New and Underutilized Technology: Water Cooled Oil Free Magnetic Bearing Compressors

The following information outlines key deployment considerations for water cooled oil free magnetic bearing compressors within the Federal sector.

Benefits

Water cooled oil free magnetic bearing compressors (60-80 ton and 150 ton) are small, light, quiet, and have a low startup draw. They come with onboard variable frequency drives and microprocessors.

Application

Water cooled oil free magnetic bearing compressors are appropriate for housing, service, office, research and development, school, prison, and hospital applications.

Key Factors for Deployment

Water cooled oil free magnetic bearing compressors are most applicable, but not limited to, the following conditions:

  • Year-round cooling requirements
  • Long run time at partial load
  • Chiller retrofits
  • Compressor replacements
