The cold does not crack anything in a generator. Dust re-contamination? Just make sure you have everything that you don't want dust to get on covered with poly.

Waste of money for windings and poles.Can and will damage insulation if old, and cannot reach into tight areas, or where a hand and rag cannot fit. May be okay for some situations, it definitely is not the miracle cure all a salesman will tell you. Try fixing oil leaks as well as a system to recover carbon dust from brushes.

@pgnedved

To date we have never had a damage claim, nor do we have sales people who make idiotic statements that would lead anyone to believe this process will fix oil leaks or recover carbon dust. But, dry ice blasting will remove every bit of carbon and oil from the inside of the generator when the generator is disassembled.

It will get the job done better and faster than 10 people with a rag in each hand.

Y cant we use sand blasting or Aluminium Grit Blasting. How is Dry ice better the the above two??

[Cliffordf1]

@mandapakaraju

Dry ice blasting is not abrasive. Sand and aluminum grit are abrasive. Residual abrasive blast media can and does lead to long term maintenance problems.

[mandapakaraju]

My doubts are this, Doesn't dry ice damage the generator coil winding? I can understand the mechanical side of the turbine but the generator is a bit too delicate to use dry ice. Can u please clear my doubts??

[Cliffordf1]

It does not damage the windings because the dry ice is changed to fine granules prior to contact with the surface. Once contact is made the dry ice sublimates instantly into a gas. Look again and you will see a deflector on the end of the nozzle.

sand blasting damages the surface of the target and leaves a mess....ice blasting no damage no clean up

[albduke1]

A lot of the big electric motor shops use this.the cold doesnt crack the windings,insulation?How do you keep dust recontamenation down.in other words how keep dust build up on windings from blowing all over everything?

@enviroteksolutions There is some cleanup... We had a generator cleand my dry-ice and it was the "apprentice" (me) that have to clean the room behind the stator for debree that was bushed back triugh the generator and under. An the most fun was when the job was completed and there was 200kg of dry ice left for us to play with ^^

[krishrajaganapathy]

please suggest a solution for cleaning the rotor of the generator of 22.9 MW capacity without disassembly. A lot of dust accumulation is suspected due to IR values.

thank you,
