Industrial Air Conditioning, Ventilation & Refrigeration
Western Australia’s newest power station which is situated in the Industrial park of Kemerton, just North of Bunbury, Western Australia (WA) is a 300MW gas turbine and is the first stand-alone peak-load power station to be built in WA. It was constructed by Siemens Australia and is owned and operated by Transfield Services.
The power station has twin 35 metre-high, 6.5 meter-diameter stacks designed to disperse high-temperature exhaust gas from the gas turbines.
Diamond Industries was involved in this high profile power station, and the contribution has been the environmental systems providing full air conditioning to office areas and the main control room the heart of this complex, with 100% redundancy backup to ensure control equipment and staff never “feel the heat”.
The two (2) turbine halls have been provided with massive exhaust systems capable of exhausting all the air in these halls at twelve (12) times per hour. The main fans have three (3) levels of redundancy ensuring continued operation of this critical plant at all times.
With the new Life Sciences Building (B300) project, east of Buildings 304, 305 & 306, planned to commence in early 2005, a number of new services including chilled and heating water supply pipes for air-conditioning had to be designed, tendered and installed prior to the commencement of this building project. No chilled and heating water existed in this part of the campus.
Curtin University awarded Diamond Industries two stages of the contract for the extension of underground chilled and heating water piping infrastructure at the Bentley Campus.
To cater for existing, new and future buildings, the pipes were sized accordingly with 375mm blue UV-PVC being used for the chilled water pipes and 300mm insulated steel, with victolic couplings for the heating pipes. Because of the large number of existing services crossing the route of the new work, the pipes were also installed deeper than in previous installations, up to 3.5 metres.
The pipes run from the basement plant room of Building 408 to Building 311,
with a total length of over 1000 metres.
Alcoa’s Pinjarra alumina refinery is located 6 kilometres east of the rural town of Pinjarra, about 90 kilometres south of Perth. It is situated in the Shire of Murray in the Peel Region of Western Australia’s South West. Pinjarra is one of the most successful and cost efficient alumina refineries in the world and currently produces about 7 per cent of the world’s alumina
This upgrade allows the Pinjarra refinery to:
O’Donnell Griffin awarded Diamond Industries the contract for the process cooling systems for eleven (11) electrical sub-stations as a part of the Pinjarra refinery upgrade project. These electrical sub-stations house essential electrical equipment and have been fitted with direct expansion air conditioning equipment to ensure their safe and efficient operation.
The Water Corporation is taking a ‘security through diversity’ approach to ensure our water future, through the Perth Seawater Desalination Plant. The project will provide an extra 45 gigalitres of water each year. This will make it the biggest single water source feeding into the Integrated Water Supply Scheme, which provides 1.5 million West Australians with their water.
The desalination plant is the biggest of its kind in the southern hemisphere and is located at Kwinana W.A. Multiplex Degrémont Joint Venture (MDJV).awarded Diamond Industries the contract for the mechanical services to the nine (9) buildings which make up this prestigious project, the first of this magnitude in Australia.
The scope for Diamond Industries is diverse ranging from traditional air conditioning to the office / administration building through to pure process cooling and ventilation for switch rooms, pumping stations, hazardous substance storage areas and reverse osmosis switch room.
The main air conditioning units provided are direct expansion water cooled packaged units, for process and switch room areas. Special water cooled “Variable Volume Refrigerant” (VRV) units for the administration building. Both systems utilise the reticulated process cooling water ring main for heat rejection. Control is provided by stand alone PLC systems in each building, connected to the site wide optic fibre supervisory system.
