Product Information – Alfa Laval Gasketed plate-and-frame heat exchangers
Our gasketed plate heat exchangers are optimizing heat transfer by large surfaces of corrugated plates drawing heat from one gas or liquid to the other. The high efficiency and an outstanding reliability in a compact design, offers an investment with the most attractive CTO over the product lifetime. Not to forget the energy saving capabilities and low environmental footprint.
Gasketed plate heat exchangers for modern requirements
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 can 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.
Our wide range of gasketed plate heat exchangers are suitable for all types of industry and multiple applications from heating, cooling and heat recovery. We are constantly looking to extend and upgrade the range, adding new performance criteria and greater flexibility. What’s termed ‘next-generation’ today will soon be standard for the entire Alfa Laval Industrial line.
