Vacuum Insulated Filter

The Vacuum Insulated Filter, namely Vacuum Jacketed Filter, is used to filter impurities and possible ice residue from liquid nitrogen storage tanks.

The VI Filter can effectively prevent the damage caused by impurities and ice residue to the terminal equipment, and improve the service life of the terminal equipment. In particular, it is strongly recommend for high value terminal equipment.

The VI Filter is installed in front of main line of VI pipeline. In the manufacturing plant, the VI Filter and VI Pipe or Hose are prefabricated into one pipeline, and there is no need for installation and insulated treatment on site.

The reason why the ice slag appears in the storage tank and vacuum jacketed piping is that when the cryogenic liquid is filled at the first time, the air in the storage tanks or VJ piping is not exhausted in advance, and the moisture in the air freezes when it gets cryogenic liquid. Therefore, it is highly recommended to purge the VJ piping for the first time or for the recovery of the VJ piping when it is injected with cryogenic liquid. Purge can also effectively remove the impurities deposited inside the pipeline. However, installing a vacuum insulated filter is a better option and double safe measure.
