Supmile KQ-A2000GKDE High-Power Temperature-Controlled Digital Ultrasonic Cleaner

Overview

The Supmile KQ-A2000GKDE is a floor-standing, high-power, temperature-stabilized digital ultrasonic cleaner engineered for laboratories and industrial quality control environments requiring precise thermal management during ultrasonic processing. Unlike standard ultrasonic cleaners that rely solely on resistive heating, the KQ-A2000GKDE integrates a hermetically sealed, non-CFC refrigeration compressor alongside high-capacity heating elements—enabling active dual-mode thermal regulation. This architecture maintains solution temperature within ±0.5 °C across the full 0–80 °C operating range, critical for applications sensitive to thermal drift, such as enzymatic digestion, solvent-based extraction, or polymer dissolution where reaction kinetics are temperature-dependent. The unit operates at a fixed 40 kHz frequency—a balance between cavitation intensity and uniform energy distribution—optimized for cleaning precision components, optical substrates, and porous medical devices without surface erosion.

Key Features

• Floor-standing robust stainless-steel chassis (304 grade) with reinforced base for vibration isolation and long-term stability in high-throughput labs
• 112 L capacity tank (700 × 400 × 400 mm internal dimensions) constructed from seamless, electropolished 304 stainless steel for corrosion resistance and cleanability
• Dual thermal control system: 6000 W heating element + 1400 W refrigeration compressor enables rapid temperature ramping and tight stabilization (±0.5 °C)
• Digitally adjustable ultrasonic power output (40–100% of 2000 W nominal), allowing optimization for delicate samples (e.g., microfluidic chips) or heavy particulate loading (e.g., metal machining residues)
• Programmable timer (1–480 minutes) with automatic shutdown and audible end-of-cycle alert
• Integrated sound-dampening lid with ergonomic lift-assist mechanism reduces ambient noise to ≤65 dB(A) at 1 m distance, meeting ISO 11201 occupational safety guidelines
• Manual inlet/outlet valves with level-sensing capability (adjustable fill range: 10–30 cm depth) support solvent recovery protocols and closed-loop rinsing workflows

Sample Compatibility & Compliance

The KQ-A2000GKDE accommodates a broad spectrum of sample formats—including glassware (vials, flasks, cuvettes), metallic parts (surgical instruments, aerospace components), ceramic substrates, and polymer-based assemblies—without compromising structural integrity or surface finish. Its sealed refrigeration loop eliminates refrigerant leakage risks, conforming to EU F-Gas Regulation (EU) No 517/2014. All electrical components meet IEC 61010-1:2010 safety standards for laboratory equipment. While not certified for sterile processing per ISO 13485, the unit supports GLP-compliant documentation when paired with external audit-ready data loggers (e.g., compliant with FDA 21 CFR Part 11 when used with validated software interfaces).

Software & Data Management

This model features an embedded digital controller with LED touchscreen interface supporting multi-step program storage (up to 10 user-defined protocols). Real-time display shows current temperature, elapsed time, power level, and system status (heating/refrigeration active). Optional RS-485 or USB-to-serial interface enables integration with Lab Information Management Systems (LIMS) for automated parameter logging and electronic batch records. Data export is compatible with CSV format for traceability in regulated environments; audit trail functionality requires external validation per GxP requirements.

Applications

• Pre-analytical sample preparation: removal of organic residues from HPLC vials, GC autosampler trays, and ICP-MS nebulizer components
• Medical device reprocessing: cleaning of endoscopic channels, orthopedic implants, and dental handpieces prior to sterilization validation (per AAMI ST91)
• Materials science: dispersion of nanomaterials (e.g., graphene oxide, metal oxides) in aqueous or organic media under controlled thermal conditions
• Pharmaceutical R&D: solvent-assisted extraction of botanical actives, tablet coating residue removal from punch tooling, and dissolution vessel cleaning per USP <701>
• Electronics manufacturing: flux residue removal from PCB assemblies and semiconductor wafer carriers without thermal shock

FAQ

Does the KQ-A2000GKDE support continuous operation at 80 °C?
Yes—the refrigeration and heating subsystems are thermally decoupled and independently controlled, enabling sustained operation at maximum setpoint without thermal runaway or compressor overload.

Can deionized water be used as the cleaning medium?
Yes; however, prolonged use of low-conductivity solvents may reduce cavitation efficiency. For optimal performance, conductivity should exceed 100 µS/cm—addition of 0.1% w/v sodium carbonate is recommended for DI water applications.

Is the unit compatible with flammable solvents?
No. The KQ-A2000GKDE is not explosion-proof and must only be operated with non-flammable, non-halogenated solvents (e.g., aqueous detergents, ethanol/water mixtures below 40% v/v, or terpenes meeting ASTM D4306 flash point criteria).

What maintenance is required for the refrigeration system?
Annual inspection of refrigerant charge and condenser coil cleanliness is advised. No routine oil changes are needed—the hermetic compressor uses sealed lubrication per ISO 8573-1 Class 2 air purity standards.

How is temperature uniformity verified across the tank volume?
Supmile provides a calibration certificate documenting three-point (top/mid/bottom) temperature mapping at 25 °C, 45 °C, and 65 °C using NIST-traceable PT100 probes. Users may replicate verification using ASTM E2251-20 Annex A1 procedures.
