My name is Torie J. Fidler, and I own Universal Dry Ice Blasting. My family started the very first U.S. Dry Ice Blasting Service Company in 1992. We are a Nationwide Dry Ice Blasting Service Contractor located in Southern California. We have 29-years of Dry Ice Blasting experience in the Industrial and Power Generation field. Our team of Dry Ice Blasting Experts can be on your site in 24 to 48 hours for Emergency Response. Please contact us with any questions. 760-525-8380 or Torie@universaldryiceblasting.com

Hydroelectric Generator Cleaning

We clean Hydroelectric Generators using the Dry Ice Blasting process. My Father, brother, and I began cleaning generators for SCE at Big Creek with Electrical Engineer Mr. Don Frapwell. Don taught us how to clean generators thoroughly to increase Megger readings and prolong healthy stator core temperatures. 

Clogged Air-Cooling Ventilation Channels

We faced one major issue while cleaning these Gentle Giants; Clogged Air-Cooling Ventilation Channels on the Stator. We used bottle brushes to poke the air cooling ventilation channels while the rotor was still in the unit. My brother and I were shoulder deep in the unit with our faces pressed against the spider wheel cooling ring while poking each individual air cooling ventilation channel on the stator; (there are only about 10,000 air cooling ventilation channels per unit?) My brother said, “There has got to be a better way!”

Cleaning Hydroelectric Generators without Removal of the Rotor

We’ve Industrialized our Dry Ice Blasting Machines by increasing the air and ice volume output, which allows us to cover more area faster. We also engineered special tooling that will enable us to clean the stator face and air-cooling ventilation channels. The clogged air-cooling vent debris is pushed into the pit or inspection window area and vacuumed up later. We can clean most hydroelectric generators with the rotor in place. This process saves companies so much money on time and staff hours it takes to pull the rotor and reassemble. We are the only company that can successfully clean with the rotor in the unit. No longer do you have to wait for your 10-year rotor pull to clean a filthy unit.

Since 1992 we have successfully cleaned and reinsulated over 400 hydroelectric generators using this process, and today Dry Ice Blasting is the number one generator cleaning process in the world.
