Curb Your (People’s) Enthusiasm
Having enthusiasm LESSON for your work and a desire to accomplish something is good. I have worked with many people in the industrial refrigeration field that are enthusiastic, fun to be around, and even in challenging or stressful situations they have worked through issues in a positive manner.
Read MoreLowering Charge with Advanced DX Ammonia
New technology that utilizes low charge direct expansion at low temperatures can improve safety and reduce the first cost of installation, while significantly reducing the ammonia charge required on site. That, in turn, can reduce the regulatory burdens associated with large ammonia inventories.

Implementing Real-Time Profitable Safety
Profitability is always an important issue, and plant managers are frequently faced with addressing safety challenges while striving to achieve higher levels of production and efficiency. But instead of looking at safety and production separately, as many facilities often do, the two can be combined into one dynamic process called real-time profitable safety.

Fred Walker was known for his unfailing work ethic, integrity and commitment to the refrigeration industry, in which he was involved for more than 40 years. “A saying Fred used was, ‘The only thing better than coming in early is staying late,’ and he lived it.
Read MoreTwo Years Later: Texas Explosion is Catalyst for Change
For the ammonia and chemical industry, the ammonium nitrate explosion in West, Texas, in 2013 has served as a catalyst for change, causing several government agencies to examine their policies and update safety regulations.
Read MoreCOMPARING EVAPORATIVE AND AIR COOLED CONDENSING FOR AMMONIA SYSTEMS
Ammonia refrigeration systems use evaporative cooled condensers almost exclusively. Due to the large size of most ammonia systems, historical context, and industry perceptions regarding performance and efficiency, air cooled condensing is seldom considered for ammonia.
Read MoreIIR Holds Sixth Refrigeration Technologies Conference
The International Institute of Refrigeration, IIR, said its sixth Ammonia and CO2 Refrigeration Technologies Conference clarified future uncertainties regarding both the Montreal and the Kyoto Protocols and environmental regulations applicable to natural refrigerants.
Read MoreChairman’s Message
This month marks one of the most productive and interesting times of the year for IIAR. The March annual meeting is behind us, and we’re at the beginning of the organization’s new leadership cycle. That means it’s time to build on all the momentum we created in the last year, and at the same time look ahead to a few new goals.
Read MorePresident’s Message by Dave Rule
Throughout this edition of the Condenser, you’ll see a common theme: change. New technologies are opening the door to new types of customers and applications for ammonia and other natural refrigerants.
Read MoreStandardizing a Customized Industry
The move towards lower charge has spurred demand for products like standardized package systems that promise solutions to at least some of the industry’s biggest problems. But exactly how those products will develop, and who will take them to market is yet unclear.
Read MoreIIAR Shatters Attendance Records, Sets New Goals at Annual Conference
The International Institute of Ammonia Refrigeration drew record attendance again this year at the 37th Annual IIAR Conference & Exhibition, an event that marked a variety of transitions and new initiatives for the association this year.

Routine 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 floors, freezers and coolers to facility rooftops. The reasons for the transition have been practical.
Read MoreSmaller Facilities Shouldn’t Overlook Safety Planning
When it comes to safety, prevention is the most important factor in avoiding potential consequences. Whether a facility is working with 900 pounds or 90,000 pounds of ammonia, the risks of an incident are similar.
Read MoreREFRIGERANT AND REGULATORY DEVELOPMENTS: CHANGES IMPACTING THE OPPORTUNITIES FOR NATURAL REFRIGERANTS
As recently as five years ago, air-conditioning and refrigeration applications were dominated by a handful of refrigerants – ammonia in large industrial systems, HFCs like R404A and HFC-134a in stationary and mobile refrigeration and air-conditioning, and R410A in stationary air-conditioning applications. Meanwhile, the use of HCFC-22 was declining as it was being phased-out by the Montreal Protocol agreement.
