LN2 Dosing

No votes yet


Getting Nitro Beer into the can or bottle requires attention and care. The Chart Liquid Nitrogen Doser can ensure the nitrogen levels in your beer are spot on in the can or bottle by adding a quick dose of liquid nitrogen just prior to capping or seaming. Additionally, the LN2 doser can be used to evacuate headspace air in packaged products. Packages and pressures vary but AC Beverage and Chart are experts at LN2 dosing. Let us show you the process we have developed.

The UltraDoser™ is the multi-purpose liquid nitrogen (LN ) dosing system utilizing advanced cryogenic technology and PLC programming.

Chart engineers designed an ultra-efficient system for low to medium production line speeds to dispense a precise dose of LN into every container every time. The LN gasifies and is either trapped in the container to add rigidity or escapes with oxygen to inert the headspace.

• Compact Size – enables installation in limited spaces
• Precise Dosing – delivers consistent, accurate dosing
• Discrete Dosing – up to 2000* containers per minute
• Discrete or Continuous Dosing – change over defined by user
• Vacuum Insulated Technology – the most efficient use of LN
• SoftDose™ Compatible – Chart’s proven technology for hot fill, powder, and granular applications
• RemoteDose™ Capable – remote access and control to increase efficiency and reduce downtime
• MicroDose™ Capable – consistent, accurate dosing over all line speeds
* Results obtained under specific conditions.

How it Works
LN is supplied to the UltraDoser by a vacuum insulated hose and flows into the dosing head. A sensor detects the speed of the line (encoder compatible); a second sensor detects the presence of a container. When a container is detected, the dosing head opens and dispenses an exact amount of pure LN . A PLC (Programmable Logic Controller) is the brains behind integrating the sensors, controls and human interface.

Key Benefits
• Lightweight PET – reduce the weight of PET for cost and environmental savings
• Glass to PET Transition – eliminate glass safety hazards and weight of containers
• Bottle Rigidity – maintain bottle shape even with lighter weight containers
• Eliminate Paneling – increase the internal pressure to offset paneling issues
• Oxygen Reduction – create an inert environment to preserve product freshness
• Extend Shelf Life – minimize oxygen levels
• Ease of Labeling – consistent bottle rigidity creates an efficient labeling process
• Reduce Nitrogen Consumption – measurable and repeatable liquid doses
• Maximize Warehouse Storage Space – increasing product stackability utilizes less square footage
• Stabilize Organic Products – extend shelf life without preservatives
