The Zhonghuan box furnace features low thermal conductivity due to the extensive use of TY ceramic fiber sheet throughout the insulating volume. This delivers fast heating and uniform cavity temperature. Under full power heating, the furnace can reach 1100 °C in less than 25 minutes. The heating element is made of 0Cr25Al5 iron chrome aluminum alloy wire.
These furnaces also feature micro-controller temperature control systems, automatic temperature measurement, display, control, and temperature maintenance.
The electrical control system uses a non-contact SCR module to improve the lifetime of the furnace.
The energy-saving box furnace includes air insulation technology that significantly reduces the surface temperature of the furnace shell. Over-temperature protection is employed to provide an extra layer of security.
