Products Details
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.
Each LEWA odorizing system consists of standard components such as the control system, pump, vessel, trough, flow meter, lines & valves, and accessories. These components can be configured on a custom basis and in complete accordance with your requirements.
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.
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)).
With LEWA odorizing systems, you can add a special odorant to various gases: natural gas, biogas, LPG, oxygen, nitrogen, carbon dioxide, hydrogen, methane, and many more besides.
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 LEWA KMM 1 flow meter is unique on the market and is able to measure even the lowest volume flows with absolute precision.
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.
Thanks to our network of global branch offices and sales partners, you'll get the best service and spare parts for your odorizing systems as quickly as possible.
Options
We offer a complete housing for your Odorization System. This is usually a stainless steel cabinet. We also provide special material housings.
Specially designed accessories: With a reliable overfill protection and leakage pans in different sizes, you get a clean and safe system.
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.
Designed for elavated suction pressures with pressure relief valve (0,5-3,0 bar).
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.
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.
Efficiency and reliable operation of our systems are in focus: We provide additional stand-by pumps for easy system maintenance without downtime.
LEWA odorizing systems are suitable for all common odorants in the industry: EM, DMS, TBM, THT. Simply let us know your personal requirements.
Modular design
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
