Just Released – GPL 750 Gas Odorizer

The GPL 750 Odorization System provides odorant injection for natural gas, biogas, and propane and is now available. The 750 Odorizer is an innovative and eco-friendly approach to accurate, optimal and consistent gas odorization for low-flow, no-flow and intermittent volume applications.

What Makes the GPL 750 Different

The GPL 750 uses patented drip technology to inject a fixed measure of odorant into the gas stream ensuring accurate and repeatable odorization in the most challenging conditions. Even in low flow and intermittent flow circumstances, the 750 odorizer provides odorization proportionate to gas volume. The 750 even functions well in no-flow situations.  It is simple in design, eco-friendly and SMART (offering remote data and control capabilities). Continue reading

Gas Odorization History | From Water Gas to Natural Gas

From water gas to natural gas, the addition of an odorant to gas, or gas odorization has always been driven by the desire to keep people safe.

Town Gas Naturally Reeks

In Europe, during the early 1800s and the initial stages of the gas industry, town gas was manufactured for lighting and heating. This gas was produced from the carbonization of coal and contained mostly hydrogen and carbon monoxide and was obviously poisonous. The gas also contained sulfur compounds and innately had a gassy odor so that if there ever was a leak it was perceived through the sense of smell. Continue reading

What is Natural Gas Odorization?

What is natural gas odorization? Why do we odorize? What is the difference between an odorant, an odorizer, and odorization?

The Problem – Natural Gas is Odorless


Odorization is the first line of defense against odorless and combustible gases.

Natural gas by itself is odorless and combustible, a fatal combination. In fact, one of the worst tragedies in the United States involved a gas leak at a London, Texas school in 1937. The non-odorized gas ignited and the explosion took the lives of over 200 students and teachers.
