Yankee Hood

PERFORMANCE AND BENEFITS

Paper and Tissue production lines can benefit from our expertise in the engineering, design, development and manufacture of performant Yankee Hoods that can be classified in 2 families of products better known under the generic names of MG Hoods and Tissue Yankee Hoods. Here blow are some of the main features that demonstrate MDS’ strategy towards innovation and reliability.

HOOD DESIGN

• Hood-duty stable frame ensuring extended and stable performance and taking care of Yankee dryer surface
• Design distance 30mm from Yankee, the best efficiency vs. safety
• High-insulation and waterproof panels for extreme operating dew point and minimal energy consumption
• Fine and regular tuning of air flows spread in both CD and MD, including manually balanced air dampers and primary ducts (CD pitch ≤ 1000)
• Gentle exhaust reparation avoiding web sucking and take-off everywhere around the active area
• SMARTIARTM nozzles concepts (Air knives), the only one offering the highest drying rates compared to similar equipment available, and giving versatility to follow up machines evolution to meet markets demand.
• High efficiency fans driven by frequency variators fir minimal electricity consumption.
• Wide doors easily accessible from walkways for inspection, cleaning and eventual inside maintenance
• Perfect air balance whatever machine speed: no migration of air in bot MD&CD; no hot air loss at dry end, nor hazardous and penalizing fresh air introduction on both edges and wet-end side
• Fire detection and steam extinguishing system taking care of your machine

SPECIAL FEAUTURES

• Fine Automatic profiling System Controlled by customer QCS
• Moisture Control System controlling and adjusting exhaust flow (by oxygen rate measurement)
• Basic extended or full heat Recovery System providing up to 80% re-utilization of Hood Consumption
• HR Exchanger for make-up air warm up allowing the re-use of Yankee dryer condensates
• Special heating sources on request (electricity-thermal oil-fuels-gas turbine fumes)
• MG or Aircap hoods, naked or combined with a fabric wire
• Cascade Air System form medium or extreme capacity machines
• Single or Twin Direct Air System according to air flux requirements
• Wngineering for energy optimization
• Survey, assistance and revamping of existing installation
