Our Proven Track Record Speaks for Itself
Altek has nearly 15 years of experience designing, manufacturing and installing furnace circulation systems on various furnace types. Our extensive knowledge of the best operating practices helps us stand apart from the rest. By providing market-leading, high-performance equipment, we ensure our customers optimize operations to maximize profitability.
Electromagnetic Stirrer (EMS)
Over 100 successful reference installations worldwide have increased furnace performance. The Altek inductor is 100% air-cooled and does not require a complicated, expensive and potentially unsafe water-cooling system close to the furnace.
Permanent Magnet Stirrer (ViPER™)
Commercialized in 2022, this technology has been trialed, tested and the first system has been successfully installed into the UK. The ViPER is a compact (small) system with very low energy OPEX, has excellent operation at low metal depths, is 100% air cooled and is operator friendly.
ALTEK Air cooled EMS, removes the requirement for water near your furnace, making the casthouse a safer environment.
Reduce Energy Consumption
By up to 25% with ALTEK EMS by preventing super heating of melt surface and sub-surface circulation of the melt.
Reduce Melt Loss
By up to 25% with our EMS by preventing super heating of melt surface and sub-surface circulation of the melt.
Improved Operator Safety
Improve safety and efficiency through automated furnace stirring whilst also limiting damage to refractory lining.
The most versatile and cost-effective electromagnetic furnace stirring system in the industry. Based on the principal of a linear induction motor, a low-frequency air-cooled inductor is placed on the bottom or side of a furnace to increase productivity and reduce energy consumption.
Patented controls and design system
Easy to retrofit to existing furnaces
Side or bottom mounted applications
Based on the versatile EMS Range, the curved EMS is designed for applications where the furnace shell is curved or rounded, specifically dome furnaces.
Patented controls and design
An industry first, taking the benefits of circulation to round furnaces
Increase productivity and reduce gas consumption
