Dry Ice Blasting for Electrical Equipment & Switchgear
Dry, non-conductive cleaning for switchgear, MCCs, transformers, busbars, and electrical rooms.
Dust, soot, salt, and contamination on electrical equipment increase the risk of arc flash, thermal events, and unplanned outages. Traditional water and chemical methods are usually not an option around energized or recently de-energized electrical gear.
Dry ice blasting is dry and non-conductive, making it well-suited for cleaning switchgear, motor control centers, transformers, busbars, and electrical rooms when paired with proper lockout/tagout, PPE, and clearance procedures.
Where this fits
- Switchgear and MCC cleaning
- Transformer cleaning
- Busbar and bus duct cleaning
- Generator rotor / stator
- Electrical room contamination removal
- Pre-thermography prep
How a Dry Ice Blasting for Electrical Equipment & Switchgear Project Runs
Every project follows the same disciplined sequence — scoped to your facility, your safety program, and your shutdown window.
1. Site Walkdown & Scope
A specialist reviews your equipment, contaminants, access constraints, shutdown window, and safety requirements — by phone, video, or on-site walkdown.
2. Plan, Quote & Schedule
You receive a written scope of work and quote. We coordinate JSAs, lockout/tagout, hot work, confined space, and any plant-specific safety paperwork before mobilization.
3. Mobilization
Our crew arrives with diesel air compressors, blasting equipment, hose, PPE, CO₂ pellets, and supporting tools. Most projects are fully self-contained — no plant utilities required.
4. Cleaning & QC
Trained operators clean in place using non-abrasive dry ice. We work in shifts to match outage windows and document progress as we go.
5. Walkthrough & Turnover
A final walkthrough confirms results with your team. We leave the work area clean — no grit, no media, no slurry to dispose of.
Why Facilities Choose This Method
Dry — No Water
CO₂ pellets sublimate on impact. No water intrusion into bearings, electrical components, or insulation; no drying time before restart.
Non-Abrasive
Helps protect tooling, fins, gaskets, and finished surfaces that grit blasting would profile or pit.
Non-Conductive
Suited for cleaning around electrical components when paired with proper LOTO, PPE, and clearance procedures.
No Secondary Waste
Only the removed contaminant needs to be collected. No spent blast media, no slurry, no chemical wash water.
In-Place Cleaning
Most equipment can be cleaned without disassembly — reducing labor, downtime, and re-commissioning risk.
FDA-GRAS CO₂
CO₂ is recognized by the FDA as Generally Recognized as Safe under cGMP, supporting use on food-zone equipment by trained operators.

Frequently Asked Questions
Does dry ice blasting damage equipment?
Dry ice blasting is non-abrasive. Solid CO₂ pellets are much softer than sand, walnut shell, or soda media. The cleaning action comes from thermal shock and the kinetic effect of sublimating pellets — not abrasion. When operated correctly it removes contaminants while leaving the underlying substrate intact.
Can equipment stay in place during cleaning?
Yes. The dry, non-conductive process allows most equipment to be cleaned in place — including production lines, motors, robotics, switchgear, and turbines — provided proper lockout/tagout and clearance procedures are followed.
What about ventilation and CO₂ safety?
Dry ice sublimates into CO₂ gas. In confined or poorly ventilated spaces we set up mechanical ventilation and use CO₂ monitors to keep concentrations within OSHA permissible limits. Open shop floors generally need no extra ventilation.
Do you provide service nationwide?
Yes. Dry Ice Blasting Of America mobilizes crews and equipment across the 48 contiguous United States for outages, turnarounds, scheduled PMs, and emergency response.
How quickly can you respond to an emergency?
We provide 24/7 emergency response. For most regions a crew can be dispatched the same day or next morning. Call (866) 648-0030 to start a response.
