The next generation of chiller design is available now, and it features the principal of magnetic levitation. The chiller compressor’s primary moving parts, the turbine and shaft, are centered, spun, and operated in an electromagnetic field rather than through the use of mechanical bearings. This concept has been around since the 1940’s, but has only recently become a usable technology with the advent of nanotechnology and the electronics needed to operate a shaft designed to microscopic tolerances.
With a magnetic field supporting the moving parts, there is no friction and no wearing out of parts. The need for an oil lubricating system is eliminated, as is an oil-maintenance program that results in the disposal of harmful chemicals. The equipment is more efficient and also runs much cooler which can allow the use of more air-cooled models, eliminating the need for cooling towers and the chemicals they ultimately require. Noise and vibration are much less than mechanical equipment, reducing the need for expensive attenuation, isolation mounting, and special connections. Many major manufacturers offer magnetic bearing chillers right now, and their size and configuration variety offers great flexibility in design.
