1200°C 3 Heating Zone Vertical Tubular Furnace with a maximum operating temperature of 1200°C.Mainly applied to the physical analysis of laboratory power materials,element determinationo,Can work under Vacuum,and can also work under a protetive atmosphere.In addition,there is an amazing function in this furnace namely in can be adjusted horizontal or vertical in different experimental using.


Furnace shell

  1. The shell is made of metal Q235 low-carbon steel, and the surface is electrostatically resistant and resistant to corrosion.
  2. The solid double-layer metal frame is combined with the heat-insulating fan structure, and the furnace surface temperature is low
  3. Vertical use mode, side open cover structure, easy to operate

Refractory material

Multi-layer insulation design, composed of lightweight alumina ceramic fiber and high-quality insulation board backing, does not contain asbestos components, low heat loss and low energy consumption

Heating system

  1. High-quality HRE spiral resistance wire heating element is safely and firmly embedded on the surface of the furnace, and is heated by free heat radiation in the furnace cavity, which is energy-saving and efficient, and has a long service life
  2. Ring heating by resistance wire to achieve good uniformity in the furnace
  3. Divided into three temperature zones, each temperature zone can be heated independently

Temperature Control Panel

  1. PID with SSR/SCR control mode, precise temperature control
  2. Internationally standardized N-type nickel-chromium-silicon thermocouple with a temperature measurement range of 0-1300°C and a long service life
  3. The furnace door is equipped with a door-opening power-off safety protection switch

Program Controller

  1. Advanced controllers that meet complex process requirements
  2. Simple and direct operation, flexible programming
  3. Programmable 30 program segments for a single curve
  4. Over temperature and fault alarm, automatic safety protection

Vacuum Atmosphere Function

  1. With 304 stainless steel sealing flange to obtain vacuum or atmosphere in the furnace tube
  2. High-quality alumina working tube, or metal or quartz glass working tube can be selected to adapt to different working conditions

Sealing Function

Both ends of the furnace tube are equipped with stainless steel metal flanges, matched with high-temperature PTFE gaskets, which can work under vacuum with a vacuum degree of ≤5pa (rotary vane vacuum pump)

Atmopshere Function

There are air inlets and outlets at both ends of the flange. The pressure gauge is installed on the metal flange. The precision needle valve can adjust the air intake and output, and can be fed with protective gases such as nitrogen, argon, and hydrogen.

Furnace Protection

Modular control, sound and light alarm signal will be sent out for over temperature and broken coupler in the working process, and the protection action will be completed automatically

Safety Protection

The equipment is equipped with a circuit breaker, which will automatically pop open in case of short circuit leakage, which can protect the safety of equipment and operators
