450W 28kHz 40kHz SUS304 Immersion Ultrasonic Vibration Transducer Rod 500mm Immersible Cavitation Bar for Emulsion Extraction Cleaning

The GH0950 immersible ultrasonic transducer rod delivers 360-degree radial acoustic energy directly into process tanks. Built for new equipment builds and retrofit installations, the cylindrical design replaces conventional box-style transducer plates in confined or irregularly shaped reservoirs.

The internal array consists of 9 industrial-grade piezoelectric transducers sealed within heavy-gauge stainless steel. Powered by a separate-excitation digital generator with manual power adjustment, the GH0950 provides steady cavitation for heavy-duty degreasing, liquid defoaming, homogenization, and sonochemical extraction.

Technical Specifications

Key Engineering Features

• Radial 360-Degree Acoustic Radiation: Distributes cavitation energy evenly around the entire circumference of the rod, eliminating acoustic blind zones.
• Separate-Excitation Digital Generator: Automatically locks operating frequency to tank load, fluid temperature, and bath level.
• Corrosion-Resistant Housing: Constructed standard with 2.0 mm wall-thickness SUS304. Optional SUS316 (2.5 mm) and titanium resist aggressive chemical baths.
• Integrated Mounting Flange: Welded industrial flange allows fast mechanical insertion and positive liquid-tight sealing.

Installation Orientations

The cylindrical profile allows installation in tight spaces where standard immersion transducer boxes do not fit:

• Top-Mounted Suspension: The rod hangs vertically from the top rim or lid of the tank. Best suited for open cleaning baths and vertical part transfer lines.
• Bottom-Mounted Insertion: The rod installs vertically through the base of the tank via a flange connection. Directs cavitation energy upward throughout the liquid column.
• Side-Mounted Horizontal Insertion: The rod penetrates the side wall of the tank horizontally. Recommended for shallow tanks, continuous pipe flow-through setups, and multi-stage immersion lines.

Operational Requirement: The transducer rod must remain completely submerged in liquid during operation. Dry startup causes irreversible transducer failure.

Primary Industrial Applications

1. Parts Cleaning and Degreasing

• 28 kHz: Generates high-energy cavitation bubbles that release intense mechanical shockwaves upon collapse. Designed for heavy grease, scale, flux, and carbon residue on cast iron, steel tooling, engine blocks, and machinery parts.
• 40 kHz: Produces finer cavitation bubbles with higher population density. Designed for precision components, electronics, PCBs, optical lenses, and medical instruments without causing surface cavitation erosion.

2. Liquid Degassing and Defoaming

Ultrasonic cavitation forces micro-bubbles dissolved in liquids to coalesce into larger bubbles that float to the surface. Used in paint preparation, varnish manufacturing, beverage bottling lines, and resin processing.

3. Emulsification and Sonochemical Dispersion

Replaces mechanical shear blades for liquid-liquid and liquid-solid processing. Cavitation disrupts droplet boundaries and breaks particle agglomerates, producing stable nano-emulsions, uniform pigment slurries, and faster botanical extraction rates.

Quality Control and Packaging Standards

• Transducer Matching: Piezoelectric ceramics undergo impedance analysis and static capacitance sorting prior to assembly.
• Hermetic Weld Verification: Cylindrical tubes and mounting flanges undergo automated argon-arc welding followed by structural pressure testing.
• Immersion Burn-In Test: Every completed assembly undergoes a 4-hour continuous burn-in water test under full load to verify frequency and thermal stability.
• Export Packaging: Transducer rods ship in custom reinforced wooden crates to prevent bending during transport. Generators ship in heavy-duty corrugated cartons with high-density foam padding.

Manufacturer Profile and OEM Capabilities

Granbo Technology Industrial Shenzhen Co., Ltd. has developed and manufactured industrial ultrasonic equipment since 2013, supported by an engineering team with over 20 years of sector experience.

Our facility manufactures benchtop ultrasonic cleaners, industrial immersion systems, and automated cleaning lines. We supply global distributors and industrial end-users with full OEM/ODM services, including custom rod dimensions, dual-frequency transducers, custom flange specifications, and private labeling.

Certifications and Compliance

All equipment conforms to international safety and electromagnetic directives:

• Quality Management: ISO 9001:2015 Registered
• European Conformity: CE Certified (EMC Directive & LVD Directive)
• Environmental Safety: RoHS Compliant
• Electromagnetic Compatibility: FCC Certified

Operational Precautions

• Fluid Level: Liquid must fully cover the active length of the rod before powering on the generator. Dry operation is strictly prohibited.
• Workpiece Spacing: Maintain a minimum distance of 2 mm between parts and the tube surface to preserve ultrasonic transmission and avoid tube wear.
• Chemical Compatibility: Use only mild, water-soluble detergents with standard SUS304 rods. For operations with strong acids or alkalis, select SUS316 or titanium metallurgy.
• Duty Cycle Management: The hardware supports extended duty cycles. After extended continuous operation, allow an intermittent cooling pause (3 minutes or longer) if fluid circulation is absent.
• Generator Protection: Keep the generator unit dry and away from chemical fumes, splash zones, and corrosive atmospheres.
• Input Voltage: Confirm input voltage before connection. Available configurations include: 220V EU, 220V UK, 220V AU, 110V US, 220V US, and 220V JP.

Customization and Ordering Steps

1. Define Tank Dimensions: Provide tank length, width, liquid height, and chemistry.
2. Select Parameters: Choose frequency (28 kHz or 40 kHz), rod length, rod diameter (50 mm or 60 mm), and tube material (SUS304, SUS316, or Titanium).
3. Engineering Review: Receive and approve dimensional flange drawings and generator load calculations.
4. Fabrication and Shipping: Production completes with full burn-in testing before dispatch via air freight, ocean carrier, or international express.
