Submersible Cavitation Rod 3000W 4-Side Immersible Ultrasonic Transducer Bar in Stainless Steel for Industrial Tank Cleaning 28kHz 40kHz

The 4-Sided Immersible Ultrasonic Transducer Bar is an industrial-grade sonication unit engineered for retrofitting existing process tanks and equipping multi-stage cleaning lines. Unlike standard single-surface immersible plates that project acoustic energy in only one direction, this hexagonal prism bar houses transducer arrays along four active radiation faces. This geometry generates an omnidirectional cavitation field throughout liquid baths, minimizing acoustic shadows and dead zones.

Each unit connects to an external digital ultrasonic generator equipped with automatic frequency tracking, continuous output power control, and internal thermal-protection circuitry.

Technical Specifications

Structural Design & Transducer Array Architecture

The housing utilizes a six-sided stainless steel profile. Four wider primary facets hold the transducer arrays, while the two narrower facets provide structural rigidity against hydrostatic pressure and mechanical stress.

Construction Features:

• Internal Transducer Array: High-efficiency piezoelectric ceramic elements are prestressed with high-tensile alloy bolts and bonded to the inner walls with aerospace-grade structural adhesive for stable acoustic transmission.
• Hermetic TIG Welds: End caps, suspension brackets, and housing seams undergo TIG argon-shielded welding followed by helium mass spectrometry or pressurized immersion leak tests.
• Armored Signal Delivery: High-frequency coaxial lines route through a sealed strain-relief gland inside a flexible stainless steel braided hose to shield cables against chemicals and physical abrasion.

Tank Integration & Mounting Configurations

The compact profile permits drop-in placement into cleaning, degreasing, pickling, and rinsing tanks without structural tank modifications.

Standard Installation Orientations:

1. Vertical Top-Hung Suspension: Suspended from rim brackets or crossbeams into deep process tanks.
2. Bottom-Floor Horizontal Mounting: Positioned along tank bottoms to drive acoustic energy upward through dense parts baskets.
3. Side-Wall Immersion: Secured along tank side walls horizontally or vertically to provide direct lateral cavitation across complex geometries.

Operational Rule: The ultrasonic bar must remain completely submerged in liquid during operation. Dry operation will cause rapid thermal overload and permanent damage to internal transducers.

Industrial & Sonochemical Applications

The high cavitation density generated along four faces supports industrial cleaning lines as well as sonochemical liquid processing.

• Heavy-Duty Degreasing (28 kHz): Removes baked-on grease, carbon deposits, scale, and heavy machining soils from engine blocks, castings, and heavy tooling.
• Precision Finishing (40 kHz): Cleans electronic parts, medical instruments, aerospace components, and precision optics without surface erosion.
• Liquid Defoaming & Degassing: Accelerates bubble coalescence and removes entrained gases from polymers, paints, resins, and liquid chemical mixtures.
• Dispersion, Emulsification & Extraction: Breaks agglomerated nanoparticles, homogenizes immiscible fluid phases, and improves botanical extraction yields in liquid processing vessels.

Engineering Customization Options

All units can be tailored to meet specific tank dimensions, chemical baths, and power requirements.

• Frequency: 28 kHz, 40 kHz, or custom single/dual frequencies.
• Power Capacity: Scalable configurations ranging from 600 W to 3600 W per assembly.
• Materials & Coatings: Standard SUS304 (2.0 mm), SUS316L (2.5 mm), hard-chrome plating (≥20 µm), or titanium alloy for aggressive chemical baths.
• Mounting Interfaces: Flange mounts (DIN/ANSI/Tri-Clamp), bottom mounting studs, or top suspension handles.

Quality Control & Testing Standards

Every transducer bar and generator undergoes rigorous verification prior to dispatch.

1. Acoustic Impedance Analysis: Verifies resonant frequency consistency and electrical impedance matching across all transducer channels.
2. Submerged Full-Load Burn-In: Continuous submerged testing under full power to confirm cavitation consistency and thermal stability.
3. High-Voltage Insulation Testing: Hi-Pot dielectric testing verifies insulation integrity between live circuits and the stainless steel casing.
4. Export-Standard Packaging: Units are packed in form-fitted high-density foam and heavy-duty wooden shipping crates to prevent transport shock.

International Compliance & Certification

Manufacturing processes and electrical components comply with international industrial safety directives.

• ISO 9001:2015: Certified quality management system for ultrasonic equipment production.
• CE Directive: Full compliance with EU Low Voltage (LVD) and Electromagnetic Compatibility (EMC) regulations.
• RoHS: Manufactured without restricted hazardous substances.
• Laboratory Audits: Verified via third-party CNAS-accredited performance and emission test reports.

Operating Precautions & Maintenance

• Liquid Level: Liquid must always cover the entire active transducer section by at least 50 mm before powering on the generator.
• Workpiece Clearance: Maintain a minimum distance of 20 mm between workpieces/baskets and the transducer bar surface to avoid acoustic dampening and localized cavitation pitting.
• Thermal Cycling: For continuous multi-shift operations, include an intermittent pause (≥3 minutes) after extended cycles to dissipate internal heat.
• Chemical Bath Guidelines: Formulated for water-soluble neutral, mild alkaline, or mild acidic cleaning agents. Do not use concentrated strong acids or alkalis unless the bar is customized with SUS316L or titanium.
• Generator Protection: Install the generator console in a dry, ventilated area away from steam, splash zones, and corrosive fumes.
