Operating at medium voltages increases the efficiency of power distribution and consumption. A typical low voltage system will operate at about 96% efficiency.Losses result from heat generated by current transmission across wire, bussing, connections and instrumentation (known as I2R losses). A multi-megawatt process heating solution operating at 4160V and using the Chromalox SCR Power Control option maximizes efficiency to nearly 99%. That 3% improvement can translate into savings of thousands of dollars per year.
Unlike fossil-fuels heaters, the major parts of an electric process heater do not require regular maintenance and adjustments. But routine inspections of electrical connections help to ensure safety and maximize efficiency. The fact that medium voltage technology requires fewer wires and connections simplifies inspection time.
