Heat pump scroll compressor
Danfoss offers the Performer PSH heat pump scroll compressor.
Danfoss’ Performer PSH heat pump scroll compressor features innovative liquid injection technology that delivers a wider temperature envelope than most heat pumps. Four models offer a heating capacity range of 38 to 77 kW at 19.4 to 122 F. The compressor’s 149 F saturated condensing temperature allows for safe hot sanitary water production and comfortable space heating, even with old radiator systems. Evaporating temperatures as low as -22 F means the compressor can be applied in colder regions. Optimized for R410A refrigerant, the Performer PSH also incorporates an operating control system that pilots the liquid injection technology and ensures reliability by keeping the compressor within operating limits. The system also stores operating data and events for improved serviceability while reducing downtime and warranty costs. In addition, an insulated, integrated crankcase heater results in sound levels as much as three decibels lower than equivalent products.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
