Black and white silver gelatin photograph taken by Wolfgang Sievers features the evaporative water cooling towers, part of Building 11, Power House, at the Kodak Australasia Pty Ltd factory complex in Coburg, 1964.
The Marley evaporative water cooling towers were located above the Machinery Hall along with the North Annexe and two concrete water tanks.
The Power House Building 11 at the Coburg Factory consisted of an integrated Machinery Hall with its north and south Annexes, Boiler Hall, evaporative water cooling towers, 62 metre brick chimney stack, oil bunkers, tank farm and office/amenities block.The fully integrated Power House provided the most efficient use of electricity and fuel oil (and later natural gas) to match the variable load of the factory. For its time in the early 1960s, this plant represented best practice in engineering design, construction and use of energy conversion.
There were three separate evaporative water cooling units within the one tower structure, each with its centrifugal fan and venturi outlet and racks of louvred timber over which the water was sprayed for air cooling. Under certain seasonal conditions there was sufficient redundancy in the cooling capacity to allow each unit to be serviced separately. These towers provided cooled water for the turbine and refrigeration condensers at up to 800 litres per second.
The North Annexe of the Machinery Hall contained fire pumps for the factory sprinkler systems and some of the compressors for both compressed air and ethylene-glycol (brine) refrigeration. The brine refrigeration system used three screw and two multi-cylinder reciprocating ammonia compressors circulating brine at an outgoing temperature of -9ºC. These five units totalled 2.1 MW to service chill rooms, low dew-point drying and emulsion chilling, and to cope with summer load conditions. Compressed air supplied from four compressors was circulated throughout the factory at 550 KPa up to 1150 litres per second. These were all non-lubricated units using dry carbon or teflon piston rings and seals so that the compressed air was free from any contamination.
Large quantities of treated and clarified water was used in the manufacturing areas particularly in emulsion and photochemical operations. Incoming mains water was first stored in two 450,000 litre tanks maintaining continuity of supply; it was then passed through sand filters and stored in tanks for immediate use or for further chemical treatment and subsequent storage in the tank farm area north of the North Annexe. Large quantities of distilled water was used in emulsion making and testing. This water was distilled to a purity of 0.3 microsiemens in two triple-effect stills (and later in reverse-osmosis filters) located in the Machinery Hall. With a total production capacity of 2300 litres per second this water was stored in a 27 kilolitre stainless steel tank and reticulated throughout the factory in Pyrex glass piping.
All of this plant was in use until the factory closed in 2004.
Wolfgang Sievers is widely recognised as one of Australia's most significant architectural and industrial photographers. He pioneered a modernist photographic style influenced by the Bauhaus, and his work celebrates industry and the worker. Sievers was commissioned to document the newly constructed Kodak Coburg plant. He subsequently took several hundred black & white and colour images that highlighted the modern architectural and industrial design features of the complex.
Kodak manufactured and distributed a wide range of photographic products to Australasia, such as film, paper, chemicals, cameras and miscellaneous equipment. Its client base included amateur and professional photographers, as well as specialist medical and graphic art professionals who used photography, x-ray and other imaging techniques.
This photograph is part of the Kodak collection of products, promotional materials, photographs and working life artefacts collected from Kodak Australasia in 2005, when the Melbourne manufacturing plant at Coburg closed down.
