Heat pump scroll compressor range extended
The Performer PSH heat pump scroll compressor by Danfoss extended its range with six smaller capacity models, giving the compressors a heating capacity range of 19 to 80 kW.
Danfoss extended the range of its Performer PSH heat pump scroll compressor, adding six smaller capacity models to the product offering. As a result, Performer PSH heat pump scroll compressors now offer a heating capacity range of 19 to 80 kW, thanks to liquid injection technology. 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 mean the compressor can be applied in colder regions. Performer PSH compressors can operate year-round and need no furnace backup. Compressors in the new range require fewer system components, which reduces costs. All models achieve a compressor coefficient of performance (COP) that surpasses requirements for the Eco label (3.4), with some air to water heat pumps posting a COP of 4.11 (equivalent to 14.02 EER).

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.
