KTW NovoDoser

The Ultimate Solution for Preserving, Pressurizing and Freezing Your Products

Discover the ideal solution to ensure the safety and stability of your products during transport after filling, while improving their shelf-life and appearance. Our LN2 dosing technology has been successfully used in 1000+ applications by hundreds of customers worldwide.

Brand-new packaging concept

The food and beverage industry faces challenges in maintaining product quality and freshness during transportation and storage. Oxidation is a major issue that can lead to spoilage and reduced shelf-life. To combat this, headspace inerting is used to displace oxygen inside the package with an inert gas (nitrogen).

Traditional methods of dosing inert gas are mostly slow, inaccurate, energy-intensive, and prone to errors. This results in inconsistent and inadequate filling, which can lead to quality variations, spoiled products, and consequently lost revenue.

In this context, dosing liquid nitrogen (LN2) has proven to be an ideal solution, especially for products that are sensitive to oxidation and/or contain thin-walled packaging material.

"Our dosing technology enables exceptional accuracy and control over the dosing process. It ensures that you can achieve the desired preservation, pressure equalization, or freezing effect, regardless of how complex your application is."

Why use LN2 Dosing System?

Container Pressurization

Liquid Nitrogen Dosing enhances product packaging quality, provides significant cost savings. Through container pressurization and subsequent rigidity improvements, packaging material can be reduced. Thus, allowing cost reductions in packaging material and ecological carbon footprint.

Why use LN2 Dosing System?


LN2 dosing is the most effective process for inerting food & beverage containers to achieve desired oxygen exclusion. Delicate products filled into bottles/cans/jars should have very little contact with oxygen for the following reasons:

How does it work?

Novo Doser

LN2 is supplied to the doser by a vacuum-insulated pipe and flows into the dosing head. Sensor will detect the container and send pulses to the controller. Controller will command the dosing head to dispense the required amount of LN2 into the container. LN2 droplets quickly evaporate and expand 700X into gaseous N2 equivalent, filling the container headspace with inert N2 gas at the desired pressure.
