The Air Conditioning, Heating and Refrigeration Institute (AHRI) Standard 400 certification is an independent, third-party verification of thermal performance. Through its certification program and standards, AHRI strives to help customers save energy, improve their productivity and help to ensure a better environment.
AHRI Certified™ is the trusted mark of performance assurance for heating, ventilation, air conditioning and commercial refrigeration equipment. Products earning the mark undergo rigorous, independent annual evaluation to ensure that they perform according to the manufacturers’ published claims. Certifying HVACR equipment and component performance allows consumers to compare products based on independently verified performance ratings. To find AHRI Certified™ products, go to the AHRI directory.
AHRI Certification Procedures and Benefits
To certify a product to AHRI standards, the manufacturer submits specifications and performance data to AHRI for performance evaluation and potential certification.
Once certified, buyers and users can be assured that:
- The plate heat exchanger will perform in accordance with the manufacturer’s published ratings.
- Product performance can be easily compared for their specific application.
The CBAQ range of brazed plate heat exchangers has numerous advantages over traditional heat exchangers HVAC installations. The exceptional heat transfer efficiency makes all CBAQ units very compact. As a result, they can tackle large-capacity duties even though there is only limited installation space available.
The brazed construction also does away with gaskets, making CBAQ units ideal in applications where temperatures and/or pressures are high. Examples include district heating and a wide range of heating, cooling and tap water solutions.
Units in the CBAQ range are available in many different sizes and capacities.
Cost effective for everyone involved
- Reduces lifetime operating costs significantly by assuring a more energy-efficient system
- Ensures full investment value by reducing costs for field tests and additional component performance margins
- Allows for the design of a system in which all the major components are independently performance certified
- Ensures that targets on power consumption and climate control can be met
- Provides a verifiable basis for heat exchanger selection
- Protects the owner and consulting engineer from performance concerns during commissioning and after installation
- Ensures that all certified plate heat exchangers included in proposals will deliver the stated thermal performance
- Reduces troubleshooting time during commissioning and after start-up
How it works
Heat transfer technology involves bringing two substances at different temperatures close to each other so that one either heats or cools the other.
A brazed plate heat exchanger consists of thin, corrugated stainless steel plates, stacked into a plate package and brazed together with pure copper.
The brazing material seals and holds the plates together at the contact points ensuring optimal heat transfer efficiency and pressure resistance. The plate design guarantees the longest possible life. Brazing the stainless steel plates together eliminates the need for gaskets and thick frame plates.
Pressure peaks and rapid temperature cause substantial physical stresses within the materials, and Alfa Laval’s research has focused on the details of these phenomena in order to ensure designs that are extremely resilient and provide a long service life.
