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

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.
