Odorizing Process

Odorizing is a process of adding acrid substances (odorants –mercaptans) to heating oils in order to signal the leak of such gases. Our odorizing systems have been manufactured since 1995 and thanks to long-term experience comply with technical trends and safety regulations. These products are our most successful ones.

In order to be able to mix the odorant into the gas, it is necessary to design a special dosing principle. For this purpose the injection technology is used. Here, the odorant is mixed into the gas economically and efficiently in precise doses. This achieves the required safe odor, economy of operation and no overdose.

OSGC Odorization Systems

The core of our OSGC odorization systems is a LEWA diaphragm pump or a WILLIAMS pneumatic dispenser. These devices are self-sucking and do not require additional energy to suck odorant from the tank. The entire system of the odorization device is tight and made of materials that guarantee the reliability of the device and at the same time eliminate any leakage of the system.


Odorization stations are suitable for all types of odorants. They are produced in several designs. According to the customer’s demand, these stations can be adapted to his requirements.



Technical parameters of odorization stations: TP of OS


DAMEOD-MINI is a device that monitors odorant concentration. DAMEOD-MINI may be installed directly in ZONE 2 with explosion hazard, or outside in the “stainless” version. The advantages of DAMEOD include that operators do not have to check odorant concentration in the end branches with manual devices, but they can comfortably monitor these values from the control room.

It allows them to remotely set the required values of mg/Nm3 in odorizing stations, which ensures significant savings. Also, data can be printed in the form of a protocol or in a chart to document retrospectively concentrations on particular days and time.

The device can be fed via UPS (located outside ZONE 2).

Readings are taken by sensors that are standardly fitted in the portable metering devices used for measuring odorant concentrations.

In case of a “full” utilization of the control automat, it is possible to add three* analogue sensors, door contacts or other binary signals (such as capacity sensors of the position of safety quick-closing valves etc.).
