Press Release Summary:
Designed to optimize climate conditions, Cocooning Chimney comes in passive and active variants suited for use as part of free air cooling system that uses ambient air to remove heat from data center. Cocooning via vertical chimney ensures hot exhaust air from one rack, row of racks, or complete aisle is ducted to ceiling hot air return plenum without affecting aisle temperatures. These solutions are designed to be used alongside airside economizers.

Cannon T4 Inc's Cocooning Chimney Takes the Heat Out of the Situation
Cannon T4 Inc, the international leader in innovative containment systems, has announced the introduction of its latest product designed to optimise data center climate conditions – the Cocooning Chimney. Available in passive and active variants, Cocooning Chimneys are perfect as part of a free air cooling system, which uses ambient air to remove the heat from a data center.
Free air cooling delivers energy efficient and cost effective data centers, however, one of the key challenges is providing the correct balance between cold aisle temperature, IT equipment fan speed and hot air return temperature. Cocooning via a vertical chimney ensures hot exhaust air from one rack, a row of racks or a complete aisle, is ducted to the ceiling hot air return plenum without affecting aisle temperatures.
Cannon T4 Inc’s managing director, Matthew Goulding, explains, ‘A passive system uses the server / IT and air handler fans to provide air movement through the Cocooning Chimney. This creates a sealed environment for the air to travel through, ensuring that cool air does not mix with heated exhaust air. Alternatively, an active system involves the use of fan trays to provide forced airflow up through the chimney. Cannon T4’s automatic, variable speed temperature controlled fan trays boast an adjustable telescopic design for indeterminate installation heights or single piece construction.’
Cannon T4 has used its vast experience in chimney design and configuration within the Cocooning Chimneys, and to eliminate the common problems associated with free cooling – polluted air, pollen, insects and humidity – it has designed them to be used alongside airside economizers. Perfect for retrofitting, they bring ambient air in, filter it and then mix it with exhaust air to raise the temperature if required. The air is then passed either through an air-to-air heat exchanger, or direct and through a back-up water or DX air coil, in order to get the right temperature for the room.
To assess their effectiveness, Intel looked at the impact of airside economizers where the outside air temperature was 90°F (32°C). It estimated that a 10MW facility would save almost $3m per year and that the risk of increased equipment failure was so low as to be insignificant.
As well as offering brush sealed cable containment solutions that pass through the Cocooning Chimneys and out to cable raceways and basket, Cannon T4 can also provide aisle roof designs and custom chimneys to suit various ductwork requirements. This is backed up with a service that includes site surveys, bespoke system design, heat extraction calculation, fast and efficient manufacture, installation and testing.
‘The popularity of free air cooling is not surprising given that it can help deliver a power usage effectiveness (PUE) rating as low as 1.05, against an industry average of 2.0,’ concluded Matthew Goulding. ‘Our pioneering new Cocooning Chimneys can play a vital role in reducing the cost of cooling, making data centers more energy efficient and getting the most out of ambient temperatures.’
