YAMATO anaerobic high-temperature atmosphere furnace DNN430C/630C/460C/660C
An atmosphere furnace with an oxygen concentration of 20ppm and a maximum working temperature of 600 ℃, suitable for high-temperature heat treatment i
Product details
An atmosphere furnace with an oxygen concentration of 20ppm and a maximum working temperature of 600 ℃ is suitable for high-temperature heat treatment in anaerobic environments.
characteristic:
The maximum working temperature is 360 ℃ and 600 ℃, with an oxygen concentration below 20ppm. It is mainly used for annealing electronic components, LTCC removal, glass substrate annealing, ceramic degreasing, etc.
High airtightness pressure box structure, short time for oxygen concentration to reach, low N2 consumption.
High airtightness is maintained through magnetic sealing, and a water cooling mechanism is used to protect the sealing components from heat effects.
● It can achieve rapid heating and cooling, with adjustable heating and cooling rates.
The standard equipment is equipped with a waste liquid recovery device to cool and recover gases.
● LCD touch screen operation, with automatic/manual operation modes.
Security
● Equipped with door detection switch, temperature rise prevention device, oxygen concentration abnormality, nitrogen pressure detection, nitrogen flow detection, cooling water flow detection, water leakage sensor, overcurrent leakage protection switch and other installation devices.
