What is Dry Ice?

Dry Ice is made of Food Grade Liquid CO2= Totally Free of Water


Liquid CO2 at -20°C is injected into a production cylinder through a spray nozzle with a pressure of 14 - 17bar (200-290 psi), where it expands at atmospheric pressure into CO2 snow. This snow is then compacted by rod & piston action into solid CO2 = Dry Ice. Different types of Dry Ice machines produce various forms of Dry Ice. The common forms of dry ice are:

1 Blocks 10-20kg p/block
2 Nuggets round shaped/10-16mm diameter / 15-30mm in length
3 Pellets round shaped/2.5-3.5mm / 3-8mm in length
 

Dry Ice as an industrial product has been around for approximately 80 years and is mainly a consumable in the food production and transport industries. However, since its invention many other uses have been found, including a more recent technology, Dry Ice Blasting.
