The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. The sealing between the plates is made of gaskets. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.
BaseLine is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are carefully designed and selected to achieve optimal performance. The chocolate pattern distribution is a design feature that ensures fluids are evenly distributed across the entire plate. The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided.
High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.
APPLICATION
Working at pressure up to 145 psi, Alfa Laval’s Baseline Series handles not only heating and cooling, but also pasteurization at low flow rates. These heat exchangers can be use in the cooling and heating of applications such dairy, brewery, beverage, and viscous products.
The Baseline Series heat exchanger is a competitive choice for hygienic processes and utility applications, such as simple pasteurization, raw milk cooling, media heating/cooling, and CIP heating. For more demanding hygienic applications the Alfa Laval FrontLine Series is the preferred selection.
WORKING PRINCIPLE
The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of two fluids between which heat transfer will take place. The plate pack is assembled between a frame plate and a pressure plate and compressed by tightening bolts. The plates are fitted with a gasket that seals the channel and directs the fluids into alternate channels. The number of plates are determined by the flow rate, physical properties of the fluids, pressure drop, and temperature program. The plate corrugations promote fluid turbulence and support the plates against differential pressure.
FRAME DESIGN
The plates and the pressure plate are suspended from an upper carrying bar and positioned with a lower guiding bar, both of which are fixed to the support column. On the largest type, some tightening bolts are equipped with ball bearing washers in order to facilitate opening and closing of the unit. The frame is designed for mounting on a floor only. Standard feet are fixed. One unit can contain several heat exchangers, separated by connection plates with interchangeable connections. (Not valid for Base-3 model.)
PLATE DESIGN
The corrugation of the plates provides a passage between the plates, supports each plate against the adjacent one and enhances the turbulence, resulting in efficient heat transfer. Corner ports and gaskets are arranged so that the two media flow through alternate channels. BaseLine is available in two different plate types: Chevron and Gemini.
The chevron pattern allows for maximum strength at high working pressures. Different chevron designs are available, in order to obtain optimal high heat transfer and low pressure drop. A unique distribution area provides an even flow over the plate surface. The plates are reversible and have parallel flow, which means only one type of plate is needed.
The Gemini double wall consists of two plates pressed together. This prevents cross contamination between fluids in case of leakage through the plates. The Alfa Laval hanging system enables easy handling of the plates in the frame and together with the corner guiding a strong plate pack.

WORKING PRINCIPLE
Channels are formed between the plates, and the corner ports are arranged so that the two media flow through alternate channels. The heat is transferred through the plate between the channels, and complete counter-current flow is created for highest possible efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one, and enhances the turbulence to bring you efficient heat transfer.
STANDARD DESIGN
The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of the two fluids between which heat transfer will take place.
The plate pack is assembled between a fixed-frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket that seals the interplate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program.
The plate corrugations promote fluid turbulence and support the plates against differential pressure. The plate and the pressure plate are fixed between the upper bar and lower bar, both of which are fixed to a support column.
Connections are located in the frame plate or, if either or both fluids make more than a single pass within the unit, in the frame and pressure plates.

The tightening bolts are equipped with ball bearing washers in order to facilitate opening and closing of the unit. The frame and support column have adjustable feet. One unit may contain several heat exchangers, separated by connection plates with interchangeable connections.
Front Plate
The front plates are designed to meet the highest requirements in food processing. The combination of high pressing depth and a pattern with relatively few contact points provides longer operation time without interruptions. The distribution pattern assures an even flow over the entire plate. The port diameters enable cleaning in place (CIP) with the same flow used in the process itself.
Plate Pack
The chevron corrugation of the plates provides a passage between the plates, and supports each plate against the adjacent one. It also enhances the turbulence, resulting in efficient heat transfer. Different chevron angles are available to reach the optimal high heat transfer at a given pressure drop. A unique distribution area provides an efficient flow over the plate surface. The Alfa Laval hanging system enables easy handling of the plates in the frame. In addition, the corner guiding provides for a strong plate pack. The plates are reversible and have parallel flow, which means that only one type of gasket is needed.
Alfa Laval AlfaCond

Highly efficient and very compact
Highly efficient and very compact, AlfaCond is the world’s first plate condenser specifically designed for condensing under vacuum. Due to its compact size and efficient design, AlfaCond has become the preferred alternative to bulky indirect shell-and-tube condensers. Also, AlfaCond is easy to clean by means of Cleaning-in-Place (CIP) or mechanically.
AlfaCond is an alternative to direct condensers when condensate recovery is the goal and when there are space constraints. The AlfaCond can be configured with or without subcooling of the condensate. Non-condensables are removed from the condensate outlet pipe and led to the vacuum system.
Equipped with well-designed features, AlfaCond heat exchangers are easy to maintain and have a long service life. AlfaCond features the glued gasket, which is a two-component, oven-cured epoxy glue keeps the gasket in place during any possible cleaning condition. Additionally, the pressure plate roller, the bearing boxes on tightening bolts, and the Five-point alignment system with reinforced hangers make opening and closing the heat exchanger quick, and easy without the need for heavy tools or the risk of damaging the plates.

