Rehm Thermal Systems RFS and RFS-D Fast Firing Systems offer a range of advanced process features and thermal control that enable PV manufacturers to move their processes to entirely new levels of efficiency and yield.
A holistic approach to energy efficiency has resulted in new benchmarks for reduced power consumption and ambient atmosphere influence. For example, Rehm’s RFS Fast Firing system measures in at a typical 17KWh, and the RDS Drying system a meager 7KWh. In addition, external cover temperatures are maintained at <35 degrees C .
Elegant design concepts applied to the construction and operation of the Fast Firing process chamber include a metal-free multi-layer construction of ceramic insulation, and an advanced air distribution system. This heat exchange concept heats ambient gas (clean dry air) up to process temperature while the chamber insulation is simultaneously cooled down by the gas flow.
Moving outward from the process chamber, the RFS employs three different layers of insulation, each with different key performance characteristics. The innermost layer is high temperature insulation most resistant to thermal shock and stress. An intermediate layer provides radiation reflection and the lowest thermal conductivity. The outermost layer is thermally efficient and designed to also provide superior mechanical strength. The results are measureable reductions in energy consumption as well as ambient room temperature impact, with the System efficiently managing 995 degree C internal temperatures while holding external cover temperature to <35 degrees.
