Water heater

for crystal growth furnace

Xi'an Refra Tungsten & Molybdenum Co.,Ltd is one of the best China heater manufacturers and suppliers, and as a professional company we have ou own productive heater factorywelcome to wholesale products from us. As heat source of sapphire crystal growth furnace, tungsten heater components have decisive function on temperature gradient of crystal growth, and the three district heating tungsten wire net heater has the characteristics of high temperature gradient adjustment ability, high efficiency and automation. Besides, tungsten itself has the advantages of high purity, high density, low vitalization in high temperature， sophisticated production, reasonable design of tungsten heater components take important role for Sapphire to control quality, save energy and service life. REFRA is specialized in producing thermal zone of high temperature furnace. The max temperature in furnace can reach to 2500℃. There are four structures: tungsten mesh、tungsten plate,tungsten strip and tungsten rod. The heat shield is processed with tungsten and molybdenum metal material. The temperature difference of uniform temperature zone is ±5°. This kind of furnace are widely used in sintering,annealing and brazing ceramic product industry.
