Improve shelf life
Preserve taste, color and freshness
INERTING EXAMPLES
Vegetable oils
Dairy products
Wine
Fruit juices
Energy drinks
Snacks
Vegetables
Sauces
Powders and solids
Vitamins
Health drinks

NITROGENATE
Using liquid nitrogen dosing technology, a craft brewer can precisely dose non-widget cans to achieve similar results as with a widget. The agitation necessary to create the creamy head can be caused by a rigorous pouring, or to a lesser degree, by using glassware that has been laser-etched.
NITRO-INFUSED
DRINKS
Gaining momentum from the success of nitro-beer, nitro-infused drinks re-imagine familiar drinks such as coffee, tea, chocolate milk, energy drinks and cocktails to create rich, creamy, visually intriguing drinks. Dosing just a drop of liquid nitrogen creates an enhanced mouthfeel and enrichment to the flavor.
Nitrogenate with or without widget

Nitrodose® G2 Pro Linerter III
CUSTOMIZE YOUR LIQUID NITROGEN DOSING SYSTEM
When access to the filling line proves difficult, we offer alternative layouts to the standard dimensions – positioning the dosing head in the ideal location. For easy installation adjustable supports are available in various designs
MULTI-HEADS
For filling lines that require simultaneous dosing into multiple packages Vacuum Barrier’s multi-head dosers are the perfect solution. Dosing heads are installed side by side and each package is dosed simultaneously and with the greatest consistency.
ASEPTIC SYSTEMS
Vacuum Barrier dosers adapt to operate in clean room environments and integrated into ultra clean bottling lines. Various units and solutions are available depending on the design of the filling line.
3-D TECHNOLOGY
Precise discrete dosing of liquid nitrogen using direction dose dispersion eliminates splashing to improve accuracy. This advancement can be used for lightweight PET packages or hotfill beverages in PET or lightweight aluminum cans.
AUTOMATIC CIP PROTECTION
Vacuum Barrier’s automatic nozzle protection prevents moisture from entering the dosing head to eliminate potential freeze ups. Withstands high pressure wash down or aggressive chemical cleanup and provides immediate nozzle closure after dosing stops.
REMOTE ACCESS CONTROL PANEL
Provides Vacuum Barrier certified technicians with the ability to remotely access control panels to troubleshoot and assist with any setting modifications. This option is available on most Nitrodose touchscreen systems.
LIQUID NITROGEN PIPING SYSTEMS
Vacuum Barrier offers dynamic or vacuum-sealed SEMIFLEX® piping in either OHFC copper or stainless steel, both providing the lowest cool down and steady state heat loss of any liquid nitrogen piping system.
SEALED VERSUS DYNAMIC VACUUM
Dynamic systems include a vacuum pump that continuously maintains and improves the vacuum insulation. Sealed systems do not include a vacuum pump, since the vacuum is created during manufacturing and is permanently sealed with each component.
SEMIFLEX® systems deliver liquid nitrogen at bulk tank pressure in two-phase condition. This basic system is used in applications that simply require transfer of liquid nitrogen.
SEMIFLEX® systems with a vapor vent employ a mechanical float operated device that minimizes two-phase flow – maintaining the liquid nitrogen in SEMIFLEX® at storage pressure. This system is used in applications where the piping system is required to be cold and ready for immediate use.
SEMIFLEX®/Triax/Liquid Vapor Phase Separator systems deliver liquid nitrogen in pure liquid form at atmospheric pressure. The addition of the Triax pipe and Liquid Vapor separator eliminates twophase flow delivering sub-cooled liquid nitrogen by gravity to each use point. By separating the vapor and venting it prior to liquid delivery, no gaseous nitrogen passes through your equipment. This system is used in applications where singlephase liquid is critical to the production process.
COBRAFLEX® sealed vacuum liquid nitrogen hoses are available in stainless steel with a highly flexible outer wrap. Combined with SEMIFLEX®, efficient plant piping, connections are easily made to use points.
