Tired of frequent DX coil replacements due to corrosion in mixed fresh/saltwater environments? Our custom round aluminum alloy sacrificial anode is engineered to solve this pain point—extending your coil’s lifespan by 3-5 years, slashing maintenance costs, and ensuring stable operation of HVAC/refrigeration systems.
Why Choose Our Round Aluminum Sacrificial Anode?
1. Premium Al-Zn-In Alloy Material for Dual-Environment Adaptability
Unlike pure aluminum anodes that easily passivate (lose protection ability) in freshwater, our anode adopts high-purity Al-Zn-In alloy. The scientifically proportioned zinc and indium elements optimize electrochemical performance: it maintains stable sacrificial activity in both freshwater (low conductivity) and saltwater (high conductivity) media. It effectively forms a protective current to shield copper tubes, aluminum frames, and epoxy-coated aluminum fins (520 fins/m) from galvanic corrosion.
2. Fully Customizable Round Dimensions for Perfect Fit
Designed to be placed in the drain pan of DX coils, the round shape ensures stable placement and full contact with condensed water. We offer 100% custom dimensions (diameter + length) based on your drain pan size and protection needs—reference sample: φ200×35mm. Whether your DX coil is 2050mm×1200mm×100mm (as common in projects) or other specifications, we can tailor the anode to avoid space conflicts and maximize protection efficiency.
3. Flexible Configuration: Standalone Anode or Complete Kit
- Standalone Anode: High-purity Al-Zn-In round anode (ready for direct connection to coils)
- Complete Corrosion Protection Kit: Includes custom anode + insulated cables + mounting hardware (nuts, washers, clamps) + installation accessories—fully matching the functionality of Airefrig ACCP model, plug-and-play for easy installation.
4. Long-Lasting Protection & Cost Savings
With a protection lifespan of 3-5 years (depending on environment and size), our anode reduces the frequency of coil maintenance and replacement by 60%. It’s widely used in HVAC, heat pump, and refrigeration systems across Australia, New Zealand, and Southeast Asia—proven to lower total ownership costs for our clients.
