SPARTA, Wis. - Multistack®, maker of modular chillers, received Air-Conditioning, Heating and Refrigeration Institute (AHRI) Certification on all production model water-cooled chillers for both the United States and Canada. According to the company, this measure supports the fact that Multistack modular chillers are more than just a unit that fits through a standard doorframe.

“Multistack has worked hard for more than 20 years to provide product performance data with accuracy and integrity” said Mark Platt, president of Multistack. “AHRI Certification was the next logical step in this pursuit. At Multistack we take our responsibility as an industry leader seriously, and achieving AHRI Certification on all of our water-cooled modular chillers is just one more example of this.”

As stated on the AHRI website, “The AHRI Certified™ mark is applied only to HVACR equipment and components that have been independently tested to certify manufacturers’ performance claims are accurate.” AHRI defines a rigorous procedure for qualifying manufacturer test facilities and product witness testing to satisfy the requirements of this program. The modular chillers produced by Multistack encompass scroll, screw, and centrifugal compressor technology using refrigerants R-22, R-407C, R-410A, and R134a.
