4. Frequently Asked Questions (FAQ)

Q1: What applications are best suited for this high-pressure wash tunnel?

A: It is ideal for commercial vehicle fleets (trucks, buses, construction machinery), rail equipment cleaning, and industrial pre-treatment processing (degreasing, phosphating, rinsing) prior to spray painting or coating.

Q2: How does the system handle water conservation and effluent management?

A: The system integrates multi-stage settling and filtration tanks with recirculating pumps, allowing wastewater to be filtered, treated, and reused for initial wash cycles to significantly reduce overall water consumption.

Q3: Can the tunnel dimensions and nozzled configurations be customized?

A: Yes. CoatTech designs custom tunnel lengths, heights, pressure parameters, and nozzled patterns based on the dimensions of the target vehicle/workpiece and specific throughput requirements.

Q4: How is oversized equipment shipped and assembled internationally?

A: Equipment is manufactured in modular structural units and shipped as disassembled components in ocean containers. Clear engineering blueprints and bolt-together connections enable fast, straightforward on-site installation.
