AHRI Launches Variable Frequency Drives, Datacom Cooling Certification Programs

ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute announced two new certification programs for variable frequency drives and datacom cooling equipment.

“AHRI manages 40 performance certification programs for HVACR and water heating products,” said AHRI Vice President of Certification Bill Tritsis. “We are excited to introduce these new programs to meet increasing demand for independent performance verification for these products.”

VFDs produce fast-rising, high-frequency pulses of electrical energy to control and power motors. The equipment in the Variable Frequency Drives Certification Program is rated and tested in accordance with ANSI/AHRI Standard 1210, Performance Rating of Variable Frequency Drives. Once considered a “high tech” option for only the most elaborate HVACR systems, VFDs have been in the mainstream for several years, providing better efficiency with improved reliability.

Datacom cooling equipment is used to remove the immense heat generated in computer rooms and data centers, and support consistent information sharing and processing around the world. Equipment in the program will be rated in accordance with AHRI Standard 1360, Performance Rating of Computer and Data Processing Room Air Conditioners. AHRI is currently soliciting quotes for laboratory testing and expects to launch the program in January 2014.
