Double doors Muffle furnace

This is a double door muffle furnace with sliding rails on each door, which makes load simple easy and cooling charmer fast to increase productivity. The furnace consists of high-quality alumina fiber brick and SiC heating elements with a chamber of 250x250x300mm and can be used up to 1400 C. It is designed for fuel cell module tests.

 

Features

 

Double door with sliding rails on each door, easy to load and unload from two ends.

4 different types:  1200℃ / 1400℃ / 1700℃ / 1800℃ Max.

Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.

Heavy-duty double-layer structure with cooling fan. Lower temperature in outside case.

PID automatic control via the current limiting phase angle fired the resistor, e.g. SCR (Silicon Controlled Rectifier).

Power control with 30 segments programmable.

Application Notes

 

1.The cooling rate of this Muffle Furnace shall also not exceed 10℃/min.

2.Toxic or explosive gases are not recommended for use with this furnace without necessary safety controls and supervision.

3.Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence and the cracks may be repaired with alumina coating.

4.A refractory door block must be inserted before closing door.
