Pressure Relief Valve | Spring Loaded Type Pressure Relief Valve • Cracking pressure is manufacturer pre-set at 0.066Mpa (relative pressure value). • Valve close pressure: 0.03Mpa (relative pressure value). • Max. Temperature 200ºC. • 35mm O.D barb fitting for gas exhaust. |
||||
Gas Flow Control and Vacuum Valve |
• Two flow meters (#1: 0~8L/min; #2: 0~4L/min) are installed on the front panel of the furnace. • One heavy duty vacuum pump (CE certified) is built on the bottom of the furnace. |
||||
Water Cooling | • A 16L/min recirculating water chiller is installed in bottom of furnace for cooling furnace sealing flange. | ||||
Warranty | One year limited warranty with lifetime support. | ||||
Application Notes | • For preserving the longevity of the furnace components, we recommend the heating rate not to exceed 5 °C /min. • The cooling rate shall also not exceed 5 °C /min. • 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. • The refractory block must be inserted before closing door. |
