Gasketed plate-and-frame heat exchangers

Gasketed plate-and-frame heat exchangers provide efficient heat transfer in compact equipment with a small footprint. The units have a flexible design and are easy to service and maintain. The product range is extremely wide and is used in duties for heating, cooling, heat recovery, evaporation, and condensation in industries ranging from HVAC, refrigeration, engine cooling, dairy, and food to heavier processes like chemical processing, oil production, and power generation.


Industrial line

Alfa Laval Industrial line is an extremely wide product range that is used in all types of industries. The number of sizes, plate and gasket materials, and available options are enormous.

Industrial semi-welded line

Alfa Laval Industrial semi-welded line is used when gaskets are not suitable for one of the process media.



ClipGrip™ gaskets offer superior fastening to the plate. Not only do the next-generation gaskets stay in place better than before, but they are also easier to mount in the first place. The unique design prevents the snaking of plates at closing and the tangling of new gasket sets. Maintenance of the heat exchanger goes faster, plates and gaskets last longer, and you save money as a result.

Compact frame

The Compact frame feature offers more capacity in a smaller footprint. The smart guiding bar enables a maximum number of plates or cassettes in the frame while keeping the service area requirements down to a minimum. The design enables a faster and safer service which minimizes downtime and reduces maintenance costs.

T-bar roller

In the next-generation plate heat exchanger, Alfa Laval has replaced the traditional roller function built on top of the carrying bar with a T-bar roller. The pressure plate roller is mounted under the carrying bar, decreasing the height of the heat exchanger and making maintenance simpler and more cost-effective. This design also protects the roller from falling dust and debris, which prevents jamming, minimizes the potential for damage to the frame, and ensures easy opening and closing of the unit when required.

Bearing boxes

Alfa Laval’s large and medium model gasketed plate heat exchangers employ tightening bolts with bearing boxes to reduce friction when opening and retightening the unit. This makes it possible for one person to easily and safely service the heat exchanger without the need for special tools. The bearing box thus offers significant advantages over competing solutions designed with a simple nut and washer, where maintenance is laborious, time-consuming, and potentially hazardous.


The FlexFlow™ plate design improves thermal efficiency and optimizes pressure drop utilization. The asymmetric channels eliminate the compromise between thermal efficiency and pressure drop for duties with different hydraulic loads on the two sides of the heat exchanger. The result is up to 30% higher efficiency along with reduced fouling, for long-term, cost-effective performance.


The CurveFlow™ distribution area optimizes the flow of media for better utilization of the whole plate surface. Improving the flow with a more even distribution eliminates dead spots, providing higher thermal efficiency with a reduced risk of fouling. This in turn means energy savings, lower maintenance costs, and less time worrying about unplanned stops.


The OmegaPort™ noncircular inlet and outlet offer two ways to save on energy: both higher thermal efficiency and reduced pump costs. That’s because it enhances the flow of media to give increased throughput, lower pressure drop, and optimal utilization of the plate surface.

Offset gasket groove

The next generation of gasketed plate heat exchangers is designed with a gasket groove in a special zig-zag pattern that offers the greatest possible heat transfer area. Better utilization of the whole plate reduces the number of plates required for optimal performance and ensures maximum thermal efficiency for still greater energy savings.

Welded plate-and-block heat exchangers

The Alfa Laval Compabloc range provides compact and efficient heat transfer for a wide range of clean and dirty process duties. Full and easy cleanability on both circuits makes it the most service-friendly welded heat exchanger on the market.


Type 1

Customized solution that ensures maximum heat recovery with counter-current flow. Used for liquid-liquid fouling duties.

Type 2

A customized solution that ensures cross-flow condensing with the lowest possible pressure drop. Used for 2-phase duties, both condensing and evaporation (reboiling).



Alfa Laval ClipLine range is used in the same hygienic applications as the FontLine range, but ClipLine is used for smaller duties.


Alfa Laval BaseLine is a range of heat exchangers used in dairy, food, beverage, and other hygienic applications.

M line

Alfa Laval M line range is used in the same hygienic applications as the BaseLine range, but M line is selected when higher design pressure or when extra-long plate packs are required.


Alfa Laval FronLine is the premium range used in dairy, food, beverage, and other hygienic applications requiring gentle product treatment, long operating time, or superior cleanability.
