What is dry ice blasting?

Dry ice blasting (CO₂ blasting) is a non-abrasive, non-conductive industrial cleaning method that uses solid CO₂ pellets accelerated by compressed air. Pellets sublimate on impact, leaving no secondary waste — only the original contaminant for disposal.

Is dry ice blasting safe on electrical equipment?

Yes. CO₂ is a non-conductive dielectric medium, so dry ice blasting is the preferred method for cleaning de-energized switchgear, motors, transformers, MCCs, generators, and bus ducts per NFPA 70E procedures.

Is dry ice blasting food-safe?

Yes. CO₂ is FDA, USDA, and EPA approved for cleaning food contact surfaces. No chemicals, no water, and no abrasive media are introduced.

Does dry ice blasting damage the substrate?

No. Dry ice is non-abrasive and does not erode steel, aluminum, paint, rubber, wood, or concrete when used with correct nozzle and pressure parameters.

How does dry ice blasting compare to sandblasting and pressure washing?

Unlike sandblasting, dry ice leaves no grit residue and does not erode substrates. Unlike pressure washing, dry ice introduces no water — no dry-out time, no rust, no electrical hazard, no contaminated runoff.

What areas does Dry Ice Blasting Of America serve?

All 48 contiguous United States, with planned outage support available to all 50 states. Standard scheduling within 1–2 weeks; emergency outage support within 24–72 hours. Call (866) 648-0030.

How quickly can DIBA mobilize for a power plant outage?

24–72 hours for emergency HRSG and power generation outages. Same-week mobilization for standard scope across the 48 contiguous states.

What is the typical ROI of switching to dry ice blasting?

Most customers see 40–80% reduction in downtime, 25–60% lower cleaning labor, and elimination of secondary waste disposal. Typical payback is 3–12 months with Year 1 ROI of 150–400%.

Dry Ice Blasting for Pharmaceutical and Cleanroom Manufacturing

Pharma cleaning has to be documented, residue-free, and compatible with validated equipment. Dry ice blasting removes product buildup without introducing new chemistry.

In pharmaceutical manufacturing, every cleaning agent you introduce becomes something you have to prove you removed. Dry ice blasting is attractive precisely because the medium disappears: CO₂ sublimates to atmosphere, leaving only the contaminant to be captured.

Applications

Tablet press tooling, punches, and dies
Granulators, blenders, and fluid bed dryer interiors
Coating pan interiors and spray guns
Packaging line change parts and conveyors
Utility equipment, HVAC housings, and dust collection systems
Non-product-contact frames, guarding, and structural surfaces

Why it fits validated environments

No solvent introduced, so no cleaning-agent residue study required for the media itself
No water, so no dry-out and no microbial risk from standing moisture
No abrasive to alter the surface finish of stainless product-contact surfaces
HEPA-filtered vacuum capture keeps removed product out of the room

Documentation to expect

Ask any contractor for a written work instruction covering media source, pressure range, standoff, containment, HEPA filtration, CO₂ monitoring, and post-clean verification method — visual, swab, or rinse as your quality system requires. Cleaning in this environment is a documented activity, not a service call.

Frequently Asked Questions

Is dry ice blasting suitable for product-contact surfaces?+

It is used on product-contact equipment, but acceptance depends on your validation approach and post-clean verification method. Food-grade CO₂ should be specified.

Does it affect stainless surface finish?+

At correct parameters, no. Ra should be verified on a test area if your spec controls it.

Can it be used inside a classified area?+

With containment, HEPA capture, and a room-recovery plan, yes — but the classification impact must be assessed by facility quality staff first.
