Sidebar: Synergism

NASHVILLE, Tenn. - Look up terms like “synergism’ and ‘segue’ in a dictionary and you might see, as an example, what happened at the recent International Institute of Ammonia Refrigeration conference.

The four-day conference is one of the premiere places to learn about the latest trends in industrial refrigeration. A long time end user member of IIAR is General Mills Inc.

So on the first full day of the conference, the plenary speaker was John Church, vice president of global engineering for General Mills. He talked about how the company uses ammonia in many of its production facilities and how decisions are made in choosing ammonia or another option.

Then as the conference moved along, General Mills brought in some 50 of its engineers to catch a portion of the conference, especially to visit the exhibit area, which had more than 100 manufacturers and educators showing products and services. Then as the IIAR conference concluded on a Wednesday morning, the General Mills engineers started several days of its own meetings that afternoon.
