Adopting the worldwide most advanced type non-aluminum sticking furnace materials, and with the advantages of whole body casting process, infiltration free, no leakage, good heat preservation and longer life span. 
Holding furnace capacity: 200-1300kg; maximal furnace cavity working pressure: 1.5bar. 
Top heating mode and bottom immersing heating mode optional. 
Single-chamber and dual-chamber holding furnace optional.
Two-chamber holding furnace has the advantages of more cleaner, uninterrupted production and little oxidation; it can save above 40% electricity consumption combining with the bottom heating technology. 
Detecting the al-liquid temperature directly.
SIC ceramic riser tube. 
Adopting the imported self-tuning PID temperature controller and the al-liquid temperature can be controlled within ±2 degrees. 
Having the function of over-temperature protection to avoid the furnace temperature out of control. 
Power control units made up with high reliable intelligent power adjuster to prolong the carbon rod life span. 
Single rotating shaft feeder door can be opened and closed horizontally (can rotate to 180 degree)
Holding furnace equipped with 2bar safety valve to present furnace over pressure.
