Introduction Frictionless Compressor TechnologyA new compressor technology introduced during the 2003 International Air-Conditioning,

Heating, Refrigerating Exposition (AHR Expo) in ChicagoIt may have a help in future of mid-range chillers and rooftop applications in water-cooled,

Evaporatively cooled, and air-cooled chilled water and direct-expansion (DX) systems.

Frictionless compressor is run by uses of magnetic bearing technology

This compressor was awarded the first AHR Expo Innovation. A ward in the energy category,

as well as Canadas Energy Efficiency Award for its potential to reduce utility-generated

greenhouse- gas emissions.

What is frictionless Compressor

Friction less compressor are made up of friction lessbearing called magnetic bearing.

Its free from lubricants bearing and its eliminatesfriction and have low noise level s compare to the

conventional compressor. Its design as such way so that its free from oil ,and

design gracefully and stylish.

Its Helps in improve efficiency on air cooled or

water cooled Dx systems Its provides Digital control system provides very

easy controlling managing and monitoring.

Its consumes less power and lubricant then other

conventional compressor.
