The supply includes:
– Set of electric fans for the waste gas draught, complete with:
- electric motors and driving belts
- base with shock absorbent support
- manually operated gate valves for bypass
– Motor control panel with variable frequency speed regulators (inverter), one per each motor. The variable frequency speed regulators will receive the 4รท20 mA signal from the furnace pressure controller.
The fans are manufactured in high temperature resistant steel, with clad and insulation, complete with doors for inspection and cleaning.
Main features:
- high pressure accuracy
- simple operation
- integration with any size of furnace
- easy maintenance
