Soda-Club's Carbonators are made of light weight aluminum. We maintain the highest quality standards and we ensure safety and security of our CO₂ refills.Our carbonators are available in various sizes, allowing for 60 to 130 liters of carbonated drinks per carbonator. A full CO₂ carbonator is included with the purchase of our system. When the gas in the carbonator finishes, consumers exchange the empty carbonators for a full one, paying only the cost of a gas refill.
