Dry Ice Cleaning
Reliable, Non-Conductive Cleaning for High-Voltage Systems
High Voltage Dry Ice Cleaning
At DDP Technology, we provide advanced Dry Ice Cleaning services to safely remove contaminants from energized electrical equipment rated up to 34.5 kV. This proven and non-conductive cleaning method eliminates dust, dirt, salt spray, and ash—restoring dielectric strength and preventing electrical breakdowns and flashovers.
How Dry Ice Cleaning Works
Our process uses solid CO₂ pellets or shavings blasted through an insulated wand under high pressure:
Compressor pressure:
-
150 PSI
Flow rate:
-
350 CFM
When CO₂ particles strike the surface, they sublimate directly from solid to gas, creating a triple-action cleaning effect:
Thermal Shock:
-
Extreme cold (–109.5 °F) fractures contaminant bonds.
Gas Expansion:
-
Expanding CO₂ gas lifts debris from the surface.
Kinetic Force:
-
High-speed particles blow contaminants away completely.
This process leaves no secondary waste and requires no de-energization—making it ideal for live electrical equipment maintenance.
