EcoVenza 2.2L CO₂ cylinders use the industry-standard M10 thread and are compatible with a wide range of sparkling water systems, including:

• Zip™
• Billi™
• Waterlogic™
• Puretec™
• Bromic™
• Crystella™ systems using compatible 2.2L regulators
• Most other systems designed for 2.2L M10-thread CO₂ cylinders

EcoVenza cylinders can be used as a direct replacement for compatible Zip™ and Billi™ 2.2L CO₂ cylinders without modifying your system.

If you're unsure whether an EcoVenza cylinder will fit your sparkling water system, check your existing cylinder or regulator for an M10 connection or contact EcoVenza for assistance.

Replacing an empty EcoVenza CO₂ cylinder is straightforward and can be done without a technician.

1. Turn off the regulator connected to the empty cylinder. The pressure gauge should drop to zero.
2. Unscrew the regulator from the empty cylinder and set it aside.
3. Remove the protective cap from the full EcoVenza cylinder.
4. Attach the regulator to the new cylinder and tighten it securely. You may hear a brief "whoosh" as you connect it. This is a small release of CO₂ gas and is normal.
5. Turn the regulator on and adjust the pressure to approximately 3.5 bar.

Food-grade CO₂ is non-toxic and non-flammable. However, CO₂ cylinders are pressurised vessels and should always be handled and stored with care.

Each EcoVenza 2.2L cylinder contains 1,300g of food-grade CO₂ and can produce up to approximately 260 litres of sparkling water.

EcoVenza cylinders contain up to 20% more CO₂ than many alternative cylinders, helping reduce the frequency of cylinder replacements while providing better value per litre of sparkling water.

Please note that actual consumption can vary depending on how your sparkling water system is used and your preferred level of carbonation.

Yes. EcoVenza cylinders contain food-grade CO₂, which is non-toxic and non-flammable.

However, CO₂ cylinders are pressurised vessels and must be handled and stored correctly. Keep cylinders secure and protected from damage, tampering and access by children.

Because pressurised CO₂ cylinders are classified as Dangerous Goods for transport, EcoVenza uses specialist Dangerous Goods couriers for cylinder deliveries and collections.

For additional safety information, refer to the Safety Data Sheet (SDS/MSDS) for EcoVenza cylinders.

ReCylinder™ is EcoVenza's CO₂ cylinder recycling program, designed to make responsible disposal of used 2.2L cylinders simple and convenient.

When you purchase eligible EcoVenza cylinders, you receive ReCylinder™ credits that can be used to arrange free collection of your empty cylinders for recycling.

Once your cylinders are empty, pack them securely in the reusable EcoVenza carton, book your collection through your EcoVenza account and leave the sealed carton ready for the courier to collect.

EcoVenza then collects the cylinders and sends them for responsible recycling, providing a convenient alternative to disposing of pressurised cylinders yourself.

For more information about responsible CO₂ cylinder disposal, read our CO₂ cylinder recycling guide.

ReCylinder™ credits are included with EcoVenza twin-pack CO₂ cylinder purchases and can be used to arrange free collection of your empty cylinders for recycling.

Each twin-pack includes one ReCylinder™ credit:

• 1 twin-pack = 1 credit = collection of 2 empty cylinders
• 2 twin-packs = 2 credits = collection of 4 empty cylinders
• Additional twin-packs provide additional credits

Each ReCylinder™ credit is valid for 12 months from the original purchase date.

Empty cylinders must be packed in the original reusable EcoVenza carton so they can be transported safely and in accordance with courier requirements.
