Q: How much dry ice do I need for a project?

The amount of dry ice needed to clean effectively varies from application to application and also can vary dramatically with each dry ice blasting system. The average dry ice consumption for dry ice blasting equipment will range from approximately 0.3 kg per minute for a MicroParticle system to 0.8 kg per minute for a pellet system.

Q: How do I store dry ice and how long does it last?

Dry ice should be stored in an insulated container. The better the quality of the box, the slower it will sublimate. Cold Jet Australia only supplies dry ice in the best quality boxes, that keeps sublimation to just 3-5% per day . Larger gas companies use boxes where the dry ice will be useless in a matter of days.

Q: How much does dry ice cost?

Dry ice costs vary depending on the quantity required and your location. Contact the Cold Jet Australia team to discuss your needs and get a quote.

Q: What do I need to get started with dry ice blasting?

Dry ice blasting requires a simple setup. Along with your dry ice blasting machine, the systems will come complete with both a blast and air hose, an applicator, and a nozzle that is best suited for your application. The only other items needed to operate the system are: Compressed air source (either plant air or an air compressor) Electric power source Dry ice supply An after cooler may be useful if you are using a portable diesel compressor as your air source. An after cooler removes most of the moisture from the system and can cool the air with 5-10°C) of the surrounding air. This is primarily dependent on humidity levels.

Q: What are the benefits of dry ice blasting?

Due to the unique characteristics of dry ice, it has many benefits that make it a more attractive cleaning solution than alternatives. The benefits include: Cleaning equipment in place with little or no disassembly Dry cleaning with no water or chemicals Reducing downtime associated with cleaning Cleaning without secondary waste Improving product quality and reducing scrap Eliminating equipment wear and tear An environmentally responsible cleaning method

Q: How does dry ice blasting work?

There are three primary factors that contribute to the dry ice cleaning process. The factors are Pellet Kinetic Energy, the Thermal Shock Effect, and the Thermal-Kinetic Effect. In order to more easily explain the process, we have created the following acronym (ICE). Impact – Impact of pellets creates a Kinetic Energy Effect. The soft dry ice is accelerated by compressed air through specially designed nozzles at supersonic speeds. Cold – Cold temperature of dry ice pellets creates a Thermal Effect. The temperature of dry ice (-109°F / -78.9°C) causes the contaminant to embrittle. This helps break the bond between the substrate and the contaminant. Expansion – Expansion of the dry ice pellets. Dry ice pellets sublimate upon impact, volumetrically expanding in size, removing the contaminant.
