Prompt action by Green Point UK, BITZER UK's compressor remanufacturing and services arm, ensured critical cooling at a major UK data center was maintained following the failure of several chillers at the site.
The loss of cooling capacity meant the data center was vulnerable to a spike in ambient temperatures or an increase in the intensity of server usage, which could have overloaded the remaining cooling plant at the site, with potentially catastrophic consequences.
proactive approach
Will Pribyl, General Manager of Green Point UK, said, "Due to system issues, several chillers on site had gone down and the data center was vulnerable. The work needed to be done immediately to ensure continuity of cooling, and the on-site contractor was under pressure to solve the problem."
The company was contacted due to its proactive approach and ability to guarantee the remanufacture of compressors regardless of their mechanical and electrical condition once units have been stripped down.
data center cooling optimization
The company upgraded the compressors to the latest BITZER specification improving efficiency
Green Point UK fast-tracked full strip-down and remanufacture of five BITZER CSH95111 and CSH95113 semi-hermetic screw compressors, which are optimized for data center cooling and use in air-cooled liquid chillers in UK conditions.
As part of the remanufacturing process, the company upgraded the compressors to the latest BITZER specification, improving efficiency and ensuring compatibility with current-generation spare parts.
contactless oil-level monitoring
The upgraded compressor has the same footprint but includes internal enhancements, including the replacement of the original float-type oil-level management control with an optical sensor for improved performance.
The optical system provides contactless oil-level monitoring, ensuring the compressor has optimum lubrication at all times.
energy performance and reliability
Will Pribyl adds, "The upgrade effectively took what were first generation units up to the same specification as BITZER's latest third generation units, improving energy performance and reliability, and ensuring spare part support for the foreseeable future."
Green Point UK is supporting the contractor in improving the resilience of other data center facilities it is responsible for, including the use of monitoring via the BITZER Digital Network and reducing running costs with variable speed drives.
