Design
Equipped with well-designed features the 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 that keeps the gasket in place during any possible cleaning condition.
- CurveFlow™ Distribution Area – ensures full use of heat transfer area and minimizes fouling.
Additionally, the pressure plate roller, the bearing boxes on 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.
AlfaQ is quick and easy to modify if process parameters change. With expertise and availability of parts, the team ensures clients of high quality service.
Plate types for different needs
AlfaQ™ is available with two different configurations;
- Single plate with a chevron pattern design for parallel flow allowing for optimum thermal performance and pressure drop.
- Single plate with a chevron pattern design for diagonal flow through the heat exchanger when its mounted horizontally and requires draining.
Benefits
- High energy efficiency – low operating cost
- Flexible configuration – heat transfer area can be modified
- Easy to install – compact design
- High serviceability – easy to open for inspection and cleaning and easy to clean by CIP
- Access to Alfa Laval’s global service network,

AHRI Performance Certification
The Air Conditioning, Heating and Refrigerant Institute (AHRI) certification is an independent, third-party verification of thermal performance. Through the certification program and standards, AHRI strives to ensure energy saving, improve productivity, and help to ensure a better environment.
AHRI Liquid to Liquid Heat Exchanger (LLHE) Certification Program ensures that the product performs in accordance with manufacturers’ published specifications, and is particularly useful in applications such as district cooling substations and free cooling systems.
Products that are certified through the AHRI Product Performance Certification Programme are continuously tested, at the direction of AHRI, by an independent third-party laboratory, contracted by AHRI, to determine the products ability to conform to one or more product rating standards or specifications.
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.
AlfaQ™ 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 optimum 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.
