Alfa Laval AC74 brazed plate heat exchangers

Alfa Laval, the innovator of heat transfer technologies, has continued a focus on more sustainable heating and cooling systems with the launch of the Alfa Laval AC74: a new generation of brazed plate heat exchangers.

Engineered as a flexible solution for air conditioning and process cooling duties, the AC74 includes unique technologies developed to improve energy efficiency and enable the use of refrigerants with low global warming potential (GWP).

While offering environmental benefits, many low-GWP refrigerants place high demands on heat exchanger technologies. Among other things, this can include low temperatures that result in freezing, which in turn damages the equipment. Some refrigerants, such as R-32 (Difluoromethane), also require high operating pressures that pose a challenge for many existing heat exchangers on the market.

By ensuring ideal distribution for the media, DynaStatic further contributes to the higher efficiency of the AC74 heat exchangers. AC74 also features a new channel plate that takes advantage of Alfa Laval’s FlexFlow™, a patented asymmetrical plate design that enables more efficient thermal transfer through optimized pressure drop and increased turbulence.

Alfa Laval has primarily designed AC74 heat exchangers for use in air conditioning and process cooling applications, but the sustainable design offers new possibilities for a wide range of duties. AC74 models also cover a higher kilowatt range than similar heat exchangers in the past, from 50 kW up to 160 kW.
