NESCO builds wet suppression systems to control visible dust produced by mining and material handling operations. Our effective and affordable spray system equipment has become the industry standard for crushing and screening plants since we installed our first unit in 1989.

DustPro Spray Systems feature high (200psi) pressure operation, remote electronic control, and heavy-duty construction. DustPro pump modules are "state-of-the-art" and can be fully automated or equipped with air and glycol purge systems for cold weather operation. Guaranteed to comply with SubPart 000 or other applicable NSPS. Available in 10 to 100 gpm capacities.

The DustBoy is our most economical spray system and is designed for smaller crushing or recycle plants processing less than 500 tph. DustBoy pumps include a strainer, TEFC motor, and Nema 4X control panel. Available in 10 or 20 gpm capacities, manually controlled.

Our DirtSquirt Wheel Wash stops trucks from tracking mud onto public roads. The DirtSquirt includes a 160 gpm, high-pressure pump module, motion sensor, speed bump, and dual action spray bars. Fully automatic operation. No excavation required.

NESCO Air Atomizing Spray Systems use water and compressed air to produce micron sized droplets that are able to suppress respirable dust without adding any detectable moisture to the process. Ideal for spray curtains to contain dust within hoppers.

Fog Systems use ultra-high pressure and fine nozzle orifices to produce 10 micron droplets that humidify the environment and suppress dust and diesel exhaust in a confined area.

Wetting Agents are chemicals that are added to water to improve the rate at which spray droplets wet dust particles. NESCO doesn't sell chemicals but our DustPro and DustBoy spray systems can be modified to include a metering pump and in-line mixer to dispense a surfactant. Improves dust control on hard to wet materials like coal or petroleum coke.

NESCO can also build Foam Systems that use water, compressed air, and chemical agent to make a low-expansion foam that controls emissions from crushers and transfer points. Unlike chemical vendors that lock a customer into their chemical, NESCO equipment allows the customer to use less expensive generic chemicals.

Finally, NESCO sells all the Pumps, Parts, and Spray Nozzles to build spray systems from scratch. These are the same field-proven components we use to build our equipment. We keep a complete inventory of parts and are happy to provide technical assistance.
