Pillar Induction, Brookfield, Wis., has commissioned a 75 kW medium-frequency induction melting installation at a precious-metal refiner in the Midwest. Pillar provided the complete system with water-cooled power leads, bus work and interconnection.
The new installation consists of one medium-frequency 150 lb steel-frame furnace with a hydraulic tilt system. A 75 kW, 3 kHz Pillar mK8 power supply powers the system.
A closed pressurized water-cooling system cools the power supply and three furnaces. The water-cooling system includes a single-pump pumping station.
