The Riveer Equipment Decontamination Wash System with High Pressure (EDWS-HP) was designed for remote cleaning and decontamination of military equipment in harsh desert environments. Made of a robust box frame construction and powder coated to last, the custom-built EDWS-HP trailer is completely self-contained and provides a low center of gravity for greater stability on rough terrain.

The EDWS-HP is simple to operate and maintain requiring minimal operator training. Our one-button GripStartTM feature brings the unit to life and shuts it down when the operator simply pulls the trigger on one of its two wash guns. Each gun comes with 100' of hose on easy-rewind reels and can sustain 5 gallons per minute at a whopping 3,000 PSI for fast and efficient decontamination and washing operations. 

A built-in air powered high-pressure foamer will cover the side of an M1 Abrams in less than a minute. The compressed air used in creating the foam doubles as a convenient hook-up for power tools in case you notice a loose screw while washing.

Grip Start logo EDWS-HP is simple to operate and maintain. Minimal operator training is needed with our GripStartTM system; one button starts and stops the unit, and auto-start and shutdown technology automates the pumping cycle to ensure minimum pump wear and reduce generator demand. No calibration is needed for this technology.

EDWS-HP operates on JP-8, other common aircraft fuels or diesel. It can be supplied with on-board or external supplies of water for continuous use when a clean water supply is available. Water can be held in a 525-gallon tank that allows for a lengthy run time when no water is nearby.

Another benefit of the system is its ability to be easily transported. It can be towed with HMMV, TUG, or other common AGE. It features a 6″ to 28″ tow bar height, surge brakes, stout and fully boxed trailer construction and a 7000# axle set rating. Baffles help to stabilize the tank by reducing the free-surface effect. EDWS-HP is transportable in accordance with MIL-STD-209, 1791, and 913.
