So, no matter what your dry ice volume — from a 50-pound block, to tons per year — Praxair can be your one-source supplier for all your needs. The facts about Dry Ice Dry ice is solidified carbon dioxide (CO2). Distinct from regular water ice, which exists at temperatures of 32°F (0°C) and below, dry ice is extremely cold, -109°F (-79°C). Unlike water ice, dry ice does not melt. Instead, it sublimates (changes directly from solid to gas), releasing CO2. Carbon dioxide vapor is substantially heavier than air. In confined, poorly ventilated spaces it can displace air, causing asphyxiation. It is even possible for CO2 vapor to accumulate in low-lying areas, out-of-doors, under zero or very light wind conditions. | ||||||
