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 generator 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 generator?
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
- Pressure washing
Drives water into harnesses, bearings, panels and seams, then everything waits to dry. On electrical work it is simply not an option.
- Solvent and degreaser
Good at softening, bad at leaving. There is always a residue and always a drum to get rid of.
- Hand scraping
Slow enough to be uneconomic on a machine, and the tool always leaves a trace.
- Media blasting
Effective and indiscriminate. On soft metal or a finished surface it does damage you then have to fix.
- Dry ice
Thermal contraction cracks the bond between deposit and surface, then the pellet gasses off. Nothing abrasive, nothing wet, nothing left.
What comes off
What dry ice actually removes
The rule of thumb is simple: anything stuck on rather than built in. These are the deposits we see most.
- 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
Sealant squeezed out and cured where it was never supposed to set.
- 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
Taken off in a controlled way when what is underneath matters more than speed.
- Salt and corrosion product
A constant in South Florida. Removing it without stripping the protective finish is the whole trick.
- Ink and printing residue
Ink and coating on anilox and press rollers, surfaces where changing the texture changes the print.
- Food residue
Carbonized product, fat, starch and sugar build-up on processing equipment, cleaned without chemicals touching a food contact surface.
How a job runs
How a job actually runs
Most people have never watched dry ice blasting happen and are not sure what they are agreeing to. Here is the whole sequence, start to finish.
- 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
Pressure and pellet size get dialed in on an inconspicuous spot before we touch anything visible. Painted parts, soft alloys and older finishes all behave differently, and the right setting on one is the wrong setting on another.
- 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
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 it is, what is on it and whether it can stop. If the answer is that dry ice is wrong for it, you get that answer first, not last.
What the job is like to stand next to
Everything the rig needs arrives with it. No tap, no drain, no outlet.
Anything nearby that should not be touched gets masked before we start. That is quicker than explaining it afterward.
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.
