An Apples for Apples comparison of the data centre cooling landscape

1,449 views

Published on

This technical presentation provides an in-depth analysis of the multiple configurations of data centre cooling systems available.

Drawing on 40 years’ experience in the industry, Airedale International discusses the options available to achieve the optimum balance between energy efficiency, reliability and footprint, whilst reviewing capital and operational costs.

The presentation looks at the complete landscape from mechanical cooling through to full fresh air free cooling where PUEs of near 1.1 can be achieved, with and without adiabatic, and will take into account varied footprints.

Aimed at senior Technical and Financial decision-makers, the audience can expect a thorough analysis of current and future data centre cooling systems from the UK’s leading IT cooling solutions provider, as a basis for informed decision-making.
