Dry ice is the solid form of carbon dioxide (CO2). In order to create dry ice, CO2 gas is pressurised and cooled to form liquid CO2 (LCO2) and is then injected into a pelletizer, or dry ice production unit. Within the pelletizer, the pressurised LCO2 is released to atmospheric pressure, which causes it to solidify into a snow-like consistency. This is then compressed into pellets, blocks, or slabs.

Q: Should I make my own dry ice?

In the right situation, making your own dry ice can save you a lot of time and money while eliminating headaches. Producing your own dry ice can give you greater control over your production, processing, and cold chain management systems, while also reducing waste and cutting operational costs. By answering a few simple questions, you can determine whether producing your own dry ice is right for you. Those questions include: How much dry ice do you consume weekly/monthly? What are your current delivery costs? Is dry ice a part of a critical path in your operation? Do you waste a lot of dry ice per week? Does your facility have a CO 2 tank and three-phase power?

Q: Can I make my own dry ice?

Dry ice can be produced on demand using a dry ice production machine (pelletizer or slice maker). Producing your own dry ice must be economically viable and the amount of dry ice used on a daily and weekly basis must be considered. Pelletizers, slice makers, and reformers can be equipped with multiple dies to produce a range of extrusion sizes (3mm to 19mm) and final product size. Dry ice production equipment can produce, dose, and package multiple sizes of dry ice for a broad range of solutions.

Q: Will I receive help when installing my machine?

Our dry ice blasting units are simple to setup and use, but for more complex installations we are there to help. Our local team, based in Sydney and Melbourne, is available to help in the installation of your dry ice production unit.

Q: How do I receive training?

We offer a range of training services that can be performed at your facility or at one of our offices in Sydney or Melbourne. Our team will instruct employees on how to operate your machine more efficiently and discover how to take full advantage of all the technologies available to them. Learn more about training >

Q: Where can I buy parts and accessories?

You can purchase spare parts and accessories from Cold Jet Australia. Learn more about our parts and accessories >

Q: Does dry ice blasting leave a residue?

Dry ice blasting does not leave residue or waste. Dry ice sublimates upon impact with the surface being cleaned, which results in no secondary waste, no residue and no introduction of moisture. This eliminates extra cleanup, disposal of secondary waste streams and additional cleaning preparation, such as masking delicate sensors or wrapping electronic components before cleaning. This significantly reduces the duration of cleaning projects and the resulting shutdowns. Elimination of secondary waste also allows equipment to be cleaned while online and still operating.

Q: Can dry ice blasting kill mould?

Dry ice blasting removes 99.9% of mould spores faster than traditional cleaning methods when IAQA standards are followed. The process eliminates timely manual cleaning and does not create secondary waste, which reduces mould remediation time and reduces total labor costs and project time. The dry ice blasting process does not utilise chemicals and has the ability to deodourise affected areas.
