KUDOS SK-24E Heavy-Duty Floor-Standing LED Ultrasonic Cleaner

Overview

The KUDOS SK-24E is a heavy-duty, floor-standing ultrasonic cleaner engineered for laboratories, quality control facilities, and industrial maintenance departments requiring consistent, high-energy cleaning of large or high-volume components. Operating at a robust 25 kHz frequency, the unit leverages low-frequency cavitation physics—optimized for macro-scale particle removal and penetration into complex geometries—making it especially suitable for cleaning engine parts, surgical instruments, optical assemblies, printed circuit boards, and large-volume batches of glassware or metal fixtures. Its 90 L stainless steel tank (304 grade) supports immersion of oversized items up to 540 mm in length, while the dual-zone transducer array—comprising 24 precisely mounted piezoelectric elements—ensures uniform energy distribution across the entire bath volume. Unlike benchtop units, the SK-24E’s structural architecture integrates reinforced chassis, vibration-dampened feet, and thermal management systems to sustain continuous operation under load without resonance drift or thermal derating.

Key Features

• High-power ultrasonic output: 1000 W nominal power with fully continuous, digitally controlled amplitude modulation (40–100% in 1% increments), enabling precise process optimization for diverse substrates and soil types.
• Integrated digital temperature control: Maintains setpoint stability within ±1 °C across the full 20–60 °C range, critical for temperature-sensitive cleaning chemistries and enzymatic decontamination protocols.
• Extended programmable timer: 1–199 minute resolution supports both rapid degreasing cycles and extended soak-and-cavitate procedures, with automatic shutdown and audible alert.
• LED-illuminated tank chamber: High-lumen, cool-white LED array mounted beneath the lid provides shadow-free visual inspection during operation—enhancing operator safety and real-time process monitoring.
• Drain valve assembly: Front-mounted, quick-release brass valve with integrated filter screen enables safe, residue-free tank evacuation without disassembly.
• Compliance-ready construction: All wetted surfaces fabricated from electropolished 304 stainless steel; electrical enclosure meets IP22 ingress protection; CE-marked per EN 61000-6-3 (EMC) and EN 61000-6-2 (immunity).

Sample Compatibility & Compliance

The SK-24E accommodates a broad spectrum of sample types—including metallic, ceramic, polymer, and composite components—without compromising structural integrity or surface finish, provided compatible cleaning solutions are selected (e.g., aqueous alkaline, neutral pH, or mild acidic formulations). It is routinely deployed in ISO 13485-certified medical device manufacturing environments for pre-sterilization cleaning validation, and in automotive R&D labs for residual flux and particulate analysis per ASTM D2621 and ISO 8502-3. While not inherently validated for sterile processing, its reproducible energy delivery and traceable parameter logging (via optional RS232/USB interface) support IQ/OQ documentation under GLP and GMP frameworks. The unit complies with IEC 61000-3-2 harmonic current limits and conforms to RoHS 2011/65/EU material restrictions.

Software & Data Management

The SK-24E features an embedded microcontroller-based control system with non-volatile memory for storing up to 10 user-defined cleaning protocols—including frequency, power level, temperature setpoint, and duration. Optional connectivity (RS232 or USB-B) enables integration with laboratory information management systems (LIMS) or centralized equipment monitoring platforms. When paired with KUDOS’ optional PC software suite (v3.2+), users gain access to audit-trail-enabled operation logs, timestamped parameter change history, and exportable CSV reports compliant with FDA 21 CFR Part 11 requirements for electronic records and signatures. All firmware updates are delivered via signed binary packages with SHA-256 checksum verification.

Applications

• Precision cleaning of large-volume optical components (lenses, mirrors, laser cavities) prior to coating or metrology.
• Removal of machining oils, carbon deposits, and polishing compounds from aerospace turbine blades and fuel system parts.
• Bulk decontamination of reusable surgical trays, orthopedic implants, and endoscopic accessories in hospital central sterile supply departments (CSSD).
• Preparation of metallurgical samples for SEM/EDS analysis by eliminating embedded abrasive particles and lubricants.
• Supporting ASTM E1417 penetrant testing workflows through standardized pre-cleaning of test specimens.
• Electronics manufacturing: Cleaning PCBAs post-reflow to eliminate no-clean flux residues before conformal coating.

FAQ

Is the SK-24E suitable for cleaning delicate optics or MEMS devices?
Yes—when operated at reduced power (40–60%) and lower temperatures (25–35 °C) with low-surface-tension, non-ionic aqueous solutions, the 25 kHz frequency delivers sufficient cavitation intensity for contaminant removal without damaging micron-scale features.
Does the unit support remote monitoring or network integration?
Standard configuration includes RS232 serial output; Ethernet or Wi-Fi modules are available as factory-installed options for SCADA or Industry 4.0 integration.
Can the transducer array be serviced or replaced in-field?
Transducers are hermetically sealed and warrantied for 24 months; replacement requires certified technician service due to calibration-critical acoustic coupling alignment.
What safety certifications does the SK-24E hold?
CE, RoHS, and EMC compliance per EN 61000 series; electrical safety tested to EN 61010-1 for laboratory equipment; no UL listing unless ordered with North American voltage variant (120 VAC/60 Hz).
Is validation documentation provided for GxP environments?
Factory-supplied IQ/OQ templates and test protocols are included; full 3Q validation support (including PQ execution) is available through KUDOS Application Engineering Services upon request.
