HKFurnace has been designing, engineering, and manufacturing industrial furnaces and other heating equipment for 50 years.
Pit type Vacuum tempering furnace are commonly used for a tempering of heat treating applications including those requiring inert atmospheres, the tempering of austenitized and quench hardened steel.
Our industrial vacuum tempering furnace are provided for temperature ranges from 150ºC to 700ºC.
The pit vacuum furnace system offers a variety of temperature and vacuum controls,it to meet tempering, annealing a broad range or process requirements. And there are a mechanical blower pump systems and diffusion pump systems available.
Recirculating blower provides high velocity vertical down air flow for excellent heat transfer.Vertical down air flow specifically designed for tempering, uniform temperature distribution in furnace chamber.
