AHRI Launches Product Section for Fluid Pumps; Publishes Standard for Walk-in Units

The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) has announced the launch of a fluid pump product section, and the publication of a standard for walk-in coolers and Freezers.

The fluid pump product section was unanimously approved by AHRI’s Board of Directors at its November 15, 2009 meeting. It’s now compiled with AHRI’s 40 additional product sections.

The section covers all roto-dynamic centrifugal pumps and circulators used for circulation of fluids in residential and commercial buildings primarily used in the following applications:

• closed-loop heating and cooling systems (primary, secondary, zone, and loop pumps)
• domestic hot water recirculation
• pressure boosters
• steam systems
• cooling towers

AHRI Standard 1250-2009 —”Performance Rating of Walk-In Coolers and Freezers” — is available for free download at ahrinet.org. The standard establishes definitions, test requirements, rating requirements, minimum data requirements for published ratings, operating requirements, marking and nameplate data, and conformance conditions for walk-in coolers and freezers.
