IT Cooling


Echo™2kW - 20kW

  • Chilled Water
  • EC Fan

The high efficiency ECHO IT Cooling System 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 free cooling chillers via interactive controls logic. 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.

Units within the range are exempt from Ecodesign when applied in process cooling applications (i.e. data centres). Please refer to your Airedale account manager for full details


  • Outstanding energy efficiency reducing operating costs and CO² impact
  • 67% energy saving compared with a conventional downflow system
  • 50% less air volume, using less power by varying the air volume
  • Up to 95% free-cooling per annum


  • Control is led from rack level, rescheduling the Airedale ECHO CRAC and free cooling chiller to optimise performance
  • Higher density cabinets can be designated as the technical space is populated, rather than at day one
  • With no hot/cold aisle configuration, the technical space available for IT equipment is increased


  • n + 1 fans for complete confidence
  • The Airedale ECHO CRAC unit does not overcool as airflow demand is communicated via the ACE and the rack demand
  • The use of thermal inertia in the room in the event of ACE failure means no rapid overheat
  • 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


  • Variable rack load densities to a maximum of 20kW per rack
  • Higher operating temperatures allow for more free cooling, more of the year
  • Ensures correct air quantity, temperature and pressure is fed to server inlet
  • No chilled water/refrigerant connections at the rack or in the IT space
  • Control is led from rack level, rescheduling the Airedale ECHO CRAC and free-cooling chiller to optimise performance
  • Pressure differential management so ACE fans mirror the server fans
  • Eliminates hot spots
  • With no hot/cold aisle configuration, the technical space available for IT equipment is increased
