Purdie Building Laboratory Equipment Cooling

Tender description

The University of St Andrews (UoStA) has commissioned works in order to eliminate cold water consumption by various laboratory instruments throughout the Purdie Building (School of Chemistry). This project will see the introduction of a new closed circuit chilled water installation to provide the necessary cooling to the laboratory instruments, thus negating the need for the mains/boosted cold water supplies. The chilled water circuit shall serve a number of wall mounted cooling interface units (CIUs) within each laboratory, which will provide hydraulic separation from the instruments being cooled. The existing cold water supplies which were previously utilised for cooling purposes, shall be stripped out or modified where necessary, so that they can be utilised for pressurising the chilled water circuit loops as and when required. As these circuits will now be used on an occasional basis, provision shall be made where required, to prevent stagnation of the relevant pipework circuits by the use of solenoid valve activation in conjunction with the proposed new BMS installation. The completed chilled water installation shall eliminate water consumption for equipment cooling within the following laboratories: * Room 118 * Room 234 * Room 325 * Room 417 * Room 425 Lot 1: The University of St Andrews (UoStA) has commissioned works in order to eliminate cold water consumption by various laboratory instruments throughout the Purdie Building (School of Chemistry).
