Raise the drying chamber to 100–250°C with gold-plated medium-to-long-wave infrared lamps that direct thermal energy toward coated flat workpieces. Heat-resistant conveying components, insulated oven panels, controlled air circulation, and independent electrical control support continuous drying of coatings that require elevated process temperatures.
Application Materials:
Application Coatings:
The high temperature drying oven brings coated flat panels through a controlled 100–250°C thermal zone using gold-plated medium-to-long-wave infrared lamps. You can integrate the oven into a continuous coating line where the paint system requires elevated drying temperatures rather than UV curing or lower-temperature air drying. Standard working widths cover 580, 780, and 1280 mm, with different overall widths around the same 5000 mm oven length.
Your drying settings depend on the substrate, coating formulation, film condition, and required process time. Before defining the oven configuration, confirm:
The equipment supports coatings including PU, PE, NC, AC, water-based paint, fluorocarbon paint, and other compatible paint systems. Applicable substrates include fiber cement board, magnesium oxide board, calcium silicate board, glass, metal, and ceramics.
Gold-plated medium-to-long-wave infrared lamps provide the main heat source. Reflective lamp surfaces direct infrared energy toward the conveying area, while the enclosed oven structure retains heat around the workpiece path.
An 80 mm aluminum silicate insulation layer is installed around the sides and top of the oven. This separates the heated chamber from the outer structure and limits unnecessary thermal loss during continuous operation.
Inside the chamber, stainless steel conveyor rollers are wrapped with heat-resistant rope. The textured contact surface helps stabilize smooth workpieces such as glass while they travel through the heated section. Conveyor speed is adjustable through DELTA frequency control, allowing the residence time to follow the selected drying process.
You can place the oven after suitable coating equipment and before the next finishing or handling stage. For glass applications, it can form part of a glass spray painting line where coated panels require thermal drying. Other drying technologies are available within the paint drying oven range when your coating uses UV curing, infrared preheating, or hot-air drying instead.
Three standard versions use 60 kW full power, while custom oven dimensions can be configured around different workpieces and production layouts.
Custom high temperature drying ovens of different sizes are available for various products, and the parameters will vary accordingly. Please contact us.
The high-temperature drying oven utilizes gold-plated medium-to-long-wave infrared lamp tubes as its heat source. By leveraging the precise alignment between the emitted infrared wavelengths and the thermal absorption wavelengths, supplemented by the directional reflection provided by the gold plating, it is able to rapidly raise the internal temperature, achieving exceptionally high thermal efficiency and significantly shortening the paint drying cycle.
Our high-temperature drying oven was jointly developed with the Saint-Gobain Group and meets exceptionally high safety standards. The machine is equipped with explosion-proof motors with electromagnetic clutch, insulated heat-resistant bearings, and a standalone electrical cabinet featuring an industrial air-conditioning system. All wiring is concealed within insulated metal cable trays, comprehensively ensuring the equipment's safety and operational stability.
The high-temperature drying oven offers strong compatibility and can accommodate coatings with a wide variety of compositions. The length of the drying oven can be custom-designed or configured to suit specific coating characteristics and available space. In actual production, drying temperatures and times can be flexibly adjusted, and the unit can be seamlessly integrated with other equipment to facilitate highly efficient, automated production.
These IR lamps emit wavelengths that penetrate the coating surface, enabling rapid inside-out heating. Additionally, the gold plating’s high reflectivity and energy-concentrating properties ensure uniform infrared radiation coverage across all workpiece angles.
Both the sides and top of the oven are installed with comprehensive thermal insulation shields, internally filled with a dense 80mm high-performance aluminum silicate insulation layer, effectively minimizing heat loss and lowering heating energy consumption.
The stainless steel conveyor rollers are tightly wrapped with heat-resistant rope to prevent smooth workpieces, such as glass, from deviating or shifting in any direction. The conveying speed can be precisely adjusted by a Delta frequency inverter with vector output.
Equipped with high-quality, high-temperature-resistant bearings and a V-belt drive system, isolated from the high-temperature oven, this design outperforms traditional chain drives with lower conveying noise and safer, more stable long-term operation.
The standalone electrical cabinet with integrated HMI has an IP54 protection rating and is equipped with an industrial air conditioner, safety lock, internal lighting and external alarm light. Field wiring terminals feature digital labeling for easy maintenance.
Two intake fans are installed to supply fresh air and circulate it toward the VOCs exhaust port; this ensures more uniform temperature distribution within the oven while simultaneously expelling the solvents and harmful gases generated during the paint drying process.
The high-temperature drying oven’s safety guard is coated with heat-resistant paint and finished in a highly visible, aesthetic orange. Mounted away from heat sources, its outer surface stays below 50°C, with emergency stop devices installed at key positions.
In case of factory power failure, the electromagnetic clutch automatically disengages from the conveyor motor, turning the conveyor rollers into idlers. Workers can then manually remove workpieces from the oven with a handle to eliminate safety hazards.
