ODORANT INJECTION
GPL Odorizers designs and manufactures odorant injection systems to safely odorize natural gas, propane, biomethane (renewable natural gas), and biogas.

Natural Gas Odorizers for Our Future
Accurate and Reliable
Even in Problematic Flow Ranges
Precision chemical injection into gases over a wide range, including problematic no-flow, ultra-low-flow, to high-flow and high-pressure uses
Cutting-Edge Technology
Adaptive Touchscreen Controller
Advanced electronic components save time and money. Remote monitoring, real-time communications, and efficient reporting
Easy & Inexpensive Operation
Simple Solutions to Complex Challenges
Straightforward systems, cost-effective, easy to maintain and operate with few moving parts, and no smelly pumps to maintain
No Odorant or Gas Discharge
No-Smell Operation, Eco-Friendly
The patented and innovative approach does not use gas to actuate the system. Clean, closed-loop, and ventless design
Precise Odorization for Most Applications







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



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