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 unit can be supplied with a refrigerant distribution system for optimal evaporator performance.  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.
