Thermal Air Purification for Metal Decorating Lines
HighEcon thermal air purification recirculates solvent combustion heat to the drying process, lowering external gas demand on metal decorating lines.
HighEcon
Thermal Air Purification for Metal Decorating Lines
- Integrated VOC air purification with direct thermal energy recovery
- Lower external gas demand compared to systems without heat recovery
- Primary heat exchanger engineered for thermal recovery efficiency
- Stepless exhaust volume control adapts automatically to production variations
- For new installations and retrofit for metal decorating lines without exhaust air purification
Thermal Exhaust Air Purification with Integrated Energy Recovery
HighEcon air purification
The HighEcon system provides thermal exhaust air purification on metal packaging coating lines. By recirculating process heat from solvent combustion directly into the drying chamber, the system lowers external natural gas consumption during continuous operation and job changeovers compared to dryer installations operating without exhaust heat recovery.
System architecture & engineering
The HighEcon system incorporates a fresh-air heat exchanger and a primary heat exchanger engineered for high thermal recovery performance. Variations in production conditions are automatically managed through stepless control of the exhaust air volume. The system is configured for new installations and demanding coating lines.
Core Technologies and Features:
- Integrated HighEcon Systems
Recirculates process heat directly into the drying chamber by utilizing solvent-laden exhaust air as a thermal energy source. Depending on the solvent concentration and operating conditions, external natural gas consumption is reduced by up to 70% under full-load operation compared to directly heated ovens without heat recovery. - Heat Recovery
Features primary and fresh-air heat exchangers designed for high thermal energy transfer. Automatic volume control balances variations in production conditions during continuous operation and job changeovers. - Support for VOC Compliance
Reduces volatile organic compound (VOC) emissions from the drying process, helping site operators comply with statutory industrial emission limits (such as EU Directive 2010/75/EU) under specified process parameters. - Application
Engineered specifically for metal sheet and drum coating lines processing solvent-based materials.
