Eaton-Williams Targets Energy Savings with High Density Cooling Solutions at Data Centre World Expo

Eaton-Williams will be featuring cooling solutions that are ideally suited to high performance computing environments at the Data Centre World Expo 2015 to be held at ExCel London on 11-12 March.

With rising energy costs and stringent regulations shaping the design and implementation of cooling technologies, all of Eaton-Williams products are designed for optimum energy efficiency, thereby helping customers to reduce their energy usage, costs and Power Usage Effectiveness (PUEs) whilst addressing environmental concerns.

On Stand G25, Eaton-Williams will be show-casing its offerings targeting high density data centre applications, which include:

  • Active rear door heat exchanger and micro channel rear door
  • CDU (Cooling Distribution Unit)
  • Fan assisted and angled floor grilles

Eaton-Williams rear door heat exchangers (RDHx) provide 100% heat rejection at source, delivering up to 65kW of cooling per rack. Eaton-Williams offers active, passive and micro-channel rear doors to suit project specific requirements.

The Cooling Distribution Units (CDUs) can deliver close controlled water cooling for up to 20 rear door heat exchangers. The CDU can deliver up to 305kW of cooling using only 4kW of power and offers N+1 reliability. When two CDUs are used in tandem, they can provide Tier 4 resilience.

With hot spots a key concern in data centres, Eaton-Williams can provide a solution in a range of floor grilles, including its new angled grille and innovative, fan assisted floor grille which directs cool air to the rack where it is most needed. The fan assisted floor grille replaces standard floor tiles and offers plug-and-go connectivity.

Common controls

Eaton-Williams offers a common controls platform across its range of CDUs, Computer Room Air Conditioner (CRAC) units and data centre systems. These controls are built around a 32-bit RISC microprocessor with large memory capacity and offer multi-protocol support including HTTP/HTTPS/SSL, SNMPv2 and SNMPv3, SMTP, FTP, CLI (Command Line Interface), Modbus® IP and BACnet® IP. These communication options allow easy integration with any Building Management Systems (BMS), Network Management Systems (NMS) and Data Centre Infrastructure Management (DCIM) System.

A full colour, interactive touch screen display provides users with convenient and complete control at their fingertips.
