Emerson Network Power chills cloud computing

The rise in cloud computing requires new approaches and Emerson Network Power believes its latest chiller fits the bill

Data centre cooling specialist Emerson Network Power has unveiled the Liebert PCW intelligent cooling system for data centres to address the high variations in demand for cooling power found in cloud computing.

The PCW is a chilled water floor mount unit for precision cooling of data centres, claiming the most advanced features and performance in its class.

Emerson says the PCW is intended to offer IT managers the ability to respond more efficiently to changes in density, speed of heat load transfer, capacity and availability in the data centre.

The Liebert PCW cooling system features an inner aerodynamic design that Emerson says will allow businesses to reduce data centre operational costs by as much as 70 per cent.

Key to the efficiency gains is a thorough redesign of the interior of the unit to promote better air flow, combined with advanced equipment in the shape of latest generation EC fan technology, Liebert’s iCOM control system, high efficiency filters and an ultrasonic humidifier.

The firm says the emphasis has remained on simple installation and flexibility in configuration.

“The increase in stored data levels worldwide puts new and never-seen-before demands on cooling systems, exposing shortcomings of existing approaches and creating demand for better designed data centres,” says Emerson Network Power European marketing director Stefano Mozzato.

“But on-demand, at-scale access, as part of a virtualised network architecture, means that the degree of variation and rate of change of computing load can be devastating if the system is not set up to withstand it. So the Liebert PCW has been designed to cool the servers, offering the lowest possible power.”

Emerson says that while the system is designed for medium and large data centres, its modular approach means that it can also be used in small data centres and even computer rooms.

It can be applied in modules from 30 kW to over 230 kW to satisfy demand for data centres up to 6 MW. “The PCW maintains maximum availability and optimum energy efficiency while monitoring and dynamically responding to the needs of the data server at any given time,” the manufacturer says.

A key feature of the new chiller is its redesigned chassis. Engineers at Emerson Network Power studied the air flow within the floor mount unit and completely redesigned the internal components, from the coil angle to the electrical panel design.

The firm believes that optimised inner aerodynamics is a key differentiator, since it reduces airflow resistance and thus enables maximum efficiency.

In addition, the latest generation of EC fans from fan specialist ebm-papst – together with high efficiency filters brought in from the automotive sector – reduce both energy and noise levels. The technology has seven pending patents.

The PCW comes as part of Emerson Network Power’s SmartAisle cooling solution.

Key components of the system include a selection of water connections and modifications for easy handling, alignment, installation and maintenance. It also features adjustable legs and power cables with quick connectors.

To simplify installation and maintenance, the Liebert PCW is available in three different configurations, enabling a flexible set-up.

The Liebert iCOM is a smart mode control algorithm specifically developed for the cold aisle containment requirements of Smart Aisle, which Emerson says manages temperature “enabling exactly the right cooling and airflow to the servers without wasting a single watt when moving or cooling the air control unit.” Crucially, given the cost of energy, use of the control system prevents the servers being overcooled.
