Reduce energy costs with new compressor

Reduce energy costs with new compressor
Atlas Copco has introduced a Carbon Zero range of air compressors equipped with advanced heat recovery systems proven to recover 100% of the electrical energy input in the form of hot water. The compressors can, as a result, dramatically reduce energy costs for a wide range of industries. The unique compressors are the first in the world to be certified by the TÜV institute as having net zero energy consumption. 

The Carbon Zero innovation provides effective heat transfer, within specific design conditions, of relative humidity so that a considerable proportion of electrical power input can be recovered in the form of hot water at 90°C. This provides significant benefits for industries employing hot water or steam within process operations such as food and beverage, pulp and paper, chemicals and power plants. By using the compressor output hot water either directly, or as pre-heated boiler feed water, the consumption of process heating fuel and its associated carbon dioxide emissions can be dramatically reduced or, in some cases, eliminated altogether. 

The renowned, independent TÜV institute (German Technical Monitoring Association) earlier this year supervised tests on Atlas Copco's oil-free screw compressor series ZR 55 - 750, equipped with built-in energy recovery systems. The tests demonstrated that under specific design conditions, 100% of the electric energy consumed could be recovered for heating water. 

"We are very pleased to offer our customers a compressed air solution that can recover 100% of the input energy," says Stephan Kuhn, President of Atlas Copco's Compressor Technique business area. "Today our customers face stringent targets to reduce carbon dioxide emissions. The Carbon Zero compressor will have significant impact towards preserving the environment and also on our customers' bottom line. Energy efficiency has been at the core of our product development for a long time. The global need to reduce CO2 emissions confirms we have been, and are, on the right track."

Energy saving in compressed air systems is vital since energy consumption typically represents over 80% of a compressor's lifecycle cost. Compressed air systems on average account for approximately 10% of industrial electrical power consumption, but it can represent as much as 40% of a plant's electricity bill. That is why Atlas Copco continues to be an innovator in energy-efficient compressed air solutions for many years.
