Alfa Laval introduces AC900, next-generation heat exchanger for low-density refrigerants
The AC900 is a single-circuit heat exchanger optimized for full and partial-load conditions, suitable for 300-600 kW capacities in chillers, screw compressors, industrial chillers, and heat pump applications.
An efficient alternative to shell-and-tube heat exchangers
Because the AC900 can manage larger than average capacities, it creates new possibilities in applications where shell-and-tube heat exchangers currently dominate. With its extra-large gas outlet port and DynaStatic distributor system, the AC900 is capable of covering capacities up to 600 kW, and can be custom configured to deliver maximum performance, from partial to full load, in a range of applications.
Saving money and resources
The AC900 is also a great solution for small-to-medium capacity chillers with screw compressors, and for heat pumps and industrial chillers. It requires a much lower refrigerant charge and is more compact, which makes it less expensive to install and also helps save vital steel and copper resources. The lower installation cost is one part. It is also positive from environmental point of view: the less refrigerant the better.
World-class performance
Recently, the AC900 was tested as a condenser and evaporator at a heat pump manufacturer using a low density refrigerant. The AC900 performed far better than the competition, reaching a new level of thermal performance. “The numbers were quite impressive, and the customer considers the AC900 the absolute best-in-class in this application,” says Roman Rathsack, Senior Global Business Development Manager, Business Unit Brazed & Fusion Bonded Heat Exchangers.
Designed with the environment in mind
Alfa Laval is dedicated to accelerating sustainable solutions in the energy market. With that in mind, the AC900 was designed according to the performance specifications of SEER (Seasonal Energy Efficiency Ratio), defined by the Air Conditioning, Heating and Refrigeration Institute. It also complies with strict new ECO-design requirements defined by The European Environment Agency.
Unique features
- The Alfa Laval AC900 incorporates several unique features.
- DynaStatic distribution, Alfa Laval’s most recent distribution system, is highly flexible, making it easy to change the geometry inside the distributor. This makes the AC900 adaptable to future trends and future customer needs, including changes in application requirements, new refrigerants, or any other requests.
- IceSafe helps customers prevent and manage freezing in applications with low temperatures.
- ReFuture ensures that the AC900 was designed for optimal performance not only with today’s refrigerants, but with tomorrow’s, making it a future-proof investment that allows customers proactively to address sustainability goals and legislative requirements.
