Lytron Acknowledged for Contributions to Datacom Liquid Cooling Guidelines

Liquid Cooling Guidelines for Datacom Equipment Centers

March 21, 2007, Woburn, MA: Lytron was acknowledged in Liquid Cooling Guidelines for Datacom Equipment Centers1 for its contributions to the book's development. The book was published in 2006 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and was recently made available for purchase. It provides guidelines to help engineers implement liquid cooling solutions for data center thermal management. Lytron, designer and manufacturer of liquid cooling systems, has been an active member of ASHRAE for over 10 years.

"ASHRAE TC 9.9 wishes to particularly thank the following people…Don Beaty of DLB Associates Consulting Engineers, Jeff Rutt of Department of Defense, and Kathryn Whitenack of Lytron for providing coordination and leadership on developing the individual chapters,"2 writes ASHRAE. According to the ASHRAE website, the TC 9.9, or Technical Committee 9.9, mission is to be recognized by all areas of the datacom industry as the unbiased engineering leader in HVAC and an effective provider of technical information.

Data center IT equipment today is predominantly air-cooled. However, with rack heat loads increasing, many data centers are finding air-cooling inadequate. This in turn has created the need to move towards liquid cooling. In the book, definitions for liquid and air-cooling as it applies to IT equipment are provided and the various liquid loops that can exist in a building that houses a data center are described. The book also provides an overview of datacom equipment cooling options, technical information on how to bridge the chilled water system with the technology cooling system, requirements of those liquid-cooled systems that attach to the datacom electronics rack, and more.

Kathryn Whitenack notes, "We're seeing more and more engineers turning to liquid cooling for a better thermal solution. Chapters 4-6 of the book provide an overview of liquid cooling configurations and requirements that will help engineers to effectively integrate liquid cooling into their datacom equipment centers. The book is particularly helpful for engineers with cabinet cooling applications and those new to liquid cooling. "

Liquid Cooling Guidelines for Datacom Equipment Centers can be purchased from ASHRAE for $50.00 by non-members and $40.00 by members by emailing or visiting the ASHRAE bookstore at
