Core4 Launches Data Center Cooling Systems

Core4 Systems, Inc., a developer of data center cooling solutions, has introduced its next-generation computer room air-conditioning (CRAC), air-handling units (AHU) and chiller systems.

Designed to accommodate today's $6 billion retrofit and new construction data center markets, Core4's new systems deliver the most cost-effective and sustainable data center cooling solution in the industry, according to a June 22 company press release.

Data centers are among the largest energy consumers, devouring 61.4 billion kWh in the United States alone. According to the U.S. Environmental Protection Agency, data center energy consumption is forecast to nearly double to 120 billion KWh by 2011, which would make the data center industry the single largest user of energy. This energy consumption rate is forecast to continue doubling in the next five years. Typically, 40-60 percent of this annual energy spend is consumed by cooling systems for IT equipment.

"As a regional ISP and co-location data center operator, we are expanding our occupancy by 100 percent and this has forced us to significantly improve the efficiency of cooling our data center operations," said Dane Jasper, CEO with "By replacing our incumbent Liebert CRACs with Core4 systems, we've cut our cooling-related energy consumption by an astounding 72 percent, have been approved for a $153,000 rebate from PG&E, are saving more than $11,600 per month, and have cut our power utilization efficiency (PUE) rating from 1.82 to 1.25 without sacrificing our temperature or humidity control."

The company's new solutions also reduce water usage at data center facilities at regional power plants. A typical 100-ton water-cooled data center consumes 1.2 million gallons of water per year at the onsite facility. This can double depending on cycle concentration rates in cooling towers. Consequently, a 100-ton data center consuming 1.7 million kWh per year for cooling on average requires 3.2 million gallons of water for the cooling load at the power plant. With a Core4 data center-cooling infrastructure, water consumption can be drastically reduced to 900,000 gallons at the power plant per year due to the total energy savings.
