Vacuum heat treatment furnace capable of luminous treatment with N2 gas purge.
The NVPT series is a vacuum purge atmosphere tempering furnace that seals N2 gas under atmospheric pressure after vacuum purging, allowing for radiant treatment without the presence of oxygen or moisture through convection heating. This product is available in high vacuum specifications (equipped with an oil diffusion pump) and high-temperature specifications as options. 【Features】 - Excellent sealing bank structure, circumferential arrangement of heaters, and three-part control for improved temperature distribution performance. - Cylindrical heating chamber using ceramic fiber, convection heating/cooling fan, and heat exchanger arranged within the container. - In addition to convection heating, vacuum heating is also possible. *For more details, please download the PDF or feel free to contact us.
