LEWA odorizes gas: Custom units or tried-and-tested systems – we supply exactly what you need!
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.
A LEWA odorizing system is a quantity-dependent, gas flow-controlled system with closed loop control and a design that complies with applicable guidelines (including the German Federal Water Act (WHG), German Technical and Scientific Association for Gas and Water (DVGW), ATEX, GOST-R, ASME, Pressure Equipment Directive, German Technical Instructions on Air Quality Control (TA-Luft), and German Technical Regulations for Combustible Liquids (TRbF)).
Our odorizing systems use only tried-and-tested and approved components, while our diaphragm pumps are completely sealed and offer full reliability during metering. Control elements are also available in an Ex-protected design. We also supply magnetic, pneumatic or electrically powered pumps on request.
LEWA odorizing systems are suitable for all odorants. For many years now, our systems have been metering EM, DMS, TBM, THT, and sulfur-free substances for numerous customers with reliability and the utmost precision.
The process of odorizing gases is dependent on exact metering accuracy. LEWA odorizing systems achieve a precision level of ±1%.
The vessels are fitted with a visual fill level control which can be used while the pumps are being calibrated.
The metal pump diaphragms are completely diffusion-proof and fail-safe.
LEWA odorizing systems are suitable for all common odorants in the industry: EM, DMS, TBM, THT. Simply let us know your personal requirements.
You are free to choose: Standard odorizing systems are designed to be highly modular and consist of various components which enables us to meet your requirements in a manner that is as flexible as possible.
The LEWA metering systems have a modular structure. Various tanks, line systems, and pumps allow us to adapt every system to the requirements of our customers.
