DUAL AIR BLOWERS
Two are Better Than One.
Using double air blowers gives us more flexibility and precision in the amount of air available for the melting and holding chambers at any given time. When balanced correctly they increase the efficiency of the furnace and reduce running costs.
VFD DRIVE BLOWER MOTORS
Better Efficiency and Lower Operating Cost.
Lots of air without control wastes a significant amount of energy. We use VFD Drives combined with Premium Inverter Duty Motors to give you greater RPM only when it is needed. All this translates into greater efficiency, lower operating costs, quieter operation, soft start and longer motor life. The advantage is clear. This is just one of the many ways we use to increase furnace efficiency, and reduce long term operating costs.
