The checklists contained in IIAR 6 Appendix B are derived from a legacy document named IIAR Bulletin No. 109. For years, the Bulletin 109 checklists, or B109s, served as the gold standard for documenting annual mechanical integrity inspections for ammonia refrigeration equipment.

In 2019, IIAR retired Bulletin 109 when the first edition of Standard 6 was published. Standard 6 addresses the minimum requirements for inspection, testing, and maintenance of ammonia refrigeration systems, and includes slightly altered versions of the B109s in Appendix B.

The checklists are typically two pages. The first page contains contact and equipment information and the second page has the inspection checklist. While all the information on the second page will change year-to-year with the equipment inspection, much of the information on the first page should stay the same. For this reason, you may only have to fill out the first page for each piece of equipment once. For subsequent years, you should only have to fill out the second page.

The simplest part of completing a pressure vessel checklist is filling out the contact information. Each IIAR 6 checklist requires the inspector to indicate the location, owner, and physical address of the system. The contact name and phone number should be the facility representative responsible for ensuring the inspection is completed. Additionally, the inspector must write his or her own name and the date of the inspection. The ID or Tag No. belongs in the upper right corner and can typically be found on the equipment label or P&ID.

The IIAR Condenser Magazine is a quarterly publication that contains technical articles, regulatory and code updates, industry news and information about IIAR activities and publications. It is distributed by email to all IIAR Members and IIAR Contact lists.

The use of natural refrigerants is increasing as governments, investors, and end users work to reduce the use of high-global warming potential refrigerants. Europe has been at the forefront, promoting the use of natural refrigerants through regulations and incentives, but challenges remain in other areas. Those involved in refrigerants globally said it would take increased awareness and, possibly, regulatory changes to facilitate the adoption of lower GWP solutions.

Roger was born in Missoula, Montana, to Jerry and Gwen McMillan. He spent his early childhood in Spokane, Washington, and then Jerry and Gwen relocated their dry-cleaning business to Colville, Washington, where Jerry invented specialized laundry machines and started the Colmac businesses.

Companies nationwide are phasing out high global-warming potential refrigerants as they comply with federal and state regulatory requirements and meet their corporate ESG and climate goals. The natural refrigerant industry is prepared to meet increasing demand.

In October 2023, Environmental Protection Agency (EPA) Administrator Michael Regan signed the Final Rule Technology Transitions authorized under the American Innovation and Manufacturing Act designed to phase down hydrofluorocarbon (HFC) use.

In the ammonia refrigeration industry, maintaining the proper filling levels of pressure vessels is essential for safety, efficiency, and regulatory compliance. Appropriately filled vessel ensures that ammonia refrigeration systems operate optimally, reducing energy consumption and preventing safety hazards

Training is essential for anyone working with refrigerants, and IIAR has a long history of serving as a valuable resource for education and training for its members. The association recently took that support to the next level for Trident Seafoods in Alaska.

A new report prepared for the New York State Department of Conservation highlights opportunities for and barriers to the adoption of natural refrigerants, outlines the availability of natural refrigerants by end-use sector, provides recommendations and considerations for policymakers to address the obstacles to natural refrigerants adoption, and lists ideas for pilot projects.

IIAR and the Natural Refrigerant Foundation held their board meetings in Dallas in October. Gary Schrift, president of IIAR, said the meetings were well attended. During the sessions, committee chairs provided updates on the critical work they are doing.

The 2024 IIAR Natural Refrigeration Conference & Heavy Equipment Expo, March 24-27, in Orlando, will bring several significant changes from previous years, including an updated schedule and an exclusive Natural Refrigeration Foundation Fun Day.

The IIAR HC (Hydrocarbon) Standard has continued to move forward and was recently released for its first public review. The 45-day public review ran from July 7 through August 21. As of early August, the standard had received 92 comments.

IIAR has recently had its June board meeting, and the board took action on several critical IIAR standards and initiatives, welcomed new committee chairs, and celebrated members who have devoted valuable time and expertise to the industry.

All parents aspire to build a life for their children that is better than the one they lived. One way many parents seek to accomplish this worthy endeavor is by building a strong financial legacy. If you are fortunate enough to accumulate more wealth than previous generations of your family, you should work diligently to ensure that this wealth will translate to a financial legacy built to last not only for your children but for generations to come.

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.

Over the past 20 years or so the use of CO2 refrigerant as the first stage of CO2/HFC and CO2/NH3 cascade systems has increased significantly. The use of two-stage transcritical CO2 systems, which are invariably air cooled, is an increasing trend. Frequently, two-stage gas coolers are used with water sprayed on the secondstage air-cooled gas coolers to reduce the gas cooler exit temperature to as low a value as possible.

The International Institute of Ammonia Refrigeration 2023 Annual Natural Refrigeration Conference & Expo in Long Beach, California. The event provided four days of technical knowledge, networking, and industry-sponsored events for those involved in the natural refrigeration industry. Roughly 1,700 attendees took part in the show and IIAR set a new record with its exhibit space.

The Natural Refrigeration Foundation has raised more than $73,000 at its annual golf tournament. The foundation promotes the climate-positive, safe, reliable, and efficient use of natural refrigerants through research and scholarships to develop industry talent, academic alliances, and outreach.

The use of technology in the industrial refrigeration industry continues to increase, and automation and internet control of facilities are becoming commonplace. The benefits of automation and control are massive, but there is also a downside. The systems can be vulnerable to attack, making cybersecurity measures essential to protect against cyber threats.

Heat pumps can significantly reduce energy consumption and greenhouse gas emissions, and the adoption of heat pumps is continuing to increase in both household and industrial applications as technology advances.

The Standards Committee is continuing its work on revisions of several standards, which must be reviewed and revised a minimum of every five years by the American National Standards Institute (ANSI) for IIAR to remain as an accredited Standards Developing Organization (SDO). Updates for each standard were given during the IIAR Standards Committee Meeting at the IIAR 2023 Annual Conference in Long Beach.

The increase in the volume of work resulting from regulatory changes is superimposed on a backset of a) unprecedented instability and b) an increasing and overwhelming number of decisions we are forced to make daily.Generative A.I. is compounding the overwhelm. The number of decisions every day has increased tenfold over the last three years (74%), 78% are bombarded with more data than ever, and 86% say the volume of data is making decisions much more complicated.

On April 7, 2023, the Occupational Safety and Health Administration (OSHA) submitted its latest injury and illness recordkeeping proposal to the Office of Information and Regulatory Affairs (OIRA).
