President’s Message by Dave Rule

It’s that time of year again, and I’m happy to welcome all IIAR members back to our most important event – the IIAR annual conference and exhibition. Before I get into the exciting things we’ve got in store for you as an organization this year, I’d like to take a minute to recognize all our sponsors and exhibitors. It is their support that provides the backbone for this annual event, sponsoring food and coffee breaks, not to mention our exhibit hall – and everything else that makes this one of the premier events in our industry.

Chairman’s Message by Walter Teeter

It’s amazing how quickly a year can go by. Our 2018 annual conference is here already, and while that means this is the last annual meeting during my term as Chairman, this year’s conference represents just the beginning of many exciting developments for IIAR and its members.

NH3 | CO2 TAKE GOLD

Ice rinks from community recreation facilities to the National Hockey League are moving to natural refrigerants such as ammonia and carbon dioxide as they replace aging facilities and deal with the mandatory phase out of R-22, a hydrochlorofluorocarbon that has been widely used at ice rinks across North America.

Europe’s F-Gas Phase-Out, Price Increases, Leave the Industry Looking for Solutions

In Europe, the phase out of fluorinated gases with high global warming potential, known as F-gases in Europe and HFCs in the U.S., is resulting in severe shortages, causing prices to skyrocket and creating challenges for those that operate and maintain the systems.

CONFERENCE CHAIR’S MESSAGE

It’s the beginning of a new annual conference for all of us at IIAR, and that means it’s time to meet new colleagues, network, and catch up with friends and business partners at our industry’s largest event. Welcome to the 2018 IIAR Natural Refrigeration Conference & Exhibition!

ARF Message

The International Institute of Ammonia Refrigeration, in partnership with other industry leaders — including The Foundation, RETA, IIAR, GCCA, Lanier Technical College, and Fastport — has created an apprentice program for mechanics and technicians to help bolster the refrigeration workforce. The program is designed to train ammonia refrigeration technicians in all phases of their careers and combines well-developed on-thejob learning with related instruction.

From Threat Assessment to Employee Engagement: IIAR Tech Papers Unveil Research, Analyze Data

Utilizing bow-tie graphics to assess and prevent potential threats to an industrial ammonia refrigeration system, the importance of employee engagement and building relationships with first responders, and the benefits of ammonia scrubbing with C02 are among the technical papers and workshops that will be presented at this year’s annual IIAR Natural Refrigeration Conference and Expo.

Efficiency Can be Just Another Controllable Cost

Energy efficiency can be achieved in ways other than with new technology. It can also prove to be a controllable cost, just as with labor and equipment. By developing an energy management system that establishes clear, measurable goals for energy performance, end users of industrial refrigeration facilities can realize a significant reduction in energy consumption, delivering cost savings that fall straight to the bottom line.

Little Details Add Up

When big things happe they really draw our attention, but in most cases it’s the little things we miss that can result in unexpected and sometimes undesirable results. We might breeze along taking account of larger items, not realizing or taking time to think that little details can make a big difference.

Social Security: Claim Early and Invest Versus Delaying Receipt for Increased Benefits

Financial Advisors are occasionally asked to provide an analysis of the potential results of claiming Social Security early and investing the proceeds versus delaying receipt for increased benefits, which can be claimed as late as age 70. The following are the reasons that delaying social security income can be a prudent strategy.

Using the Right Type of Monitor for CO2

The use of CO2 is becoming common in the industrial refrigeration industry, especially with cascade refrigeration systems. But many people are not as familiar with CO2 as they are with ammonia, some believing that the only respiratory issue with CO2 is that it is an inert gas like nitrogen or argon.

Appeals Court Denies Rehearing of Ruling Against EPA Regulation of HFCs

On January 26, 2017, the United States Court of Appeals for the District of Columbia Circuit denied petitions requesting a rehearing by the full court of a decision finding that the Environmental Protection Agency (EPA) had exceeded its authority by regulating the use of HFCs through the Significant New Alternatives Policy program (SNAP).

Energy Performance of Low Charge, Central Type, Dual Stage NH3 Refrigeration Systems in Practice

In the wake of the pending global phase-down of HFCs due to their contribution to global warming, users and owners of refrigeration systems are faced with decisions that at times appear difficult. These decisions relate to whether or not users continue to employ HFC-based refrigeration systems, switch to low GWP synthetic refrigerants or consider future-proof natural refrigerants such as NH3 , CO2 , hydrocarbons, water, or air in their new and/or expanded systems. In this decision-making process, one very important factor is often either overlooked or underestimated. This factor is energy performance—particularly the energy performance of low charge NH3 systems.
