BTW-20 to BTW-40
These compact models cover about 20 m to 45 m still-air range and usually fit enclosed points, transfer areas, smaller yards, or projects where lighter power demand and smaller footprint matter first.
Long-range fog cannons
Custom-built long-range fog cannons for industrial dust suppression
Long-range fog cannons are configured for industrial dust-suppression projects where spray distance, water route, installation form, control logic, and climate conditions must match the real site.
Long-range fog cannons for wide-area industrial dust control
This product family is commonly used where dust needs to be controlled across open yards, stockpiles, transfer areas, and semi-enclosed industrial sheds. Typical projects include coal yards, ports, steel plants, mines, and coking facilities.
- Spray range can be matched to smaller transfer points, general yard work, or large stockyard coverage
- Adjustable pitch and rotation help one machine follow changing dust points more effectively
- Control options can include local buttons, wireless remote control, PLC, and central monitoring
- Installation can be matched as fixed tower, ground-mounted, trailer, or vehicle-integrated

Model Families
Three model brackets to compare first
Once the basic working principle is clear, the next step is to match the spray range to the dust-control area before selecting the pump, nozzle, and control details.
BTW-50 to BTW-70
This middle bracket covers about 50 m to 75 m and is often the practical range for general steel-yard, coking, mining, or shed dust-suppression work where spray width and operating stability must stay balanced.
BTW-80 to BTW-150
These large-yard models cover about 80 m to 150 m, typically with larger dual-ring nozzle layouts, heavier fan power, and soft-start or variable-frequency logic for ports, large coal yards, and wide-span industrial sheds.

Selection note: Ultra-fine packages can use plunger, centrifugal, or metering-pump routes according to atomization demand; motors above 18.5 kW are usually matched with soft start or variable-frequency start; and actual water makeup is often only part of total spray volume when the site uses recirculated water.
Installation Methods
Three installation methods for different sites
Installation has a major impact on fog cannon pricing, almost as much as spray range. A fixed unit, a mobile unit, and a truck-mounted unit may share the same atomization principle but still require different structure, utilities, and control packages.
Fixed
For coal sheds, steel plants, ports, and long-term fixed points
Suitable for sites with stable spray direction and long-term continuous operation. The unit can be matched with foundation work, reserved water supply, and reserved electrical connection.
- Typical fit: enclosed coal sheds, steel yards, ports, large stockyards
- Useful when repeatable spray angle and long-term stability matter most
- Often paired with remote control, PLC, or central monitoring
Mobile
For temporary sites or areas without convenient water and power
Available as towable, hand-pushed, or unmanned remote-control layouts. Water tanks, generators, and other complete-unit configurations can be integrated according to site conditions.
- Typical fit: coal yards, mines, coking plants, ports, thermal-power areas
- Can be planned as fixed-base, towable, or frequently moved work points
- Often selected when range bracket and spray width come first
Truck-mounted
For projects that require mobile dust suppression
Suitable for temporary dust-suppression tasks that require fast transfer. The fog cannon can be integrated onto a truck, engineering vehicle, or dedicated chassis for movement between multiple work points.
- Typical fit: road dust suppression, temporary work areas, mobile industrial support
- May require generator, battery, or hydraulic drive matching
- Useful when one machine must serve several work zones
Pump Configuration Selection
Three common pump solutions and application scenarios
The pump affects atomization performance, spray pressure, and maintenance method.
Vortex pump
Compact structure with simple maintenance, suitable for standard dust-suppression scenarios where space is limited, budget matters, and ultra-fine atomization is not a strict requirement.
Plunger pump
Higher pressure and finer atomization, suitable for high-pressure spraying, ultra-fine mist requirements, or projects without stable pipeline water supply that need self-priming capability.
Stainless multistage centrifugal pump
A stable and lower-noise route for projects with reliable pipeline water supply, especially where corrosion resistance and smooth running matter.
Nozzle Ring Configuration Selection
Three common nozzle ring solutions and application scenarios
Nozzle ring quantity and structure determine mist density and coverage range, so they should be selected according to the fog cannon model, spray range, and working conditions.
Single-ring nozzle layout
The single-ring route is the common economical structure. It is straightforward, easy to match, and suitable for standard dust-suppression work where nozzle quantity does not need to be very high.
- Best for: standard projects and budget-sensitive layouts
- Advantage: simple, proven, and cost-effective
- Limitation: nozzle quantity is more limited than dual-ring layouts
Dual-ring nozzle layout
Dual-ring layouts allow more nozzles and more flexible matching of nozzle quantity and diameter, which is why they are common on large-yard and longer-range machines.
- Best for: wider spray area and larger machines
- Advantage: more nozzle density and flexible atomization setup
- Extra option: center-nozzle routes can be added for longer throw
Three-ring nozzle layout
Three-ring layouts provide more nozzles and finer mist delivery, making them suitable for projects that want denser spray coverage and more flexible atomization tuning.
- Best for: projects with higher mist density needs
- Advantage: more nozzles and stronger atomization flexibility
- Often selected when spray uniformity matters more than basic layout simplicity
Control & Optional Configuration
Starting control and motion mechanisms, selected as needed
After the core fog cannon solution is confirmed, motion packages, control cabinets, anti-freeze components, and low-noise components can be selected according to power supply, control needs, installation method, and climate conditions.
| Starting method | Typical fit | What it changes |
|---|---|---|
| Direct start | Usually for small motors up to about 11 kW | Lowest cost and compact cabinet layout, but higher inrush current and higher grid impact during startup. |
| Star-delta start | Common mid-level route for projects that want a simpler cost structure than soft start | Reduces startup shock compared with direct start while keeping the control structure relatively familiar and economical. |
| Soft start | Usually recommended once fan power moves into larger-machine territory, especially above 18.5 kW | Provides gentler startup, lower grid shock, and protection functions such as phase loss, overload, and overtemperature. |
| Variable-frequency start | For projects that need softer startup, speed adjustment, and more flexible control logic | Allows frequency and speed adjustment, which helps larger models coordinate startup, spray behavior, and low-noise operating strategies. |
PLC Cabinet
Motor, pump, interlock, and monitoring in one cabinet
The PLC cabinet integrates motor protection, pump control, interlock protection, and remote monitoring for centralized automation.

