The Alfa Laval brazed heat exchanger

The Alfa Laval BHE is the original brazed plate heat exchanger. The BHE concept is a variation of the traditional plate and frame heat exchanger, but without gaskets and frame parts. The BHE simply consists of channel plates, two cover plates and connections. All including parts are made of stainless steel material.

• Compact and tough• Easy to install• Cost efficient

MaterialThe brazed plate heat exchanger (BHE) consists of thin corrugated stainless steel plates which are vacuum brazed

together using either copper or nickel as the brazing material. In HVAC applications copper brazed units are most frequently used, while nickel-brazed units are preferred in for example food applications and in applications involving aggressive fluids.

DesignBrazing the stainless steel plates together eliminates the need for sealing gaskets and thick frame plates. The

brazing material seals as well as holds the plates together at the contact points. Alfa Laval’s brazed heat exchangers are always brazed at all contact points, which ensures optimal heat transfer efficiency and pressure resistance. The plates are designed to achieve longest possible lifetime.

Since virtually all material is used for heat transfer the BHE is very compact in size and has a low weight and a low hold-up volume. Alfa Laval offers a flexible design that can be customised to meet the customers’ specific requirements. The brazed plate heat exchangers from Alfa Laval ensure the customer the most cost-efficient solution to his heat transfer duties.

• First class manufacturing facilities• High and consistent quality• Leak and pressure testing of all units before delivery

Flow principleThe basic flow principle in a brazed heat exchanger for HVAC applications is parallel and counter current flow to achieve the most efficient heat transfer process. In a single pass design all connections are located on one side of the heat exchanger, making installation very easy.

MultipassThe design options of the brazed heat exchanger are extensive. The heat exchanger can be designed as a mul-tipass unit, different types of connec-

tions are available, and there is also the option of choosing the location of the connection. Alfa Laval offers a wide range of standard heat exchanger models and sizes tailor-made for HVAC applications which are available from stock, but customer specific designs can of course also be offered when requested.

Mix proof designIn applications where legal regulations or other reasons call for extra security, Alfa Laval’s patented double wall design for brazed units could be used. When using double walls the two media are separated by two stainless steel plates. In the unlikely event of an internal leakage it will be visible on the outside of the heat exchanger and no mixing of the two fluids will occur.

Applications

ApplicationsBrazed plate heat exchangers are com-monly used in all types of heating applications with demands on comfort, reliability and safety. Heating, in most cases, is a matter of providing a com-fortable indoor environment, whether at home, at work or in a public facility. It can also involve heating tap water, swimming pools, greenhouses etc.

Heating and District HeatingGeneral heating applications are often divided into heating and district heating, based on several major differences. Heating systems normally have the heat source inside the building and supply heat to a single building. The heat is normally provided from a boiler, but it can also come from heat pumps and solar panels. In contrast, district heating systems distribute hot water or steam to multiple buildings. The heat can be provided from a variety of sources, including geothermal sourc-es, co-generation plants, waste heat from industry, and purpose-built heating plants. Whether it is heating or district heating, the BHE has its natural place in the system.

Tap water heatingThe advantages of using a brazed plate heat exchanger to produce hot tap water compared to traditional coil in tank systems are numerous. The BHE instantly heats the tap water to the required temperature when it pass-es through the heat exchanger. This means that hot water is available imme-diately and at any time. Another benefit with using plate heat exchangers for hot tap water production is that the system requires much less spaces than a traditional tank and coil system. If solar energy is used to produce hot tap water a BHE makes it possible to separate the treated water in the solar panels from the tap water circuit. Also, scaling problems and corrosion risks in the solar panels are reduced when sep-arating the circuits with a BHE.

The compactness of the BHE makes them easy to install in district heating modules, both in large and small capacity systems.

The small hold up volume means that the tap water heater is easy to regulate and provides instant hot water.

Accessories

InsulationThe heat exchanger insulation is easily assembled and dismantled. The Alfa Laval insulation provides protection from the heat pack and the climate in the operating room will be dry and not too hot. The insulation material used for most models is polyurethane, which has a thermal conductivity of 0,031 W/mK. Depending on the temperature require-ments two types of insulation are avail-able for most models, max 110ºC and max 140ºC.

