Used GT SOLAR 513349 #9236055 for sale

GT SOLAR 513349 is a diffusion furnace and accessories that are designed to provide features for the production of high-quality and reliable crystalline silicon solar wafers. The product consists of an internal chamber and external chamber, with the external chamber consisting of an exhaust equipment, a low-pressure water manifold, and an adjustable relief valves. It also features two induction coils for the diffusion of phosphorous, boron, and other materials into the silicon substrate. The diffusion furnace uses an induction heating system combined with a sealed-chamber and water cooling unit, in order to provide precise temperature and atmospheric control. The induction heating machine is capable of providing a maximum temperature of 1670°C (3038°F) for silicon diffusion, and is controlled by a computer interfaced PLC/control unit, with a touch-screen display. The furnace operates at a vacuum of 10-2 mbar and features a gas mixture of nitrogen, argon, and oxygen with a DEOS tool. This prevents oxidation during diffusion. The furnace is equipped with a diaphragm pump to pump rare gases out of the chamber and maintain a low level of background oxygen. The silicon vapor pressure calculated from the thermodynamic models is used to accurately predict temperature during diffusion. The product also features a bushing-type gas feed asset, that injects boron, phosphorous, and other materials throughout the diffusion chamber. The material is metered using precision measurement systems. The product has a 180mm diameter lanthanum silicate boat, that is controlled by an electro-mechanical positioning model. For safety, the product also includes an emergency stop equipment and various safety valves and relief valves that prevent over-pressurization of the chamber. The exterior and interior chamber walls are made of high-grade 304 stainless steel, and the five-sided pyramidal top cover ensures adequate amounts of uniform heating and maximum efficiency. The product is an excellent choice for producing high-quality and reliable silicon solar wafers. The combination of precision and accuracy of the diffusion furnace combined with the bushing-type gas feed system results in precise control of the temperature and correct amount of material input for solar wafer production. The product meets safety regulations and is highly efficient, making it suitable for the production of a wide range of solar wafers.
