KoldLok Raised Floor Grommets

Over the last few years the IT industry has seen a significant decrease in the use of floor space and a proportional increase in the use of IT infrastructure and its capacity. The energy consumed by hardware has also gradually risen per square meter. Data centre experts are thus confronted with more densely packed racks with higher and higher capacities which inevitably increases the ambient temperatures. This heat must be expelled by sufficiently large cooling and air-conditioning systems which in turn need a lot of electricity to generate the cooled air. The problem here is that a lot of the generated cool air (the US Uptime Institute estimates a loss of up to 63 per cent) escapes through unsealed cable openings in the raised floor before it even reaches the active hardware in the racks. This loss of cool air, known as bypass airflow, contributes to considerable energy inefficiency, helps hot spots form in the racks, pushes existing cooling systems to their limits very quickly and is generally a huge cost driver for air-conditioning in data centres.
