300W 28kHz 40kHz Immersible Ultrasonic Transducer Plate SUS304 Stainless Steel 6 Transducers Submersible Pack with Digital Generator

Industrial Immersible Ultrasonic Transducer Plates

Modular Ultrasonic Packs for Retrofit Tanks, Industrial Degreasing, and Sonochemical Processing

Immersible ultrasonic transducer plates convert existing fluid tanks, rinse stations, and processing vessels into high-efficiency ultrasonic systems. Instead of replacing installed machinery, users can lower or bolt these hermetically sealed transducer packs directly into place.

Each unit features an array of heavy-duty 50 W piezoelectric transducers bonded to thick stainless steel plates and driven by an external separate-excitation digital generator. The system provides linear power adjustment, stable resonance tracking, and continuous cavitation for industrial parts washing, surface finishing, liquid degassing, extraction, and chemical dispersion.

Technical Specifications

Process Tank Integration

Modular immersion plates allow multi-zone installation inside large volume vats. Transducers can be positioned along tank sidewalls and floor surfaces simultaneously to build balanced acoustic fields in complex vessels. This layout ensures cavitation energy penetrates nested components, dense basket arrangements, and large fabricated assemblies without directional shadowing.

Mounting Configurations

Transducer plates adapt to six core physical orientations inside processing vessels:

• Bottom Mounting (Base-Facing Upward): Placed along the tank floor to emit energy vertically through the liquid column. Suited for heavy parts baskets, degreasing, and particle settling.
• Side Mounting (Single Wall): Mounted along one wall to preserve tank floor clearance for sludge drainage and sediment collection.
• Opposed Dual-Side Mounting (Facing Walls): Units face inward from opposite tank walls to concentrate cavitation across the central processing zone.
• Top Mounting (Suspended Downward): Suspended from the tank rim to radiate downward into shallow baths or surface-floating media.
• Over-the-Rim Cable Routing: Conduit extends upward over the open tank rim, avoiding wall penetrations in existing tanks.
• Through-Wall Submerged Entry: Conduit passes through sealed wall fittings for closed, covered, or pressurized tanks.

Conduit and Cable Egress Options

To ensure fluid-tight integrity across various vessel designs, four conduit connections are available:

1. Rigid Pipe Conduit (Hard Tube): Fixed stainless steel pipe curved over the tank wall, functioning as both an electrical chase and a structural mounting hook.
2. Flexible Armored Conduit (Soft Tube): Braided stainless steel protective hose providing flexible routing around tank baffles, pipework, and structural framing.
3. Submerged Bulkhead Lock Nut (Immersion Lock Nut): Threaded compression fitting through the tank sidewall, providing a leak-tight mechanical seal for covered vessels.
4. Bottom Feedthrough Fitting (Bottom Lock Nut): Direct base penetration for installations where cables must exit beneath the vessel skirt.

Frequency Selection & Functional Applications

1. Frequency Selection

• 28 kHz (Heavy-Duty Cleaning & Degreasing): Produces larger cavitation bubbles that release high mechanical impact upon implosion. Recommended for removing heavy grease, thick oils, carbon build-up, scale, and rust from engine blocks, tooling, and heavy metal fabrications.
• 40 kHz (General-Purpose & Precision Cleaning): Delivers a higher bubble density with moderate collapse pressure. Ideal for precision machined components, circuit assemblies, optical parts, laboratory ware, and thin-gauge metals.

2. Process Applications

• Degreasing & Rust Removal: Dislodges bonded contaminants from blind holes, internal channels, and fine threads.
• Liquid Defoaming & Degassing: Merges entrained micro-bubbles into buoyant macro-bubbles, expelling trapped air from inks, coatings, polymers, and epoxy resins.
• Emulsification & Dispersion: Breaks down particle agglomerates and stabilizes immiscible liquids without excessive shear degradation.
• Botanical Extraction & Dissolution: Disrupts cellular walls in sonochemical extraction lines to accelerate active compound release.

Manufacturing Standards & Assembly

• Matched Piezoelectric Arrays: Transducer elements are individually tested and frequency-matched to ensure uniform load distribution across every 50 W horn.
• Precision TIG Welding: Robotic welding produces hermetic seams along all housing joints to prevent liquid ingress under continuous hydrostatic pressure.
• Reinforced Radiating Surfaces: Fabricated from 2.0 mm SUS304 or 2.5 mm SUS316 plate stock to resist cavitation erosion and extend service life.
• Pre-Shipment Burn-In: Completed assemblies undergo submerged electrical testing and resonance validation before pack-out.

Packaging and Transport Protection

• Transducer Plates: Sealed in moisture-resistant protective film, cushioned with high-density foam buffers, and secured in heavy-duty export wooden crates.
• Digital Generators: Packed separately in impact-resistant, thickened corrugated export cartons with custom foam inserts.

Quality Certification & Operating Guidelines

Quality & Safety Compliance

• Quality Management: ISO 9001:2015 Registered
• International Standards: CE Certified, FCC Compliant, RoHS Compliant
• Inspection Protocol: Full factory inspection and conformity verification on all electrical modules

Mandatory Operating Guidelines

• Submersion: Transducer plates must remain fully submerged during operation. Dry start-up causes thermal shock and permanently damages the piezoelectric transducers.
• Part Clearance: Maintain a gap of at least 2 mm between workpieces and the plate face to prevent premature surface wear and uneven acoustic distribution.
• Chemical Compatibility: Use mild, water-soluble detergents with standard SUS304 units. Strong acids or concentrated alkalis require SUS316, hard chrome plating, or titanium construction.
• Thermal Dissipation: After prolonged continuous operation under heavy load, pause operation for at least 3 minutes to permit internal heat dissipation.
• Generator Environment: House the external generator in a dry, ventilated area protected from moisture and chemical vapours.
