Energy efficiency

Oil-free compressors

1 million tons of CO₂ are saved every year through the Danfoss Turbocor compressors that are installed in commercial buildings worldwide. Today, far less than 1% of commercial buildings have indoor climate systems with oil-free, variable speed compressors. The potential is huge. In the US alone, 950 million tons of CO₂ could be saved every year, if all commercial buildings had systems with this kind of compressor¹.

The Danfoss Turbocor compressors are the world's first completely oil-free compressors. They are specifically designed for the heating, ventilation, air-conditioning and refrigeration (HVACR) industry and can reduce up to 35-50% of the energy consumption in systems in commercial buildings. The centrifugal compressor contributes to a smaller energy bill thanks to its high efficiency. It works without using oil as a lubricant. Instead magnetic bearings replace the oil. This reduces the friction losses making the compressor more efficient. The oil-free operation also reduces complexity while at the same time cutting costs.
