The chamber dryers of the KTR range can be used for complex drying processes and heat treatment of charges of normal weight and packing density to an application temperature of 260 °C. The high-performance air circulation enables optimum temperature uniformity throughout the usable space. A wide range of accessories allow the furnace to be modified to meet specific process requirements. The chamber dryers can also be used for production of laminated safety glass (LSG). During this process two panes are bonded using a laminating foil and entered into the oven inside a vacuum bag. From outside the furnace a vacuum is generated via hose connection in order to avoid air inclusions between the panes during the heat treatment.

• Tmax 260  °C
• Electrically heated (via a heating register with integrated chrome steel heating elements) or gas-fired (direct gas heating including injection of the hot air into the intake duct)
• Temperature uniformity up to ∆T 6 K according to DIN 17052-1 (for design wihout track cutouts)
• High-quality mineral wool insulation provides for outer temperatures of < 20  °C above room temperature
• High air exchange for fast drying processes
• Double-wing door for furnaces KTR 3100 and larger
• Over-temperature limiter with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the dryer and load
• Incl. floor insulation
