No copper, no corrosion!
Why We Choose Cast Iron Over Copper
At Grid Industrial Heating, we prioritize durability and performance in every product we deliver. That’s why we use cast iron in our heating systems instead of copper. Why is this important? Because no copper means no corrosion—a key factor in ensuring your industrial heating system's longevity and reliability.
Understanding Corrosion and Copper's Vulnerability
Corrosion occurs when air, moisture, and chemicals like oxygen or sulfur react with metals. This can form a protective layer, like rust on steel, or speed up damage if the corrosion dissolves in water, with moisture acting as a conductor.
Copper tubing, especially in unit heaters, is particularly vulnerable to corrosion, especially when joined by soldering or brazing. When copper is connected to different metals, electro-chemical corrosion weakens the tubing, reducing its thickness and durability over time.
Why Cast Iron?
Unlike copper, cast iron is highly resistant to the wear and tear caused by corrosive environments. In industrial applications, heating elements are often exposed to extreme temperatures, chemicals, and moisture. Copper, while efficient at conducting heat, is prone to oxidation and corrosion over time, leading to system failures and costly replacements.
Advantages of Cast Iron:
Corrosion Resistance: Cast iron naturally withstands the effects of corrosion, making it ideal for harsh environments and extended operational life.
Durability: Built tough, cast iron components are designed to handle high-stress conditions without compromising performance.
Cost-Effectiveness: With fewer breakdowns and lower maintenance requirements, cast iron offers long-term savings compared to copper-based systems.
Thermal Stability: Cast iron maintains thermal integrity at high temperatures, ensuring consistent heat distribution and efficiency.
By choosing cast iron over copper, we help you avoid the pitfalls of corrosion, keeping your systems running smoothly and efficiently. Trust Grid Industrial Heating to deliver durable solutions for your toughest industrial needs.
