Core Applications

1. Life-Saving Equipment
Emergency life jackets equipped with CO₂ cylinders enable rapid inflation in just 0.5 seconds, ensuring immediate flotation support in critical rescue scenarios. Reliable gas discharge and compact design make them ideal for maritime and aviation safety kits.

2. Nano Aquariums
CO₂ cylinders provide stable and precise carbon dioxide delivery for small aquariums ranging from 5 to 30 liters. This promotes optimal plant growth and ecosystem balance, essential for aquascaping and aquatic plant cultivation.

3. Fire Safety
CO₂ cylinders are effective against Class B fires (flammable liquids and electrical fires), making them ideal for use in laboratories, kitchens, and enclosed technical spaces. They provide a clean, residue-free suppression method that minimizes equipment damage and downtime.
