Ultrasonic Cleaner

The Cleaning Foundation of Every Jewellery Showroom, Factory & Gem Lab

Every piece of jewellery a customer hands across a showroom counter, every finished ring leaving a factory QC desk, every diamond before it reaches the certification microscope, and every prong-setting just out of the laser welder needs to be cleaned — and clean here doesn't mean "wiped with a cloth." It means deep-crevice removal of microscopic dirt, skin oils, polishing compound residue, plating-solution traces, and the embedded film that builds up inside ring pavé settings, around prongs, inside chain links, between watch components, and across every micro-feature of finished jewellery that a brush, cloth, or hand-cleaning method cannot reach. The only machine that does this job in 3–10 minutes without scratching the metal, abrading the platings, or chemically damaging gemstones is the ultrasonic cleaner. The Semsons Tech Ultrasonic Cleaner is the precision cleaning machine engineered exactly for this demand — 40kHz piezoelectric cavitation technology, SUS304 stainless-steel tank and basket, adjustable heater up to 80°C, digital timer with auto-shutoff, sandwich-type transducers ensuring even cavitation across the full tank volume, and the workhorse reliability that runs daily 8-hour shifts across years of professional use.

For 48 years, Semsons Tech has supplied ultrasonic cleaners to the Indian and international jewellery trade. Every cleaner we ship is factory-tested for transducer output, heater performance, and timer accuracy — trusted across retail jewellery showrooms in every Indian state, jewellery manufacturing factories in Mumbai/Surat/Rajkot/Coimbatore/Jaipur, Bharat Diamond Bourse Mumbai merchants, Surat polishing factories, lab-grown diamond manufacturers, gemological certification laboratories (IGI, IIG, regional labs), watchmakers, dental labs, casting houses, polishing houses, plating shops, hallmarking centres, and the international jewellery trade across UAE Dubai Gold Souk, Saudi Arabia, Bangkok, Hong Kong, Antwerp, and 34+ other markets. Available in capacities from 0.6L compact to 30L heavy-duty industrial — plus authorised supply of premium imported brands including Crest, Branson, Elma, and VEVOR.

Core Engineering Advantages

• 40kHz Piezoelectric Cavitation Technology: The industry-standard jewellery cleaning frequency. Generates 40,000 cycles per second of microscopic vacuum-bubble formation and collapse (cavitation) — each bubble collapse releases a tiny jet of energy that scrubs the deepest crevices, prong undersides, chain link interiors, and engraved details that no brush or hand-cleaning method can reach. Optimal balance between cleaning aggression and gentleness on delicate platings and gemstone settings.

• Dual-Frequency 28/40kHz Option: Premium configuration with operator-toggle between aggressive 28kHz mode (casting plaster removal, heavy polishing compound, post-investment cleaning) and gentle 40kHz mode (finished jewellery, delicate platings, mounted gemstones). One machine handles every cleaning task from raw casting output to certification-grade finished pieces.

• SUS304 Stainless-Steel Tank Construction: Ultrasonic-grade SUS304 stainless steel — corrosion-immune across years of daily use with detergents, pickling solutions, alkaline pre-plating solutions, and acidic cleaning chemicals. The same material grade used in laboratory, medical, and food-processing applications.

• Sandwich-Type Piezoelectric Transducers: Dual transducers on 2–6L units, triple on 9.5–15L units, multi-transducer arrays on 20–30L industrial units — ensures even cavitation distribution and eliminates "dead zones" inside the tank where items would otherwise emerge partially cleaned. Critical for production-line consistency.

• Adjustable Heater up to 80°C: Built-in heater raises the bath temperature to accelerate cavitation action — at 60–80°C, dissolving grease, wax, polishing compound, and embedded oils in minutes rather than the half-hour required at room temperature. Digital temperature display with precise setting control.

• Wide Voltage Tolerance (180V–250V AC): Operates reliably across Indian retail and factory power conditions including the voltage fluctuations and brownouts common in Tier-2 and Tier-3 city electrical supply. Survives surges that would damage commodity-grade cleaners.