Feet and mounting bracketsCB26 and larger units can be delivered with feet or mounting brackets. These make the installation work easier and minimise stresses in the connected pipes. The unit can also be bolted to the floor. CB26, CB27, CB51 and CB52 can be wall mounted using the standard feet frame. CB200 and CB300 are always supplied with feet and a lift-ing hook to ensure safe and functional installation.

Couplings for welding or solderingThe couplings fits on the threaded con-nections of the units. Future service is then easy made by dismantling the heat exchanger from the pipes via the cou-plings. This connection is approved in most countries when weld or flange connection is required. A flat washer is used as sealing between the coupling and connections.

Cleaning-In-Place (CIP)All types of heat exchangers need to be cleaned regularly to remove deposits such as scale, sludge and microorgan-isms. Alfa-CIP is a convenient solution that carefully removes the deposit on all heat transfer surfaces in the heat exchanger. Alfa-CIP 75, 200 and 400 are constructed in stainless steel using high quality components (pumps, valves etc.) according to ISO 9001 and with the CE-mark. The smaller units Alfa-CIP 20 and 40 are made of industrial grade plastic. Alfa-CIP is mobile due to its compact design. The units have revers-ible flow, and Alfa-CIP 75, 200 and 400 also have a built in heater. All cleaning detergents used by Alfa Laval are envi-ronmentally friendly and do not damage the equipment.

Instructions

Installation instructionsIn HVAC applications it is from a per-formance point of view recommended to install the heat exchanger so that a counter current flow is obtained. It does not matter if the heat exchanger is mounted vertically or horizontally, as long as no change of phase takes place (evaporation/condensation). If drainage of the heat exchanger is needed for some reason, please take this into con-sideration when positioning the heat exchanger. The heat exchanger can be mounted with brackets or standing on feet supplied by Alfa Laval. It is impor-tant to minimise vibrations or pulsations from being transferred from the pipes to the heat exchanger. The usage of flexible hoses is one way of reducing stresses caused by vibrations, and stresses from the piping system.

OperationAdjustments in flow rates to maintain correct temperatures or pressure drops should be made slowly in order to pre-vent pressure shocks to the system. Therefore fast closing valves should not be used unless the pipes in the sys-tem are very short. Any problems with keeping the performance of the heat exchanger may be caused by changing temperature conditions, changing flow rates or by fouling.

Maintenance instructionsThe heat transfer through the plates can be seriously reduced by the formation of deposits of various kinds on the plate surfaces. Even if the highly turbulent flow gives a strong resistance to the for-mation of deposits the turbulence can not completely eliminate fouling. Thanks to CIP (Cleaning In Place) it is possible to remove calcium deposits and other forms of scaling from the plate surfaces in an easy and effective way. Different cleaning solutions can be used depend-ing on the type of deposits. Alfa Laval has a world-wide service organisation. Service is available in 130 countries at 15 major service centres and a network of service stations around the globe.

Start up procedure

1. Before starting any pump, check whether instructions exist stating which pump should be started first.

2. Check that the valve between the pump and the heat exchanger is closed.

3. Check that the valve at the exit, if there is one, is fully open.

4. Open the ventilation.

5. Start the pump.

6. Open the valve slowly.

7. When all the air is out, close the ventilation.

8. Repeat the procedure for the other side.

Shut down procedure

1. First establish whether instructions exist as to which side should be stopped first.

2. Slowly close the valve con-trolling the flow rate of the pump you are about to stop.

3. When the valve is closed, stop the pump.

4. Repeat the procedure for the other side.

5. If the heat exchanger for any reason is shut down for a longer period, more than a few days, it should be drained.

Using webcALcTM

webcALcTM is an easy to use selection tool available on-line that can be used for sizing heat exchangers for applications like tap water heating, district heating, cooling, and district heating.

