Product Description

The equipment designed for pyrolysis, melting, analysis and production ceramics, metallurgy, electronics, machinery, chemical, glass, refractories, for develop new material ,special materials,construction materials,the equipment is suitable for institutions of higher learning and laboratory of scientific research institute and industrial and mining enterprises.

Characteristic:
1、Temperature accuracy：±1℃ ; Constant temperature：±1℃(Base on Heating zone size ) 。
2、Simplicity for operation ,programable,Using three micro computer control systerm, three different temperature zone can control temperature independently,three different temperature zone can be choose(low-middle-high or middle-low-high or high middle and low ) three temperature zone can controlled to obtain a longer temperature uniform zone.

PID autoinatic modify,autoinatic temperature rise, autoinatic temperature retaining , autoinatic cooling，unattended operation；Free software Provide to customer for uses compuer to doing operation the furnace. （start furnace、Stop furnace、Pause temperature rise、Setting temperature rise curve、temperature rise curve saving、 past records of temperature curve ）.
3、Furnace tube uses 99 alundum tubetube or quartz tube 。
4、Furnace surface temperature approach the indoor temperature.
5、double layer loop protection.
6、Importing refractory ，excellent temperature retaining effect，high temperature resistance.
7、Vacuum degree -0.1Mpa.
8、More gas options（Oxygen、Nitrogen、Argon、hydrogen and so on）

Gas control cabinet

Inlet gas type	2 options can be choose （1-10 type gas can be choose）
Mixture	adjusting the values of each Inlet flowmeter.
Valve	Imported stainless steel valve（ordinary valve, stainless steel valve, solenoid valve and so on can be choose）
Flowmeter	2 pieces 0-300 ml/Min（According to the quantity of air inlet，Mass flowmeter and Floating ball flowmeter and so on also can be selected）
Pressure test	Positive pressure、negative pressure double indictor pointer piezometer （digital display vacuum piezometer can be choose）
Vacuum pump	Double rotary vane vacuum pumps，Pumping speed 2L/min
Air pipeline	Special PV hose for gas (clean stainless steel tube can be used according to the demand of gas)
Pressure protection	The system is specially made to prevent the danger of closure of the exhaust port , the blockage of the exhaust port and the excessive pressure of the furnace tube. The signal is obtained by the electric contact pressure meter or pressure sensor then the drive control module will closes the electromagnetic inlet valve and starts the electromagnetic exhaust valve and the alarm. to ensure the furnace can be use properly and safely.
Gas leak alarm	Base on gas atmosphere, to prevent the gas leak；Gas leakage alarm detected (indoor) air toxic, dangerous and other gas content exceeds a certain value,then the drive control module will shut-down the furnace,closes the inlet valve and open the air exhaust,to get the better and safety working environment.
Can be customize for customer. Example: Pressure,Tube quality,Flux accuracy control, Remote control.
