IIAR Remembers

Klaas Visser, known to the natural refrigeration industry as a relentless environmental advocate who is credited by many for helping lead the renaissance of CO2, as well as a tireless innovator who introduced pivotal new refrigeration system designs, has passed away at the age of 83.

Colors of Ammonia?

If you have been around the ammonia refrigeration industry for a while you know ammonia is clear (colorless) unless it has been contaminated with impurities. However, over the last several years ammonia is more often being referred to with a color, which is not referring to the ammonia, but the process used to manufacture it.

IIAR, RETA, GCCA, ASTI Form Coalition to Promote Natural Refrigerants

Safety, prevention, and emergency response readiness are top priorities within the natural refrigerant industry, and the Ammonia Safety Training Institute, IIAR, Global Cold Chain Alliance, and Refrigerating Engineers & Technicians Association have come together to form the Ammonia Safety Day Coalition.

Bridging the Gap: IIAR’s Newest Standard to Address Hydrocarbons in Industrial Refrigeration

IIAR is nearing the completion of its first standard for hydrocarbons—such as propane and butane—in large refrigeration systems. Hydrocarbons have been used for years in the petrochemical industry and are increasingly used in some refrigeration applications.

Natural Refrigerants Continue to Grow in Retail

Adoption of natural technologies in new and existing retail space is increasing as companies work to increase sustainability while meeting consumer, employer and shareholder expectations. “Many retailers, especially national chains, are prepared to make very large investments to significantly reduce their carbon footprint by converting to naturals in existing stores,” said Danielle Wright, executive director of the North American Sustainable Refrigeration Council.

Its’ HOT!

Sometimes it may be difficult to understand but we all have free agency to believe what we want. Some people believe the earth is flat. Some believe we never landed on the moon. I suppose there are people who believe those amazing photos from various robotic machines on Mars are fake too.

Industry Joins Together to Provide Valuable Training to OSHA Inspectors

Occupational Safety and Health Administration compliance officers are continuing to benefit from ammonia refrigeration education presented by the Industrial Refrigeration Consortium. The training, which is funded by IIAR, the Global Cold Chain Alliance, IRC, and OSHA, first launched in the fall of 2014.

IIAR Petitions EPA for Increased Hydrofluorocarbon Restrictions

The International Institute of Ammonia Refrigeration and its industry partners have petitioned the Environmental Protection Agency to use its authority under the American Innovation and Manufacturing Act to restrict the use of hydrofluorocarbons within the refrigeration sector. The AIM Act is a new climate law passed in December 2020.

Identifying and Quantifying Fugitive Emissions from Industrial Refrigeration Systems

Industrial ammonia refrigeration systems vary widely in their engineering design, size, scope, and technology features. However, they universally experience some level of refrigerant loss throughout their operational life. Refrigerant losses from industrial ammonia refrigeration systems originate from any number of sources including uncontrolled releases from incidents and accidents, intentional releases during maintenance activities, and fugitive emissions.

EPA Grants IIAR’s Petition for Increased Hydrofluorocarbon Restrictions

The Environmental Protection Agency has granted a petition from the International Institute of Ammonia Refrigeration and its industry partners to use the agency’s authority under the American Innovation and Manufacturing Act to restrict the use of hydrofluorocarbons within the refrigeration sector.

CO2 Standard Provides Guidance on Growing Segment of the Industry

The International Institute of Ammonia Refrigeration has released its safety standard for CO2 closed-circuit systems. The standard covers all phases of the CO2 system lifecycle, from design, installation, and start-up to inspection, testing, and maintenance. It encompasses the CO2 portion of a cascade system, systems using CO2 as a secondary fluid, systems operating part- or full-time in the transcritical cycle, and heat pumps.

As HFCs are Phased-Down, Disincentives for Ammonia Must be Avoided

With the passage and ongoing implementation of the American Innovation and Manufacturing (AIM) Act at the federal level, some states are also taking actions to phase down hydrofluorocarbons (HFCs). As policymakers move away from HFCs, it is also important that ammonia policies be kept in an appropriate balance, to avoid unintended consequences of policies that may serve as disincentives for facilities to move to natural refrigerants.
