Frequently Asked Questions

Q: How does the DY-QC-9 prevent scratches on the car paint?

The system uses new-generation soft foam cotton brushes and infrared automatic sensing to perfectly contour the vehicle's shape, ensuring thousands of soft bristles touch the surface without applying excessive pressure or trapping abrasive grit.

Q: What is the advantage of the double keel frame structure?

Unlike traditional single-frame designs, our double keel structure uses a two-layer skeleton of galvanized iron. This significantly increases the machine's stability, reduces vibration, and extends the overall service life of the equipment.

Q: Can the machine handle different types of household vehicles?

Yes, the DY-QC-9 is designed for various household cars with 7 seats or fewer. Its intelligent profiling system automatically detects the height, width, and length of each specific vehicle to ensure a complete clean.

Q: What safety features are included in the control system?

The system includes multiple safety layers: emergency stop functions, overcurrent/overvoltage protection for all motors, reliable grounding, and a self-diagnostic alarm system that shuts down the machine immediately upon detecting a fault.

Q: How efficient is the drying process?

The machine is equipped with four high-power 22KW fans that provide strong, fast-acting airflow to dry the vehicle surface quickly before it exits the tunnel, reducing the need for manual towel drying.

Q: Is wastewater recovery available for this model?

Yes, we offer an optional wastewater recovery system that can be integrated into the DY-QC-9 setup to help your business comply with environmental regulations and reduce water costs.