The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. The sealing between the plates on the AlfaCond alternates between laser welds and gaskets. It has a unique porthole configuration that is specifically designed for vacuum condensation. Vapour condenses in the welded channel and the cooling water passes through the gasketed channel.
The channel gap size is asymmetric with a larger gap on the vapour side and a smaller gap on the cooling water side. The result is a very low pressure drop on the vapour side and high velocity and turbulence on the cooling water side. Together, these maximize heat transfer efficiency and minimize fouling.
Alfa Laval WideGap
Alfa Laval WideGap gasketed plate-and-frame heat exchangers are suitable for fibrous fluids and for fluids containing coarse particles. Typical applications for Alfa Laval WideGap heat exchangers are sugar, bioethanol and pulp and paper processes. Depending on the duty, the WideGap heat exchangers that ABS offers can be configured either with wide-wide or wide-narrow channels. This makes the units suitable for heating, cooling and interchanging duties.

Unique design for thermal efficiency
Alfa Laval’s AlfaVap unique design provides higher thermal efficiency than the traditional shell-and-tube evaporators and because of this much less heat transfer area is needed. AlfaVap heat exchangers are cost-efficient especially when exotic metal materials are required.
AlfaVap’s advantage is that they work also when the temperature differential between the hot and cold fluids approaches as low as 2.5°C (4.5°F) meaning that lower grade steam and more effects in series can be use in an evaporation system compared to the shell-and-tube systems. This saves steam costs.
Compact design and versatility
The compact design and versatility of the AlfaVap means that they are cost-efficient and easily installed even at high elevations.
AlfaVap heat exchangers are easily accessible for inspection and mechanical cleaning by removing the tightening bolts and rolling back the pressure plate. For Cleaning-in-Place (CIP), only a small amount of cleaning chemicals is needed because of their low hold-up volume.
AlfaVap’s design makes it easy to adjust evaporation capacity to meet changing needs by adding or removing plates to the existing frame. This is a major advantage over shell-and-tube units where the capacity cannot be changed once it’s installed.
Equipped with well-designed features, the AlfaVap heat exchangers are easy to maintain and have a long service life. They feature a clip-on gasket which is a glue free gasket that ensures perfect sealing and trouble-free maintenance. Additionally, the pressure plate roller, the bearing boxes on tightening bolts, and the Five-point alignment system with reinforced hangers make opening and closing the heat exchanger quick and easy without the need for heavy tools or the risk of damaging the plates.

The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. The sealing between the plates on the AlfaVap alternates between laser welds and gaskets. Alfa Laval AlfaVap is tailor-made for evaporation. It has two inlet feed connections located centrally at the bottom of the frame plate and a large outlet for the vapour and concentrate at the top. The heating steam condenses in the welded channels and the evaporating product passes through the gasketed channels.
Industrial semi-welded line
Alfa Laval Industrial semi-welded line is used when gaskets are not suitable for one of the process media. Also, the semi-welded line can take a higher design pressure compared to fully gasketed plate-and-frame heat exchangers.

Unique sealing system
Alfa Laval Industrial semi-welded line handles most refrigerants and is particularly suitable for applications involving ammonia. Semi-welded heat exchangers are used in both organic and inorganic chemical processing when the chemicals involved limit the selection of gaskets that can be used or when the required design pressure makes fully gasketed plate-and-frame heat exchangers insufficient.
The media passes through the welded channel facing the ring gasket sealing between the laser welded cassettes. Alfa Laval semi-welded heat exchangers employ the Alfa Laval RefTight™, a unique sealing system which guarantees high performance by positioning the laser weld on the outside of the ring gasket groove. The smooth ring gasket grove ensures equal sealing force over the entire porthole gasket.
Equipped with well-designed features, Alfa Laval Industrial semi-welded line of heat exchangers are easy to maintain and have a long service life. Some of the features available include:
- ClipGrip™ gasket – a glue free gasket with superior alignment that ensures a perfect seal and trouble-free maintenance.
- Alfa Laval RefTight™ – a unique gasket groove design with maximum gasket support and minimum gasket contact.
- CurveFlow™ distribution area – ensures full use of the heat transfer area and minimizes fouling.

