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.
For decades, data centers have used raised floor systems to deliver cooled air to the server racks. Cooled air discharged by a computer room air conditioner (CRAC – a split air conditioning system or system with fluid coolers) or air handler (CRAH – a chilled water cooling system connected to air-cooled or water-cooled chillers) creates high pressure in the underfloor space.

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.
Kaltra Innovativtechnik, a Germany-based provider of innovative thermal management technologies and advanced cooling equipment, today released the Lambda DX/DXU family of feature-rich, high-end direct expansion (DX) precision air conditioners with innovative microchannel evaporators and dual refrigerant circuit amongst many of its features.
Kaltra Innovativtechnik, a Germany-based cooling specialist, has launched its chilled water rack-based cooling solution intended for use in high-density data center applications. The development of the In-Rack solution is in response to growing demand for high-density cooling solutions from the data center sector for energy savings and reduction in carbon emissions.
