MEGtec™ - Safe Furnace Cooling System

• MEGtec™ can replace water cooling on existing copper cooling elements, such as deep-cooled metal, matte and slag taphole blocks, and high-intensity sidewall coolers.
• Employs a mono-ethylene glycol (MEG)-based coolant mixture for enhanced safety and performance.
• Designed for high thermal efficiency to reduce taphole wear, stabilise furnace refractory linings, and maintain a competent slag freeze-lining.
• Operates safely under extreme furnace operating conditions.
• MEG-based coolant significantly reduces the explosion risk compared to traditional water cooling.
• Supports higher coolant flow rates for improved heat removal without compromising the existing piping system integrity.
• Incorporates an optimised and modular pumping and reticulation system design for easy conversion.
• Ideal for use in critical high-wear zones such as slag areas and taphole cooling blocks.
• Proven solution for increasing furnace operational intensity and campaign life while improving safety.
• Environmentally friendly coolant with low toxicity and corrosion inhibitors and biodegradable properties.

• Tenova Pyromets' MEGtec™ cooling system minimises the risk of explosions caused by water leaks, ensuring safer operation in high-temperature environments.
• It is ideally suited for applications where deep cooling is required such as metal, matte and slag taphole blocks, and high-intensity sidewall coolers in slag-matte tidal zones and adjacent to aggressive furnace slags.
• MEGtec™ delivers reliable thermal performance for freeze-lining formation and refractory stabilisation, supporting higher furnace productivity.
• Designed for seamless integration into both new and existing furnace cooling systems, minimising installation complexity and downtime.
• Tenova Pyromet customises every MEGtec™ cooling system to suit specific furnace process conditions, thermal loads, and operational targets across all furnace applications.
• Supports variable coolant velocities and high-temperature operation, with performance optimised for demanding smelting conditions.
• Uses a biodegradable, non-toxic MEG-based coolant, offering safety and sustainability without compromising performance.

• Backed by Tenova Pyromet’s full-service offering: from design and modelling to on-site support, commissioning, and ongoing performance monitoring.

Tenova Pyromet’s MEGtec™ system introduces a safer approach to furnace cooling by replacing traditional water with a mono-ethylene glycol (MEG)-based coolant. While water offers good thermal performance, it poses a serious explosion risk if leaks occur near molten metal or matte. MEGtec™ addresses this critical safety concern without compromising heat transfer capability.

The system combines Tenova’s precision-engineered copper cooling elements with MEG-based coolant to create a stable, high-performance solution for demanding furnace environments. It supports higher operating temperatures, protects refractory linings, and enables longer furnace campaigns.

What sets MEGtec™ apart is not just the coolant, it’s the complete engineered system. Tenova works closely with each customer to tailor the MEGtec™ system to their specific furnace design, critical cooled areas, and process conditions. This ensures effective cooling with a significantly lower risk profile. The MEGtec™ system comes in modules for easy installation and integration with existing cooling elements and systems.

MEGtec™ reflects Tenova’s commitment to practical innovation: safer, smarter, cost-effective, and ready for the increasing demands of modern smelters.
