UltraDoser

Product catalog summary

Introduction
Chart Inc. is renowned for its frost-free, vacuum insulated, liquid nitrogen equipment and piping distribution systems, with over 3,000 dosing units installed. The company has extensive knowledge in various dosing applications.

The Challenge
The transition to screw caps in the wine industry presents challenges such as increased headspace oxygen, which can elevate dissolved oxygen levels in wine.

The Solution
Chart Inc. offers a solution by introducing liquid nitrogen into bottles post-filling, reducing headspace oxygen content by over 85%, resulting in lower dissolved oxygen levels. This method significantly reduces the need for sulfur dioxide (SO2) while maintaining acceptable free SO2 levels.

Key Benefits

Reduces headspace oxygen levels by 90-95%.
Decreases total package oxygen by 59% compared to traditional gas purging.
Minimizes SO2 requirements, allowing better control over its use.

Partial List of Customers
Includes Beringer Winery, Domaine Chandon, Napa Wine Company, and others.

Sauvignon Blanc Screw Cap Headspace Volume- 30 ml; Nozzle size = 0.050"; Bottle Type = BVS Finish Burgundy Dose Duration Headspace DO (ppm) Liquid Nitrogen Dosing Application Focus Controller Technical Specifications Model PLC Platform Preservation Wine Bottling Chart Inc. is known industry wide for its frost-free, vacuum insulated, liquid nitrogen equipment and piping distribution systems. With over 3,000 dosing units installed, Chart has a wealth of application specific knowledge across a wide range of dosing applications. The Challenge As the wine industry transitions to screw caps, wine makers are presented with new, unique challenges. Although screw caps eliminate the concern of “cork-taint”, screw cap bottles have a greater volume of headspace. Wine is exposed to oxygen trapped in the bottle headspace which in turn can result in increased dissolved oxygen levels, even after the cap is applied. Chart can help. The Solution By introducing liquid nitrogen into the bottle after filling, wine makers reduce headspace 09 content by more than 85%. Typical results are 2.0 - 2.5% 09. Less headspace 09 results in a significant reduction of dissolved 09 pickup. Chart has a complete line of liquid nitrogen dosing systems to automate and control the introduction of liquid nitrogen. A very small dose of liquid nitrogen is dosed into the filled bottle.
