ISO/UN Air Storage

storage-un

 

 

 

 

All UN cylinders are shipped with a protective cap for the cylinder valve. Valve caps are shipped installed on loose cylinders and shipped loose with racked assemblies. The mandatory retest period for UN cylinders is every ten (10) years. Under no circumstances are these cylinders to be filled to a pressure exceeding the marked service pressure at 70° F.

BULK AIR STORAGE

 

 

Bulk storage for limiting the number of compressors starts to 4 times per hour can be calculated by the following formula:

VR = 58 x (QC / ΔP)

  • VR = Volume of storage, cubic feet water volume
  • QC = Capacity of the compressor, standard cubic feet per minute (scfm)
  • ΔP = Approximate dead band of the final pressure switch, pounds per square inch (psig)

Multiple cylinders can be used for applications that require a large volume of storage.

Contact BAUER for sizing storage with multiple banks for cascading.

TECHNICAL DATA FOR GASES AT PRESSURE

The table below list the volume of different gases that can be compressed into one (1) cubic foot water volume at the given pressure. The information is based on 70° F and accounts for the compressibility of the gas. The table can be used to calculate the volume of air or gas that can be stored in a cylinder of known water volume. Likewise, the water volume of a cylinder can be calculated if the capacity of air or gas stored in the cylinder is known.
