Established in 1994, Mohawk Innovative Technology, Inc. (MiTi) is the world’s leading authority in developing oil-free, high-speed rotating machinery employing compliant foil air bearing technologies. Using our proprietary know-how, company trade secrets, proprietary design software and patented technologies, MiTi has developed a family of CleanTech, high efficiency, oil-free rotating machinery products that include renewable energy turbogenerators, oil-free turbocompressors/blowers and electric motors. Each of these novel, made in the USA products combine high power density and high-speed permanent magnet motor elements, advanced Variable Frequency Drives (VFD) and MiTi’s patented and world-leading, 4th Generation, oil-free compliant foil bearings. By integrating these key, state-of-the-art technologies and components, compact and reliable variable speed machines with electromechanical efficiencies, higher than any other machine on the market today, are possible. Besides achieving high efficiency, MiTi’s oil-free systems offer substantial environmental benefits by eliminating hazardous waste oil disposal concerns and lubricating oil spills. MiTi oil-free system designs result in durable machines with low operating and maintenance costs.
Most recently, MiTi has expanded its capabilities to include the design of centrifugal compressors, volutes and diffusers, as well as turbine nozzles for radial inflow and axial turbines. To compliment our rotor bearing system tools, we use advanced aerodynamic analytical and finite element structural analysis capabilities.
Each MiTi machine uses our patented 4th Generation compliant foil bearings. These self-acting hydrodynamic bearings operate without an externally pressurized air source, require no supporting lubrication system, have no known speed limit and are crafted by MiTi’s manufacturing team in Albany, New York. In operation, the shaft glides on a thin film of air or process gas, virtually eliminating drag on the rotor. With little or no drag, it is possible to take advantage of efficiencies that come from operating at very high speeds. To accommodate tens of thousands of machine start/stop cycles, MiTi has developed a family of flexible, low friction and wear resistant bearing coatings for temperatures from cryogenic to elevated. Additionally, MiTi® foil bearings have high levels of damping and variable stiffness to ensure smooth running, durable machines.
Mohawk Innovative Technology Inc., a leader in Oil-Free innovations, is proud to have been providing high speed, extreme environment, Oil-Free solutions since 1994.
