Kaltra’s new one-piece manifold technology removes former limits of large microchannel water coils, enhancing reliability for data centers, AHUs, and free cooling systems.
ALTMUNSTER, Austria – With the commissioning of a fully automated tube-processing station capable of cutting and punching the complete range of manifold tubes up to 2400 mm in length, Kaltra can now supply microchannel coils equipped with solid, one-piece manifolds. This capability is particularly valuable for large microchannel water coils, where seamless manifolds significantly increase structural robustness, reduce assembly time, and lower overall production cost.
Beyond manufacturing efficiency, one-piece manifolds offer notable engineering advantages. By eliminating welded joints along the manifold length, the risk of leakage is reduced, pressure integrity is improved, and long-term reliability is enhanced.
The launch of the tube-processing station represents the final step in Kaltra’s transition to a fully integrated production line for large microchannel coils. Earlier, the company expanded its manufacturing capabilities by installing large-conveyor CAB furnaces, enabling reliable brazing of oversized heat exchangers and paving the way for large-MCHE production.
Historically, large-format microchannel water coils faced constraints in demanding environments—especially in data center applications, where they are used as AHU coils and free cooling coils, and where absolute reliability is essential. With the introduction of solid, one-piece manifolds and full-scale large-MCHE production technology, these limitations have now been fully removed.
As a result, Kaltra’s customers gain access to a new class of high-capacity, highly reliable microchannel fluid coils suitable for the most demanding and mission-critical cooling applications.
To date, Kaltra provides the widest nomenclature of tubes and components for microchannel water coils among all manufacturers. This allows the company to deliver tailored solutions that precisely match OEM requirements, ensuring optimal thermal performance, reliability, and integration across diverse applications.
