Carbon Dioxide Polishers

Carbon dioxide is used within beverage production in brewing, sparkling wine and in soft drink for carbonation of the finished product and for inert storage of flavorings.

Quality Guidelines for producers of beverage CO2 are issued by organizations such as the International Society of Beverage Technologists (ISBT) in the US and the European Industrial Gases Association (EIGA). However, potential CO2 impurities may still occur as a result of trace contaminants being carried over in the source gas or by being introduced into the bulk liquid CO2 during storage and transportation.

In response to increased awareness to the impact on beverage characteristics that potential impurities can have, Parker domnick hunter has developed a range of PCO2 carbon dioxide gas polishers, designed to act as quality incident protection units to help in protecting the final beverage against possible flavor defects and hazards. Potential CO2 impurities known to have flavor impact on beverages include volatile organic compounds (VOCs), aromatic hydrocarbons, acetaldehyde and sulphur compounds.

Parker domnick hunter’s unique PCO2 systems for retail point of use and plant scale operations are recognized as the industry’s preferred choice for CO2 polishing systems and are used in over 150 countries worldwide.
