Dual Orifice Swirl Nozzle - Advanced Dual-Stream Atomization Technology for Precision Misting Applications
The Dual Orifice Swirl Nozzle represents Jinsheng Mist's innovative engineering approach to dual-stream water atomization, featuring two independent swirl chambers that produce parallel mist streams within a single nozzle body. This precision-machined fitting creates consistent, uniform mist patterns with droplet sizes ranging from 5–20 microns at operating pressures of 50–70 bar, making it ideal for applications requiring wider coverage or dual-direction misting without additional piping. Designed for industrial dust control, commercial cooling, and specialized landscape fogging, this dual-orifice nozzle delivers enhanced coverage efficiency and installation flexibility across demanding misting systems worldwide.
Dual-Stream Swirl Design
Our twin-orifice atomizing nozzle utilizes two parallel swirl chambers:
Independent Swirl Chambers: Two separate internal swirl paths create parallel mist streams
Adjustable Spray Angles: Each orifice can be configured for different spray patterns (30° to 90°)
Synchronized Flow: Balanced pressure distribution ensures uniform output from both orifices
Interchangeable Orifice Inserts: Replaceable swirl inserts for maintenance or pattern changes
Premium Material Construction
The dual-port swirl sprayer is manufactured from high-grade materials:
304/316L Stainless Steel: Maximum corrosion resistance for harsh outdoor and industrial environments
Ceramic Insert Option: Enhanced durability for abrasive water conditions
Ruby Orifice Available: Ultra-premium option for continuous industrial operation
UV-Resistant Housing: Suitable for prolonged outdoor exposure
Versatile Configuration Options
Equal Orifice: Both ports same diameter for symmetric spray patterns
Reducing Orifice: Different port sizes for varied flow rates per stream
Adjustable Angle: Rotatable orifice inserts allow custom spray direction
Standard Threaded Connections: M5, M6, 1/8", 1/4" for easy installation
Precision Engineering
Tight Tolerance Machining: Ensures consistent flow balance between both orifices
Smooth Internal Flow Paths: Minimizes pressure drop and turbulence
Anti-Clog Architecture: Self-flushing design reduces blockage frequency
Burst Pressure Rating: Tested to 150+ bar for safety margin
-
Enhanced Coverage Efficiency
- Dual-Stream Output: Two mist streams cover wider area than single-orifice nozzles
- Reduced Nozzle Count: Fewer nozzles needed for equivalent coverage
- Uniform Distribution: Balanced flow ensures consistent mist density across both streams
- Flexible Positioning: Single installation point serves two coverage zones
-
Superior Atomization Quality
- Droplet Size: 5–20 microns for effective evaporation without surface wetting
- Consistent Spray Pattern: Uniform mist density across entire dual-stream coverage
- Controlled Spray Trajectory: Minimizes drift and unwanted water dispersion
- Instant Fog Effect: Creates immediate visible mist upon activation
-
Cost-Effective Installation
- Reduced Component Count: Fewer nozzles, fittings, and pipe runs required
- Lower Labor Costs: Faster installation with fewer mounting points
- Simplified Piping: Single feed line serves dual output streams
- Minimal Maintenance: Two streams from one nozzle means fewer components to service
-
Long-Term Reliability
- Corrosion Resistance: Premium materials withstand harsh environments
- Wear Resistance: Distributed flow reduces wear on individual orifice components
- Temperature Tolerance: Stable performance from -20℃ to 80℃
- Extended Service Life: 10,000+ hours (standard), 20,000+ hours (ruby orifice)
