High-Airflow Heat Recovery Air Handling Unit (AHU) Series

High-Airflow Heat Recovery Air Handling Unit (AHU) Series

Engineered for Heavy Machinery, Aerospace, and High-Volume Continuous Coating Lines.

When operating large-scale spray booths for buses, heavy construction equipment, or aerospace components, the ventilation requirements are massive. Exhausting 30,000 to 60,000 m³/h of heated air during the curing and baking cycles represents a severe financial drain on your facility's operational budget.

Our High-Airflow Heat Recovery AHU is specifically engineered to handle these extreme volumes. By integrating an oversized cross-flow plate heat exchanger matrix into a robust, industrial-grade housing, this unit recaptures up to 68% of your exhausted thermal energy. It is the definitive solution for large-scale manufacturers looking to achieve carbon compliance and drastically lower their heating costs without slowing down production.

Core Engineering Advantages

1.Massive Volume Processing: Specifically designed modular cabinets accommodate high-velocity airflow from 30,000 m³/h up to 60,000 m³/h, ensuring stable pressure within large spray environments.

2.Zero Air Mixing (0% Cross-Contamination): In aviation and automotive finishing, dust and VOC contamination mean costly rework. The physical plate separation guarantees that dirty exhaust air never touches the fresh supply air.

3.Heavy-Duty Cabinet Construction: Housed in double-skin galvanized steel panels with high-density rockwool insulation (50mm/75mm) to prevent thermal bridging, minimize condensation, and reduce noise transmission on the factory floor.

4.Automated Bypass Integration: Can be equipped with motorized bypass dampers. During the summer months or non-heating phases, the air automatically bypasses the heat exchanger core to reduce static pressure and save fan motor energy.

Technical Specifications: High-Airflow AHU

Frequently Asked Questions (FAQ)

Q1: What are the primary advantages of combining a downdraft system with infrared curing lamps?
A: This combination offers the ultimate environment for a flawless finish. The full downdraft airflow continuously pulls airborne dust and overspray straight down into the floor filters, away from your paint job. Meanwhile, the shortwave infrared lamps cure the paint from the inner layers outward. This prevents "skinning" (where the surface dries first, trapping solvents underneath), minimizes the risk of pop-boiling, and cuts your overall baking time in half compared to traditional hot-air convection booths.

Q2: Can the wall-mounted infrared heating zones be controlled independently?
A: Yes. The integrated infrared heating system is segmented into multiple independent zones controllable via the main panel. For smaller panels, spot repairs, or bumper touch-ups, operators can activate only the specific heating zones required. This targeted curing significantly reduces power consumption and lowers operating costs.

Q3: Is this spray booth fully compatible with waterborne paint systems?
A: Absolutely. Waterborne paints require precise, uniform airflow and controlled thermal energy to break the water barrier efficiently. The combination of clean, high-velocity laminar downdraft air and direct, shortwave infrared radiant heat ensures exceptionally rapid water evaporation and cross-linking, making it highly effective for both solvent-based and waterborne paint lines.

Q4: What is the recommended maintenance schedule for the filter elements?

A: To maintain optimal cabin pressure and a pristine, dust-free environment, we recommend the following replacement intervals under normal operating conditions:

1.Pre-Filters (Intake Air): Every 100 working hours.

2.Ceiling Fine Filters: Every 400 to 500 working hours.

3.Floor Paint-Stop Filters (Glass Fiber): Every 80 to 100 working hours, or when visible overspray accumulation slows down the exhaust airflow.
