Adams, Subsidiary of Service Filteration Corporation, All Rights Reserved, Removable tube bundle for easy inspection or replacement, cleaning, U-Tube fully relieves stress effects from thermal expansion and contraction, No packing required to isolate the two fluids, Shell side Can be flooded with Ammonia as cooling media, Design Temperature: available at a wide range of low or high temperatures; consult factory. In some cases there can be more than one solution. Following three TEMA types of fixed-tubesheet heat exchangers can be made 3. There is no chance for external fluid leakage, and no packing required to isolate the two fluids. R.P. info@rpadams.com | Tel: (716) 877-2608  | Fax: (716) 877-9385  | Toll Free: 1-800 896-8869. Adams tubular heat exchangers meet TEMA and ASME Section VIII, Division I code requirements. The AKU Kettle Type Series Heat Exchanger includes a removable U-tube bundle, stands up well to stress, and the shell side can be flooded with ammonia as cooling media. Both side process streams (not utility) One stream process fluid and other is steam or hot oil: One stream is a condensing vapour and the other stream is cooling water or air. A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. AF Series Heat Exchangers – TEMA Type BEM, BEL, NEN. Shell side only. Plate Heat Exchanger is a device that works with principle of two different liquids making heat transfer in them without contacting each other, through a gasketed metal plates. Full technical advice can be given by a heat exchanger applications engineer. Heat Exchanger Heater Condenser Chiller Re boiler; One stream process fluid and the other is water or air. The manufacturer must then consider all the thermal and mechanical requirements of the requested design code when making the selection. Figure 1 illustrates a typical unit that may be found in a petrochemical plant. Adams fixed Shell and Tube Heat Exchangers are available in a wide range of materials of construction including carbon steel, stainless steels, admiralty brass, and cupro-nickels to name a few. Adams can supply units having wide range of shell diameters, gas flow capabilities and liquid flow rates. Whitepaper - Guide to the right TEMA Exchanger (en-GB), Tubes can be leaned internally by rodding, Non-hazardous liquids & gases below 40barg, Non-hazardous liquids & gases above 40barg, Fixed tube sheet, channel integral with tubesheet. From the three-letter coding for each type of exchanger (AEW, BEW, AEP and so on, as listed in the table) a picture can be built up of the final shell-and-tube assembly of front-end stationary head, shell type, and rear-end head Adams can supply units having wide range of shell diameters, gas flow capabilities and liquid flow rates. The AKU Kettle Type Series Heat Exchanger includes a removable U-tube bundle, stands up well to stress, and the shell side can be flooded with ammonia as cooling media. Straight Tube and Fixed Tubesheets Examples such as BEM, AEM, NEN, etc., This TEMA type is the simplest design and is constructed without packed or gasketed joints on the shell side. I well recall in my earlier years as a junior applications engineer, my mentor of the time showing me how to make a selection, saying that the enquiry we were looking at ‘was leading him by the nose’ to a certain type of heat exchanger design. Tube side only. There is no chance for external fluid leakage, and no packing required to isolate the two fluids. Adams P.O. The standard plate heat exchanger has 4 in-out ports (two of them for the hot side, and the other two ports for the cold side circuit). Adams, Subsidiary of Service Filteration Corporation, All Rights Reserved, No packing required to isolate the two fluids, Can be used for hazardous or flammable gasses or liquids, Design Temperature: available in a wide range of low or high temperatures; consult factor. All the types shown in the table can be designed in accordance with TEMA B, C and R codes. From the three-letter coding for each type of exchanger (AEW, BEW, AEP and so on, as listed in the table) a picture can be built up of the final shell-and-tube assembly of front-end stationary head, shell type, and rear-end head, L - Fixed tubesheet like “A” stationary head, M - Fixed tubesheet like “B” stationary head, N - Fixed tubesheet like “N” stationary head, Copyright © 2020FUNKE Wärmeaustauscher Apparatebau GmbH. Probably the most commonly used in our industry. The table is intended as a general guide only and does not purport to cover all aspects of design. The decision as to which class of TEMA to use does not lie with the heat exchanger manufacturer, but with the design authority responsible for that part of the project. But how do we decide which design of heat exchanger for a given application will satisfy the operating conditions, all the mechanical/thermal criteria, and give a cost-effective solution? Adams can supply units having a wide range of shell diameters, gas flow capabilities and liquid flow rates. The advent of modern computer programmes has enabled many of us to thermally rate heat exchangers quickly and accurately. The AF Series Heat Exchanger is ideal for hazardous or flammable gasses or liquids.
