Specification
Size
1,000 (w) × 800 (D) × 3,750 (H)
Power
220 V AC, 60 Hz, 10 A
Weight
150 kg
Utilities
Auto Moving System, Heat Flux meter, Water Cooling System
• Using the DAQ System, the MFC(Mass Flow Controller) & Inverter is controlled to match the air and gas supplied into the burner with the standard temperature curve.
• The burner’s On/Off and the open/close control is controllable at the Cover.
• Considered the safety and convenience of the user for the Auto Ignition system.
After the rise in temperature is complete, check the current of the wire and check whether there has been any melting of the cover causing short circuit
