The Solar Impulse Foundation endorsed the Turbocor oil-free compressor as one of the top 1,000 solutions for protecting the environment. Manufactured by Danfoss, the Turbocor compressor has been installed in water- and air-cooled chiller systems more than 68,000 times worldwide, says the company.

In evaluating the technology, the Solar Impulse Foundation awarded the compressor range the high score of 4.0 assessed on the criteria of technological feasibility, environmental and socio-economic benefits and profitability. The oil-free, magnetic bearing technology reduces energy consumption up to 40 percent compared to traditional fixed-speed compressor technology, says Danfoss, and provides annual emission savings of up to 194 metric tons of CO2.

Danfoss is the second company in the world that has three products selected by the Solar Impulse Foundation.
