Introducing the new Alfa Laval AC540 family of brazed plate heat exchangers – four new high-efficiency models, designed to work with the low-GWP refrigerant of your choice
Alfa Laval launched the new Alfa Laval AC540 brazed plate heat exchanger at their first online net-zero launch event, where they showcased new, cutting-edge thinking in energy-efficiency, clean energy, and circular-economy solutions. To address the many changes that are reshaping the rapidly-evolving world of refrigerants, Alfa Laval developed the Alfa Laval AC540 family of brazed plate heat exchangers, with designs that are specifically optimized to work with R32, carbon dioxide, and other low-GWP refrigerants.
Environmental concerns and legislation aimed at addressing climate change are challenging the HVAC industry to increase its focus on enhanced performance and improved energy efficiency and to rethink its choice of refrigerants.
Increasing the use of low-GWP refrigerants, including natural refrigerants such as propane and HFCs such as R32, is one key aspect of addressing climate impact. Another important aspect is reducing the energy required per unit of cooling. The AC540 family is targeted to do both, in a kW range designed to meet the requirements of system builders.
CO2 is also gaining prominence in the market, having become the norm in commercial refrigeration applications, such as in supermarkets, and also has benefits in other applications, including large-capacity chillers and large heat pumps.
The Alfa Laval AC540 family of brazed plate heat exchangers was designed to meet these challenges
In terms of size, capacity and place within our offering, the AC540 family falls between the AC502 and the AC1000 and is ideal for use with multiple scroll chillers from 250-800kW. It is 750 mm high and 400 mm wide and works with a wide range of high-density, low-GWP refrigerants.
The AC540 family incorporates unique, cutting-edge features, including DynaStaticTM distribution, which can be optimized for a specific application and refrigerant, and IceSafe, which helps our customers manage freezing. The 540 family also features FlexFlowTM and PressureSecure, which enables reliable operation even at very high pressures.
“Alfa Laval invests heavily in product development, and our focus on innovation is really apparent in this new family of brazed heat exchangers. The unique asymmetric plate design of this family makes it possible to minimize the evaporator’s refrigerant charge and also reduces the pressure drop on the secondary side, making it possible to use a smaller pump, which lowers electricity consumption and reduces overall costs,” says Fredrik Ekström, President, Business Unit Brazed & Fusion Bonded Heat Exchangers.
The 540 family includes four models, all of which are manufactured at Alfa Laval’s new, state-of the-art factory in San Bonifacio, Italy.
- The ACK540 is a high-capacity unit that offers exceptional thermal performance making it ideal for evaporation duties in HVAC applications.
- The ACH540 is similar in design to the ACK540, but with a design pressure of 48 bar, it is more suitable for use with other high density refrigerants.
- The CBP540 can be used as a flooded CO2 evaporator, making it possible to extend the benefits of plate technology to duties that were traditionally limited to shell & tube heat exchangers.
- The ACP540 is optimised for CO2. It functions as a DX evaporator for use in subcritical cascade systems.
The 540 family is a great addition to Alfa Laval’s comprehensive portfolio of efficient, innovative and sustainable solutions. And of course, just like all of our products, they are supported by a worldwide network of experts who truly understand our customers’ business needs.”
