CryoTree Sub-Assembly

Rockwood Swendeman's CryoTree® assemblies are manufactured for use on stationary cryogenic storage tanks to isolate safety relief valves and rupture discs in the event they need to be serviced. Utilizing this system eliminates the need to shut down and evacuate the tank for service. Rockwood Swendeman's CryoTree® assembly includes high capacity safety relief valves, full flow diverting valve, rupture discs, bleed valves, and related piping assembled, oxygen cleaned in conformance to CGA G-4.1, hydrostatically tested as a complete unit to assure leak tightness. This modular assembly provides for just a single connection to the internal tank piping.

Air Liquide America, Houston, Texas, has standardized on the Rockwood Swendeman CryoTree® assembly as part of their ongoing cost reduction programs to serve their customers more effectively.

Air Liquide has stated that although the total cost of the Rockwood Swendeman CryoTree® parallels their internal fabricated design used in the past, their fabrication time can now be spent in other areas. Originally five to six separate purchase orders were issued for individual components. It now requires only one. This modular design provides only two part numbers for their complete tank inventory providing standardization on a global basis.
