GPL Odorizers logo

GPL Odorizers manufactures environmentally-friendly odorant injection systems for natural gas and other gases. Unlike other systems, our odorizers are ventless, and they 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, therefore, do not release gas, and this 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. This means less maintenance over the life of the unit.

At GPL Odorizers, we believe simple is better and strive to provide planet-friendly solutions.

Our Odorant Injection Systems

GPL 750

(Patented)
GPL 750 odorant injectionThe 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.

GPL Z10000

(Patented)

odorization by GPL OdorizersThe GPL Z10000 (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.

GPL Z9000

(Patented)

GPL Z9000 odorizerThe GPL Z9000 was first introduced in 2003 (Zeck Systems Z9000) as the safe, simple and accurate solution for odorizing pipelines with gas flow ranging 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, yet given its small physical footprint it's also perfect for urban city gates. Given that there are only two moving parts, most issues may be investigated remotely.

About Gas Odorization

Natural gas (and propane) by itself is odorless and combustible. If ignitable gases are undetected, an unsafe and potentially disastrous condition is produced. The impetus to add odor (odorize) to natural gas and other gases was created after non-odorized natural gas ignited in a Texas school, killing over 200 children in 1937. Today, federal regulations mandate the odorization of combustible gases so that gas can readily be perceived by its odorized smell (49 CFR 192.625).

Features and Benefits

Ventless (no gas discharged)
  • Improved safety
  • Saves pipeline gas
  • Environmentally friendly
  • Lowers leak call complaints

Few moving parts

  • Low maintenance cost
Excellent full range accuracy

Our History

For three generations, the Zeck family was the pioneer in the design and development of simple, yet accurate, 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, Zeck Systems was acquired by Sentry Equipment Corp. GPL Odorizers acquired the assets of the Sentry Equipment's odorization product line in 2015 and continues to manufacture the Zeck Systems and Sentry Equipment Corp innovative odorization products in Wheat Ridge, Colorado.
