DiSCS Digital Spray System

DiSCS Digital Spray System

Mega's DiSCS system is designed to promote water conservation and safety by providing adjustable, automated spray applications. DiSCS can be installed on any off-highway water distribution equipment. Mega also offers kits to upgrade older DiSCS systems to the most current version.

DiSCS utilizes CAN Bus technology to operate all spray control system components. DiSCS uses the integrated Mega GPS to automatically regulate the amount of water spray applied relative to vehicle ground speed or distance traveled.

The DiSCS spray system includes the following standard features. Specifications may vary by model. For additional information, please contact our Equipment Sales, Parts Sales or Product Support Teams.

The control integration kit provides the electrical harnesses necessary to control chassis and Mega-provided components. The kit also includes standoffs, LED work lights, mounting and connection hardware. Tractor integration interface components are sold separately.

The Mega hydraulic hose kit provides all necessary hose and fittings to connect the DiSCS system to the hydraulic oil supply and valves. Additional fittings may be required for some prime movers.

GPS provides ground-speed data for several spray application modes.

 

GPS Based Sensing
The GPS system is universal and does not require application-specific engineering. Unlike radar-based systems, the Mega GPS system is not vulnerable to environmental contamination.

 

Self-Contained
GPS eliminates the need for connections to other vehicle systems to determine speed, making it easy to adapt to a wide variety of machine applications.

 

Automated Water Conservation
GPS data allows the DiSCS system to use a pulsing strategy to automatically manage the amount of water consumed while effectively controlling dust.

 

Automatic Shut-Off
GPS information allows the DiSCS system to automatically shut off the flow of water as the vehicle comes to a stop to prevent puddling. Spraying resumes automatically as the vehicle accelerates.

This kit includes a mounting pedestal and installation hardware. Pedestals may be adjustable or fixed depending on the truck model. Installation may require slight modifications to console panels and fabrication of an adapter bracket.

Mega's DiSCS operator controls include a water cannon joystick, built-in water level indicator and electrical harnesses. The control system supports all available spray control functions.

Distance-Based Spraying (Checkerboard)
Alternating intermittent watering patterns reduces water consumption and ensures one steering tire and one drive tire remain on a dry surface.

 

Speed-Based Spraying (Continous Coverage)
Sequence-based intermittent spray system operation uses PWM (Pulse Width Modulation) to vary the amount of water flow while maintaining a continuous rate of water application, independent of speed.

 

Time Based Spraying (Banding)
Operator adjustable, full width, intermittent wet/dry pattern.

 

Manual Spraying
The system can be operated manually independent of GPS signal.

The DiSCS solenoid control box is a stainless steel, weather resistant, sealed enclosure built to withstand the harshest environments found in mining and construction. Features of our Genuine Mega control box include:

Consolidated hydraulic system with centralized solenoid and wiring assemblies provides easy access to coils and spools.


Externally-mounted filter which provides protection for the hydraulic control valves.


Easily accessible logic control module for programming and diagnostics.


Durable wiring harness with Deutsch® connections and fuse protection. Harness includes pre-wired functions
for easy plug-and-play of additional functions.

Mega provides a complete set of technical manuals detailing installation, operation, maintenance, inspection and replacement parts. Additional manuals are available for purchase. Visit our Technical Manuals Page for more information.

Kit includes weld-on boss, water level sensor, communication cable and mounting hardware.

Mega's proprietary spray control software provides protections to extend the service life of your water pump.



Soft Start/Stop
Controlled starts and stops increase the service life of the drive motor and water pump.

 

Low Water Shut-Off
When low water level is sensed, automatic soft stop prevents dry running of the water pump.

 

No Flow Shut-Off
When extended pump operation is detected with all valves closed, automatic soft stop prevents damage to the water pump from overheating.

Your DiSCS® spray system can be configured with these optional features. Availability and specifications may vary by model. For additional information, please contact our Equipment Sales, Parts Sales or Product Support Teams.

Mega's severe-duty butterfly valves are designed for dependable operation. Valves are available in three and four inch diameters for use with dump bars, as well as four and eight inch diameters for use with drain applications.

The Mega foam agent system provides an effective fire suppression solution for construction and mining environments. The foam agent tanks are available in 60, 120 and 200 gallon capacities and are designed to be mounted externally on top of the water tank. The foam agent system includes a reservoir with sight gauges, mounting brackets and hardware, supply hose, shut-off valve, and ground-level fill. Water cannon and foam nozzle are sold separately.

Mega hose reel kits include hose reel and hose, nozzle, supply valve, feed nipple, mounting plate and hardware. Available hose reels options include:
