CF-SL Firing Furnace With DriTech Dryer Specification Sheet

u CF-SL Firing Furnace with DriTechTM Dryer The world’s best selling firing furnaceFor highly efficient solar cells at the lowest possible cost, more solar manufacturers choose Despatch Firing Furnaces than any other brand.Combining the CF-SL with the revolutionary DriTechTM Dryer increases uptime and throughput and provides a lower cost of ownership. The CF-SL with DriTechTM delivers process repeatability and superior product quality.The furnace is now available with SolectFireTM Technology. This innovative technology provides greater thermal control and sets the stage for next generation pastes.The DriTechTM dryer is designed to decouple the VOC removal and binder burn-off for a more efficient drying process. A centrally located point-of-generation thermal oxidizer provides maintenance-free VOC abatement, ensuring that the chamber remains free of contaminates and that smoke and solvent don’t leave the ends of the dryer.The complete system offers 98% uptime, a smaller footprint and is easily integrated with every major metallization printer line. Maintenance is easy and quick with the patented push-button chamber design. Each tool is independently powered and controlled..
