Improvements in savings and ROI are not only results of low-consumption, but perhaps more important is the service life and maintenance time of the oven. For steam tube ovens specifically, the point of final failure is almost always the tubes. Over time, pressure and heat will deteriorate tubes that are manufactured with sub-par materials and/or manufacturing processes. For our ovens, Polin only uses the highest quality materials and optimizes the routes and bends of the tubes in order to achieve the minimum possible thermal stress. In addition, most manufacturers pressure test the tubes as a part of a sample size rather than every tube individually to save production costs. At Polin, we pressure test every tube at least five separate times to effectively eliminate the possibility of tube failure. The tubes are tested at pressures exceeding 10,300 psi when standard operating pressure is only around 1,250 psi. This is the only way to truly guarantee a service life that exceeds any of our competitors.
Through our innovative design and manufacturing process, we provide an oven that provides unparalleled levels of efficiency compared to other ovens. This efficiency is achieved through materials used for thermal insulation, low-emission glass, proprietary combustion chamber design, and motorized shutter on the chimney that better retains the heat, making better use of the fuel resources.
