  • 1.Horizontal single chamber design and compact structure, furnace door opening mode can be designed according to user requirements;

    2.The cooling gas is ejected from the nozzle 360 ° around the heating chamber and evenly distributed on the rear wall of the heating chamber to realize the uniform cooling of the heat-treated products in the heating chamber;

    3.The heaters are arranged in circular sections, which can effectively improve the uniformity of furnace temperature;

    4.It can be rapidly cooled with a maximum pressure of 2.0 bars;

    5.he moving in-out motion of heat treatment products is automatic. From the initial of vacuum exhaust to the completion of heating and cooling, all motions are automatically controlled by PLC (applicable to large-scale products);
