Optimisation is a crucial aspect of the role of an engineer whereby design constraints and criteria are assessed via a systematic process in order to provide the maximum achievable value. An aromatic oil processing company approached Heat Exchangers WA a short time ago with cooling tower inefficiency and heat exchanger fouling problems. Since then our cooling tower and plate heat exchanger divisions have been working in a team closely with the client to not only provide the required heat transfer but additionally assist in optimising the design and processing functionality of the plant. Additionally, our engineers designed the entire plant heat rejection system, which involved a network of cooling towers and plate heat exchangers to cooling and condense process steam before cooling water to a final workable temperature. Your calls for help are what drive us, service is our passion. We just happen to sell great heat exchangers.
A total of twelve gasketed plate heat exchangers have been supplied to the client with a further two currently being assembled to allow for the client to increase their production capacity. The heat exchangers are designed with stainless steel (316 L) plates and Viton gaskets (Gaskets that are phthalate free in order to prevent it from being absorbed into the oil). Furthermore, three MTT Evapco cooling towers replaced less efficient towers in order to meet the required cooling whilst providing ultimate corrosion protection due to its fibreglass construction material. The production of aromatic oils can unfortunately produce severe scaling with a potential for blockage, therefore Heat Exchangers WA provide regular servicing as an effective preventative measure to various operating aromatic oil production plants throughout Western Australia.
Heat Exchangers WA in conjunction with the Triple M Group have supplied the air-conditioning process equipment at the expansive Capital Square development in Perth City for Woodside Energy. The Capital Square development was a monumental contract for Heat Exchangers WA in terms of the package size containing both Plate Heat Exchangers and Cooling Towers that were delivered to the client. Furthermore, the equipment was fitted in a mid-level plant room increasing design and installation complexity, requiring Heat Exchangers WA to not only provide the required heating and cooling capacity but also adhere to the architecturally aesthetic preferences.
Within multi-storey buildings the number of floors relates to the lettable space available and as a result the overall profit of the landlord. Cooling towers are of immense height, therefore, reducing the number of floors that can be constructed. A low profile forced draft Evapco cooling tower was selected, effectively decreasing the height of the tower from 4.5m to 2.7m and thereby its impact upon the number of floors that can be constructed. Our sales engineers ensure that the client is delivered the most effective and efficient cooling solution required in order to increase the rate of return.
A total of eight Evapco LPT forced draft cooling towers were delivered to the Capital square development. Additionally, eight sizeable Gasketed Plate Heat Exchangers were provided in order to deliver a total of 9000 kW at 1°C LMTD thereby allowing maximum heat transfer area. Gasketed Plate Heat Exchangers were utilised to enable heat transfer whilst preventing cross-contamination by separating the water from the chiller and cooling towers. This separation is crucially important due to the exposure of water running through to the cooling towers to the ambient, which can cause fouling and scaling to occur within the chiller process equipment.
It is a beautiful sunny winter’s day here in WA! Heat Exchangers WA just replaced another older forced draft condenser with a sparkling brand new Evapco CATC induced draft Evaporative Condenser. This included all the bells and whistles, such as Thermal-Pak II Coil, superior efficiency drift eliminators and the patented motor swing out arm plus davit providing unprecedented maintenance access and inherently better operation. Additionally, the Evapco condensers arrive pre-built allowing the minimisation of your on-site assembly costs.
Are you aware that by installing a newer model condenser you can save significantly on electricity costs and reduce environmental impact?
One of our food processing clients saved the equivalent of 5 household’s annual electricity consumption! By replacing their older, less efficient condenser with a new 11 kW Evapco CATC induced draft Evaporative Condenser they were able to achieve the same required output at a far cheaper cost, saving both their money and our environment.
Is your current heating and cooling equipment getting a little tired and as a result has an out-dated power consumption? Is it costing you unwanted operational and maintenance costs? It could be time for an upgrade. Here at Heat Exchangers WA we pride ourselves on exceptional service and commitment to the client, our cooling tower division designs each product to meet your required specifications the most effective and efficient way possible. Just ask our food processing client, they loved their first Evapco condenser so much they wanted two more, hopefully we can connect four!
Heat Exchangers WA recently replaced an older forced draft condenser with a new Evapco CATC induced draft unit. The induced draft counterflow condensers are designed for easy maintenance and long, trouble-free operation.
Hello Sunshine! Here at HEWA we love sunny days, primarily because it means plenty of solar gain on our 400 125W panels! This means big savings on our power bill (as you can see here in the pictures) which in turn means added savings for our customers. Ask yourself this, “What commitment is your current supplier making to reduce their carbon footprint?
Meet Rod, a now happy octopus fisherman from Busselton Western Australia. HEWA recently received a distressed phone call from Rod who had recently dropped 1200 occy traps and suffered engine PHE problems on the return trip home. Rod was battling to find parts and his biggest fear was the octopuses starving to death in their traps! HEWA’s experts identified the rare part type and could immediately supply getting Rod back on the water within days, not weeks. Does your current provider have you covered for unforseen circumstances?
Keeping up with the maintenance of your Heat Exchanger. Like all equipment, for it to perform at it’s best, it needs to be serviced to ensure it’s performance and lifespan. Heat Exchangers WA can inspect your Plate Heat Exchanger and make sure it’s working to it’s full potential. Whether it be chemical cleaning and UV crack testing your plates, replacing your gaskets or a full refurbishment, we can help. Regular cleaning of your PHE’s ensures efficiency and reliability of your equipment. For a full list of our services check out our website.
Brazed Plate Heat Exchangers (BPHE’s) are among the most efficient heat exchangers on the market.
On an upcoming project in Perth’s CBD, a client has decided to sou to source BPHE’s as they occupied 20% less space than a traditional plate & gasket heat exchanger.
BPHE’s traditionally are thin stainless plates with narrower channels (giving a higher heat transfer co-efficient), pressed together with copper sheet and brazed in an autoclave at extreme temperatures.
BPHE’s are advantageous as they can operate at higher temps and pressures than plate and gasket and have a smaller footprint. They do however require very clean liquids passing through them due to limitations in serviceability as they cannot be pulled apart.
Heat Exchangers WA are delighted to supply two of our biggest BPHE’s to date in a relatively small market such as Perth.
Heat Exchangers WA completes the replacement & upgrade of a 2nd bank of Evapco cooling towers at UWA’s Central Plant. Each cooling tower cell rejects over 4500 kW of heat, supplying cold water to equipment that cools buildings throughout the campus.
