Gas Odorization with LEWA Pumps and Metering Packages

Natural gas, oxygen, and nitrogen are odorless but potentially dangerous. This is why these gases are "odorized" with as strong a smelling substance as possible. This process is enormously important, so the odorizing system has to operate precisely and reliably.

You can trust in the systems from LEWA, Europe's market leader for the odorization of gases such as natural gas, biogas, and liquefied gas. We supply you with a ready-to-connect odorizing system that meets your requirements exactly.

Gas Odorization

40 Years of Experience Make LEWA Number One

Customers all over the world have been putting their trust in LEWA systems for more than 40 years when it comes to odorizing gas. Our portfolio of solutions for this application ranges from systems for micro-metering through to gas pressure regulation stations.

Scores of suppliers also put their trust in LEWA systems for odorizing LPG and CNG in the complete transport chain, as well as in gas stations and filling stations. Another large area of application for our systems is liquefied natural gas (LNG) in import/export terminals before distribution. And last but not least, LEWA odorizing systems are also used for odorizing oxygen and technical gases.

We plan and produce systems based on your specifications and, of course, equip them with LEWA core components: Pumps, flow meters, and a control system (closed control loop). Our systems use quantity-based odorization, controlled by the gas flow (injection process).
