The GPL Odorizer is Different!

GPL Odorizers does one thing, and we take it seriously. We design and manufacture premium odorant injection systems to odorize natural gas, propane, and biogas safely.

Unlike other odorant injection systems, our odorizers do not use pipeline gas to actuate the system. Our systems do not discharge gas, nor odorant, making our models eco-friendly. There is no smell during normal operation or even maintenance because our systems have a clean, sealed and ventless design, which naturally lowers false leak-call complaints. We utilize advanced technology that saves time and money through remote monitoring, real-time mobile alerts and efficient reporting. Our systems are accurate and reliable over a wide range of flow including problematic no-flow, ultra-low-flow, and intermittent-flow systems. Our simple designs are cost-effective, competitively priced and easy to maintain and operate.

Our two models offer precise odorization for most applications:

GPL 10000 Natural Gas Odorization Package

The GPL 10000 is intended for high-pressure and high-volume applications at transmission companies and large city gate stations. The odorizer has high rangeability, achieving precision odorization over a wide operating range of volume. The industry-leading PLC interfaces with the flow meter and the system components to maintain constant odorant injection proportional to the gas flow rate.

GPL 750 Odorizer

The GPL 750 uses proprietary drip technology, permitting precise odorization in even problematic ranges, such as low-volume (even no-flow) and intermittent-volume applications. The unit is appropriate for municipalities, small city gate stations, and methane (biogas) producers. The PLC receives flow information and automatically compensates the injection rate to provide uniform odorant distribution.

Model	Min Flow MMSCFD	Max Flow MMSCFD	Min PSI	Max PSI
750	0	18	1	225
750 HC	0	24	1	225
10000	0.48	240	30	1480

Mercaptan Natural Gas Odor Injection

Natural gas by itself is odorless. In 1937 over 200 women, children and men died when un-odorized natural gas ignited in a London Texas school. This disaster was the impetus for the regulations to add odor to natural gas so that any person would detect it when having a “normal” sense of smell. An odorizer is a machine that injects the odorant into natural gas so that it is detectable. The regulation requires that the odor be detected when the gas is present at one-fifth of the lower explosive limit. Over the years countless studies have revealed that mercaptans, which are a class of organosulfur compounds, are the ideal chemicals to odorize natural gas. The chemical offers a repulsive, rotten egg smell that is readily detectable at unusually low concentrations.

GPL Odorizers does not manufacture odorants we design systems to odorize natural gas, propane, and biogas.

Eco-Friendly
No Odorant or Gas Discharge

Our patented and innovative approach does not use gas to actuate the system and has a clean, sealed, and ventless design.

Accurate and Reliable
Even in Problematic Flow Ranges

Our systems provide precision odorant injection over a wide range, including problematic no-flow, ultra-low-flow, to high-flow and high-pressure applications. Our two models offer precise odorization for most applications.

Advanced Technology
Remote Monitoring and Mobile Alerts

The GPL advanced technology saves time and money through remote monitoring, real-time communications, and efficient reporting.

Cost-Effective and Simple
Simple Solutions to Complex Challenges

Our straightforward systems are cost-effective, competitively priced and easy to maintain and operate.

GPL Odorizers (formerly Sentry Equipment and Zeck Systems) is distributed exclusively by Linc Energy Systems Inc.; a WBE Certified small business. Both companies are in Lakewood, Colorado, just outside of Denver.

The MercapMan Blog

MercapMan

MercapMan is the GPL Odorizers’ mascot. MercapMan, a/k/a the good egg, is blogging to educate the industry and public on the importance of odorizing natural gas. MercapMan, wants everyone to know that the nasty, rotten egg smell commonly associated with natural gas is there to take action! Read more on the MercapMan Blog.
