Cryogenic (CO2-Dry Ice) Cleaning for Electrical Rotating Machines

Cryogenic Cleaning Method

How it works ….

  • Step # 1 - Energy Transfer : Dry ice is propelled outside the blasting at high speeds to impact the surface. The force of this impact is the primary means of cleaning.
  • Step # 2 - Micro Thermal Shock : The cold temperature of the dry ice hitting the contaminant creates a micro thermal shock at -79 degrees centigrade thereby breaking the bond between the surface contaminant and the substrate.
  • Step # 3 - Gas Pressure : Sublimation of the dry ice on impact forces off the contaminant from behind because of expansion form the solid to gaseous state.

The advantages:

  • Post dry out not required
  • Not abrasive in nature does not damage the substrate
  • Ideal for in position cleaning – reduced down time
  • Environmentally Friendly
  • Provides a cleaner Clean
  • Insulation values improve immediately on cleaning
  • Non-flammable and nonconductive
