What builds up, and why it matters
On this kind of work the problem is fine dust and particulate loading on switchgear, busway, fans and mechanical plant. A data hall cannot take water and cannot take downtime. Cleaning has to be dry, contained, and finished inside the window you were given.
Work is planned around the maintenance window and the containment the facility requires. The people who call us about data center fan are usually critical facility and data center operations teams, and the thing they are actually worried about is particulate migrating somewhere it should not, or a window overrunning.
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 data center fan?
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
How this compares to the usual methods
- Solvent and degreaser
Softens the contaminant but leaves a film, fumes and a disposal problem, and attacks finishes you meant to keep.
- Hand scraping
Slow, inconsistent, and the tool marks the surface. Fine for a small area, unworkable across a machine.
- Media blasting
Abrasive by definition. Anything with a tolerance or a finish worth keeping comes out changed.
- Pressure washing
Pressure pushes moisture past seals and into connectors, and then you wait. Panels and motors rule it out.
- Dry ice
Thermal shock breaks the bond. The pellet sublimates, so nothing abrasive touches the part and nothing is left to collect but the contaminant.
What comes off
What this takes off
The method does not care much what the contaminant is, only that it sits on top of something. Here is the usual list.
- Ink and printing residue
Dried ink on precision roller faces, cleaned without altering the cell structure that does the work.
- Food residue
Carbonized product build-up in a plant where neither standing water nor a chemical film is acceptable.
- Grease and oil
The soft film that holds dust and swarf against metal. It is what makes a part feel dirty long after it looks clean, and it comes off first.
- 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.
- Resin and mold release
Release agent and resin build-up on tooling, where a solvent fix trades one residue for another.
- Paint and coatings
Removed selectively where the substrate underneath has to survive, which rules out most abrasive approaches.
How a job runs
The sequence, start to finish
There is no mystery to how these jobs run, and no part of it we would rather you did not ask about.
- 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 media disappears on contact; the contaminant does not. Gathering what came off is included, not a line added afterward.
- You look before we pack up
If something needs another pass we do it then, on site, while the rig is still running. That is a better outcome for everyone than a callback.
- You describe the job
Tell us the machine, the mess and the constraint. A couple of photos answers more than a long description, and if the honest answer is that something else suits it better, we say so.
Before we turn the rig on
Masking happens first. Whatever is adjacent and vulnerable gets covered before the hose is picked up.
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.
This is not a quiet method. Ear defenders are standard issue on site for anyone nearby.
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.
Describe what you are dealing with.
Give us the job, the address and a rough description, pictures if you have them. The call back comes from Giancarlo or Kenny directly.
