Vapor combustion units provide an enclosed solution for burning hydrocarbon vapors from oil and gas production sites.
Onit Energy Solutions designs, builds, services, and upgrades vapor combustion units for operators throughout West Texas, the Permian Basin, and Southeast New Mexico. Our systems are built to support cleaner combustion, reliable operation, and practical field service.

A vapor combustion unit works much like an enclosed flare, burning gas inside a combustion chamber instead of exposing the flame through an open flare tip.
VCUs are often used for lower-volume vapor streams, tank battery applications, and facilities where visible flame, smoke, noise, radiant heat, or nearby development create additional operational concerns.
Onit provides VCU specifications and sizing support based on anticipated flow, turndown requirements, gas quality, regulatory constraints, and site conditions. Final VCU selection and sizing are confirmed by Onit Energy Solutions before fabrication.
Enclosed combustion systems designed to control and combust hydrocarbon vapors from production facilities and tank batteries.
Onit helps evaluate factors such as vapor flow, burner performance, pilot reliability, flame monitoring, airflow, data logging, and nuisance impacts such as visible emissions, noise, and radiant heat. Our goal is to help your system burn cleanly, operate safely, and support current emissions expectations.


A vapor combustion unit is only valuable if it performs reliably in the field.
Onit Energy Solutions provides service, repair, maintenance, and retrofit support for vapor combustion units used in oil and gas operations. Whether you need a new VCU, troubleshooting for an existing system, or upgrades to improve combustion performance, our team is ready to help.
