Electrical Room Equipment Ice Blasting
Electrical Room Equipment comes to us when the usual cleaning methods are too harsh for the part. We clean it without water, without chemicals and without anything abrasive touching the surface.
What builds up, and why it matters
On this kind of work the problem is conductive dust, carbon tracking, oil mist and contamination on insulators and bus. This is the work that makes the low-moisture part of the process matter. You cannot wash a panel. You cannot blast grit into a motor. Dry ice leaves no standing water in a harness, a winding or a cabinet.
Equipment is de-energized and the area ventilated before anything starts. The people who call us about electrical room equipment are usually facility electricians and reliability engineers, and the thing they are actually worried about is a flashover, or moisture left where moisture should never be.
The method
Why dry ice and not the alternatives
- Non-abrasive
The pellet is soft and sublimates on impact, so the work is thermal rather than mechanical. Machined faces, plating, paint and gaskets survive it.
- Low moisture
No standing water in a harness, a bearing or a cabinet, and no dry time before the equipment goes back into service.
- No secondary waste
Sand, soda and walnut shell all have to be swept and hauled. Dry ice leaves only the contaminant it removed.
- Often no teardown
Much of this work is done in place, which is usually where the real saving is. The labor is in the disassembly, not the cleaning.

Questions we get asked first
Will it damage the surface underneath?
On most substrates, no. The pellet is soft and sublimates on impact, so it does thermal work rather than mechanical work. We still test an inconspicuous spot first on anything unusual.
Do you have to take the equipment apart for electrical room equipment?
Usually far less than you would expect, and often not at all. Cleaning in place is where most of the saving comes from, because the labor is normally in the teardown and reassembly.
How much mess does it make?
Far less than the alternatives, because the blasting media disappears. What is left is the contaminant itself, which we contain and clean up.
Do you come to us?
Yes. The whole rig is mobile. Compressor, hose and operator arrive at your shop, plant, driveway or dock, anywhere across South Florida from Miami out to roughly a hundred miles.
What does a job cost?
It depends on the equipment, the contaminant and the access, so we will not throw a number at you over the phone without understanding the work. Describe the job and we will give you a real figure.
How soon can you look at it?
Send photos and a short description and one of the owners gets back to you. If you have a shutdown or a deadline, say so up front and we will tell you honestly whether we can hit it.
The comparison
Why not just pressure wash it
- Pressure washing
It is fast and it is wet, which is fine outdoors and unusable on anything with a winding in it.
- Solvent and degreaser
Good at softening, bad at leaving. There is always a residue and always a drum to get rid of.
- Hand scraping
Fine on a patch, hopeless on a machine, and the blade leaves its own evidence.
- Media blasting
It works by removing material, which is the problem. Acceptable on heavy steel, damaging on soft alloy, plating or a machined surface.
- Dry ice
The pellet is soft and the mechanism is temperature, not abrasion. It turns to gas on impact, so the only thing left to sweep up is what came off.
What comes off
What comes off, and why
If it is bonded to the surface rather than part of it, there is a good chance this takes it off. The list below covers most of what we are called out for.
- Carbon and soot
The hard black crust on a housing, an oven or a weld cell. Bonded by heat, and the first thing to release under thermal shock.
- Adhesive and sealant
Bonded material that outlived whatever it was bonding, usually harder to shift than the part it is on.
- Resin and mold release
Production residue cured onto tooling. Solvent softens it and leaves its own film; the ice lifts it and takes nothing with it.
- Paint and coatings
Removed selectively where the substrate underneath has to survive, which rules out most abrasive approaches.
- Salt and corrosion product
Salt deposit and the oxidation it starts. Anything abrasive removes the protection along with the salt.
- Ink and printing residue
Dried ink and coating build-up on rollers and press components, where the surface texture is the product.
- Food residue
Burnt-on product, fat and sugar on processing gear, with no chemical residue left on a contact surface.
How a job runs
Nothing about this should be a surprise
Nobody should have to guess what they booked. This is every stage of a job in the order it happens.
- We look at access and containment
Access drives the plan: reach, siting, masking, and the route the removed material takes off the job. It is the part customers think about least and we think about most.
- We test a small area
Settings get proven somewhere nobody looks before they get used somewhere everybody does. What is correct on cast iron will mark aluminum, so the test is not a formality.
- We blast, then clean up
The ice is gone the moment it does its work. What stays behind is the grease or carbon that came off, and collecting that is part of the job, not an extra.
- You look before we pack up
Inspect it with the rig still set up. Anything you are not happy with gets another go before we leave.
- You describe the job
What the equipment is, what is on it, where it lives, and whether it can be shut down. Photos tell us more than a paragraph. If dry ice is the wrong tool we say so on that call rather than after taking your money.
What to expect on site
The media is solid CO2, nothing toxic and nothing left behind, but it pushes oxygen out of a closed room. Ventilation gets planned before the hose is connected.
Expect noise. Everybody inside the working area wears hearing protection, us included.
Surfaces come out cold. On some jobs that means waiting a few minutes before handling, and on others it means condensation as the part returns to ambient temperature.
Everything the rig needs arrives with it. No tap, no drain, no outlet.
Tell us what needs cleaning.
Tell us what the machine is, where it is and what is on it. A photo or two speeds it up. One of the owners calls you back.
