PolarFit® Size Reduction Systems

A cost effective way to achieve required particle sizes and production rates

Air Products’ PolarFit® cryogenic grinding solutions can help you grind more effectively and efficiently, particularly for heat sensitive or tough-to-mill materials. Whether you have an existing cryogenic or ambient milling system that you need to upgrade, or plan to install a new system, we can help.

Webinar Replay: The Fundamentals of Cryogenic Grinding

Our systems use liquid nitrogen or liquid carbon dioxide to cool down feed material prior to and/or during milling to either help prevent its melting or decomposition, or achieve embrittlement. While each product is unique, the major benefits of cryogenic grinding are the same:

  • Higher yield of particles in your target range
  • More uniform particle size distribution
  • Higher production rates
  • Improved product quality
  • Improved process safety due to the nitrogen inertness

From cryogenic services, industrial gas supply, to complete cryogenic systems, you can rely on Air Products experienced engineers to help you find the best solution for your process.
