Water and electricity don’t mix.

But as we all know that doesn’t mean electrical plant and equipment doesn’t get dirty and need cleaning up from time to time.  This has always proved a difficult and time-consuming process, until Dry Ice Blasting…..

Non-Conductive, moisture-less cleaning.

Dry Ice Blasting solves the challenges of cleaning on or around electrical, live and sensitive plant.  As widely documented in the industry, Dry Ice Blasting is one of the best cleaning methodologies for:

Electric Motors

Cleaning with Dry Ice Blasting allows electric motors to be cleaned in place, saving time and money through reduced labour and plant downtime. The dry process means no secondary media waste (no water or chemicals), no drying out time required and minimal clean up. The non-abrasive nature of dry ice cleaning means no damage to small parts.


Dry Ice Blasting is ideal for cleaning electrical generating equipment, reducing overheating issues and improving output efficiency. Dry Ice Blasting also allows the units to be cleaned in place without damage to cables and insulation.

Insulators & Switches

With Dry Ice Blasting, dirt accumulation that can cause arc overs is removed with no equipment downtime. Because the process is dry, there is no requirement to dry out the equipment after cleaning and greatly reduced chance of corrosion from moisture.

Cable  Trays

Dry Ice Blasting is the answer to cable tray cleaning. Cleaning with dry ice removes accumulated dirt, dust, grit and other foreign materials simply and efficiently without damage to the cable insulation from solvents or cleaning tools.

Stator and Rotor Cleaning

Dry Ice Blasting quickly removes carbon deposits from winding’s and other dirt build up on the stator and rotor. Oil and greases are removed from the bottom of the rotor without damage to the insulating coatings. 


  • Dry on contact. There is no dry out process required.
  • No secondary waste. No disposal issues.
  • Faster and more thorough than other cleaning methods
  • No potential damage to any components.
