 Pgl-1700c tubular vacuum furnace USES high-quality 1700 type silicon-molybdenum bar as heating element; Double shell structure, intelligent automatic temperature control system, SCR control, phase shift trigger. The chamber is made of polycrystalline alumina fiber, and a cooling system is arranged between the two shells, which can be quickly heated and cooled. It can flow into the protective gas or vacuum, vacuum pump can be optional according to customer requirements. Gas mixing system and high vacuum equipment are available.

Tubular vacuum atmosphere furnace main applications:
Used for high temperature atmosphere sintering, atmosphere recovery, CVD test, vacuum annealing test.
Tubular vacuum atmosphere furnace characteristics:
50 programmable digits
1. Equipped with KF flange with water cooling system to protect flange sealing. Easy to open and close, sampling is very fast and convenient.
2. The furnace cavity is made of high-quality polycrystalline alumina fiber with good insulation performance and durability; Better energy efficiency than any of its competitors; High quality MoSi2 bar is used for heating element, longer service life; The corundum tube of 99.99% has high density and is not easy to be broken.
3. Keep the vacuum and air port, which can be directly connected to our mixed gas system or vacuum system.
4. Reserve 485 conversion interface, which can be connected to PC through software. It has remote control, real-time tracking, history and output reporting functions. The paperless recorder can be installed for data storage and output (optional).
5. Built-in thermocouple to monitor the temperature of heating materials in real time (optional).
6. An observation window can be added on the flange to observe the status of sintered materials in real time (optional;
7. Over temperature will alarm and automatically cut off the power supply; And has leakage protection function, the operation is very safe.
