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.

Application Spectrum for Gas Odorization: LEWA Pumps and Metering Packages
LEWA's advanced odorizing systems are versatile enough to infuse a variety of odorants into multiple gases, including natural gas from 1 to 300 bar, biogas within the same pressure range, as well as LPG, oxygen, nitrogen, carbon dioxide, hydrogen, LNG, and even unconventional gases. Our robust pumps and precision metering packages ensure that no matter the gas, the odorization process is efficient and reliable
