4-Side Radiating Immersion Ultrasonic Transducer Bar 900W 28kHz 40kHz SUS304 Tube with Digital Generator for Tank Extraction and Cleaning

The GHQ1845 Submersible Ultrasonic Transducer Rod delivers radial acoustic cavitation for industrial cleaning, liquid degassing, defoaming, and sonochemical processing. Engineered for integration into new or existing processing tanks, this immersion unit installs directly into vessels without requiring modifications to existing tank structures.

Technical Specifications

Frequency Selection

• 28 kHz: Low frequency with high cavitation intensity, suited for heavy-duty cleaning, thick grease, rust, and carbon deposits.
• 40 kHz: Standard frequency producing dense cavitation bubbles, suited for general-purpose cleaning, fine parts, precision instruments, and blind holes.

Structural Fabrication & Custom Engineering

Each probe contains an array of 18 pre-stressed piezoelectric transducers mounted inside a heavy-gauge stainless steel casing. The multi-sided layout radiates intense multi-directional ultrasonic energy outward throughout the liquid medium.

Custom configurations support various tank depths and processing conditions:

• Profiles: Hexagonal, square, and cylindrical housings.
• Mounting Interfaces: Top suspension hooks, mounting collars, welded flanges, and rigid conduit risers.
• Cable Protection: Stainless steel braided hose or high-durability flexible conduit.

Applications

• Ultrasonic Degassing & Defoaming: Coalesces and extracts trapped micro-bubbles from viscous liquids, epoxy resins, coatings, inks, and liquid food products.
• Dispersion & Emulsification: Breaks down particulate agglomerates, disperses pigments, and homogenizes immiscible liquids.
• Precision & Heavy-Duty Cleaning: Cleans machined metal components, engine blocks, hydraulic valves, surgical tools, and filtration assemblies.
• Sonochemical Extraction: Enhances mass transfer rates for botanical extraction and chemical synthesis.

Installation & Mounting Methods

Transducer units adapt to diverse tank layouts and liquid levels.

Standard Rod Mounting Orientations

1. Top-Mount (Suspended): Lowered vertically into the center or perimeter of the tank using top hanger brackets or rigid conduit risers.
2. Bottom-Mount (Upright): Anchored vertically from the tank floor for tall, narrow cleaning vessels.
3. Side-Mount (Horizontal): Mounted horizontally along the lower tank sidewall to deliver uniform acoustic distribution beneath submerged parts.

Pack & Transducer Conduit Configurations

• Over-the-Rim Conduit: Fluid-tight conduit bends up and over the tank lip, avoiding tank wall penetrations.
• Through-Wall Bulkhead: Rigid pipe exits directly through a sealed port on the tank side or base for a low-profile installation.

Quality Control & Certifications

Each unit undergoes multi-stage factory verification, including transducer impedance matching, insulation resistance testing, generator frequency calibration, and helium/submersion pressure leak checks.

Manufacturing processes comply with recognized international standards:

• ISO 9001:2015 Quality Management System Certification
• CE Marking (EMC and Low Voltage Directives)
• RoHS Environmental Compliance
• FCC Part 15 Verification

Operational Guidelines

• Submersion Requirement: The vibrating probe must remain fully submerged in liquid during operation. Dry operation causes prompt transducer overheating and irreversible damage.
• Workpiece Clearance: Maintain a minimum distance of 2 mm between items and the transducer surface to ensure sound propagation and prevent contact wear.
• Chemical Selection: Use neutral or mild water-soluble cleaning agents. Do not use strong acids or concentrated alkalis unless equipped with an SUS316 housing.
• Duty Cycle & Cooling: For continuous industrial operations, include intermittent pauses (≥ 3 minutes) during prolonged runs to prevent heat buildup.
• Generator Placement: Position the digital generator in a dry, ventilated environment away from liquid splashes and vapor.
