LEWA Pumps and Metering Packages for Efficient Gas Odorization Processes

Ensuring safety, LEWA offers state-of-the-art gas odorization systems, a crucial step in rendering odorless gases like natural gas, oxygen, and nitrogen detectable. Odorization, the process of adding a distinct scent to these gases, is critical for detecting leaks and preventing hazards. LEWA's precision-engineered systems stand out in Europe as the leading solution for adding odorants to natural gas, biogas, and liquefied gas effectively.

Depend on LEWA's expertise as Europe's top provider for gas odorization, delivering turnkey solutions tailored to your specific needs. Our plug-and-play odorizing units are designed for exacting requirements, ensuring meticulous control and consistent performance in gas safety applications.

40 Years of Proven Expertise in Gas Odorization

Premium Pumps and Metering Packages

Worldwide, customers rely on LEWA’s 40-plus years of specialization in gas odorization systems. We offer a diverse range of solutions, from precision micro-metering to comprehensive gas pressure regulation technologies.

LEWA’s systems are trusted for odorizing LPG and CNG across transportation networks, as well as at gas and filling stations. A significant application of our technology is in the preparation of liquefied natural gas (LNG) at import/export terminals, ensuring safety before distribution. Additionally, our systems are integral for adding odorants to oxygen and other technical gases.

Tailored to your unique requirements, LEWA designs and assembles systems incorporating our advanced pumps, accurate flow meters, and sophisticated control systems (closed-loop control). Our approach to gas odorization is meticulous, with systems engineered to administer odorants in proportion to gas flow, ensuring precision in the injection process.
