High Efficiency 1700 C Vacuum Atmosphere Furnace

SQFL-1700 vacuum atmosphere furnace is our new product through long research and improvement. Seven inches LCD touch screen, more easy to set the temperature program. It integrate the heating system, mixing gas system, vacuum system, circulating water cooling system, monitoring system. The machine with multi-functions can meet the most requirement of customers.

Main function and features:
1. SQFL - 1700 with double-shell structure and equipped with air cooling system, ensure the furnace surface have a low temperature, operation more safety.
2. Furnace chamber adopted imported alumina polycrystalline fibers material, with good insulation properties and more energy saving, Heating elements adopted Silicon molybdenum rod and depending on the working atmosphere plating different protective coating on the heating element, greatly improved the heating element servicing life.
3. The inner furnace chamber adopts high temperature resistant alloy materials, professional vacuum design, unique sealing technology, ensures no gas leak, vacuum degree more higher than our competitors’ similar products.
4. Reserved two gases inlet interface, can be individually control the gas flow; equipped with mixing gas device, can working with different protective gas, satisfy atmosphere experiment requirements;
5.This machine integrates the internal circulating water cooling system, to avoid the tedious work of external water connect, ensure the furnace surface have a low temperature.
6.Over-temperature alarm and power cut-off automatically, leakage protection, safe and reliable operation.
7.The experimental data can be stored and output; Reserved 485 convert interface, can be connected with PC through software. It can achieve remote control, real time tracking, history recorder, and output report function.

Main applications:
Widely used in universities, research institutions, industrial and mining enterprises to do high temperature sintering atmosphere, atmosphere restoring and vacuum annealing.

Our advantages:

1.Chamber adopts SUS304 stainless steel material, with unique water cooling design and seal technology, ensure good gas tightness of furnace chamber, vacuum degree more better than similar products which supplied by other suppliers.

2. Integrated water cooling system
The chiller was integrated in the furnace, ensure the cooling water working well, it cooling water seal technology make the furnace vacuum well.

3. Built in vacuum pump, max. Vacuum degree less 50Pa

4. Mixing gas system (standard configuration: two gas routes) 

5. Touch screen, operation more easy
