How Pressure Regulators Improve Safety in Hydrogen Refuelling Stations
Hydrogen refuelling stations (HRS) are essential to supporting the transition to zero-emission transport. With hydrogen stored at pressures up to 700 bar, effective pressure regulation is critical to ensure safe and stable operation. Let’s look at the role they play. Pressure regulators control the pressure of hydrogen from high-pressure storage to vehicle systems, maintaining consistent output pressure while protecting downstream components. The control element is critical because without it, there’s a risk of over-pressurisation, and even equipment failure. At Pressure Tech, we have a range of regulators designed specifically for hydrogen service. Body and component material selection are of utmost importance to ensure strength, longevity, and resistance to hydrogen embrittlement. Hydrogen embrittlement is a form of material degradation where metals become brittle and crack due to the absorption and diffusion of hydrogen atoms into the metal—especially under stress. Additional safety measures, such as integrated filters and optional venting, help prevent contamination damage and provide protection in overpressure scenarios. Positive Material Identification (PMI) testing and full material traceability further enhance quality assurance. In line with the growing hydrogen infrastructure, the demand for robust, reliable pressure control is also increasing. Selecting the right pressure regulator doesn’t just optimise performance—it protects people, equipment, and long-term investment. For OEMs and station developers, high-quality regulation is a fundamental part of building a safe and efficient hydrogen refuelling network.

Pressure Regulation for Gas Analysers: What Engineers Need to Know
Precise and stable pressure control is critical in ensuring the accuracy and reliability of gas analysers. Whether monitoring trace gases in environmental labs or measuring process gases in industrial plants, the performance of analytical instruments depends heavily on the quality of the pressure regulation upstream. Gas analyser regulators are designed to deliver consistent, low-pressure gas flow to sensitive equipment, regardless of fluctuations in the inlet pressure. Any instability or contamination can distort readings, damage sensors, or potentially shorten the analyser’s lifespan. Engineers specifying pressure control for analytical instruments must consider key factors such as outlet pressure accuracy, material compatibility, and internal volume. For example, stainless steel regulators with low internal volume help minimise sample retention and improve response times—especially important when analysing corrosive or reactive gases. At Pressure Tech, our regulators for gas analysers offer fine control, leak-tight performance, and compatibility with corrosive gases. Features like PTFE seating, surface finish options, and integrated filtration make them ideal for laboratory and field-based systems alike. Choosing the right gas analyser regulator isn’t just about flow—it’s about protecting your data, your equipment, and your reputation. For engineers looking to improve the precision and reliability of their gas analysis, pressure regulation is the first place to get it right.
