Back Room Equipment
"The heart of your operation lies in the backroom. Our advanced equipment suite features industrial high-pressure pump stands, precision-calibrated low-pressure chemical delivery systems, and high-output Reverse Osmosis (RO) units for a guaranteed spot-free finish. For the ultimate in control, our proprietary Smart Pressure Systems optimize water and energy usage in real-time.
Pressure Systems

HIGH PRESSURE
Whether you are designing a new bay or upgrading an existing setup, a high-pressure system is the heart of a self-serve car wash. To ensure reliability under constant stop-start cycles, the integration of industrial-grade components is essential.
-
5 HP Electric Motor: The workhorse of the system. A 5 horsepower motor provides the necessary torque to maintain consistent pressure (typically between 1,000 and 1,500 PSI) even during peak usage. These are usually high-efficiency, totally enclosed fan-cooled (TEFC) motors to withstand the humid car wash environment.
-
AR (Annovi Reverberi) Pump: Renowned for durability in the car wash industry, AR plunger pumps feature ceramic pistons and forged brass manifolds. They are designed for high-heat tolerance and long service life, ensuring that the "high pressure" in your high-pressure wax or rinse remains steady.
-
Metered Dosing Pump: Accuracy is key to profitability and cleaning quality. A metered pump ensures the exact ratio of chemical concentrate (soap, wax, or tire cleaner) is injected into the water stream. This prevents chemical waste and ensures a consistent experience for every customer.
-
Stainless Steel Solenoid Valves: Unlike brass, stainless steel valves offer superior resistance to the corrosive chemicals often found in car wash soaps and pre-soaks. These valves respond instantly to the user's selection on the bay meter, directing the flow of water and chemicals without leaking or sticking.

LOW PRESSURE
This system utilizes an advanced Metered Dosing Pump designed to automatically synchronize with your water flow rate. This ensures a consistent dilution ratio regardless of fluctuations, providing a level of accuracy that traditional setups simply can't match.
-
Superior Durability: Featuring full fluoro-elastomer construction, the MDP offers maximum chemical resistance. It significantly outlasts standard diaphragm pumps, drastically reducing maintenance and downtime.
-
Energy Efficient: Operates entirely without compressed air, lowering your facility's energy footprint and simplifying installation.
-
Reliable Under Low Pressure: Unlike venturi-based systems that fail when pressure drops, the MDP remains fully operational and accurate even with incoming water pressure as low as 30 psi.
-
Maintenance-Free Design: The "no-tank" configuration eliminates the need for frequent clean-outs and prevents the clogging issues common in reservoir-based systems.
-
Industrial-Grade Hardware: Built for longevity with stainless steel solenoid manifolds, featuring stainless plungers and valve stems for rugged, reliable operation.
-
Compact Footprint: The streamlined, space-saving design allows for easy integration into tight equipment rooms or existing production lines.

Smart Pressure Equipment
This high-performance system combines rugged hardware with intelligent automation to deliver precision cleaning in a compact footprint. By utilizing Variable Frequency Drive (VFD) technology and a single-line delivery architecture, it maximizes efficiency while eliminating the common failure points of traditional wash systems.
-
VFD Driven: Energy-saving Variable Frequency Drives allow the pump motors to ramp up or down based on demand, drastically reducing electrical overhead.
-
Triple Set Points: Easily toggle between High, Medium, and Low pressure settings to optimize chemical application for every stage of the wash.
-
Eliminate the "spaghetti" of poly-tubing. This system runs all low-pressure chemicals (including Tire Shine and Presoak) through the primary high-pressure line.
-
Auto-Purge Cycle: Chemicals are introduced at high pressure to quickly purge the line, then automatically reduced to your desired set point.
-
Burst Protection: By utilizing high-pressure plumbing for all applications, the risk of burst poly-tubes is completely eliminated.
-
MDP Integration: Every chemical application is powered by Metered Dosing Pumps, ensuring perfect dilution ratios regardless of water flow fluctuations.
-
Streamlined RO Feed: No need for a dedicated spot-free delivery pump; RO water is supplied directly to the inlet of the high-pressure pump for a seamless final rinse.
SPOT FREE
SYSTEM
Simple. Affordable. Reliable.
DDI’s Spot-Free Reverse Osmosis (RO) system is designed without the "frills" that drive up costs and lead to breakdowns. We’ve stripped away the unnecessary circuit boards and complex PLCs to focus on what matters: consistent, high-quality water production.
Key Innovations
-
Self-Cleaning Filtration: Our mixed-media pre-filtration removes chlorine and particles down to 5 microns. Equipped with an automatic backflush, it eliminates the hassle and expense of replacing disposable cartridges.
-
The "Never-Stop" Solution: Traditional systems use low-water sensors to shut your wash down when demand outpaces production. DDI does the opposite. When levels drop, our system automatically injects softened water into the holding tank. Your TDS might rise slightly, but your bays stay open and the line keeps moving.
-
Built to Last: We believe making spot-free water shouldn’t be over-engineered. By using standard, high-quality components instead of proprietary electronics, we ensure your system is easy to maintain and affordable to repair.
System Features
-
Plug & Play: Ready for immediate installation.
-
Heavy-Duty Frame: Anodized, extruded aluminum construction.
-
Precision Monitoring: In-line TDS meter and flow meters for product/reject water.
-
Ample Storage: Includes a 200-gallon storage tank with level control.
-
Auto-Maintenance: Chlorine and particulate removal with automatic backflush.
