Alfa Laval AC brazed plate heat exchangers provide efficient heat transfer with a small footprint. They are specifically designed to work in air conditioning and refrigeration applications as evaporators and condensers in chillers and heat pumps.
- Cascade systems
- Easy to install
- Low level of service and maintenance is required
- All units are pressure and leak tested
- Gasket free
The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. Using advanced design technologies and extensive verification guarantees the highest performance and longest possible service life.
Different pressure ratings are available for different needs. Asymmetric channels provide optimal efficiency in the most compact design. This results in low refrigerant charge or lower pressure drop on the water or brine side, reducing the CO2 footprint.
Based on standard components and a modular concept, each unit is custom-built to meet the specific requirements of each individual installation. Suitable with most HFC, HFO and natural refrigerants.
