PWO Water Oil Cooler - Olaer

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 freeThe PWO is a compact and lightweight water oil coolerwith a high cooling capacity compared to size. Thislightweight and compact water oil cooler consistsof corrugated channel plates sandwiched betweenthe front and rear cover plates. The channel platesare pressed and vacuum brazed in the sameautomated procedure, and with rigorous standards ofquality control.PWO WATER OIL COOLER• Light and compact• Suitable for many applications• Ease of installation• Cost efficient and environmentally friendlyThe unique plate design provides high turbulent flowconditions throughout the cooler, the key to efficientcooling. This turbulent flow reduces the risk forclogging, which in turn makes this PWO virtuallymaintenance free.A wide number of possibilitiesThe unique design emphasizes a number of possibilitiesfor versatile and efficient solutions. The PWO can easilybe adapted to a variety of needs and special applicationsincluding seawater, aggressive oils, high pressure andhigh temperature applications. With a PWO water oilcooler in your system, you can be assured that the fluidin your system is working at the correct temperature,providing maximum performance and reliability inyour system.2 www.olaer.com

OLAER | PWOPWOComplete system for water oil coolingPWOstandard range......of water oil coolers is available in a wide number ofsizes and is in general available for immediateoff-the-shelf delivery. The basic material is stainlesssteel (AISI 316/304), vacuum brazed with pure copper.AISI 316 can be limited to the parts of the PWO thatactually come in contact with fluid, i.e. the channelplates. PWO requires small hold up volumes , i.e. a lowercost and a more environmentally-friendly solution.Low installation cost allows for oversizing for futurerequirements or peak loadsPWOin Mo-steel......provides higher resistance vs. AISI 316 to pittingand crevice corrosion and chloride-rich fluids. PWO’sstate-of-the-art brazing technology eliminates the riskof intergranular corrosion. Mo-steel can be limited tothe parts of the PWO that actually come in contactwith corrosive fluid, i.e. the channel plates. Typicalapplications for the Mo-series are in industrialapplications where high chloride concentrations puthigh demands on corrosion resistance. Another typicalapplication is in the pulp and paper industries thatoften process with chloride-rich fluids.PWOin stainless steel......free from copper. The nickel-based brazing materialhas increased durability to aggressive media and theycan also endure higher working temperatures thannormal copper-brazed PWO. PWO in stainless steel isused where the water supply is corrosive to copper.Other applications are cooling or heating of oil witha high content of sulphur, ammonia-based coolingsystems where copper is prohibited as well aspharmaceutical and chemical applications wherecopper-brazed coolers are susceptible to corrosionfrom acids and bases. Another field of application isin high-temperature applications, e.g. heating of oils.PWO-M......is an extremely small PWO water oil cooler, perfectwherever compactness is crucial. The gaskets and theplates can be of various materials to ensure compatibilitywith the refrigerant. Even if a costlier, highperformancemetal is required for the heat transfer surfaces, the frontand back plates can be made of more basic materialsto cut costs. The snap-in-place connections allow easyassembly and the use of different metals without therisk of weld deterioration. The PWO-M with plates madeof titanium resists corrosive seawater in onboard enginecoolers and applications containing de-ionized water oraggressive fluids. See separate pamphlet, which can bedownloaded from www.olaer.se .PWO withdouble walled channel plates......are designed for applications where high thermalefficiency is a requirement, and the risk of internalleakage 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 andpharmaceutical industries and wherever required bylaw or other regulations.PWOfor high pressure......is designed to meet the high demands for a coolerin applications with working pressures up to 45bar (Note: special models and configurations areavailable for max working pressure 120 bar!).With the exception of high-pressure applications e.g.within the process industry, the PWOis perfect for use with new, highcapacity,environmentally-friendlyrefrigerants. The PWO’s greaterheat transfer efficiency providesopportunites linked to energy-costand environmental savings.The Professional Choice 3