• Digital LED Timer (0–30 minutes) with Auto-Shutoff: Precise 1-minute increment time setting prevents over-cleaning (which can loosen stones from settings and damage delicate platings) while saving operator time across multi-batch daily workflow. Auto-shutoff protects against unattended over-cycling.

• Stainless Steel Lid & Anti-Vibration Feet: SUS304 lid retains heat, prevents chemical evaporation and splashing, and contains ultrasonic noise (a real concern in customer-facing retail showroom environments). Anti-vibration feet keep the unit stable on retail counters and workbenches during operation.

• Drain Valve on 6L+ Units: Built-in tank drain valve enables easy solution changes between cleaning tasks (gold detergent → degreaser → alkaline pre-plating) without manual tipping. Essential for multi-process operations switching solutions multiple times daily.

• Stainless Steel Basket Included: Holds delicate items off the transducer floor (where direct contact can damage mounted gemstones and concentrate cavitation energy). Standard accessory across all configurations.

• Indicator LEDs: Power / Heater / Ultrasonic / Timer status indicators provide at-a-glance operator awareness — essential for busy retail counters and production-line workflow.

• Programmable Multi-Cycle Option: Premium configurations include preset cleaning programs by piece type (gold finished / silver jewellery / casting plaster removal / polishing compound / pre-plating degreasing) — eliminates operator-error in production-line settings and standardises cleaning quality across operator changes.

Technical Specifications

How an Ultrasonic Cleaner Works — The Science of Cavitation

An ultrasonic cleaner generates high-frequency sound waves (typically 40kHz — 40,000 cycles per second) inside a water-and-detergent bath using piezoelectric transducers mounted on the tank floor. These sound waves create millions of microscopic vacuum bubbles in the liquid — a phenomenon called cavitation. When each bubble collapses, it releases a tiny jet of energy that scrubs the surface of any item submerged in the bath — including the deepest crevices, prong undersides, chain-link interiors, and engraved details that no brush, cloth, or hand-cleaning method can reach. With the built-in heater raising the bath to 40–80°C, the cavitation action accelerates dramatically, dissolving grease, wax, polishing compound, and embedded oils in minutes rather than the hour or more required by hand-cleaning. This is why every serious jewellery business — retail or manufacturing — runs an ultrasonic cleaner: it does in 5 minutes what hand-cleaning cannot do in an hour, without scratching the metal, loosening stones, or damaging delicate platings. For 28kHz dual-frequency configurations, the lower frequency creates larger, more aggressive cavitation bubbles — ideal for casting plaster removal and heavy contamination; the 40kHz mode delivers gentler cleaning suitable for finished jewellery with delicate prong settings and mounted gemstones.

Capacity Selection — Choosing the Right Tank Size

• 0.6L / 0.75L Compact — for boutique designer studios, single-bench jewellers, and gem labs cleaning individual stones before grading. Sits on a small bench corner without dominating space.
• 1.3L / 2L Bench-Top — for small retail showrooms, gemmologist workstations, and home jewellery cleaning services. The most popular entry-level configuration for new retail showrooms.
• 2.85L / 3L Standard — the workhorse retail showroom configuration. Cleans a tray of rings, chains, or earrings in a single load. The default choice for most independent jewellery retailers.
• 4.5L / 6L Mid-Range — for multi-counter showrooms, jewellery repair shops, and small manufacturing units. Accommodates larger pieces like bangles, statement necklaces, and bridal sets.
• 6.5L / 9.5L / 10L Production — for jewellery factory finishing rooms, casting houses (post-investment), and high-volume retail chains. Handles dozens of pieces per cycle in batch-processing workflow.
• 15L Industrial — for casting factories, polishing houses, and high-throughput manufacturing operations running multi-shift daily production.
• 20L / 30L Heavy-Duty Industrial — for large jewellery manufacturers, watch factories, dental labs, and combined precious-metal recovery operations. Multi-transducer arrays ensure consistent cavitation across the large tank volume.
