Lowe’s Companies, Inc. has 1,840 retail home improvement and hardware store locations across the United States. Cleary Zimmermann Engineers provided Commissioning service for the company’s San Antonio Data Center.
Cleary Zimmermann's Commissioning Division performed field installation verification, TAB, and operational performance testing of five new CRAC (computer room air conditioning) units serving an existing data center floor. We also commissioned the addition of six new 300KVA, 575V;120/208V transformers and the associated RPPD’s feeding existing RPP’s on the Data Center floor. and verified the performance of the new equipment with the application of load banks to the RPP’s. We performed commissioning and load bank testing of a new 2000kW, 575V Caterpillar diesel generator and the associated ASCO paralleling switchboard section. The generator serves as one of three backup generators for the entire site’s electrical system. The future installation of a fourth generator is planned. Our team also commissioned a new Trane air cooled chiller (CH-3), Fuel Polisher and Underground Storage Tank pumps and controls associated with Generator 3 in the South Plant. The intent of the functional performance testing is to verify the sensors, lead/lag control of pumps, and alarm conditions outlined in the sequence of operation.
