Custom Anodically Protected Strong Acid Heat Exchanger

Jiangsu Carpe Diem Ocean Equipment Co., Ltd. specializes in chemical processing equipment that withstands extreme temperatures. The Anode Protection Sulfuric Acid Cooler is their flagship product, engineered specifically for operations handling corrosive acids.

Advanced Corrosion Protection Technology

While appearing as a standard shell-and-tube heat exchanger, this equipment incorporates sophisticated anodic protection technology designed to handle 93% to 99% sulfuric acid at the drying and absorption stages of contact plants. Standard equipment fails rapidly under these conditions, but our anodic protection system ensures long-term durability.

Anodic Protection System Operation

The system maintains steel components in a controlled electrical state within the "passive zone" through three key mechanisms:

Protective Oxide Formation: Applied DC current creates an invisible oxide film over all acid-contacted surfaces, reducing corrosion rates by orders of magnitude
Continuous Monitoring: The system constantly monitors potential between steel and reference electrodes, with automatic controller adjustments to maintain optimal passive zone positioning
Robust Construction: Heavy-duty construction with rod baffles that simultaneously prevent tube vibration and enhance heat transfer efficiency

Key Performance Advantages

Superior Corrosion Resistance: Enables stainless steel to perform in environments where it would normally fail rapidly
Stable Protective Film: Maintains consistent protection across varying operating conditions, preventing gradual equipment degradation
Efficient Heat Transfer: Promotes turbulent flow and maximizes heat plate utilization for optimal thermal performance
Reliable Operation: Self-regulating system with remote monitoring capabilities minimizes unexpected shutdowns and leaks
High Temperature Capability: Safely operates at 160°C and higher, enabling effective waste heat recovery and energy efficiency

Engineering Excellence

Jiangsu Carpe Diem Ocean Equipment delivers coolers built for demanding acid plant applications. Our equipment combines robust construction with advanced protection systems, ensuring reliable performance in the most challenging chemical processing environments.
