This document discusses Turbo Oil-Free Compressors for chillers. It notes that magnetic bearings allow for extremely high speeds of up to 200 m/s without lubrication. This results in reliable, low maintenance systems with high efficiency. Applications include replacing old centrifugal chillers or adding backup chillers. The compressors come in a range of sizes from 265-1055 KWc and can be used for both water-cooled and air-cooled systems. Installation involves removing an old compressor and installing the new one along with any necessary piping or electrical work.
11. The concept of magnetic bearings has been around
for at least 100 years. For many of those years,
though, it was the stuff of university experiments and
studies. However, as computing power has improved
so has the viability of using magnetic bearings in
commercial applications
12. The progression in magnetic bearing technology has followed the
evolution of computer technology. The improvement in electronics and
software has enabled better monitoring and control of motion. And
magnetic bearing technology has been both the beneficiary of this
technology improvement as well as the cause of certain applications
becoming more likely to benefit from magnetic bearings. Especially for
industrial machinery, increasingly environmental impact and the cost of
energy are becoming the top priorities. In these applications, magnetic
bearings can provide higher speed operation with greater reliability and
efficiency.
13. Perhaps the greatest benefit of magnetic bearings is their
ability to rotate at extremely high speeds. The bearings
themselves are limited by the strength of the material to a
peripheral speed limit of 180 m/s. For special applications, it
is possible to increase this limit to 200 m/s with more exotic
materials. Another factor is the nearly frictionless
performance of the bearings which is the direct result of the
rotor floating on a contact-free magnetic field. The
elimination of moving mechanical components also means
that there is no lubrication required for the bearing system,
which makes it a very clean system to operate. All of these
factors make magnetic bearings highly reliable, which
drastically reduces maintenance requirements. Magnetic
bearing systems also have low vibration levels even during
high-speed operation, and low audible noise levels.
