) verifying frequency accuracy (±0.2 kHz), power linearity (±3% FS), and thermal cutoff repeatability (±2 °C).
