Alfa Laval AC Brazed PHE AC502DQ / ACH502DQ

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.

Applications

  • EvaporatorALFA LAVAL, AC HEAT EXCHANGER, AC502DQ-ACH502DQ
  • Condenser

Benefits

  • Compact
  • Easy to install
  • Self-cleaning
  • Low level of service and maintenance is required
  • All units are pressure and leak tested
  • Gasket free

Design

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.

The True dual-circuit design provides a higher freezing resistance compared to back-to-back solutions. 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. The asymmetry guarantees the best performance in both fulland partial-load conditions. 

Designed for high-efficiency applications, such as those applications with high evaporation temperature and low water/brine pressure drop. This results in reduced environmental impact and lower costs. The integrated distribution system ensures an even distribution of the refrigerant throughout the plate package. 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.
