Frequently Asked Questions

Q: How does the DY-QC-9 ensure that it won't scratch the car paint?

The system uses a new generation of soft foam cotton brushes that are non-absorbent and 360° contouring. Combined with infrared profiling, the brushes maintain a safe distance from the body, ensuring a scratch-free experience.

Q: What is the "Double Keel Structure" and why is it important?

Unlike traditional single-keel frames, the double keel structure uses a two-layer galvanized skeleton. This significantly increases the machine's structural stability, reduces vibration, and extends the overall operational lifespan.

Q: Can this machine handle larger SUVs or only small cars?

The DY-QC-9 is designed for various household cars with 7 seats or less. Its intelligent sensing system automatically adjusts to the specific height and width of the vehicle within these parameters.

Q: What happens if there is a power surge or mechanical failure?

The machine is equipped with a comprehensive security system including overvoltage/undervoltage protection and an automatic fault detection alarm that shuts down the system immediately to prevent damage.

Q: Does the system include water recycling options?

Yes, an optional Wastewater Recovery System is available, allowing you to recycle water and reduce operational costs while meeting environmental regulations.

Q: How is the drying process managed in the tunnel?

The machine features four high-power 4kW fan drying motors that provide a strong, fast airflow to dry the vehicle surface quickly as it exits the tunnel.