• Available on www.alfalaval.com• Easy to use• Detailed results

Using webcALcTM

How to calculate and select a heat exchanger with webcALcTM

For duties that are not covered in the selection tables, and if you want to get a more tailor made design, you can design your heat exchanger on-line on the internet site www.alfalaval.com using a selection tool called webcALcTM. It should be noted that webcALcTM is a

simplified version of the software used by Alfa Laval, and therefore the result may differ slightly when comparing with the selection tables and/or quotations made by Alfa Laval representatives. webcALcTM is quite easy to use, but if you need instructions just follow the step by step instructions below. You enter the data for your fluids into the dif-

ferent input fields in webcALcTM. Move between the different input fields by using either the mouse or the tabulator.

How to use webcALcTM’s control panelDesign pressure: Select the required pressure resistance for the heat exchanger. (Default 10 bar)

Display: webcALcTM selects from the complete range of gasketed and brazed heat exchangers included in the soft-ware (default). You can specify if you only want a choice of either PHEs or BHEs or standard sizes of BHEs.

Max no. of exchangers: webcALcTM will select one or more identical units (maxi-mum 9 units) depending on the require-ment of the thermal duty (default). If you want webcALcTM to suggest only solu-tions with a certain number of identical units, then select from one unit to nine units.

After you have entered the dataWhen you have entered your data, press the heat balance button and webcALcTM will present the tempera-tures graphically. Via the heat balance webcALcTM will calculate the missing parameters (heat load, flows or tem-peratures). Heat balance will also indi-cate if any input parameters for a suc-cessful thermal calculation are missing. Please note that if both heat load and flows have been specified, webcALcTM will give higher priority to the heat load.

1. Start by selecting the hotter fluid, fluid 1, by clicking on the arrow in the pull down menu. Available fluids are: water (default value), seawater (contain-ing approximately 3% NaCl), eth-ylene glycol and propylene gly-col. When selecting glycol fill in the concentration, %, in the input field.

2. Enter the maximum allowed pressure drop over the heat exchanger in the next input field. (Default 100 kPa)

3. Enter the available flow rate of fluid 1. Omit this value if the heat load is specified either at the bot-tom of the page or if the heat load is specified through the full input on the Cold Side. There must always be heat balance in the heat exchanger, which means that the heat load on the hot side is always equal to the heat load on the cold side.

4. Enter the inlet temperature of fluid 1 in the input field temper-ature in, and if applicable the required outlet temperature in the input field temperature out.

5. Enter the data for the colder fluid, fluid 2, in the same way as for fluid 1 (point 1 to 4).

6. At the bottom of the page you select which material that should be used for the heat transfer plates. You can choose between stainless steel AISI 316 (default), stainless steel AISI 304 and tita-nium.

7. Heat load is an optional field to be used if the in- and outlet tem-peratures as well as flow rate have not been specified on either the cold or the hot side.

8. The field units makes it possible to change between SI, American or metric units.l

• Lower cost• Plug-and-play installation• Full Technical support

Press calculate to perform the thermal calculation. webcALcTM will present up to nine alternative heat exchanger solu-tions. It is possible to use the calculate button without previous usage of heat balance. Press reset to empty your input before entering new data for a new thermal calculation. The input fields will be reset to webcALcTM’s default val-ues.

How to use and interpret webcALcTM’s resultsThe heat exchanger solutions can be sorted by four different criteria: price (default sorting is based on an approximate price comparison between the different solutions), height, weight, and extension capacity. Brazed heat exchangers do not offer any extension possibility. Please note that the speci-fied weights may be slightly lower due to different pressure vessel codes and local standards. Select your solution by clicking on the unit type in the table.

Heat exchanger selection tablesThe selection tables in this catalogue enables you to find a suitable heat exchang-er model and size in a quick and easy way for a number of pre-defined duties. The duties are based on radiator and tap water heating duties which are common in some European countries where district heating is used. It is of course impossible to cover all temperatures and capacities in tables like these, but hopefully they can provide you with some guidance when selecting a heat exchanger for your duty. For a more tailor made design you can also use the on-line selection tool called webcALc, which is presented in detail in this catalogue. Of course you are also most welcome to contact any Alfa Laval representative who will be happy to assist you with a heat exchanger selection.

How to contact Alfa Laval

Contact details for all countries are continually updated on our website. Please visit www.alfalaval.com to access the information.
