Immersion Ultrasonic Vibration Transducer Rod 900W 28kHz 40kHz 950mm Rod Length SUS304 Immersible Sonicator Tube for Tank Cleaning

360-Degree Radial Cavitation for Process Tanks, Chemical Dispersion, Defoaming, and Industrial Cleaning

The GH1895 cylindrical immersion transducer rod delivers uniform radial ultrasonic energy for installation into existing industrial tanks, reaction vessels, and pipe systems. Standard flat transducer plates emit acoustic energy in a single axial direction; by contrast, this cylindrical configuration emits cavitation continuously across a full 360-degree perimeter.

The complete system includes a 950 mm hermetically sealed stainless steel vibration rod containing 18 industrial-grade piezoelectric transducers, powered by an external separate-excitation digital generator. The digital controller provides manual power regulation, sweep frequency operation, pulse mode, and degassing functions to accommodate specific liquid processing requirements.

Technical Specifications

Vessel Integration and Mounting Configurations

The integrated mounting flange enables rigid, fluid-tight installation directly through tank openings without structural vessel modifications:

• Top-Mount Installation: Suspended vertically through a tank lid or upper frame into the liquid bath. Ideal for open immersion tanks, parts cleaning lines, and batch reaction vessels.
• Bottom-Mount Installation: Flange-mounted through the base plate of the reservoir. Acoustic energy radiates upward through the liquid column to prevent acoustic dead zones at the tank floor.
• Side-Mount Installation: Inserted horizontally through the vessel sidewall or an inline fluid pipe. Suited for deep reservoirs, recirculating liquid systems, and continuous inline flow reactors.

Crucial Operating Requirement: The entire active rod length must remain fully submerged in liquid before applying power. Dry operation causes immediate thermal damage to the internal piezoelectric transducer stack.

Application Engineering & Frequency Selection

1. Frequency Selection Guide

• 28 kHz (60 mm Rod Diameter): Heavy-Duty Decontamination
  Generates larger cavitation bubbles that release high mechanical impact force upon collapse. Intended for removing heavy grease, drawing lubricants, carbon scale, oxide layers, and rust from engine blocks, casting parts, and heavy tooling.
• 40 kHz (50 mm Rod Diameter): Precision Cleaning & Liquid Processing
  Produces higher bubble density with moderate collapse energy. Recommended for precision machined parts, optical components, printed circuit boards, and laboratory processing.

2. Liquid Degassing and Defoaming

High-frequency alternating pressure fields force micro-bubbles suspended in viscous fluids to coalesce into larger buoyancy bubbles that rise out of the medium. This process eliminates entrained air in coatings, inks, paints, resin polymers, and food emulsions without requiring chemical additives.

3. Dispersion, Emulsification, and Extraction

Acoustic cavitation generates intense localized shear forces, breaking apart solid particle agglomerates, blending immiscible liquids into stable emulsions, and accelerating cellular disruption for botanical and chemical extraction lines.

Quality Control and Manufacturing Standards

• Piezoelectric Transducer Matching: Each transducer element undergoes frequency and impedance testing before assembly to guarantee electrical uniformity across all 18 elements.
• Hermetic Weld Integrity: Automated TIG welding seals the tube body and mounting flange. Assemblies undergo pressure and submersion leak testing to eliminate the risk of liquid ingress during operation.
• Full-Load Burn-in Testing: Finished transducer rods undergo continuous submerged burn-in testing under full load to confirm output stability and generator frequency tracking.
• Export Packaging: Transducer rods are packed in reinforced export wooden cases to prevent shaft deflection during transport. Generators are housed in shock-absorbing foam-lined corrugated cartons.

Certification and Operating Precautions

Compliance

• Quality Management: Certified under ISO 9001:2015
• Electrical Safety and EMC: CE Certified
• Hazardous Substances: RoHS Compliant
• Electromagnetic Compatibility: FCC Certified

Operating Guidelines

• Fluid Level: The active rod surface must remain fully covered by fluid during operation; dry startup is prohibited.
• Workpiece Spacing: Maintain a minimum distance of 2 mm between workpieces and the vibrating tube surface to ensure uniform cavitation and prevent surface wear.
• Detergent Compatibility: Standard SUS304 stainless steel is compatible with neutral or mildly alkaline water-soluble cleaning solutions. Strong acids or strong alkalis require optional SUS316 or titanium construction.
• Duty Cycle Management: The system supports long continuous operation cycles. When running continuously at high power, implement an intermittent pause (at least 3 minutes) to avoid thermal overload.
• Generator Placement: Keep the separate-excitation generator housing away from moisture, acid mist, and direct fluid spray.
