CoatTech Delivers Cost-Effective Powder Coating Solution for AHU Water Tank Line

CoatTech Intelligent Equipment recently completed a customized technical proposal for a overseas AHU (Air Handling Unit) manufacturer, demonstrating how smart engineering can maximize ROI without over-engineering operational systems.

Matching Capacity with Lean Design

The client required a simple, reliable powder coating line to process heavy-duty AHU water tanks (up to3,800X 450X2,600mm and weighing up to300kg with a target daily output of approximate  200 pieces over a 12-hour shift. Rather than pushing expensive fully automated systems, CoatTech engineered an optimized semi-automated layout tailored precisely to the client’s production rhythm.

Key Technical Highlights:

1.4-Stage Pretreatment Layout: Compact setup covering Degreasing, Rinsing, Phosphating, and Final Rinsing to ensure optimal surface adhesion for large sheet metal components.

2.Energy-Efficient Drying & Curing: Dedicated dewatering oven post-washing, paired with a high-efficiency infrared curing oven designed for quick ramp-up temperatures and low energy consumption.

3.Flexible Workpiece Transfer: Integrated ground track trolley system allowings smoothy, manual/electric transport of heavy water tanks directly into the powder booth and batch ovens, reducing maintenance costs while maintaining high handling safety.

By aligning equipment capability directly with actual operational needs, CoatTech provided a lean, high-reliability solution that significantly reduces upfront capital expenditure and long-term utility costs.
