Designed to meet today’s environmental and sustainable development expectations, the Optima Evolution can be further enhanced with FRINGAND’s ECO-TEC technology. The results from this oven speak for themselves, offering greater economical and ecological benefits thanks to an integrated high-efficiency hearth, low-power burner, excellent rock wool insulation and very low chimney outlet temperatures. Description • Fully stainless steel front (hood, control panel, work surface). • Halogen lighting. • 20-mm refractory cement slabs. Advantages • Fast heat-up: 2 °C per minute. • High-performance steam generation. • Operates with very low “burner” power levels. The annular tubes ensure perfectly consistent heating, their radiance producing excellent baking quality. The OPTIMA’s all-metal design ensures working versatility and low energy use. The tubes used are TU37B steel, 21.6 mm in diameter and 3 mm thick. Each tube is formed, then drilled on a numerically-controlled drilling bench before being welded then tested at a pressure of 400 bar to guarantee proper sealing. (The operating pressure is around 140 bar). Heating system We use seamless cold-drawn individual tubes (1) in the OPTIMA oven’s heating compartment to give a large exchange area, positioned horizontally for the most effective exchange with the baking chamber. The transfer of energy between the hearth (2) and the baking chamber (3) is based on the phase change of the water and the natural circulation of the water/steam mixture in the tubes. Standard equipment • Type 304 austenitic stainless steel front hood and work surface. • Hood with in-built steam extractor.