The heat transfer area of a gasketed plate-and-frame heat exchanger consists of a series of corrugated plates, assembled between the frame and pressure plates, which retain the design pressure. For the highest thermal performance and to enable a very close temperature approach, fluids normally run counter-currently through the heat exchanger.
The sealing between the plates on the Industrial semi-welded line alternates between laser welds and gaskets. The laser welded channel allows use of fluids that are not compatible with normal gaskets and also allows for higher design pressure than fully gasketed plate-and-frame heat exchangers. Additionally, the Alfa Laval RefTight™ sealing system guarantees equal sealing force over the entire porthole gasket.
Industrial semi-welded line is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are carefully designed and selected to achieve optimal performance. The CurveFlow™ and the chocolate pattern distribution area are two design features available that ensure fluids are evenly distributed across the entire plate. The result is that the entire heat transfer surface is fully utilized and stagnant zones that can result in fouling are avoided.
High flow turbulence between plates results in higher heat transfer; however, the consequence is pressure drop. Our thermal design engineers will help you design and select the model and configuration that is suitable for your application needs while delivering maximum thermal performance and minimizing pressure drop.
The Industrial semi-welded line can be configured in many ways. The animation shows single pass configuration of a fully gasketed plate-and-frame heat exchanger. The flow principle of a semi-welded heat exchanger is the same. The difference is that every second channel is sealed with a laser weld instead of a gasket. Multi pass with 2 or more passes on each side is also possible.
Alfa Laval Diabon Heat Exchanger
ABS offers the Alfa Laval Diabon® plate-and-frame heat exchangers that are used for tough corrosive media. This range of heat exchangers combine Alfa Laval’s know-how in heat transfer with Germany based SGL Carbon’s expertise in graphite process equipment. Alfa Laval Diabon® gasketed plate-and-frame heat exchanger combines high-efficiency heat transfer benefits with the exceptional corrosion resistance of graphite material.
Alfa Laval and SGL Carbon, Germany, worked together to develop DIABON® plate heat exchangers. This collaborative effort combines Alfa Laval’s plate heat exchanger know-how with SGL Carbon’s expertise in graphite process equipment. The resulting product combines the high-efficiency heat transfer benefits of conventional plate heat exchangers with the exceptional corrosion resistance of graphite material.
DIABON® plate heat exchangers are therefore ideal for handling highly corrosive fluids such as:
- hydrochloric acid and gas in all concentrations
- sulphuric acid up to 90%
- hydrofluoric acid up to 60%
- all concentrations of phosphoric acid
- pickling acids in surface treatment plants
- electrolytes used in the mining industry
- mixed acids
- chlorinated hydrocarbons
- catalysts such as aluminium chloride.
Alfa Laval DIABON® plate heat exchangers work on the same principle as conventional plate heat exchangers, except that the plates separating the media are made of special graphite materials.
The graphite plates are available in three different material grades, DIABON® F100, NS1 or NS2. The channels formed when these graphite plates are assembled in a plate pack are sealed by PTFE gaskets.
In addition, the tightening bolts on the frame are fitted with springs to compensate for thermal expansion of the plate pack, hence minimizing the risk of cracking the plates.
PTFE rope gasket
Alfa Laval DIABON® plate heat exchangers are all supplied with a PTFE rope gasket. When the heat exchanger is assembled, this gasket rope is flattened to a very thin film approx. 0.2 mm).
The thinness of the gasket means that the area in contact with the chemical is very limited, resulting in an extremely long service life. To date, the gasket has proved resistant to attack by all known chemicals, as well as resisting very high temperatures (>180°C).
In addition, the gasket can be kept in storage for virtually unlimited periods.
Applications
Heaters, coolers, interchangers, condensers and evaporators
for corrosive media, especially in the treatment of:
-Hydrochloric acid (HCl)
-Sulfuric acid (H2SO4)
-Hydrofluoric acid (HF)
-Mixed Acids (HNO3/HF)
-Phosphoric acid (H3PO4/P2O5)
-Other organic and inorganic media
Standard design
The graphite plate heat exchanger consists of a pack of
corrugated graphite plates with portholes for the passage of
the two fluids between which heat transfer will take place.
The plate pack is assembled between a carbon steel fixed
frame plate and movable pressure plate and compressed by
tightening bolts. The difference in coefficients of expansion of
carbon steel and graphite is compensated for by means of
helical springs.
The plates are fitted with a film type PTFE gasket of 0,2 mm
thickness after tightening, which seals the interplate channel
and directs the fluids into alternate channels. The number
of plates is determined by the flow rate, pressure drop and
temperature program. The plate corrugations promote fluid
turbulence and minimize fouling.
The frame plate and pressure plates are suspended from an
upper carrying bar and located by a lower guiding bar, both of
which are fixed to a support column. Connections are located
in the frame plate or, if either or both fluids make more than a
single pass within the unit, in the frame and pressure plates.
The frame and pressure plates are protected from the
corrosive media by means of a PTFE lining.
Typical capacities
Max flow rate of 250 m3
/h, depending on media, permitted
pressure drop and temperature program.
Plate types: S1, M10-G, S10, S15.
Frame types: One standard frame available that can be
modified to higher design pressures.
Working principle
Channels are formed between the plates and the corner ports
are arranged so that the two media flow through alternate
channels. The heat is transferred through the plate between
the channels, and complete counter current flow is created for
the highest possible efficiency. The corrugation of the plates
provides the passage between the plates, supports each
plate against the adjacent one and enhances the turbulence,
resulting in efficient heat transfer.
Standard materials
Plates: F100, NS1/NS2
