LEWA odorizing systems

LEWA Odorizing Systems

Trust in odorizing systems from the market leader: LEWA supplies complete solutions consisting of pumps, tanks, and measuring and regulation units.

For over 40 years, LEWA has been building odorizing systems for natural gas, oxygen, nitrogen, carbon dioxide, and other gases. Our systems have flow rates of 0 l/h to 40 l/hand a discharge pressure between 2 bar and 300 bar.

LEWA odorizing systems

Safe gas odorizing in accordance with global regulations.

Odorizing gases is a complex task. The global regulations governing this application are strict and not always clear: In the past, gas suppliers relied on wick odorization, by-pass odorization, or simply adding odorants with no means of control. Today, this is prohibited in virtually every country – odorization must be monitored and performed proportionally and continuously.

LEWA has the expertise that comes with 40 years of experience and the necessary equipment to create your safe and regulation-compliant odorizing system. We adapt our systems to conform with country-specific standards and requirements. Whether odorization is decentralized or – as is the case in France, for example – takes place at a central location,

with LEWA odorizing systems you're placing your trust in the expertise of the market leader for efficient and safe gas odorization.

Options

Housing for the system

We offer a complete housing for your Odorization System. This is usually a stainless steel cabinet. We also provide special material housings.

Overfilling protection and leakage pan

Specially designed accessories: With a reliable overfill protection and leakage pans in different sizes, you get a clean and safe system.

Flushing system for easy cleaning

For easy and regular maintenance of the system, we recommend a flushing system for the pump, the piping and the tank for an odor-free disassembly and maintenance.

Design with safety valve

Designed for elavated suction pressures with pressure relief valve (0,5-3,0 bar).

Solenoid valve and pressure gauge

With a solenoid valve in the discharge line, you can control small gas flow rates (< 400 Nm3/h). A manometer for pressure pipes and tanks ensures the exact metering of the fluid.

Testing, acceptance and inspection

We make sure that everything works: LEWA offers numerous services, including factory acceptance test (FAT) at the manufacturing site or at your site (SAT), NDT and PMI.

Additional stand-by pumps

Efficiency and reliable operation of our systems are in focus: We provide additional stand-by pumps for easy system maintenance without downtime.

Suitable for all odorants

LEWA odorizing systems are suitable for all common odorants in the industry: EM, DMS, TBM, THT. Simply let us know your personal requirements.
