HVAC heat exchanger coils
Heat exchanger coils benefit from smaller diameter copper tubes
The International Copper Assn. (ICA) has announced a heat exchanger coil technology that benefits from smaller diameter copper tubes. Heat transfer from the refrigerant to the tube wall is more effective inside copper tubes with diameters smaller than the conventional diameter. Consequently, coils can be made less bulky and air conditioners with higher energy efficiency can be made smaller and lighter. Coils made of conventional copper tubes are a proven technology with a long, successful, field-tested history. The new coils provide the high durability and performance that is expected from copper tubes but they use less raw material.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
