Furnace Power Supplies

Closer to the Heat Source to Optimize Furnace Systems

Our water-cooled power supplies are smaller and lighter, so they can be positioned closer to the heat source. This helps reduce electrical losses in the power delivery system.

Increased Efficiency and Reduced Costs

Close-coupling improves efficiency, while substantially reducing energy, installation, operation, maintenance and capex costs. Our systems are designed for your application to electro-mechanically integrate with your power. They are available in various voltages and frequencies.

Stack-Up Saves Space

The size of our power supplies allows them to be stacked-up next to the heat source, reducing the need for costly transformer cabinets.
