We are famous design manufacture company of vacuum equipment in China , and unique professional manufacturer which there are three kinds of technology such as vacuum , pressure, and cryogenic.
ZR-13 vacuum brazing furnaces for stainless steel
¡Â
Model ZR-13 high temperature vacuum furnace is mainly applied in vacuum brazing of vacuum vessels, oil-coolers, stainless steel plate-&-fin heat exchangers, and rocket nozzles, in vacuum bright annealing and heat treatment, and in high temperature degassing. ZR-13 high temperature vacuum furnaces feature as follows: 1300~1400 in temperature, 10-3~10-4Pa in vacuum degree, both forced cooling and natural cooling available, full metal horizontal/vertical structure, smart temperature control of single/multi-hot zones, both manual and automatic temperature control available, and curve setting and data saving.
