The reason for its success is that individually engineered solutions are offered for all the customer s requirements. Axima s research and development division also ensures the transformation of technical and scientific knowledge into customer friendly products and services. Please find more information about the products and the Axima technology group on the back page. Superchill Australia Pty Ltd 100% Australian owned was formed in 1997 on the basis of the former SULZER Australia Cooling Tower Division. As a dedicated Cooling Tower company, Superchill manufactures Axima (Sulzer) cooling towers in Australia for the local market as well as its own SC Cooling Tower range. All cooling towers are completely manufactured in-house in our Dandenong (Vic) factory, to the highest quality standards. Long service life with corrosionproof high quality cooling towers The corrosion-free plastic construction guarantees high quality and a long lifespan. Thanks to the wide range of models and capacities available, there is a type that is suitable for every requirement. Wide-ranging know-how, various accessories and possibilities to extend During design and tower selection Superchill s specialists also take into consideration further details such as noise levels and water treatment. We specialise in turnkey compact units which can be integrated in transportable standard containers. These are in demand at mine sites and for emergency situations when existing cooling systems break down. The wet bulb determines the achievable cold water The decisive factor for the cooling tower capacity is the wet bulb the relationship between ambient air and relative air humidity. Wet type cooling towers can reach a of approx. 2 to 3 C above this value. In Australia, the following wet bulb s are usually used for design conditions: Sydney 24 C, Melbourne 21.5 C, Adelaide 23 C, Perth 23 C, Brisbane 26 C, Hobart 19.5 C, Townsville 27.5 C. (Source: Airah Handbook, for critical processes, Summer, 0800-1800) On the above world map the wet bulb s are indicated in 5 C steps. 2

Cooling towers save up to 97% Water Just like air, water is one of our most vital and precious resources. The economical use of this natural resource is therefore of major importance. Cooling towers are an economical and ecological way of re-cooling: up to 97 % of water can be saved compared to continuous-flow cooling. Air out Hot water inlet Water cooling systems Depending on the required cooling water we compare various systems. At cooling water s (in Australia) below approximately + 25 C generally refrigerating machines (chillers) are used and above this cooling towers. Types of cooling towers Cooling towers are distinguished according to various criteria: 1. The force of the airstream: Naturally ventilated cooling towers (natural draught cooling towers) Artificially ventilated cooling towers (mechanical draught cooling tower). Fans may be of the induced or forced draught type design. Operating principle of a wet-type cooling tower (EWK range) Fill material Ambient air in Cold water outlet 2. The relationship of the airstream to the water flow: Counter-flow cooling towers Cross-flow cooling towers Combinations of these two designs 3. Types of fill material: Open circuit cooling towers in which the water is cooled by direct contact with the surrounding air (wet-type cooling towers) Closed circuit cooling towers the medium to be cooled has no direct contact with cooling water Hybrid cooling towers a combination of open and closed systems Operating principle of cooling towers Wet type cooling towers reach s below the ambient. Significant for this is the wet bulb see page 2 for more details. Wet-type cooling towers The water to be cooled is sprayed and trickled over fill material by a water distribution system which, owing to its shape and position, guarantees high water and air contact times. At the same time, the surrounding air is drawn through the tower in counter-flow, thereby evaporating a small part of the circulating water. The heat required for this evaporation process is drawn off by the cooling water and provides the majority of the cooling capacity. The remainder of the cooling capacity is created by the convection of the warm water to the colder air. The re-cooled water collects in the basin from where it is fed back to the cooling points. The saving in terms of cooling water in comparison with continuous flow cooling can be up to 97% of the circulation water, the remainder being required to compensate for the water loss due to evaporation and bleed-off. Closed circuit cooling towers The medium to be cooled flows through a closed heat exchanger and does not come into direct contact with the surrounding air. Water is trickled over the heat exchanger by a water distribution system (secondary circuit). Dry-type coolers The medium to be cooled flows through a heat exchanger just as for closed cooling towers. Heat is removed by means of convection to the surrounding air thus allowing the system to attain cooling water s in excess of the ambient. 3

Cooling towers with long service life In-house production to a high level of quality In the assembly section the cooling towers are pre-assembled into transportable units. Spray coating of large-surface cooling tower parts made of FRP material The components are made ready for assembly A cooling tower for every application Choosing the "right" cooling tower is vital and should be based on computer analysis of the necessary criteria: cooling capacity, energy consumption and noise level. Our standard range of cooling towers covers almost all possible applications. Special models meet very particular demands for the cooling plant. Both experience and in-house fabrication are considerable advantages enabling Superchill to meet client s specific needs. Global planning On request, our project engineers will analyse the requirements, plan the details and supervise the installation, commissioning and operation. Fast installation Well and efficient planned preparatory work reduces installation time on site to a strict minimum. A vital advantage if your production plant has to be shut down during the installation phase. Factory assembly of cooling towers in our works saves time at the place of erection Years of experience in cooling tower construction In 1957 Sulzer (now AXIMA) built the first cooling tower prototype. Since then our design and manufacturing philosophy has not changed. All our cooling tower components are developed, tested and manufactured inhouse. This is the only way we can guarantee our customers a high quality, state-of-the-art product. Development and testing New product lines and one-off projects alike are developed in our design office. Existing lines are constantly revised and upgraded to optimise performance, energy consumption and operating noise levels. New research is incorporated into the cooling tower design programs and the results are subject to stringent testing on our own test stands. Reliable specifications are an essential prerequisite for the efficient planning and economical operation of cooling towers. Materials and manufacture Fibreglass reinforced polyester has proved an excellent construction material over decades of use in the manufacture of cooling towers. The material is heat resistant and practically indestructible some of our cooling towers have been in operation for over 30 years. However, the processing of large plastic components requires a good deal of specialist knowledge. In order to ensure that nothing is left to chance we have developed our own assembly line which produces finished cooling tower casings. Prompt service Our comprehensive after sales network provides a quick and efficient maintenance and spares service. We also offer a maintenance contract which ensures the regular servicing of your cooling system.

Engineering Highlights Polypropylene Fill Up to 80ºC (or 100ºC) resistant material. Tougher material than PVC, less brittle and therefore outlasts PVC. Extruded directly from molten virgin PP (not vacuum formed) into final form ensuring optimised material thickness of foil, see foil profile below. Welded Fill Blocks The foils are welded together to form a rigid block. Compared to glued blocks, welding is a permanent and much stronger bond. Above picture shows the hitech welding machine. Best available drift eliminators Our drift eliminators comply with the Australian Standards. The above shown honeycomb drift eliminator, with three changes in air direction has a drift loss of less than 0.001% Low Maintenance Our direct-coupled fans to the motor shaft, prevent problems with belt drives in the wet air stream, such as slipping of belts combined with the squeaking noise and wearing out of belts, also improving efficiency. High efficiency, low noise fans Our high performance, low noise fans are constructed using the same technology as seen in modern aerofoil design. The wing tip at the end of the blade reduces turbulence. This increases efficiency and reduces noise. Glass reinforced PP fans are also available Special Units & Bulk Air Coolers Superchill is a specialist in designing and manufacturing bulk air coolers. Purpose-built units for any location (even for underground mining) or for total mobility can be designed and built according to the customer s needs. MODUPOL module As the name implies, our MODUPOL cooling towers are made of factory completed modules. This guarantees high quality assembly and reduces site installation time. Installation of a Module The photo shows a module being lifted into place. This cooling tower is equipped with a shallow fibreglass basin which is installed over an older existing concrete basin.
