1 Rack ovens Profitability and versatility for premium bakery outlets Found in the best bakeries of the world

2 Experience and innovation for outstanding bakers Sophisticated "Made in Germany" technology, high energy efficiency, better baking results and longer shelf lives WACHTEL ensures your long-term success! We have many decades of experience in the construction of baking ovens, we set ourselves firm quality standards and we are committed to meeting the changing needs of superior artisan bakers. We offer our customers highly efficient, top-quality rack ovens for long-term operation and outstanding baking results in locations where space is at a premium. Our philosophy for high-quality and efficient manufacturing of bakery products is uncompromising and runs through our entire wide range of rack ovens. The R-EVOLUTION flue gas circulator and electrically heated IMPACT ovens are among the most revolutionary developments on the market. The advantages of the traditional rack oven are combined with the strengths of the deck oven through the use of two heat transfer mechanisms, i.e. thermal convection and infra-red thermal radiation from the ceramic coating (ICT) that has been optimized in line with the requirements of bakery products. Benefit from this "bakery fusion system" and its outstanding synergy effects. With the combination of R-EVOLUTION and IMPACT it is possible to produce everything from small pastries through to large loaves at a high and reproducible quality while also saving on energy, materials and costs. 2

3 R-EVOLUTION the efficiency miracle with the heart of a stone oven The oil or gas-fired R-EVOLUTION rack oven combines traditional stone oven baking with all the advantages of modern rack oven technology. The R-EVOLUTION is the specialist system for artisan bakers with the highest quality standards. It enables the efficient production of a wide range of bakery products in high and reproducible quality together with energy savings of up to 30 %*. At the heart of this miracle of efficiency is the patented surface heat exchanger integrated in the baking chamber wall. This system not only provides additional thermal radiation to the bakery product but also gives a sensationally high efficiency level of over 90 %. Furthermore, the baking chamber inner walls have a special ceramic coating (ICT) that emits infra-red thermal radiation optimized for bakery products. The core of the dough is heated up more quickly which cuts down on baking losses and gives significant savings in terms of energy, materials and costs, as well as outstanding baking quality.

4 Compelling facts and figures for revolutionary rack oven technology Energy savings up to 30 %* Energy-efficient heat exchanger with a 13 m² heat exchange surface for a thermal efficiency of over 90 % and extremely low differences between flue gas and baking chamber temperatures (10 15 K). The equal of a deck oven Surface heat exchanger with internal ICT coating integrated in the baking chamber walls for a unique baking atmosphere thanks to the perfect combination of thermal convection and active infrared thermal radiation. Infra-red Ceramic Technology ICT Special ceramic coating for the intensification of infra-red thermal radiation specifically designed for bakeries; more rapid achievement of the dough core temperature for fresher bakery products, as well as savings in terms of time, materials and energy. High-efficiency radial fan Optimized airflow at low air speeds to eliminate the risk of goods drying out for an outstandingly even and reproducible baking quality. Energy-saving steam injector High-capacity steam injector warmed directly from the flue gas duct for rapid recovery times and generous steam injection batch after batch. High heat-storage baking oven mass Up to 400 kg* more thermal mass for baking at stable temperatures with low temperature losses after loading and unloading of just 5 15 K. Heating register for worry-free baking Robust heat exchanger made from highly heatresistant special stainless steel with 5-year warranty**. Increasing the quality of bakery products Up to 10 %* more baking volume; up to 30 %* less baking losses; increased moisture; longer freshness and lively golden crusts. *In comparison to traditional rack ovens ** Subject to specified annual servicing of the burner by an authorized engineer 4

6 Infrared Ceramic Technology (ICT) Special ceramic coating Intensive infra-red thermal radiation Accelerated heat transfer ICT-benefits: % energy savings* Approx. 6 % less flour use* Up to 10% more baking volume Up to 30 % reduction in baking looses* 100 % baking quality + Longer freshness + Increased moisture + Even pores + Vivid golden crusts IMPACT the fusion of two baking worlds for dramatic benefits With the electrically heated IMPACT rack oven, the baking chamber walls also act as oversized, powerful surface radiators. The insides of the baking chamber are provided with a special ceramic coating that emits infra-red thermal radiation perfect for bakery products. The advantages of the traditional rack oven are combined with the strengths of the deck oven thanks to the combination of two heat transfer mechanisms, i.e. thermal convection and infra-red thermal radiation from the ICT ceramic coating that is optimized for the requirements of bakery products. The advantages are clear a wide range of excellent quality bakery products. Efficient and resource-friendly production of premium pastries and large loaves, batch after batch: This is possible once you choose an IMPACT oven! * je nach Backofentyp, Backofenführung und Gebäck im Vergleich zum klassischen Backen 6

9 It's always about quality: Rotating turntable as standard High-quality alloy stainless steel Ball bearing protected from dirt and water Exact centering for rack carriage Stable anti-tilt turntable support Toothless gearing technology COMET the classic rack baking oven as an electrically heated, low-noise alternative Clean, quiet and emission-free COMET rack baking ovens are installed wherever the use of electricity makes economic sense. The COMET has no burner, flue gas circulation motors or flues that require servicing. There are therefore no costly, regular emissions inspections and the reduced noise level creates a pleasant environment for concentrated working. The powerful heating register has low power consumption levels. With our intelligent kw optimization software you can set the power consumption precisely and limit it to a maximum value with no compromise in terms of baking properties. High power peaks can therefore be avoided and basic loads can be set according to the most favorable tariff. This is of particular benefit where the required electricity supply is locally just barely adequate. 9

10 Specially developed, robust tube bundle heat exchanger High heat-resistant special stainless steel Large storage surface Counter-current principle Maximum efficiency COMPACT sophisticated technology is our pride COMPACT the classic rack bakery oven as a flue gas circulator COMPACT double rack oven maximized baking surface, reduced operating costs Our engineers are justifiably proud of the powerful and efficient crossflow blower. The generously dimensioned fan drum extends across the entire width of the rack carriage. It guarantees absolutely even air distribution and minimum air speeds with maximum energy utilization and uniquely low speeds (max. 1,420 rpm). This special development stands out from all other systems. The COMPACT 2.8 and COMPACT 2.10 double rack ovens are designed for two racks each with a maximum of 20 layers (84 mm clearance). Bakery products can be produced on a baking surface of up to 24 m² with an extremely small oven footprint. This gives benefits in terms of reduced energy and investment costs. 10
