Anodic Protection Acid Cooler 2nd Stage Shell and Tube Heat Exchanger 0.01 mm/yr Corrosion Rate

Chemical acid production frequently faces equipment degradation from high-temperature corrosive media, hindering continuous and efficient manufacturing. The anodic protection acid cooler is a specialized shell-and-tube thermal device engineered to address this industrial challenge.

The anti-corrosion advantage stems from precise anodic polarization control technology. The matching control system provides steady and precise bias voltage for the stainless steel surface in contact with acid, facilitating the generation of a compact, stable, and non-detachable passivation film.

• Creates a reliable barrier between metal materials and corrosive acid
• Limits annual corrosion rate within 0.01-0.03 mm
• Markedly better durability than conventional cooling equipment
• Circulating cooling water continuously removes heat from acid media
• Quickly adjusts acid temperature to meet industrial production standards

Designed with an integral fully welded structure, the acid cooler boasts a compact physique and flexible adaptability to various on-site installation conditions.

• Standard partitioned flow design: corrosive process acid flows through shell side, cooling water circulates inside tube bundles
• High-sensitivity detection and polarization control electrodes
• Intelligently adjusts operating parameters in response to real-time fluctuations
• Consistent anti-corrosion performance under variable working conditions
• Excellent heat exchange efficiency for long-term continuous operation

This professional cooling facility is widely used in core sulfuric acid production processes, covering material drying, tail gas absorption, and product purification.

• Overcomes weaknesses of traditional cast iron and ordinary stainless steel coolers
• Significantly prolongs equipment service cycles
• Reduces unplanned production halts and operational costs
• Enhances and stabilizes finished acid product purity
• Reliable anti-corrosion performance with energy-efficient heat exchange capacity

Featuring reliable performance and cost-effective operation, it has become a practical core device for modern acid chemical manufacturers.
