President’s Message by Dave Rule
The International Institute of Ammonia Refrigeration is growing, both within the United States and abroad, thanks to the use of natural refrigerants and IIAR’s efforts to bring awareness of their value to other countries.

As I wind up my year as chairman of IIAR, I look back and see all the wonderful accomplishments that you – our members and committees have achieved, setting the stage for even more in the year ahead.
Read MoreOLD GAME, NEW CARDS
Maintenance costs, particularly for labor, are increasing, and the traditional material specified for piping and valve systems – painted carbon steel – is changing as end users search for solutions to minimize maintenance and increase reliability. “The presence of corrosion creates specific issues, particularly with uninsulated valves and controls, that must be managed by those in the refrigeration industry,” said Bob Czarnecki, a member of the International Institute of Ammonia Refrigeration board of directors.

The Sustainability Challenge
To date, activities within the International Institute for Ammonia Refrigeration have dealt exclusively with ammonia safety and ammonia refrigeration systems. That’s who we are, where we come from and what we’ve done well. Recently, however, it has become clear that IIAR needs to take up the challenge of promoting the safe and efficient use of all the natural refrigerants – ammonia, carbon dioxide, hydrocarbons, air and water.
Read MoreCosta Rica Adopts IIAR Standards
In late January Costa Rica officially adopted several standards from the International Institute of Ammonia Refrigeration to govern ammonia refrigeration facilities in the country. Costa Rica is the first to take such a progressive move in Latin America, and others in the region are taking note.

Trying to understand and properly apply standards and regulations is not only a time consuming effort, but also challenging. The Occupational Safety and Health Administration (OSHA) has Standard 29 CFR 1910.147, titled “The control of hazardous energy (lockout/tagout)”, which is commonly referred to as “Lockout/Tagout”.
Read MoreFoundation Research Projects Summary
The Ammonia Refrigeration Foundation is dedicated to furthering the advancement of the knowledge and technology that drives the growth of natural refrigerants. The Foundation’s three ongoing research projects are helping the industry address and solve specific technical problems as well as contribute new information to the code and regulatory communities. Here, the Foundation’s research project leaders give a summary of where and how project information is being produced and used.
Read MoreMachinery Rooms in Europe and USA: Sprinkler Systems
Machinery rooms are enclosed zones with mechanical ventilation, separated from public space and accessible only to authorized personnel. They serve primarily as dry and protected places for the components of a refrigeration system, mainly compressors and pressure vessels, but also additional equipment, for example in secondary systems the evaporator and/or water cooled condensers.
Read MoreWelcome to the 2019 IIAR Natural Refrigeration Conference & Exhibition!
We are coming off of a very successful conference in Colorado Springs last year where we celebrated our 40th IIAR Annual Conference. This year we are pleased to return to Phoenix after many years. The last time we were here was in 1981 and the conference, our organization and our industry looked very different.
Read MoreIIAR’s Conference Tech Papers Expand to Include Commercial Sector
One main focus of the technical program this year was to help educate commercial decision makers and designers. “Commercial end users are starting to become more interested in natural refrigerants,” Eric Smith, IIAR’s vice president and technical director, said. “Now people are beginning to wonder about their applications – how well it’s been going, the difficulties they’ve encountered and which natural refrigerants they should choose.”

Charitable Contributions from IRAs
You must be 70½ or older in order to be eligible to make QCDs. You simply instruct your IRA trustee to make a distribution directly from your IRA (other than SEP and SIMPLE IRAs) to a qualified charity. The distribution must be one that would otherwise be taxable to you. You can exclude up to $100,000 of QCDs from your gross income each year.
Read MoreJohn Yencho Retires from Hansen
We respectfully announce the retirement of one of Hansen’s most dedicated and long-term contributors - John Yencho. John has been a key contributor to our success over his 34+ years of service and the industry. Although he is officially retiring, we expect him to remain involved with Hansen’s on-going innovation efforts.

Was it Communicated?
Some may recall the statement made in the 1967 “What we’ve got here is failure to communicate.” Clear and understood communication is important in almost all interactions we have. As important as good communication is, we still have challenges in making it happen.Some may recall the statement made in the 1967 “What we’ve got here is failure to communicate.” Clear and understood communication is important in almost all interactions we have.

Supreme Court Declines to Hear HFC Case, EPA Proposes Removing HFC Leak Requirements
On January 18, 2019, President Trump signed legislation to extend the authority for the Chemical Facility Anti-Terrorism Standards (CFATS) program. CFATS, administered by the Department of Homeland Security (DHS), was set to expire on January 19th unless legislation was enacted to continue its authority. Industry and DHS called for reauthorization to prevent a lapse in authority.
