PWO - Plates Coolers Brochure

The Professional ChoicePWOWater Oil CoolerOLAER PWO | Lightweight, compact and efficient water oil coolerThe PWO is a compact and lightweight water oil cooler with a high cooling capacity compared to size. This lightweight and compact water oil cooler consists of corrugated channel plates sandwiched between the front and rear cover plates. The channel plates are pressed and vacuum brazed in the same automated procedure, and with rigorous standards of quality control.The unique plate design provides high turbulent flow conditions throughout the cooler, the key to efficient cooling. This turbulent flow reduces the risk for clogging, which in turn makes this PWO virtually maintenance free.A wide number of possibilitiesThe unique design emphasizes a number of possibilities for versatile and efficient solutions. The PWO can easily be adapted to a variety of needs and special applications including seawater, aggressive oils, high pressure and high temperature applications. With a PWO water oil cooler in your system, you can be assured that the fluid in your system is working at the correct temperature, providing maximum performance and reliability in your system.PWO WATER OIL COOLER• Light and compact• Suitable for many applications• Ease of installation• Cost efficient and environmentally friendly2 www.olaer.com OLAER | PWOOlaer is a global player specialising in innovative, efficient system solutions for temperature optimisation and energy storage.All over the world, our products are working in the most diverse environments and applications.Unique designOptimal performance as well as maintenance freeOLAER | PWO The Professional Choice 3PWOComplete system for water oil coolingPWOstandard range......of water oil coolers is available in a wide number of sizes and is in general available for immediate off-the-shelf delivery. The basic material is stainless steel (AISI 316/304), vacuum brazed with pure copper. AISI 316 can be limited to the parts of the PWO that actually come in contact with fluid, i.e. the channel plates. PWO requires small hold up volumes , i.e. a lower cost and a more environmentally-friendly solution. Low installation cost allows for oversizing for future requirements or peak loadsPWOin Mo-steel......provides higher resistance vs. AISI 316 to pitting and crevice corrosion and chloride-rich fluids. PWO’s state-of-the-art brazing technology eliminates the risk of intergranular corrosion. Mo-steel can be limited to the parts of the PWO that actually come in contact with corrosive fluid, i.e. the channel plates. Typical applications for the Mo-series are in industrial applications where high chloride concentrations put high demands on corrosion resistance. Another typical application is in the pulp and paper industries that often process with chloride-rich fluids.PWOin stainless steel......free from copper. The nickel-based brazing material has increased durability to aggressive media and they can also endure higher working temperatures than normal copper-brazed PWO. PWO in stainless steel is used where the water supply is corrosive to copper. Other applications are cooling or heating of oil with a high content of sulphur, ammonia-based cooling systems where copper is prohibited as well as pharmaceutical and chemical applications where copper-brazed coolers are susceptible to corrosion from acids and bases. Another field of application is in high-temperature applications, e.g. heating of oils.PWO-M......is an extremely small PWO water oil cooler, perfect wherever compactness is crucial. The gaskets and the plates can be of various materials to ensure compatibility with the refrigerant. Even if a costlier, highperformance metal is required for the heat transfer surfaces, the front and back plates can be made of more basic materials to cut costs. The snap-in-place connections allow easy assembly and the use of different metals without the risk of weld deterioration. The PWO-M with plates made of titanium resists corrosive seawater in onboard engine coolers and applications containing de-ionized water or aggressive fluids. See separate pamphlet, which can be downloaded from www.olaer.se .PWO withdouble walled channel plates......are designed for applications where high thermal efficiency is a requirement, and the risk of internal leakage must be minimized. Thanks to excellent thermalefficiency, compactness, low weight and quick responsetime, it is primarily used in sanitary water applications,coolers for the chemical process industries, food and pharmaceutical industries and wherever required by law or other regulations.PWOfor high pressure......is designed to meet the high demands for a cooler in applications with working pressures up to 45 bar (Note: special models and configurations are available for max working pressure 120 bar). With the exception of high-pressure applications e.g. within the process industry, the PWO is perfect for use with new, high-capacity, environmentally-friendly refrigerants. The PWO’s greater heat transfer efficiency provides opportunites linked to energy-cost and environmental savings.4 www.olaer.com OLAER | PWOHeat Load (kW) B5TOil Flow (l/min)Heat Load (kW) B8TOil Flow (l/min)Oil Flow (l/min)Pressure Drop (bar) B8TOil Flow (l/min)Pressure Drop (bar) B5TOil type: ISO VG 46Oil/water flow ratio: 2/1Inlet oil temperature 60°C at ? p max 2 barInlet water temperature 20°COLAER | PWO The Professional Choice 5Heat Load (kW) B15Heat Load (kW) B10TOil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Pressure Drop (bar) B10TPressure Drop (bar) B15Oil type: ISO VG 46Oil/water flow ratio: 2/1Inlet oil temperature 60°C at ? p max 2 barInlet water temperature 20°C6 www.olaer.com OLAER | PWOHeat Load (kW) B25THeat Load (kW) B12Pressure Drop (bar) B12Pressure Drop (bar) B25TOil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil type: ISO VG 46Oil/water flow ratio: 2/1Inlet oil temperature 60°C at ? p max 2 barInlet water temperature 20°COLAER | PWO The Professional Choice 7Heat Load (kW) B16Heat Load (kW) B28Pressure Drop (bar) B28Pressure Drop (bar) B16Oil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil type: ISO VG 46Oil/water flow ratio: 2/1Inlet oil temperature 60°C at ? p max 2 barInlet water temperature 20°C8 www.olaer.com OLAER | PWOHeat Load (kW) B35Heat Load (kW) B120TPressure Drop (bar) B120TPressure Drop (bar) B35Oil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil Flow (l/min)Oil type: ISO VG 46Oil/water flow ratio: 2/1Inlet oil temperature 60°C at ? p max 2 barInlet water temperature 20°COLAER | PWO The Professional Choice 9Heat Load (kW) B56Pressure Drop (bar) B56Oil Flow (l/min)Oil Flow (l/min)We offer a lot morethan excellent coolersTogether we review all conditions, i.e. the water oil cooler performance, the working environment, type of fluid to be cooled etc. Because of our deep knowledge and long experience, we can build on previous solutions and discuss with you all feasible solutions.
