The Air Conditioning, Heating, and Refrigeration Institute (AHRI), formed in 2008 by the merger of the Air-Conditioning and Refrigeration Institute (ARI) and the Gas Appliance Manufacturers Association (GAMA), is a North American trade association of manufacturers of air conditioning, heating, and commercial refrigeration equipment. The organization performs political advocacy on behalf of its member industries, maintains technical standards, certifies products, shares data, conducts research, and awards scholarships.

In light of the above, it is apparent why AHRI is worthwhile both for consumers (who can finally be sure of the quality of the products they have chosen), and also manufacturers (as AHRI represents an opportunity to offer highly efficient solutions and manufacturers could receive recognition at international level)

"IES" Liquid-to-Liquid Heat Exchanger is certified by AHRI as an Original Equipment Manufacturer (OEM) since January 2017. The purpose of AHRI mainly applies to products which use air-conditioning or heating system to ensure the same benchmark and evaluation within the same level of standard. The AHRI Certification Programs are accredited by the Standards Council of Canada to ISO/IEC Standard 17065 as a Type 4 certification system. In order to simplify trading of tested products around the world without the need for further tests, AHRI has reached reciprocal recognition agreements with certification bodies and provide manufacturers with the assurance that the equipment will perform accurately and consistently. Many famous large-scale heat exchanger brands in the world are AHRI members, obeying the unified standard of efficiency and enhancing the integrity of the enterprise. AHRI will review the product's performance regularly in order to justify the prescribed AHRI Standard rating methodology and claim the equipment has been "rated in accordance" with the standard. 


ISO 3834:2006

The welding process is a unique and highly technical process.  In order to ensure the quality of the weld,   ISO 3834 is based on ISO/TC44 and is set up for every aspect of the welding process. Similar to ISO9000, ISO3834 is not a mandatory certification, but if a manufacturing enterprise is strictly controlled by ISO 3834, its product quality can be guaranteed.
