Yankee Hood System
High-velocity hot air hood for enhanced drying capacity and energy efficiency.
High-velocity hot air hood for enhanced drying capacity and energy efficiency.
The Yankee hood system complements cylinder drying with high-velocity hot air impingement, significantly increasing overall drying capacity and enabling the high production speeds that modern tissue operations demand. Parason's hood systems reflect our understanding that energy costs represent a dominant factor in tissue production economics.
Our hood designs are available in both natural gas-fired and steam-heated configurations, allowing selection based on local energy costs, emissions regulations, and site utility infrastructure. Gas-fired systems deliver higher air temperatures (400-530°C) for maximum drying intensity.
Central to every Parason hood system is the commitment to energy efficiency. Sophisticated heat recovery systems recapture thermal energy from exhaust air streams, reducing fuel or steam consumption significantly.
