• Compatible with all OEM articulated truck chassis, 25T to 60T
• Combination baffling system features baffle valves in both transverse and longitudinal directions, mitigating liquid surge to avoid rollovers and provide superior stability, braking performance, and operator comfort
• Logic control system offers intuitive in-cab operation. Access all functions inside the cab instead of having to engage hydraulics, open valves and then open spray heads
• Safety features like spray heads automatically close whenever the truck ignition is switched off
• Manually adjust flow settings, all by controls in the cab: 
  • choose a flow rate of 320, 480, or 630 GPM
    (gallons per minute). 
  • Dial in water pressure between 40 and 100 PSI
• Customizable water tank systems with several optional add-ons

Only the best will do for these vital components of the Hydex water tank system and that's why we chose Elkhart — known for the best on the market. Controlled by a joystick inside the cab, the water cannon shoots up to 170-feet (AWT5, AWT6) or 213-feet (AWT8, AWT9, AWT13). Hard-to-reach areas across mines, quarries and construction sites, are no longer a concern.

Fully adjustable, heavy duty, double-acting hydraulic actuated spray heads

Centrifugal water pump, mounted in an easily accessible location, driven from the truck's hydraulic system to ensure optimum performance.

Hydex tanks are engineered for rugged performance and praised for customization and flexibility. Innovative features and the advanced baffling system enhance productivity and safety. Hydex's superior spray system design delivers uniform water distribution and minimal water wastage thanks to high-quality clog-resistant nozzles.

The commitment to quality extends beyond the product. That's why Hydex chose Hills Machinery — to provide the same level of craftsmanship in product and customer support. The Hills team will help guide water tank system configuration and customization; coordinate a seamless installation and beneficial product training; follow up on performance and product satisfaction; proactively manage preventative maintenance and more.
