The Leisuwash DG (Dual-Gantry) model represents a bold engineering philosophy: two washing gantries working in tandem to deliver an express wash experience without sacrificing cleaning quality. This review provides an in-depth analysis of the DG’s design, performance, specifications, and ideal use cases to help you determine if it’s the right investment for your car wash business.
What Is the Leisuwash DG Model?
The DG is a dual-gantry touchless car wash system where two independent washing units operate on the same rail system. While Gantry A applies high-pressure rinse and detergent, Gantry B simultaneously applies wax and spot-free rinse on a different vehicle section. This parallel processing cuts wash time by approximately 40% compared to single-gantry systems.
Key innovation: The DG doesn’t just add a second arm — it uses intelligent path planning software that coordinates both gantries in real time to avoid collisions and optimize coverage.

Dual-Gantry Technology Explained
Synchronized Motion Control
Both gantries share a common rail but move independently. The control system uses:
Parallel Processing Workflow
“`
Time 0:00 → Gantry A: Front section (pre-rinse)
Gantry B: Rear section (pre-rinse)
Time 0:45 → Gantry A: Front section (detergent)
Gantry B: Rear section (detergent)
Time 1:30 → Gantry A: Moves to rear (high-pressure rinse)
Gantry B: Moves to front (high-pressure rinse)
Time 2:15 → Gantry A: Rear (wax application)
Gantry B: Front (wax application)
Time 3:00 → Both: Spot-free rinse & air dry → Complete

Key Advantages Over Single-Gantry Systems
Build Quality and Engineering
Frame and Structure
The DG uses a reinforced steel frame with hot-dip galvanized coating for corrosion resistance. All exposed fasteners are 304 stainless steel. The gantry rails are precision-ground to ±0.5mm tolerance for smooth, vibration-free movement.
Pump System
Two independent high-pressure pump systems (one per gantry), each rated at 60-80 bar. The triplex plunger pumps are rated for 10,000+ hours of continuous operation. Each pump has its own pressure regulator and bypass valve for safety.
Nozzle Technology
The DG features Leisuwash’s proprietary fan-jet nozzle array:
All nozzles are quick-disconnect for easy maintenance and replacement.
IoT and Smart Features
Leisuwash Cloud Platform
The DG integrates with Leisuwash’s IoT cloud platform for:
Remote Management
Operators can monitor and control the DG from any web browser or the Leisuwash mobile app. Key remote functions include:

Customer Testimonials
> “We replaced our old single-gantry system with the Leisuwash DG and our daily throughput jumped from 45 to 75 cars. The dual-gantry system really makes a difference during rush hours.” — Operations Manager, CarWash Express, Dubai
> “The IoT platform alone is worth the investment. We can see exactly how each machine is performing across our 8 locations, in real time.” — Owner, WashMaster Chain, Jakarta
Frequently Asked Questions
Q: Can the two gantries operate independently?
A: Yes. If one gantry requires maintenance, the other can operate in single-gantry mode at reduced throughput.
Q: What happens if both gantries try to reach the same position?
A: The collision avoidance system prevents this. The control algorithm assigns non-overlapping work zones to each gantry.
Q: How does the DG handle oversized vehicles?
A: The maximum vehicle dimensions are 5.8m L × 2.2m W × 2.05m H. Vehicles exceeding these limits cannot be washed.
Q: Is the DG available in cold-climate configurations?
A: Yes. An optional winterization package includes heated water lines, insulated bay panels, and anti-freeze recirculation.
Conclusion
The Leisuwash DG model delivers a compelling value proposition: dual-gantry speed without the premium price tag of European competitors. Its combination of fast throughput, low water consumption, integrated IoT, and competitive pricing makes it an excellent choice for high-traffic urban locations and growing car wash chains. If your business demands maximum revenue per hour and per square meter, the DG deserves serious consideration.
