CRYOBOX CRYOBOX ISOTANK

▪ The techology adopted employs Isotanks to store LNG, providing greater reliability and flexibility to the operation, maintenance, and possible expansion of the tank farm.

▪ The use of Isotanks also dramatically lowers the load over the ground, which ISOTANK results in smaller civil foundations and consequently, their cost.

▪ The modular approach allows for a much more efficient and lower cost logistics system, since this is standard size for transportation (40’ container).

▪ Installation of these modules on-site is plug-and-play, and does away with large-scale machinery and specialized labor, which makes it possible to install them at a lower cost and reduced time frame.
