Five key benefits of electric heating in pit furnaces
Electric heating solutions offer considerable benefits to producers of steel and other high-strength metals. Here are five important reasons to switch from gas to electric in pit furnaces for ingot heating.
Minimal climate impact
Electric heating is the future-proof solution for companies seeking to minimize their climate impact. Kanthal’s electric resistance elements leave no carbon footprint, provided the electricity they use is generated from a clean, renewable source. Electric heating systems also consume considerably less power, contributing to better overall resource efficiency.
Optimal thermal efficiency
Whereas gas- or oil-fired furnaces release a significant amount of energy through the stack, an electrical solution means that most of the heat generated remains within the furnace. With thermal efficiency of more than 90 percent, businesses stand to save up to 70 percent on their energy bills when converting a pit furnace from gas to electric heating.
Safe working environment
Kanthal’s electric resistance elements contribute to a safer, cleaner working environment. Noisy, polluting and hot, gas burners can be risky to operators and are cumbersome to use, while Kanthal’s electric solutions are quiet, safe and clean. Furthermore, electric heaters produce no harmful nitrous oxide or poisonous carbon monoxide gas.
Gas burners produce local hot spots that may damage the material in the furnace due to overheating. On the other hand, electric heaters ensure temperature uniformity and even heat distribution throughout. The result is a reliable, repeatable heating process, regardless of the temperature requirement.
Accurate temperature control
While temperature control with a gas heater is largely guesswork, Kanthal’s systems are equipped with thermal controls, enabling you to get the temperature just right every time. This improves quality and saves time in the production process.
