DRYING & CURING OVENS FOR PAINTING LINES
Energy Efficient Ovens for Modern Wet Paint and Powder Coating
Drying and curing ovens are essential at various stages of the painting process, ensuring that items are dried and coatings are cured effectively. Moldow combines advanced technology with effective insulation to deliver energy-efficient and cost-effective drying, hardening, and curing solutions tailored to your production needs.
Industrial manufacturers across Europe are under increasing pressure to reduce energy consumption while maintaining consistent coating quality.
The drying and curing processes, which require elevated temperatures, are particularly energy-demanding. As energy prices fluctuate and sustainability requirements grow, oven design and performance become crucial factors in overall line efficiency. At the same time, there is a growing expectation for reliable, consistent performance throughout the entire lifespan of the ovens. Moldow’s approach to designing and building ovens meets all of these demands.
Especially, three main factors influence the efficiency of a painting line oven: airflow, wall construction and heat regulation, which we elaborate on further down.
New Installations, Replacements, and Modernizations
Moldow supplies oven systems as part of complete painting lines and as upgrades for existing installations.
Whether supplying an oven as part of a modern painting line or replacing an older oven in long-running production line, the focus remains the same: increased efficiency, improved temperature control, and reduced operating costs.
In many cases, modernization or replacement of only the oven can deliver significant energy savings without requiring a full line rebuild.
Moldow offers a variety of ovens adaptable to different materials and production processes:
- Direct Fired, Gas Heated Convection Ovens: Efficient and flexible, suitable for high-temperature drying and curing.
- Electrically Heated Ovens: Energy-efficient solutions for those preferring electricity as a heat source.
- Hybrid Ovens: Highly flexible solution that enables switching between or combining energy types
- Infrared (IR) Ovens: Quick and effective heating, ideal for both surface and deep curing of various materials.
- UV Ovens: Utilizes ultraviolet light for rapid curing, perfect for coatings that require fast processing.
- Tunnel Ovens / Flatbed Ovens: Customizable tunnel ovens designed for high-volume production lines, providing efficient, consistent drying and curing.

HIGHLY EFFICIENT PROCESS
DUBALE CONSTRUCTION
FOR HIGH EFFICIENCY
The right oven designs ensures not only an efficient process and high-quality finish but also a long-lasting oven and thereby a solid investment.
Airflow: The Heart of Oven Performance
Generating the required airflow with fans that are custom-designed for the specific oven ensures the most efficient airflow, supporting fast and stable drying and curing for a wide variety of industrial products. If the fans are not designed to match the oven’s exact process parameters – such as temperature, pressure, product geometry, and required air flow – the result will be uneven heating, longer curing times, and, in the end, significantly higher energy consumption and lower curing quality.
In order to be able to achieve the above, all Moldow’s heating units have adjustable speed, controlled and adjusted by the overall control system.
Our ovens feature a specially designed air distribution ceiling that delivers vertical airflow for even and consistent ventilation throughout the drying or curing area. The heated air is recirculated within the oven, minimizing energy consumption while maintaining precise drying and curing conditions.
Construction: Built for Efficiency and Stability
Each Moldow oven is engineered to match the specific process, part size, and production requirements of the customer. Customized solutions are one of Moldow’s core strengths, ensuring that the entire oven construction is optimized for maximum efficiency and high-quality end result.
This includes:
- selecting insulation thickness according to operating temperature
- designing the wall construction to minimize thermal bridges
- adapting entrance and exit openings to the product dimensions
- configuring air curtains to match part geometry and heat-containment.
These design choices ensure consistent heating and minimal energy loss, regardless of line layout or product type.
Moldow’s ovens are designed with focus on fast and easy installation, without welding. In addition, the construction with a strong skeleton as the base and the high-quality insulated panels secure that heat expansion will never be a problem even after many years of use.

AVOIDING ENERGY LOSS
IS KEY TO SAVINGS
Energy loss is one of the silent cost drivers in many painting lines.
Every kWh escaping the oven is energy already paid for.
Preserving this heat is therefore directly reflected as money saved in daily operation.
Keeping Heat Where It Belongs
Moldow ovens are built with a self-supporting construction and high-quality insulated panels that minimize thermal bridges and reduce heat loss. This design achieves U-values down to 0.16 W/m²·K, ensuring that the energy used for heating remains inside the oven where it delivers value.
Key benefits include:
- Low temperature on exterior surfaces: less heating of the surrounding space and lower energy consumption
- Channel design and flow optimization: The process becomes very efficient and improve coating quality.
- Lower operating costs: Less heat loss, reducing total energy demand.
- Enhanced containment: Insulated ducts and high-efficiency air curtains keep heat inside the system, supporting long-term energy savings. In addition, this reduces heat emission into the production area and helps maintain a more comfortable working climate for operators – an increasingly important factor for staff well-being and employee retention today.
Tunnel Ovens and High Ovens
Moldow also specializes in tunnel ovens and larger oven plants, e.g. vertical ovens, tailored for specific applications beyond traditional painting and coating processes. Our oven tunnels are designed to handle high-capacity, continuous drying and curing, ensuring consistent results for various materials.
Typically, a very powerful airflow inside the oven, facilitated by our large, energy-efficient fans placed on top, ensure a very fast, efficient drying process.
We have successfully supplied these tunnel ovens for applications such as:
- Drying Insulation Plates: Providing efficient drying solutions tailored to insulation materials such as mineral wool.
- Drying Calcium Silicate Plates: Ensuring the precise drying conditions required for these specialized products.
Our customizable oven tunnels integrate seamlessly into your production line, maximizing efficiency and ensuring optimal performance for various industrial needs.
