Tritium (³H) is a radioactive isotope of hydrogen, made up of one proton and two neutrons. Found in nuclear fusion applications, scientific research, and advanced energy technologies, it stands out for two characteristics that make it one of the most demanding gases to handle: exceptionally high diffusivity and strict safety requirements.

A gas pressure regulator is a spring-loaded control device designed to regulate pressure and keep it stable at the outlet, even when inlet conditions fluctuate. Using a sensing element such as a diaphragm or piston, it automatically balances forces to maintain safe operating conditions. In industrial environments where gases are stored and distributed at high pressure (sometimes several thousand psi) precise control is not optional; it is critical for safety, process stability, and regulatory compliance.  In this article, you’ll discover how pressure regulators work, their key components, the physics behind their operation, and why high-performance solutions from Rotarex are trusted worldwide.

At the heart of our relationship with our customers, the Customer Service teams play a key role at Rotarex. Based within the various Business Units, they serve as the link between customers and all internal departments, ensuring smooth and efficient handling of orders and requests.

Solar energy is widely recognized as a cornerstone of the global energy transition. Behind every high-efficiency solar panel, however, lies a highly sophisticated manufacturing process where precision, purity, and process stability are essential. From silicon diffusion to thin-film deposition and cell processing, photovoltaic manufacturing relies heavily on high-purity gases, with ultra-high purity requirements in selected critical process steps such as thin-film deposition, and on the components that control, regulate, and safely distribute them. At these critical points in the manufacturing flow, Rotarex provides adapted gas delivery functions derived from semiconductor-grade technologies, optimized for photovoltaic manufacturing requirements, supporting performance, safety, and yield.

From hydrogen infrastructure and rocket launch systems to advanced research laboratories, cryogenic gases play a central role in enabling high-technology innovation. These industries rely on ultra-low and stable cryogenic temperatures, precise pressure control, temperature control and safe storage conditions to achieve performance levels that would otherwise be impossible.
Cryogenic storage systems, including insulated storage tanks and specialized cryogenic tanks, are essential to maintain liquid storage conditions and ensure safe handling of gases in extreme cold environments across industrial plants.  Effective cryogenic gas management is therefore not only a technical requirement but a strategic necessity. Ensuring reliability, cryogenic safety and operational efficiency across these demanding environments is key to supporting the next generation of energy systems, electronics and scientific breakthroughs.

Often discreet but absolutely essential, the IT Infra Project & Maintenance team is central to Rotarex's smooth operation. Every day, it ensures the stability, security and performance of all IT systems, enabling all employees to work in the best possible conditions.

When it comes to storage, distribution and transport in gas or cryogenic systems, Rotarex Bellows Valves set the benchmark for tightness, safety, and efficiency. Designed for the most demanding conditions, they ensure zero leakage, high flow capacity and long-term reliability from gas production and transportation to end-user applications.

Nitric oxide (NO), often referred to as a “miracle gas,” plays a vital role in modern medicine. Used alongside oxygen therapy, it effectively treats severe conditions and improves patients’ quality of life.

At Rotarex, the Marketing department plays a key role. Responsible for the company's image, it ensures that the right message is communicated at the right time and through the right channels. But its role goes further : it also contributes to internal communication, promoting cohesion and information sharing.

The semiconductor industry is experiencing unprecedented growth. Beyond traditional electronics such as computers, smartphones, and digital displays, demand is now fueled by cutting-edge technologies like artificial intelligence (AI), 5G/6G, cloud computing, electric vehicles, and the Internet of Things (IoT).
