The Milcarb Carbo-Switch is an automatic CO₂ cylinder changeover manifold designed to provide an uninterrupted supply of gas to beverage systems. When the primary cylinder bank reaches its preset changeover pressure, the Carbo-Switch automatically switches to the reserve cylinder bank, eliminating unexpected gas outages and allowing empty cylinders to be replaced without interrupting service.

Yes. While the Milcarb Carbo-Switch is primarily used for CO₂ beverage applications, it can also be used with other non-corrosive compressed gases when the appropriate regulators and compatible materials are used. If you have questions about a specific gas or application, contact Milcarb to verify compatibility before installation.

Yes. One of the unique advantages of the Milcarb Carbo-Switch is its ability to accept third-party telemetry. By adding a compatible pressure sensor and telemetry device, users can remotely monitor cylinder pressure, receive low-pressure notifications, and better manage cylinder replacements without replacing the existing changeover manifold.

The Milcarb Carbo-Switch is available in three standard cylinder configurations to accommodate a variety of gas usage requirements. Current standard options include:2-Tank System (1 × 1) – One primary cylinder and one reserve cylinder.3-Tank System (2 × 1) – Two primary cylinders and one reserve cylinder.5-Tank System (4 × 1) – Four primary cylinders and one reserve cylinder. These configurations provide flexibility for applications ranging from smaller beverage systems to higher-volume operations. If you're unsure which configuration is right for your application, the Milcarb team can help recommend the best option based on your gas usage and cylinder replacement frequency.

No. While Milcarb offers three standard Carbo-Switch configurations, the system can be expanded to accommodate additional cylinders as your gas demand increases.For the simplest installation, Milcarb recommends selecting the appropriate cylinder configuration when the system is originally ordered. If your application grows over time, additional cylinders can be added using Milcarb-approved high-pressure expansion fittings. Because these fittings require proper thread sealing and assembly during installation, expansion is possible but is typically more convenient when the desired cylinder configuration is specified at the time of purchase.

The Milcarb Carbo-Switch is designed so all cylinders connected to the primary bank are manifolded together and supply gas as a single source. As gas is consumed, the pressure in the entire primary bank decreases together rather than one cylinder emptying at a time.When the pressure in the primary bank drops to approximately 200 PSI, the Carbo-Switch automatically changes over to the reserve cylinder bank, providing a continuous flow of CO₂ without service interruption to your beverage equipment.After the changeover occurs, the depleted primary cylinders are removed and sent for refill. The reserve cylinders, now supplying gas to the system, are moved to the primary side, and the newly filled cylinders are installed as the new reserve bank. This rotation ensures the Carbo-Switch is always prepared for the next automatic changeover while maintaining a continuous flow of CO₂ without service interruption.

Each cylinder connected to the Milcarb Carbo-Switch has its own pressure gauge. The gauge reading indicates the amount of CO₂ remaining in that cylinder, making it easy to identify which cylinders have been depleted and require replacement.After the Carbo-Switch changes over, the cylinders on the primary side will have reached their usable pressure and should be removed for refill. Once refilled, those cylinders are installed as the new reserve bank, while the previous reserve bank continues as the primary supply. This rotation keeps the Carbo-Switch prepared for the next automatic changeover while maintaining a continuous flow of CO₂ without service interruption.

Yes. With the proper tools and mounting hardware, the Milcarb Carbo-Switch can be installed by anyone familiar with high-pressure CO₂ systems. The Carbo-Switch is designed to be securely mounted to a wall or other suitable surface before connecting the CO₂ cylinders.After installation, slowly open the cylinder valves and verify all connections are leak-free using an approved leak detection solution. An additional way to verify the system is leak-free is to use your existing CO₂ primary regulator or a newly purchased CO₂ primary regulator. Once the system is pressurized, close the cylinder valves and monitor the regulator's supply gauge while the system is inactive. If the gauge pressure remains steady, the system is holding pressure. A noticeable pressure drop may indicate a leak that should be located and repaired before placing the system into service.Once the installation has been verified, the Carbo-Switch will automatically manage the changeover between the primary and reserve cylinder banks.If you have questions during installation, Milcarb's technical support team is available by phone, email, text, and even live video calls to help ensure your installation goes smoothly.

The Milcarb Carbo-Switch is designed to provide years of reliable service with very little routine maintenance. Periodically inspect the manifold, regulators, pigtails, and fittings for signs of wear, damage, or leaks. Any worn hoses, fittings, or gauges should be replaced before returning the system to service.Each time cylinders are exchanged, it is also a good practice to perform a leak check using an approved leak detection solution and verify all gauges are operating properly. Keeping the system clean and free of physical damage will help ensure dependable operation and long service life.If service or replacement parts are ever needed, Milcarb's technical support team can assist with troubleshooting and provide genuine replacement components.

The Milcarb Carbo-Switch is an economical alternative to many automatic cylinder changeover systems on the market while delivering the reliability and flexibility required for a wide range of CO₂ applications. Available in multiple standard cylinder configurations, the system can also be expanded as your gas requirements grow, helping protect your investment for years to come.Unlike many changeover manifolds, the Milcarb Carbo-Switch can be equipped with third-party telemetry, allowing you to remotely monitor cylinder status and receive low-pressure alerts without replacing your existing changeover system. Its straightforward mechanical design also makes installation, operation, and future expansion simple.Whether you're serving a small restaurant, brewery, coffee shop, or a larger beverage operation, the Milcarb Carbo-Switch provides dependable automatic cylinder changeover with the flexibility to adapt as your business grows.
