Power Distribution Equipment Ice Blasting
When people call about power distribution equipment, the constraint is usually the same. 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 power distribution 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 power distribution 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
The other ways to do this
- Media blasting
It works by removing material, which is the problem. Acceptable on heavy steel, damaging on soft alloy, plating or a machined surface.
- Pressure washing
The water has to go somewhere, and on most equipment that somewhere is inside it.
- Solvent and degreaser
Chemistry works, but you inherit ventilation, waste handling and a film on the surface.
- Hand scraping
Slow, inconsistent, and the tool marks the surface. Fine for a small area, unworkable across a machine.
- Dry ice
The deposit shrinks away from the surface it is stuck to and releases. The ice is gone before it can do any harm.
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.
- Paint and coatings
Selective removal, layer by layer, on parts where media blasting would cut into the substrate.
- 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
Carbonized product build-up in a plant where neither standing water nor a chemical film is acceptable.
- Grease and oil
The greasy base coat that traps grit and dust. It releases early and takes the loose material with it.
- Carbon and soot
Baked carbon on a manifold, oven or weld fixture. Thermal shock is exactly the wrong thing for the bond holding it on, which is why this works.
- Adhesive and sealant
Bonded material that outlived whatever it was bonding, usually harder to shift than the part it is on.
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.
- You describe the job
The machine, the deposit and the downtime you can afford. Those three things decide the whole job, and we would rather know all of them before quoting.
- We look at access and containment
Siting the compressor, masking what must not be touched, and catching what comes off, settled before the first pellet.
- 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 on impact. What is on the floor afterward came off your machine, and clearing it is ours to do.
- You look before we pack up
We would rather you find the missed spot while we are standing there than a week later. Another pass on the day is the cheapest fix available.
What to expect on site
Solid carbon dioxide leaves no residue at all. What it does do is displace air, so an enclosed space gets ventilated as part of the job rather than as a precaution added later.
Expect noise. Everybody inside the working area wears hearing protection, us included.
Cold surfaces are the one aftereffect. Depending on the piece that is either a few minutes of patience or some condensation while it returns to room temperature.
Air comes from our own compressor. You do not need to provide power, water or a connection of any kind.
Describe what you are dealing with.
Send the equipment, the location and a short description. Photos help. You will hear back from Giancarlo or Kenny, not a call center.
