Arnotts took the initiative of installing a totally new refrigeration plant as part of the replacement of R22 coolant at their Virginia factory. The new installation has at it’s heart a large concrete box housing the equipment and cooling towers on the roof. The box was designed under stringent criteria to meet the standards of FM Global Insurance and Arnotts’ WHS regulations. The project included the reticulation of kilometers of new coolant pipework around the factory, transformer and switchboard upgrades, and a new liquid gas storage facility. These elements required intense coordination in order to be compatible with the existing structural and services format throughout the factory.
