Thermal Dryer (Coating)
for Metal Coating Lines
Modular thermal wicket ovens for coated metal sheets with integrated HighEcon air purification for external, internal, and protective coatings.

Thermal Dryer for Metal Coating Lines
- Integrated HighEcon air purification with thermal energy recovery
- AirFlow Pro baffles deliver uniform temperature across the sheet for sensitive coatings
- Cooling zone with temperature-controlled fan speed
- Real-time transparency of utility consumption data via touch panel
- Job data management with automated setting suggestions to assist quick setup times
Thermal Drying for Coated Metal Sheets
In the metal packaging industry, thermal drying is a proven all-round solution for the challenging demands of internal, external, and protective coatings. Continuous developments, such as the AirFlow Pro principle, promote uniform airflow in the heating zone, supporting the requirements of even sensitive BPA-NI coatings.
The heart of the system is the integrated air purification with the HighEcon system. It uses the solvent-laden exhaust air as a valuable energy source. As the solvent load increases, external gas consumption decreases accordingly, as thermal energy from solvent combustion is recirculated into the drying process.

Thermal Dryer Options

- H₂-ready burner systems: Flexible operation with natural gas, H₂ blends, or up to 100% hydrogen
- Variable fuel adjustment: Adjustable H₂ mixing ratios provide flexibility to adapt to fluctuating local fuel availability, pricing, and grid capacities

- Waste heat recovery: recovery and transfer of thermal exhaust energy from dryers into reusable process heat
- Versatile energy use: repurposing of energy for building heating, process water, or district heating networks

- Uniform Temperature Distribution in the Come-Up Zone
- Engineered for sensitive coatings requiring tight thermal tolerances
- Increased number of specialised baffle plates
- Prevention of localized overheating to eliminate hotspots
- Reduced turbulence and sheet movement for thin sheets
- Double-walled construction to minimize contamination risk inside the oven

- Tailored airflow for thin sheet processing
- Directed bottom airflow in addition to AirFlow Pro
- Reduced air turbulence helping to minimise sheet movement on the wickets
- Engineered to support process stability
