Frequently Asked Questions

How does dry ice blasting work?

Dry ice is frozen carbon dioxide, which at -109 F, cleans with three types of action:  First is the impact of the ice pellets on the surface being cleaned, usually at between 60-110 psi, but can be at a lower psi or up to 200+ psi.  Secondly, upon impact the frozen gas converts, or sublimates, into a gas, releasing energy that creates an explosive effect that is a force multiplier in generating cleaning action.  Finally, the extreme cold striking a warmer surface, causes a thermal shock effect shrinking the surface being cleaned and loosening the debris from the underlying substrate.


What Personal Protective Equipment do I need to dry ice blast?

We recommend at the minimum to wear sturdy temperature proof gloves, quality ear protection (usually the can style over the ear type), safety glasses, goggles and/or a face shield.  Anyone nearby should wear ear protection and eye protection to protect themselves from flying debris.


Are there hourly limits for a weekly rental of a dry ice blasting machine?

Yes, rentals are for 8 hours of blasting per day, or 40 hours per week.  Usually this is plenty of time to finish most cleaning projects.


Does using more blasting dry ice per minute increase cleaning speed?

As a general rule, the amount of dry ice used per minute does not increase speed.


Will dry ice blasting damage my application?

With the correct equipment and settings, dry ice blasting is completely non-abrasive. Care needs to be taken to make sure you don’t blast anything that is inherently fragile or susceptible to very cold or high air pressure conditions.  Several things that can be damages are lightweight plastic fittings, small wires, plastic sensors and similar items.


Does dry ice blasting change the temperature of what I am blasting?

Yes, it usually does.  Some changes are dramatic, some are slight, usually based upon the size and density of the substrate being blasted, but the change in temperature is usually very temporary and returns to normal temperature quite quickly.


What advantages does dry ice blasting have over traditional blasting media?

Because dry ice returns to a carbonic dioxide gas after impacting the surface, the only cleanup you have to perform is to clean up whatever has been removed from the object(s) being blasted.  Additionally dry ice blasting is dry, not abrasive, and non-toxic.


How do I get training on how to use the dry ice blasting equipment?

Call Dry Ice Gear today, we offer tele-training, on-site training and a range of internet videos to train people in how to operate our equipment.


How do we use dry ice blasting equipment safely?

Never point the nozzle at anyone or yourself, and treat it carefully when it is under power as it can kick back and ricochet debris or dry ice into your body.  Use dry ice only in a well ventilated space. At coler than 100 degrees Fahrenheit, it will damage skin on contact, so protect yourself from that possibility.


Should the hopper lid be open or closed while I dry ice blast?

Keep the hopper lid closed while dry ice blasting. This will keep foreign objects from falling into the hopper and damaging the mechanisms that feed the blasting dry ice into the blast hose. It will also keep the blasting dry ice from clumping, ensuring a better dry ice blasting experience.
