Using DOWCAL™ 200 with Aluminum Heat Exchangers

Aluminum heat exchangers are widely used in HVAC, industrial, and process cooling systems due to their lightweight design and strong heat transfer efficiency. However, aluminum systems require careful fluid selection to prevent corrosion and maintain long-term performance.
DOWCAL™ 200 Heat Transfer Fluid is specifically formulated for use in systems with aluminum components, helping protect against corrosion while maintaining reliable thermal performance.
Why Aluminum Systems Require Specialized Fluids
Aluminum offers excellent heat transfer, but it is more sensitive to corrosion compared to other metals when exposed to the wrong fluid chemistry.
Using a standard glycol without proper inhibitors can lead to:
- Corrosion and pitting of aluminum surfaces
- Reduced heat transfer efficiency
- System contamination and buildup
- Increased maintenance and downtime
Selecting a fluid designed for aluminum systems helps avoid these issues and supports longer equipment life.
How DOWCAL™ 200 Protects Aluminum
DOWCAL™ 200 is engineered with an inhibitor package specifically designed to protect aluminum components.
Key benefits include:
- Corrosion protection tailored for aluminum systems
- Compatibility with aluminum heat exchangers and components
- Stable performance across a range of operating temperatures
- Reduced risk of system degradation over time
This formulation helps maintain system integrity while supporting consistent heat transfer performance.
When working with aluminum heat exchangers, fluid selection plays a critical role in system performance and longevity. DOWCAL™ 200 has improved corrosion protection to protect aluminum components, helping reduce corrosion risks while maintaining efficient heat transfer.
