Alfa Laval AlfaQ™ heat exchangers are used for HVAC applications such as district cooling substations, ice-storage systems, data centers, and free cooling systems. The range is certified according to the AHRI Liquid to Liquid Heat Exchangers (LLHE) Certification Program which ensures thermal performance according to manufacturers’ published specifications. AHRI certification is the only global, third-party performance certification for plate heat exchangers.

New standards in efficiency, reliability and serviceability

Our AHRI certified plate-and-frame heat exchangers are energy efficient, compact and simple to maintain. The vast range of options when it comes to size, plate and gasket material means they can be specifically designed and configured for your needs.

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.
