Container glass — Kanthal®

Kanthal’s electric heating systems, including the Globar® SiC portfolio, offer highly efficient and sustainable solutions for the container glass industry. Whether used in forehearth furnaces or annealing lehrs, our systems provide precise temperature control, significantly improving product quality while reducing energy consumption.

In forehearth furnaces, Globar® SiC elements ensure uniform heating and better control over glass temperature, minimizing defects and variations. As manufacturers return to electric heating for its higher efficiency and lower emissions, they benefit from customized solutions designed to optimize furnace performance and reduce maintenance costs.

In annealing lehrs for thinner container glass, Kanthal offers Fibrothal® heating modules with ROB meander elements for precise temperature control. For higher power and temperatures, Globar® SiC, Kanthal® Super MoSi2, and Superthal® modules provide reliable solutions. These electric heating systems ensure consistent heat, improving glass strength and durability while eliminating emissions.

With Kanthal, the container glass industry can meet the demand for efficient, clean, and reliable production.

Gas or electric: which is best for glass annealing lehrs?

Cost has traditionally been the deciding factor when glass manufacturers have had to choose between gas and electric heating in their annealing lehrs. But with increasing pressure to reduce CO2 emissions, there is a growing trend toward electric.

Why forehearth furnaces are returning to electric heating

As glass manufacturers shift back to electric heating for forehearth furnaces, the benefits of Globar® SiC elements become evident. Offering precise temperature control, improved efficiency, and zero emissions, Kanthal’s solutions ensure uniform heating, enhancing glass quality and minimizing defects. With decades of experience and tailored options, Kanthal helps manufacturers optimize energy use, reduce maintenance costs, and contribute to sustainable production.
