Dry Ice Theory

A safe alternative for you and the environment

Dry Ice Blasting: An Alternative to Traditional Cleaning Methods. Traditional cleaning methods can leave you with various problems ranging from the creation of secondary waste to not completely cleaning the surface.
Dry ice blasting is an alternative to traditional cleaning methods, such as Abrasive Blasting (glass, walnut shells, silicone), Sandblasting, Soda Blasting, Pressure Washing, Chemicals, and Hand Tools.

Dry ice blasting offers various benefits to all of the above cleaning methods. Dry ice blasting uses dry ice pellets, or MicroParticles, consisting of recycled carbon dioxide, with compressed air to blast materials off of surfaces and to provide a clean surface without causing damage.

Dry ice cleaning is effective and safe

- Dry ice is an approved medium by the EPA, FDA and USDA as an acceptable material in cleaning methods.
- For Food processors, dry ice cleaning have been documented by the Food Standards Agency to effectively decontaminate surfaces of Salmonella, E.coli and Listeria.

- Dry Ice Cleaning does not release harmful gases into the atmosphere.

- Dry ice does not produce CO₂ or add CO₂ to the atmosphere and therefore does not contribute to the greenhouse effect.

- Dry ice cleaning does not generate secondary waste

- Dry ice cleaning is safe and non-toxic (once pellets impact the surface, they dissipate).

- Dry ice cleaning reduce or eliminates employee exposure to (and corporate liability from) the use of dangerous chemical cleaning agents.

Environmentally Responsible

In addition to being clean and safe, it is also important to remember that dry ice is obtained as a byproduct of other industrial processes - i.e. it is made from reclaimed CO₂. It does not produce CO₂ or add CO₂ to the atmosphere and therefore does not contribute to the greenhouse effect. Dry ice cleaning is truly and completely environmentally responsible.

Other cleaning methods can be toxic

- When using solid grit media or water for cleaning hazardous materials, the cleaning media also becomes hazardous, requiring special handling, disposal and regulatory reporting. Dry ice creates none of these waste stream additions
- Sand, soda or water blasting can create downstream contamination that affects surrounding vegetation.
- Chemical and solvent cleaning methods are toxic, which creates toxic waste and requires disposal.
- Workers are exposed to potentially harmful substances through the use of chemicals and solvents.

What is Dry Ice Cleaning?

Environmentally responsible cleaning and surface preparation

How does it clean?

Dry ice cleaning uses solid CO2, a non-abrasive media that won't damage surfaces or equipment. The super cooled dry ice pellets or particles are accelerated at supersonic speeds and sublimate on impact, resulting in the surface being cleaned, lifting dirt and contaminants off the underlying substrate.

How it works...

Instead of abrasive media to grind surfaces (and damage them), SPECCo2 uses dry ice (Solid CO2) accelerated at supersonic speeds that sublimate upon impact and lift contaminants from substrates.

Dry Ice: MicroParticles

Less Air. Less Ice. More Coverage

Dry ice cleaning is effective and safe

SPECCo2's patented, shaved dry ice MicroParticle technology provides the most thorough clean for many applications. By shaving dry ice media into the finest MicroParticles, more particles enter the air stream and strike the surface per second than a traditional methods, quickly removing the contaminant and providing the fastest clean. The sugar-sized, shaved MicroParticles will enter the hardest-to-reach places and are small and delicate enough to pass through sensitive materials (like vents) for a thorough clean without worry of damaging the surface.

Managing consumables is important when incorporating dry ice cleaning and shaved MicroParticles will save you time and money. Due to the particle size, less compressed air is needed to propel the shavedMicroParticles to peak velocities, resulting in a much quieter clean. In addition, the improved particles coverage and particles strikes per square inch when shaving reduces the amount of dry ice required for cleaning.


Because the surface is hit by more MicroParticles at a time, it is cleaned faster and more evenly.


When compared to pellets or fragmented pellets, MicroParticles produce less noise, resulting in a better working environment.


MicroParticles minimize the risk of damage to surface, vents, ducts, bridges, high gloss polished forms or ejectors.


Due to size MicroParticles are able to reachayeas where pellets and conventional methods can not.


Less power and kinetic energy are needed to accelerate MicroParticles, significantly reducing dry ice and compressed air consumption.

Dry Ice Manufacturing & Supply

Leading experts in the industrial oxygen gas industry

SOVIGAZ was established in 1974 based on the merger between Vietnam SOAEO Division and Vietnam Steam Industry Company. As a leading state-owned enterprise in the production of medical gases, industrial gases, medical gases, electric welding rods and chemicals in Vietnam.

SPECCO2 was very pleased to be able to supply Sovigaz company with a PR120H dry ice production machine from SPECCo2 based on the need to preserve and sell dry ice. With fully automatic technology in just one button operation and quick start-up within 5 minutes, On-site dry ice production has become so much easier with Sovigaz company. Besides, The PR120H can produce 120kg (265lbs) an hour of high quality dry ice pellets with lowest liquid CO2 inlet that completely meets the requirements of the company Sovigaz while still ensuring highest quality dry ice pellets.

By Applications

We've been able to cut back on our use of chemical solvents. We use about 25% of what we used to, which makes us a much more environmentally responsible company

Matt Schrift Engineer Robotworx

It's better for the people and for the environment. This technology has shaved time and allowed us to reduce our use of chemicals.

Bob Hawkey Vers-Trim

Using dry ice cleaning reduces harmful air emission and generally creates no addition to the volume of the cleaning process waste stream...in-process machinery can be cleaned on-line, resulting in decreased labor cost and less down-time.
