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 the energy consumption in systems in commercial buildings by up to 35-50%.
The centrifugal compressor contributes to a smaller energy bill thanks to its high efficiency, working without using oil as a lubricant. Instead magnetic bearings replace the oil, which reduces the friction losses and makes the compressor more efficient. The oil-free operation also reduces complexity, while at the same time cutting costs.
The pay-back time typically varies from 1 to 3 years, depending on the application.
