Linktra® Smart Cylinders

Bringing LPG technology to the digital age

The Linktra® Smart Cylinder is our “Internet of Things” (IoT) innovation, seamlessly connecting our LPG cylinders to users’ mobile devices and to the digital systems of gas marketers.

This next-generation cylinder communicates directly with users, providing real-time insights into remaining LPG levels and predicting when a refill will be needed. At its core is a patented, Ragasco-developed wireless sensor embedded within the pressure vessel, powered by breakthrough battery technology.

Highlights

  • Seamless user experience: Users can monitor gas levels through the Linktra app and know when and where to refill, with high‑accuracy readings updated every five seconds.
  • Optimized logistics: Linktra provides insights into consumer usage patterns, enabling more efficient logistics through a cloud‑based dashboard.
  • Proven technology, built for real-world use: Based on Ragasco’s trusted composite technology, featuring maintenance‑free battery life exceeding 10 years and in‑pressure vessel, tamper‑resistant sensors that are EX‑approved and CE‑marked.
  • Lightweight and durable: Rust-free materials designed to safely deliver propane, butane and mixed liquid gas blends in a user-friendly way.
