However, our equipments carry good protective function even without switch board prepared by the users. 3.One of the largest enterprises in the industry in Guangdong We are devoted to independent R&D as well as production. A rich variety of finished products and half-finished ...
Cooling water pressure 0.2-0.4MPa Furnace body weight 3t / set (without refractory lining) 2. Supply scope Furnace body 2 sets (includes: cover, frame, induction coil, yoke, tilting cylinder, water distributor, crucible, etc) Change furnace switch 1 set Bus bar from panel to furna...
In furnaces of this type, it is desirable also to provide a "holdfire" system to maintain the fire bed ready to supply heat upon demand, e.g., when the temperature in the comfort zone falls below the set point. The "holdfire" system should function only when necessary to avoid excessiv...
An electronic control (8) is shown adapted for use with gas furnaces which controls function and speed(s) of an induced draft motor (44), an igniter source
