How to Determine Your On-site Cryogenic Liquid Storage Capacity
For hydril tubes, tube trailers and cylinder packs, please reference your contract to determine your on-site storage capacity. For standard cryogenic tank storage capacity, you can also reference your contract—or you can estimate your capacity through our APDirect® customer portal by following these steps:
- Log into the MyAirProducts customer portal.
- Click on “Inventory Management” on the left.
- Enter your Account Number (Ship-To) for the tank you would like to find the capacity for and click “Search”.
- Scroll down to the “description” column.
- The first part of the description lists the product (Ar = Argon, CO = Carbon Monoxide, He = Helium, H2 = Hydrogen, N2 = Nitrogen, O2 = Oxygen).
- The second part of the description lists the capacity.
- If there is an ‘M’ or ‘X’ after the first numerical value listed, multiply the value by 10 to obtain gallons.
- If there is an ‘MM’ or ‘XX’ after the first numerical value, multiply the value by 10000 to obtain gallons.
- If there is an ‘L’ after the first numerical value, this means you have a Microbulk tank, and capacity is the numerical value listed before the ‘L,’ expressed in liters. Do not multiply the value by another number. Simply move to step 5.
- Convert Gallons to Pounds or Liters to Pounds using our interactive conversion tool. See the following examples:
- Description = N2 600M-250-102. This is a nitrogen tank with a capacity of 6000 gallons, which converts to 40482.607 pounds.
- Description = O2 1.1MM-250-698. This means the tank is used for Oxygen, and the capacity is 11000 gallons, which converts to 104763.9 pounds.
- Description = Ar 1500L-350-A127. This means the tank is used for Argon, and the capacity is 1500 liters, which converts to 4607.981 pounds.
