ECHO High Efficiency IT Cooling System The high efficiency ECHO IT Cooling System is the perfect, future-proof solution to meet the cooling parameters of latest IT hardware, not only in terms of temperature but also airflow and pressure. This ensures the right air temperature, in the correct quantity and at the correct pressure is presented to the server inlet, enabling it to breathe efficiently. By varying the air volume, the ECHO system operates not only with air volumes 50% less than traditional cooling systems but much more efficiently and with elevated water temperatures that allow up to 95%* free-cooling (London, UK). Complete, flexible, free-cooling solution At the hub of the ECHO system is an ACE (Active Cabinet Exhaust) unit which sits on top of the server cabinet, drawing precisely the right amount of hot discharge air from the servers and rejecting it away into the ceiling void, without any impingement into the IT environment. The air is ducted directly to an Airedale ECHO CRAC unit which in turn is linked to one or more Airedale ECHO freecooling chillers via interactive controls logic and intelligent software. This smart, controls logic, matched with all the latest technology direct drive EC fans and chilled water coil technology, is key to the ECHO’s ability to communicate from rack to chiller and gives the ECHO system its intelligence, high efficiency and resilience. Key benefits at a glance > Outstanding energy efficiency providing reduced operating costs and carbon impact > Variable rack load densities to a maximum of 20kW per rack > No chilled water/refrigerant connections at the rack or in the IT space > The Airedale ECHO CRAC unit does not overcool as airflow demand is communicated via the ACE and the rack demand > Control is led from rack level, rescheduling the Airedale ECHO CRAC and free-cooling chiller to optimise performance > The use of thermal inertia in the room in the event of ACE failure means no rapid overheat > Higher density cabinets can be designated as the technical space is populated, rather than at day one > The entire technical space is at the server inlet temperature, thus avoiding hot spots and providing a buffer of cool air in the event of failure > With no hot/cold aisle configuration, the technical space available for IT equipment is increased Example ECHO application: PUE 1.2* + Airedale ECHO CRAC unit + Airedale ECHO free-cooling chiller Airedale ECHO Monitoring & Control System (EMCS) * Live data centre - details on request

ECHO: Space-saving and operationally-friendly The ACE combined with the Airedale ECHO CRAC unit creates a temperature neutral environment that intelligently measures and provides the air volumes demanded by each individual rack. Because the hot discharge air from the servers is managed, there is no re-circulation into the IT space eliminating the need for any hot aisles. This allows the optimum utilisation of data hall floor space. ECHO system: Typical operating parameters Since the Airedale ECHO CRAC unit provides the primary heat transfer of the cooling system, the ACE is completely dry,...

Looking forward - as your data centre grows By installing the ECHO cooling system, it is possible to future proof the data centre such that it can operate at low, medium and high densities. The system also allows a uniform heat load density per cabinet that can be altered over the life cycle of the data centre, so there is no need to stipulate high density cabinet positions from day one.
