GPL Odorizers - Natural Gas Odorization and Odorant Injection Systems
GPL Odorizers designs and manufactures environmentally-friendly odorant injection systems to safely odorize natural gas, propane, biomethane (renewable natural gas), and biogas. Unlike other systems, our odorizers are ventless and do not discharge gas into the atmosphere, making GPL Odorizers the most planet-friendly odorant injection system on the market. Our odorizers are self-contained; they do not release gas, which improves safety, saves pipeline gas, reduces odor, and, subsequently, lowers leak call complaints.
Additionally, GPL Odorizers have fewer moving parts than the leading competitive odorization systems, which means less maintenance over the unit’s life. At GPL Odorizers, we believe simple is better and strive to provide planet-friendly solutions.
Our Odorization Systems
GPL Odorizers 750
The GPL 750 provides accurate and optimal natural gas odorization in low flow (even no flow) and intermittent gas flow systems. The GPL 750 is for systems ranging from no flow to 750 MCFH and up to 250 psi. It is simple in design, eco-responsible, and SMART, offering remote data and control capabilities.
The GPL 10000 (formerly the Sentry Equipment and Zeck Systems Z10000) is the ideal odorant injection system for high-volume and high-pressure applications. The unit provides accurate odorization for gas with flow rates from 10,000K to 10,000,000 SCFH with excellent full-range accuracy (0.2%) for pipelines with pressure up to 1480 PSI.
Please note that the GPL 750 has replaced the Z9000.
The GPL Z9000 was first introduced in 2003 (Zeck Systems Z9000) as a safe, accurate, and straightforward solution for odorizing pipelines with gas flow ranging from 1,000 to 750,000 SCFH when pressures are below 250 PSI. It is a proven system with communication features that make the unit ideal for remote gas well locations. Given its small physical footprint, it’s also perfect for urban city gates. The Z9000 has been replaced by the GPL 750.

Odorant Injection Skids
GPL Odorizers designs permanent low- and high-pressure natural gas, propane, and biogas odorant injection systems in various configurations. Read More.
Temporary or Gas Pickling Systems
GPL Odorizers designs low- and high-pressure temporary odorization systems for natural gas, propane, and biogas. Pickling units are available. Read More.
Accessories & Upgrades
To add the extra level of protection, GPL Odorizers offers the upgrade of a Shelter Works custom-built fiberglass building to house the entire natural gas odorant injection system.
GPL 100 Thermal Mass Flow Meter
The GPL 100 thermal mass flow meter is recommended for use with the GPL 750 Odorization System as it has excellent low flow sensitivity and high rangeability. Read our case study, “Odorizer and Flow Meter Solve Low-Flow Odorization Challenges.”
Portable Turnkey Odorant Injection System
The GPL-750-V-120-P is a portable odorant injection system designed for ease of installation and portability. A built-in metal pallet permits a forklift or pallet jack to transfer the system easily. While this is not a temporary system, its built-in movability allows the user to move the unit to another application if so needed. Read More.
About Gas Odorization
Natural gas (and propane) by itself is odorless and combustible. If ignitable gases are undetected, an unsafe and potentially disastrous condition exists. The impetus to add odor (odorize) to natural gas and other gases amplified after non-odorized natural gas ignited in a Texas school, killing over 200 children in 1937. Today, federal regulations mandate combustible gas’s odorization so that odorized gas can smell (49 CFR 192.625).
Features and Benefits
Ventless (no gas discharged)
Few moving parts
Excellent full-range accuracy
Our Odorizer History
For three generations, the Zeck family was the pioneer in designing and developing accurate yet straightforward natural gas odorization systems. In 2003, Zeck Systems introduced the Z9000 as a simplified and efficient approach to self-contained odorant injection systems with few moving parts. In 2010, Sentry Equipment Corp acquired Zeck Systems. GPL Odorizers acquired Sentry Equipment’s odorization product line assets in 2015 and continues manufacturing Zeck Systems’ innovative odorization products.

What is odor fade? What causes odor loss in odorized natural gas?
What is odor fade? While smelling natural gas is the first warning that there is a gas leak, it is not foolproof. One of those reasons is the diminishing odor of odorized gas. Read More >
