Danfoss’ VZH inverter scroll compressor uses a brushless interior permanent magnet (IPM) design and its variable spreed technology provides infinite and smooth capacity modulation. Courtesy: DanfossDanfoss’ VZH inverter scroll compressor uses a brushless interior permanent magnet (IPM) design and is optimized for different pressure ratios to deliver energy savings of more than 30% when compared to a unit equipped with a fixed or mechanically modulating compressor. In addition, the variable speed technology provides infinite and smooth capacity modulation, delivering precise temperature control within 0.1 F of the setpoint. This is ideal for applications that require precise temperature and humidity control, including IT equipment, industrial processes, museums, and libraries. With cooling capacities ranging from 13 to 26 TR, the VZH provides the largest cooling capacity with a single variable speed hermetic scroll compressor and the widest variable speed compressor range in the market for air-conditioning applications. A 4:1 modulation ratio allows the VZH inverter scroll compressor to modulate from 25 to 100 rps for greater savings. Pre-equipped tandem capability extends the cooling capacity to 52 TR and a 12% to 100% stepless modulation for a variety of demanding applications where low part-loads are needed. The VZH is available with optimization at two pressure ratios for either chiller or rooftop applications.

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.
