Medium Voltage (4 KV) Heater & Panel

Gaumer Process provides standard and custom engineered medium voltage (4KV) electric heaters and associated medium voltage control panels to meet high energy demand for various applications.

For generations, US manufacturing has been powered, quite literally, by fossil fuel. Natural gas, oil, and coal have historically run the workhorses of American industry – the heaters and boilers that process raw materials into usable products for a range of businesses, including oil and gas companies, chemical manufacturers, food processors, pulp and paper manufacturers, and petroleum refiners. Not surprisingly, these powerhouses have big appetites: 83 percent of all industrial boilers are fueled by natural gas and they eat up an astonishing amount of energy. As energy-intensive as gas-fired boilers are, they’re often equally emission-intensive. In particular, they produce carbon dioxide and nitrogen oxide, two pollutants that are coming under increasingly stringent regulation by the Environmental Protection Agency (EPA).

But now, with the successful introduction of the world’s first 4kV heater, industry has the power to change its energy source on demand. Like their natural gas counterparts, electric heaters are used for a variety of industrial and commercial processes, including producing hot water or steam and vaporizing liquid to gas. But that’s where many of the similarities end.

Electric heaters are emission-free at the point of use and boast nearly 100 percent thermal efficiency. They are more efficient in converting process fluid to vapor compared to conventional fossil fuel fired equipment, and there’s no stack loss – no wasted heat, unburned fuel, or excess air escaping up the flue stack.


Voltage - 4160 V

Large capacity and less infrastructure - A 1 MW 4kV heater has three wires, compared to dozens of wires and a transformer for a 600V electric heater. Reduced energy losses due to lower current flow are significant over the life cycle of the equipment.

Wattage available from 800 kW to multiple MW’s (20 MW +).

Easy installation - 90% less wiring and no step-down transformer

High efficiency - Efficiency of converting electricity to heat utilizing resistance heating approaches 100 percent.

Full thyristor controls - 1/3 the footprint of low voltage
