Kaltra has announced the expansion of its microchannel water coil nomenclature with a new generation of multiport tube configurations engineered specifically for demanding hydronic and process cooling applications requiring superior corrosion resistance, long service life, and low fluid-side pressure drop.
The expanded product range introduces new microchannel multiport tubes with thicker wall construction combined with a sacrificial zinc protective layer and advanced nano-scale coating technology applied to both inner and outer tube surfaces. The new configurations are intended for application-specific water coils operating in aggressive environments, including industrial cooling systems, free-cooling applications, coastal installations, open-loop systems, and facilities using glycol or process fluids.
The first production series will primarily target the United States market, where demand for corrosion-resistant microchannel water coils and large-capacity hydronic cooling systems continues to grow rapidly across HVAC, data center, industrial, and free-cooling applications.
At the same time, recent investments in automated tube-processing and manifold punching equipment now allow Kaltra to manufacture significantly longer one-piece headers, enabling large microchannel water coils with optimized refrigerant and fluid distribution while maintaining exceptionally low pressure drop on the tube side.
The latest expansion of Kaltra’s microchannel water coil platform focuses on improving long-term durability under corrosive operating conditions while preserving the thermal and hydraulic advantages associated with microchannel heat exchanger technology.
