If supplying gas generated from liquid nitrogen
Take adequate precautions with pipe resistance and other factors as sufficient secondary pressure cannot
be obtained when using nitrogen gas generated from liquid nitrogen. Prepare a PTFE pipe with an outer

For details, refer the Pre-Installation Requirement of nitrogen generator. Various other models are
available.
