Products / Technology
- LN2 Dosing
- Design, engineering and manufacturing of liquid nitrogen dosing systems to pressurize thin-wall packages, or displace oxygen to extend product shelf life.
A precise droplet of liquid nitrogen dispensed into the package, vaporizes and expands to fill the headspace forcing nitrogen into the solution and pressurizing the bottle. To inert the headspace the vapor is allowed to expand, prior to sealing, pushing out oxygen and extending shelf life.
- LN2 Piping
- Vacuum jacketed dynamic and sealed SEMIFLEX LN2 pipe delivers LN2 at bulk tank pressure in two-phase condition for on-demand supply.
The liquid/vapor phase separators deliver low pressure LN2 to each use point for on-demand supply. Combined with SEMIFLEX Triax LN2 pipe eliminates two-phase flow to all use points.
