Used Nitrogen Dosers available from M&E are used to dispense a precise dose of liquid nitrogen (LN₂) into bottles, cans, jars, and other containers immediately before sealing. Also known as liquid nitrogen dosing systems, these machines help displace oxygen, extend product shelf life, increase container rigidity, reduce package paneling, and support lightweight packaging designs. Nitrogen dosers are widely used in the beverage, food, pharmaceutical, and household products industries for packaging water, juices, teas, edible oils, sauces, coffee, beer, wine, and other products requiring headspace inerting or pressurization. Available equipment may include inline liquid nitrogen dosers, cryogenic dosing systems, and complete LN₂ dosing packages. Our inventory may feature equipment from leading manufacturers such as Chart, Vacuum Barrier Corporation (VBC), HSN Technologies, and other recognized packaging equipment suppliers. Contact M&E to review current availability or to source a used nitrogen doser that meets your container size, production speed, and packaging requirements.
