During routine gas utility operations, maintenance and construction activity, natural gas is often stranded in a section of pipe. The ULC DDC-125 Drawdown Compressor enables gas utilities to extract the stranded natural gas from the isolated section of main, compress it, and inject it back into the active system to support zero emissions goals and mitigate odor complaints.
01. Drawdown to Zero PSI
The ULC Drawdown Compressor is able to take isolated gas operating at up to 300psi and draw it down to zero to completely eliminate emissions due to venting.
02. Powered by Natural Gas
The unit runs off natural gas from the active pipeline network. It never runs out of fuel and does not require air compressors to be delivered to the site.
03. Loaded With Safety Features
The Drawdown Compressor automatically pauses operation when adverse conditions are detected. Blow-offs on the manifolds also protect against over pressurization.
04. Automatically Cools Natural Gas
A built-in radiator engages when natural gas reaches temperatures above 100° F to ensure gas being injected into the active system stays below 140°F.
05. Supports Zero Emissions Goals
Elimination of venting natural gas during routine operations, maintenance and construction activities supports emissions reduction and environmental goals.
06. Wide Range of Applications
Customers refer to the Drawdown Compressor as a ‘one-stop-shop’ tool that can handle large volumes
of natural gas with just one unit on site.
Keep Natural Gas in the Distribution System and Out of the Atmosphere!
Built to reduce emissions of gas distribution maintenance operations, pipeline replacement programs, main abandonments and other routine work performed daily by utilities.
In this 30-minute webinar our team will provide a deeper dive into the new ULC Drawdown Compressor by reviewing the system specifications, detailing the unit operations and sharing successful use cases. Attendees will understand how natural gas is moved from the isolated section of pipe, through the compressor and back into the active gas main and have an opportunity to ask questions.

System Specifications:
The Drawdown Compressor uses a belt-driven piston compressor powered by a natural gas driven engine and control panel to extract stranded natural gas, compress it, and inject it back into the active gas main.
Safety:
Automated safety features pause operations for abnormal conditions such as:
