Kaltra to launch dual-circuit precision cooling units

Continuing to expand its solution portfolio for data center cooling, Kaltra releases dual-circuit precision air conditioners running on chilled water in pursuing optimum availability in mission-critical applications.

Dual-cooling circuit systems provide maximum reliability in thermal management, being connected to independent cooling sources, while in parallel enhancing system maintainability and flexibility.

New models with the dual fluid circuit will complement existing Lambda CW II-M models launched at the beginning of 2020. As with earlier models, dual-circuit air conditioners are equipped with large-surface evaporator coils and 2-way or 3-way flow regulation valves. These most modern air conditioners are supplied with EC-driven radial fans of the latest generation, onboarding with Modbus control.

Traditionally, Kaltra deployed microchannel type evaporators either for the new units to make them the most advanced and efficient solution available on the market.

Evolutionary control algorithms of Kaltra precision cooling units have proved to be an efficient approach and have been further developed in dual-circuit air conditioners of Lambda CW II-M series.

Lambda CW II-M is affordable while competitive solution for precision air conditioning, serving applications such as data centers, telecom and data rooms, and others.

The range of 40 new models – in addition to 40 models of single-circuit CRAH units – is scheduled to go on sale in Europe next month.

Headquartered in Germany and Austria, Kaltra designs, develops, and manufactures air conditioning and refrigeration equipment and systems. The company offers air-cooled, water-cooled, and free cooling chillersprecision air conditionersIT cooling systems, including room-, rack- and row-based solutions, and energy management solutions. It also designs and manufactures air-cooled condensersdry coolers, and cooling units for special applications. Additionally, Kaltra offers microchannel heat exchangers for condenser, evaporator, and water cooling and heating applications, as well as aluminium coils for small cooling applications. All Kaltra products are engineered with the clear objective of improving energy efficiency and reducing total cost of ownership.
