The system is in very good and well-maintained condition and is suitable for the professional processing of both conventional and water-based paints. It can be used flexibly in spray and drying operations and features a powerful supply and exhaust air system, natural gas heating, heat recovery, and a modern PLC and frequency inverter control system. Technical highlights and features: • Manufacturer: DURST Lackier- und Trocknungsanlagen GmbH • Type: D-LTA 30/30-ü-natural gas • Year of manufacture: 2022 • Design: combined painting and drying booth • Booth internal dimensions: approx. 10,000 × 5,000 × 3,000 mm • Booth external dimensions: approx. 10,800 × 5,160 × 3,080–3,780 mm • Air flow rate: approx. 27,000 m³/h for both supply and exhaust air • Motor power of ventilation: 2 × 11 kW • Total electrical connection: approx. 25 kW • Heating power: up to approx. 250 kW • Heating: direct gas surface burner, natural gas Lrodpfszubtlsx Aa Rjr • Drying temperature: up to approx. 70 °C • Air changes: approx. 180 times • Air velocity: approx. 0.50 m/s • Heat recovery via cross-flow heat exchanger • Manufacturer's specification for heat recovery: approx. 47 % efficiency on average per year, up to approx. 80 % recovery factor under optimal conditions • DURST EcoTronic system with frequency-controlled fan control • Operating modes including spray operation, partial load operation, stand-by operation, and hall heating operation • HPS heating program control for efficient drying, especially for water-based paints • PLC control with frequency inverters and monitoring devices • Remote maintenance module • LED ceiling lighting, Ex-Zone 2 • Illumination level approx. 1,090 Lux • Rear extraction wall with paint mist separator • Pre- and post-filtration of the supply and exhaust air • Partial filter ceiling with fine dust filtration • Sectional door and two partially glazed emergency exit doors • Insulated, double-walled booth housing with 80 mm mineral wool panels In spray operation, the system operates in fresh air/exhaust air mode. The drawn-in fresh air is filtered and heated via the gas surface burner. The exhaust air is passed through the paint mist separator and post-filtration. In drying operation, the system operates primarily in recirculation mode with a fresh air proportion of approx. 10 %. The integrated HPS control system enables energy-efficient and uniform drying and is particularly interesting for processing modern water-based paints. Another significant advantage is the integrated heat recovery system, which allows a considerable amount of the heat contained in the exhaust air to be fed back into the process. The system dates from 2022 and is in very good condition. Due to the generous booth dimensions, the high air flow rate and the extensive control and energy technology, it is ideally suited for industrial and commercial painting applications. Further technical documents and documentation for the system are available and can be provided upon request.
