Wherever a solid, straightforward, yet exceptionally well-equipped machine is needed, the DuoFlex Spray surface spray machine comes into play. Spraying doesn’t have to be complicated – not when you have a robust, long-lasting machine (made in Denmark, electronics from Germany – Beckhoff and others) that puts the operator at the center of it all. Everything is intuitive and easy to use, yet you get features you’ll struggle to find elsewhere – or only in significantly more expensive machines. Here are some hard facts about the DuoFlex Spray: 1. Color changes in just 3–5 minutes 2. System volume only 2.5–3L of paint/lacquer 3. Suitable for both solvent-based and water-based coatings 4. Two fully separated circuits – ideal for solvent/water or clear/topcoat separation 5. Maximum reproducibility – thanks to smart programming that stores all key parameters automatically 6. Quick to learn – after just 4–6 hours of training, even a baker can spray better than a manual sprayer with 10 years’ experience 7. Modular expandability – drying systems, sanding units, preheating, robotic integration – all from a single source 8. Service that speaks your language – our owner spent nearly 10 years as a coatings manager and brings hands-on expertise to your shop. The machines are extremely durable, and if anything should go wrong, we maintain well-stocked spare parts warehouses in both Germany and Denmark Processing dimensions for the DuoFlex Spray: 1. Standard: 1,300 mm width × 200 mm height 2. Larger: 1,800 mm width × 200 mm height 3. Up to: 3,200 mm width × 330 mm height Length: from 250 mm up to virtually unlimited. If you want to coat CLT ceiling panels 16, 18, or 20 meters long, we’ll simply build the right handling system for you. Sound interesting? Would you like to try the machine in our technical center? Do you have specific requirements and wonder if we can deliver? Then I’ll be happy to help you personally.
