The decorating lehrs have the same construction as the annealing lehrs:

Energy saving is the main factor in the whole concept of our lehrs. Extremely thick asbestos-free ceramic fiber between the inside tunnel and the outside case makes our lehr the best isolated lehr in the market.
Lehrs with a beltwidth of 1 to 5 m and variable length.

• The outside tunnel is a construction with heavy U profiles and sheet steel of 4 mm.
• The inside tunnel is a construction with heavy stainless steel U profiles and stainless sheet steel of 3 and 5 mm.
• The stainless steel fishbone belt support is made of 10 mm thick bars.
• The hot air circulation fans are in stainless steel and direct driven.
• The belt traction system is over dimensioned and allows a wide velocity range.
• The belt is driven over a large contact surface with a rubberized drive roller.
• The belt tracking system is easy to use and very effective.
• The plain entrance roller has a special design for cooling the ends and protecting the bearings.
• In the cooled sections the aspirated cold air is premixed with the hot air before entering in contact with the glass.
• The main electric panel can be equipped with temperature controllers or with a PLC.
• Temperatures can be controlled accurately at 1 C°.
• An electronic link to a plant supervising system is possible.
