Liquid Nitrogen Dosing System

[St Rippy]

I was wondering if anybody and I mean anybody out there has used a Linerter Liquid Nitrogen Dosing system to prepurge bottles? Does it slow down the speed of the line? Does it really work to reduce O2 pickup? What are the economic impacts? Any information would be greatly appreciated!!

Cheers

They are great! Never slowed down the line, never broke down, just have to change the tank out every now and then...and oh yeah, liquid n2 is a bit pricey. Linerters do a great job of purging headspace and removing traces of o2.
