The selection of a plate heat exchanger should always be based on reliable data. In practice, however, there are cases where manufacturers or suppliers underestimate heat transfer calculations in order to propose a lower-cost solution. Such under-dimensioning results in:
- higher energy consumption,
- increased operating costs,
- reduced efficiency of the entire system.
For designers and end users, this means uncertainty regarding the actual performance of the system.
AHRI certification – objective verification
To eliminate the risk of discrepancies between catalog data and actual performance, the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has developed a certification program for liquid-to-liquid heat exchangers.
It is the only independent system in the world that confirms a unit operates in accordance with the manufacturer’s published ratings. Certification is based on regular, objective testing performed in AHRI-approved laboratories.
JAG heat exchangers and performance assurance
Hexonic JAG plate heat exchangers are AHRI certified. This means their thermal performance has been verified by an independent institution, and the values stated in the documentation fully reflect real operating conditions.
For both end users and system designers, this ensures:
- accurate matching of the heat exchanger to the application,
- no need to apply additional safety margins,
- reduced risk of over- or under-sizing,
- lower operating costs throughout the system’s lifecycle.
