Alfa Laval Industrial line is an extremely wide range of gasketed plate-and-frame heat exchangers used in all types of industries. The number of sizes, plate and gasket materials and available options are enormous. Every detail is carefully designed to ensure optimal performance, maximum uptime, and easy maintenance.
The Industrial line’s versatility allows it to be designed and configured for applications ranging from relatively simple duties with low requirements to very demanding duties with the highest requirements on both performance and documentation. The products are used for heating, cooling, heat recovery, condensation, and evaporation.
Equipped with well-designed features, the Industrial 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.
- Glued gasket – a two-component, oven-cured epoxy glue keeps the gasket in place during any possible cleaning condition.
- CurveFlow™ distribution area – ensures full use of the heat transfer area and minimizes fouling.
Additionally, the pressure plate roller, the bearing boxes on the tightening bolts, and the 5 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.
Alfa Laval Industrial line is quick and easy to modify if process parameters change. Our team’s expertise and the availability of parts bring you peace of mind.
Plate types for different needs
Industrial line is available with four different plate configurations:
- Single plate with a chevron pattern design for parallel flow allows for optimum thermal performance and pressure drop.
- Single plate with a chevron pattern design for diagonal flow allows for optimum thermal performance through the heat exchanger when it is mounted horizontally and requires complete drainability.
- Double wall plate is used when extra care is needed to avoid mixing fluids.
- Gemini double wall plate is used when extra care is needed to avoid mixing fluids in hygienic applications.
- High energy efficiency
- Flexible configuration
- Easy to install
- High serviceability
- Access to Alfa Laval’s global service network
How it works
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.
The Industrial line is available with various pressing depths and angles of the chevron pattern and various shapes of the corrugation which are all 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.

Product in focus: Alfa Laval T8
The new Alfa Laval T8 gasketed plate heat exchanger is designed to meet the highest expectations when it comes to energy efficiency, compactness and reliable performance. With its innovative design and simplicity it brings you the best of Alfa Laval’s 80 years of knowledge in gasketed plate heat exchangers.
Benefits and values
High energy efficiency
With its new innovative plate design, the Alfa Laval T8 provides superior flow distribution across the entire plate surface. Compared to a traditional plate design, the T8 also maintains a low-pressure drop in the distribution area while enabling high-pressure drop for heat transfer. This results in improved heat transfer and higher energy efficiency thanks to the elimination of stagnant zones and reduced risk of fouling.
The compact design of the Alfa Laval T8, less than 1m in height, makes it easy to fit compact spaces. It comes equipped with all features needed for easy installation and quick start-up.
Reliable performance over time
Depending on fluid types, pressures and temperatures, the Alfa Laval T8 is tailored to meet highest expectations on performance and lifetime. Alfa Laval T8 is also available as an AHRI performance certified version called Alfa Laval AQ3. The performance certification is according to AHRI Standard 400 and is verified in the AHRI Liquid to Liquid Heat Exchanger certification program, LLHE.
Easy and safe maintenance
A new gasket and plate pack alignment design provides easy and cost effective maintenance. The frame is equipped with features that support the unit and secure safe opening and closing during service.
Alfa Laval CurveFlow™ distribution area
The new design of the distribution area in T8 means superior flow distribution and more of the available pressure drop over the main heat transfer area. This results in a number of benefits:
- A more compact heat exchanger – less plates needed.
- Increased energy efficiency – better flow distribution reduces the risk of fouling build up, reducing the need for increased pumping power to compensate for higher pressure drop.
- Reduced maintenance costs – fewer plates mean faster cleaning and low cost for spares.
Alfa Laval ClipGrip™ gaskets
Glue-free gaskets for fast and completely glue-free mounting thanks to new Alfa Laval ClipGrip™. Based on the innovative fastening design, gaskets stay in place during maintenance while reducing consumption of spare parts and additional time for re-gasketing.
Perpendicular corner guiding
The new corner guiding design ensures that the plate pack is perfectly aligned independent of the number of plates. A perfect alignment ensures a reliable performance of the heat exchanger and faster closing of the unit after service.
