Free cooling chiller

Free cooling chillers improve data center energy efficiency

/in


Over time, increasing power density and growing number of installed servers had increased the heat load on Telecity data center cooling system which operates on a 24/7 basis 365 days on the year. Existing fixed-speed chillers installed during the building’s construction could not meet the cooling demand and provide the necessary redundancy Telecity required. As a result, the cooling system needed to be upgraded to keep pace with the data center’s growth.

In-row cooling unit

Kaltra announces the second generation of in-row cooling units with a 50% capacity increase

/in ,


Among other innovations, Kaltra launches the second generation of its high-capacity in-row cooling solution designed for high power density data centers. With the cooling capacity of 141kW, Lambda In-Row is able to replace up to 4 typical in-row cooling units, saving expensive data center space for server racks.

Lambda In-Row has a new microchannel evaporator combined in V-form with a 41m² total heat transfer surface. With these evaporators, the cooling capacity of the new units increases from 90 kW to 141kW (for water temperatures of 15/21°C and inlet air temperature of 40°C).  A special type of manifolds for microchannel heat exchangers provide a uniform water distribution, and at the same time keeps low waterside pressure drop.
