Introduction to Corrosion-Resistant Microchannel Water Coils
Kaltra has expanded its microchannel water coil product line with a new generation of corrosion-resistant multiport tube technology. This technology is engineered for demanding applications, including HVAC, hydronic cooling, and industrial processes. The new microchannel water coils feature thicker-wall multiport tubes combined with a sacrificial zinc protective layer and advanced nano-scale coating applied to both internal and external tube surfaces.
Features and Benefits of the New Microchannel Water Coils
The upgraded design is intended to improve long-term corrosion resistance and operational reliability in aggressive environments. The key features of the new microchannel water coil platform include:
- Thicker-wall microchannel multiport tube construction
- Sacrificial zinc corrosion-protection layer
- Nano coating on both inner and outer tube surfaces
- Improved corrosion resistance and mechanical durability
- Optimized performance for hydronic and process cooling systems
- Extended operational life in demanding HVAC environments
Comparison of Microchannel Water Coil Technologies
| Feature | Traditional Microchannel Water Coils | Kaltra's New Microchannel Water Coils |
|---|---|---|
| Tube Construction | Thinner-wall multiport tubes | Thicker-wall multiport tubes |
| Corrosion Protection | Limited corrosion protection | Sacrificial zinc protective layer and nano-scale coating |
| Operational Life | Shorter operational life | Extended operational life |
| Performance | Lower performance in aggressive environments | Optimized performance in hydronic and process cooling systems |
Manufacturing Capabilities and Market Target
Kaltra has announced that recently installed automated tube-processing and manifold punching equipment now allows production of very long one-piece headers for large microchannel water coils. The new manufacturing capabilities help maintain low water-side pressure drop despite thicker tube walls. The first production series will primarily target the U.S. HVAC market, where demand for corrosion-resistant microchannel water coils and high-capacity hydronic cooling systems continues to grow.
Bottom Line
Kaltra's new corrosion-resistant microchannel water coils offer improved corrosion resistance, mechanical durability, and operational life in demanding HVAC environments. With its advanced nano-scale coating and thicker-wall multiport tube construction, the new design is well-suited for applications exposed to harsh operating conditions, including coastal installations, industrial atmospheres, glycol-based systems, and aggressive water chemistry. As the demand for high-capacity hydronic cooling systems continues to grow, Kaltra's new microchannel water coils are poised to meet the needs of the U.S. HVAC market and beyond.
