Firefighting with Refrigeration
IIAR has had much success in the past 15 years in the model code arena, updating codes to more appropriately regulate ammonia refrigeration. I’m sometimes asked how we were able to sway the opinions of so many fire safety regulators to support approval of IIAR proposals, and the answer, in a word, is “education.”
Read MoreThe Color CONUNDRUM. IIAR DEFINES PIPING CONVENTION
The importance of color coding ammonia refrigeration piping is a generally accepted best practice these days, but the debate over which colors to use has been anything but black and white.

Where’s that vapor going?
Where’s that vapor going? Sooner or later that question must be answered when some type of work is required on an ammonia refrigeration system.

In 2013, the Costa Rican government began implementing its national strategy to eliminate hydrochlorofl ourocarbons while supporting IIAR’s first Industrial Refrigeration seminar in Central America.
Read MoreRoutine Rooftop Maintenance Creates Requirement for Fixed Industrial Stairs
Increased regulatory scrutiny and the growing emphasis on process safety management have spurred a steady relocation of equipment from production room fl oors, freezers and coolers to facility rooftops.
Read MoreEPA Looks to IIAR in HFC Phase-Down Meeting
The search for non-ozone-depleting technologies is intensifying, with ammonia and other natural refrigerants emerging as the most viable solutions for industrial refrigeration, thanks to international treaties that put pressure on countries to phase down CFC’s and identify alternatives.
Read MoreRemembering Don Siller
Whether it was helping friends, family, and colleagues or advancing the interests of the International Institute of Ammonia Refrigeration, people who knew Don Siller described him as someone who was passionate about life.

IIAR Plans Training Collaboration
The IIAR International Committee has been hard at work on several important initiatives since it became a formal working committee in 2012. One of the group’s most important goals in 2013 has been to facilitate training by conducting seminars and providing educational materials to governments and working groups in other countries.
Read MoreTHE HISTORY OF FIRE PROTECTION THE HISTORY OF IN COLD STORAGE FACILITIES
The protection of industrial cold storage warehouses is one of the most difficult challenges facing the fire protection professional.
Read MoreAnalyzing Overpressure Scenarios
When isolating equipment that contains liquid anhydrous ammonia, the potential exists for it to become over pressurized due to thermal expansion effects. The overpressure from liquid expansion could then result in the rupture and loss of ammonia from the equipment. And that rupture and loss, if large enough, could potentially have a serious or catastrophic consequence.
Read MoreChairman’s Message by Bob Port
Summer is typically a time to kick back, relax, and ease up on responsibilities – but that’s not the case for our organization this year. As I continue transitioning to my new role as chairman, I am continually impressed by the whirlwind of important projects taking place at headquarters.
Read MorePresident’s Message by Dave Rule
Throughout this edition of the Condenser, you’ll see a common theme: Progress. Over the past few months, IIAR, and the ammonia refrigeration industry as a whole, have experienced several signs of promise and growth.
Read MoreIIAR Standards Committee Pursues Organization’s Goals
One of the biggest missions of the International Institute of Ammonia Refrigeration is to provide standards that will benefit the ammonia refrigeration industry worldwide.

Congress Considers Modernization of Chemical Security Laws
The Toxic Substances Control Act (TSCA), signed into law in 1976, provides the Environmental Protection Agency (EPA) the authority to control potentially dangerous chemicals in U.S. commerce.
Read MoreDealing With Conflicting Codes and Standards
Although much effort goes into coordinating various documents that regulate ammonia refrigeration systems, perfect harmony isn’t achievable for a variety of reasons. Anyone who designs or operates facilities that utilize ammonia refrigeration knows that we deal with a lot of codes and standards.
Read MoreThe Standard for Tomorrow
In 1974, the International Institute of Ammonia Refrigeration issued IIAR-2, a standard that would uniquely address the design and installation of ammonia refrigeration systems for the first time and establish IIAR as the standards writing body dedicated exclusively to ammonia refrigeration.

Emergency Planning Should Involve Coordination with Local Responders
Coordination with local responders is a basic safety responsibility for any facility, but in some cases, even if a company has a well-articulated emergency plan, the lessons learned from a small incident can reveal much bigger considerations.
Read MoreRemembering Rudy Nechay
Ammonia refrigeration lost one of its most entrepreneurial and dedicated leaders last month with the passing of Rudy Nechay, a man friends and family described as passionate about his work and devoted to the advancement of his industry.
