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: Where can I buy parts and accessories?

You can purchase spare parts and accessories from Cold Jet Australia.

Q: Are there safety precautions with dry ice production?

When working with CO2, precaution must always be taken to ensure that the area is sufficiently ventilated and that proper PPE is administered when dealing with the liquid or solid form of CO2 (dry ice).

Q: How much does a dry ice production machine cost?

We have a number of different machine options depending on your production needs. Contact a local Cold Jet Australia representative to find out what the best machine will be for you. Contact us >

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: What types of infrastructure do I need for a dry ice production machine?

You need a liquid CO2 tank, three phase power, exhaust capability, supply and support lines, and adequate floor space for both the dry ice production machine and dry ice storage. If you do not have a liquid CO2 supply already in place, Cold Jet can perform a site visit to help determine what you would need to do and what your investment and payback would be. Cold Jet can then arrange for the installation and leasing, if required, to be completed through our trusted affiliates. Contact us to discuss your dry ice production options >

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 >
