Praxair is the largest industrial gas supplier in North America with over $10.8 billion in worldwide sales. Their food laboratory allows customers to test food production using Praxair equipment. A cost analysis showed their nitrogen freeze tunnels increase capacity by 20% and have 84% lower initial costs and 92% lower maintenance costs than mechanical freezers, paying for themselves in savings within 5 years. The freeze tunnels also reduce dehydration, are easy to clean, and require less space with lower capital costs and nitrogen supply savings due to Praxair's size.