The control system can support multi-terminal operation with real-time feedback for pressure, temperature, and fault status.
- Local buttons, remote control, mobile access, or computer monitoring
- Status feedback for safer operation and easier troubleshooting
Hydraulic Power Unit
Precise pitch and rotation control
The motion system is selected according to equipment size and site load, using a hydraulic cylinder or electric pushrod as needed.
- Matched to fog cannon specification and working load
- Supports stable elevation and rotation adjustment
Winter & Low Noise
Anti-freeze and low-noise packages for site conditions
Anti-freeze and noise-reduction options can be selected according to climate conditions and environmental requirements.
- Anti-freeze options: heating, heat tracing, and drainage
- Low-noise options: structural details and lower-speed operation

Product FAQ
Common questions before final model confirmation
How do we choose the right fog cannon model if we only know the site size and required range?
That is usually enough for the first step. We normally start with the required still-air distance, the size of the dust area, the dust source, and whether the site is open or enclosed. From there we can narrow the range bracket first and then discuss pump type, nozzle ring, and installation form.
Are the 12 models fixed catalog machines or can they still be customized?
The table is a reference family, not a hard limit. We can still customize color, logo, voltage and frequency, range direction, pump route, control method, installation layout, winter package, and other details according to the project brief. MOQ is 1 unit.
Which pump should we choose: vortex, plunger, or centrifugal?
If the site needs self-priming or finer atomization, the plunger route is usually the stronger option. If the site has stable pipeline water and prefers smoother, lower-noise running, a stainless multistage centrifugal pump is often a better fit. Vortex pumps are commonly chosen when space and maintenance simplicity matter more than maximum pressure.
What is the actual water use, and can the system work with recirculated water?
Water use depends on the selected model, which is why the table lists standard and ultra-fine flow for each machine. In recirculated-water projects, actual water makeup can be only about 10 to 20 percent of total spray volume, because much of the water can be collected and reused depending on the site design.
Does installation require complex commissioning?
Not usually. We test the machine before shipment, so site work is mainly focused on fixing the unit in position and connecting water and power. Fixed tower units still need suitable civil base work and electrical connection, while mobile or truck-integrated layouts are usually faster to bring into operation.
What can the control system actually do, and how far can remote control reach?
Available functions can include start and stop, pitch and rotation control, pump and fan switching, and operating-status feedback such as pressure, temperature, and alarm signals. Open-area wireless remote control is usually 100 meters or more, with 200-meter and 2-kilometer options available. Mobile-app and computer monitoring depend on network support.
How are cold-climate and low-noise requirements handled?
For winter use, we can add heated nozzle or pipe routes, steam or electric tracing, and automatic drain functions. For low-noise projects, larger models can use lower fan speed, sawtooth outlet silencing that reduces high-frequency noise by about 3 to 4 dB, and sandwich acoustic structure that can reduce noise by about 5 to 10 dB.
What lead time, warranty, and support should we expect?
Standard fog cannon models usually require 15 to 20 working days after order confirmation. Customized versions such as explosion-proof, cold-climate, or special-voltage units usually require 30 to 45 days depending on configuration complexity. The whole-machine warranty is 18 months, major components follow the same 18-month period, and two years of spare parts are shipped with the order.
RFQ Checklist
Useful inputs for faster model selection
These are the details that usually help us move from a broad inquiry to a narrower model and configuration recommendation.
- Open yard, enclosed shed, transfer point, or road-spraying use
- Required spray distance and approximate coverage width
- Tower, ground base, towable, or truck-mounted layout idea
- Pipeline water supply, self-priming need, or recirculated water condition
- Voltage, frequency, and whether soft start or VFD is preferred
- Remote control, PLC, winter package, explosion-proof, or low-noise requirements
Quick tip: Site drawings, layout sketches, and phone photos usually shorten the model-selection process more than a generic “please quote one fog cannon” request.
