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.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
