10+ Years of Continuous Protection
CoilShield's cathodic protection systems provide long-lasting protection that extends coil life well beyond typical replacement cycles. The same technology protecting trillions of dollars of infrastructure worldwide.
How CoilShield Extends Equipment Life
By preventing all forms of corrosion—galvanic, formicary, acidic attack, and environmental stress—CoilShield ensures your evaporator coil maintains its structural integrity for years longer than unprotected systems.
Prevents Galvanic Corrosion
When copper and aluminum meet in the presence of moisture, an electrochemical reaction rapidly destroys the aluminum. CoilShield's cathodic protection reverses this process, making your coil the protected cathode instead of the sacrificial anode.
Prevents Formicary Corrosion
Organic acids from VOCs create branching tunnels inside copper tubes. CoilShield's continuous protection stops it from starting by maintaining the coil at a protected potential.
Prevents Acidic Attack
VOCs from cleaning products and building materials form acids that eat through metal surfaces. CoilShield neutralizes the corrosion potential before damage occurs.
Prevents Environmental Stress
Humidity, temperature cycles, and intermittent wet/dry conditions accelerate all corrosion processes. CoilShield provides constant protection regardless of operating conditions.
The Financial Benefits
Extending your coil's life by 10+ years means:
- Avoiding $850-$2,400 in out-of-pocket costs even with warranty coverage
- Avoiding 1-3 weeks without AC during the hottest part of the year
- Avoiding multiple replacements over your system's lifetime
- Maintaining comfort and productivity year after year
Proven Technology
CoilShield isn't a new invention. It's a new application of technology that has protected critical infrastructure for two centuries.
The global cathodic protection market exceeds $5 billion annually. Every new ship, every major pipeline, every underground tank uses the same electrochemical principles CoilShield uses.
Self-Regulating Protection
CoilShield's protection activates automatically when the coil is wet—which is exactly when corrosion occurs. The system is inherently self-regulating:
- Dry coil = no electrolyte = no corrosion = protection not needed
- Wet coil = electrolyte present = corrosion possible = protection active
Protection scales with need.
Universal Compatibility
Works with all coil types and HVAC systems from residential to commercial applications. Compatible with aluminum, copper, and mixed-metal coils. No system modifications required.
Prevention Beats Replacement
Don't wait for your coil to fail. Extend its life by 10+ years with CoilShield's proven cathodic protection technology.
