NESCO Water Spray
$0.00
The Airtight NESCO Water Spray system delivers effective dust control for industrial sites by using high-pressure water spray to suppress airborne particulates at the source. Designed to add precise moisture levels to material handling zones, conveyors, stockpiles and transfer points, this solution reduces visible dust and downstream dust generation without over-wetting materials. NESCO Water Spray Systems are a cost-effective, reliable option for mining, waste, recycling, manufacturing and bulk materials operations seeking improved air quality, safety and regulatory compliance. With durable construction and targeted spray delivery, NESCO systems help you minimise fugitive dust emissions and support cleaner, safer industrial environments.

Description
NESCO Water Spray Dust Suppression System
Dust generated during crushing, conveying, stacking and bulk material handling can become airborne as material is moved and processed.
A NESCO water spray dust suppression system applies water around these dust-generating areas to help control dust before it spreads through the surrounding environment.
The system can be configured around the material being handled, dust source and site operating conditions.
Designed for Mining & Bulk Material Handling
- Mining crushing plants
- Stackers
- Quarries
- Aggregate plants
- Bulk material handling
Target Dust Where It Is Generated
Water spray systems can be useful where dust is generated across larger material handling and processing areas.
The appropriate spray arrangement should be designed around the material, process, dust source and available water supply, rather than simply applying more water to the process.

Controlled Water Application for Material Wetting
Sometimes it is desirable to wet process material through a direct application of water. DSI Water Spray Systems use a high-pressure pump and a variety of spray nozzles to add the right amount of water to your material. This type of system is used at locations from conveyor stack outs to storage piles, and in processes where slightly wetting the process material is not a problem. Some systems are equipped with modulating water regulators that are programmed to maintain the proper ratio of material process flow to water.
How Does NESCO Water Spray Dust Suppression Work?
NESCO spray systems control dust by producing a highly atomized mist that suppresses airborne particulates larger than 15um while adding from 0.2% to 0.5% moisture by weight to the process to prevent visible dust emissions from downstream unit operations. Water spray systems work on the principle of agglomeration for airborne dust, by producing water droplets that are the same size as the dust particles. These droplets collide with the dust particles and create larger particles that gravity brings back to the ground/process. The key component with water sprays is that the smallest droplet possible on a high pressure water spray system is around 20um, which will be effective for visible and inhalable dust, but not respirable airborne dust. The downstream reduction of dust created by the moisture addition will reduce the creation of respirable and visible dust.
NESCO Water Spray vs Other Dust Suppression Systems
Choosing the right dust suppression method depends on your material, process and site requirements. See how NESCO Water Spray Dust Suppression compares with DIY water sprays, dust collection systems and chemical dust suppression.
NESCO vs DIY water spray systems
Standard spray nozzles may produce larger or inconsistent droplets, which can lead to uneven material wetting and unnecessary water use.
NESCO uses high-pressure water, purpose-selected nozzles and controlled positioning to provide consistent dust suppression while managing moisture addition. Zone control can also help reduce unnecessary water consumption.
NESCO vs Dust Collection Systems
Dust extraction captures airborne dust and transports it through ductwork to a dust collector, where the collected material must then be discharged or managed.
NESCO suppresses dust at the material source using water, without requiring extraction ductwork or a separate dust collector. For suitable applications, this can provide a simpler dust-control approach with lower equipment and operating requirements.
NESCO vs Chemical Dust Suppression
Chemical systems use surfactants or other additives to improve wetting or help bind dust particles, creating an ongoing requirement for chemical supply, storage and handling.
NESCO uses high-pressure water atomisation to improve material wetting without chemical additives, avoiding the ongoing cost and handling requirements associated with dust-suppression chemicals.
