PERFORMANCE AND BENEFITS TECHNICAL SOLUTIONS<br />
<strong>Paper</strong> and tissue production lines can benefi t from MDS expertise in the engineering, design, development and manufacture<br />
of performant <strong>Yankee</strong> <strong>Hoods</strong> that can be classifi ed in 2 families of products better known under the generic names of MG<br />
<strong>Hoods</strong> and Tissue <strong>Yankee</strong> <strong>Hoods</strong>. Here below are some of the main features that demonstrate MDS’ strategy towards<br />
innovation and reliability.<br />
HOOD DESIGN<br />
• Heavy-duty stable frame ensuring extended and stable performance and taking care of <strong>Yankee</strong> dryer surface<br />
• Design distance 30 mm from <strong>Yankee</strong>, the best effi ciency vs. safety<br />
• High-insulation and waterproof panels for extreme operating dew point and minimal energy consumption<br />
• Fine and regular tuning of air fl ows spread in both CD and MD, including manually balanced air dampers and<br />
primary ducts (CD pitch ≤ 1000)<br />
• Gentle exhaust repartition avoiding web sucking and take-off everywhere around the active area<br />
• SMARTAIR nozzles concept (Air knives), the only one offering the highest drying rates compared to similar<br />
equipments available, and giving versatility to follow up machines' evolution to meet markets' demand<br />
• High effi ciency fans driven by frequency variators for minimal electricity consumption<br />
• Wide doors easily accessible from walkways for inspection, cleaning and eventual inside maintenance<br />
• Perfect air balance whatever machine speed; no migration of air in both MD & CD; no hot air loss at dry end, nor<br />
hazardous and penalizing fresh air introduction on both edges and wet-end side<br />
• Fire detection and steam extinguishing system taking care of your machine<br />

Capitalizing on more than 50 years of know-how and experience in hood technology, MDS is a full-scope supplier of<br />
reliable equipments dedicated to paper and tissue mills, and a well-known provider of state-of-the-art solutions.<br />
MDS <strong>Hoods</strong> are suitable for any production and machine speed; they offer better energy consumption rates than any<br />
other equipment available on the market.<br />
The design of SMARTAIR nozzles gives a higher heat transfer up to 20% compared to all other hoods, and allows<br />
to decrease the operating temperature by up to 50 to 80°C for the same production. As a result, heat consumption<br />
reduction can reach up to 6% of total heat demand (steam + gas) or up to 10% of gas consumption.<br />
The above fi gures are only some of the benefi ts that MDS can guarantee and which depend on each case study.<br />
Temperature levels drive the choice of the materials used in hood construction:<br />
• Aluminum nozzles for MG hoods up to 200°C (maximal permanent service temperature 300°C)<br />
• Stainless steel for class “B” and class “S” tissue hoods (up to 450°C)<br />
• Corten for class “H” extreme performance tissue hoods (up to 650°C)<br />
