ZEVAC® = Zero Emission Vacuum and Compressor. The ZEVAC® provides zero venting, zero flaring, zero emissions and is the environmentally responsible way to handle natural gas in the pipeline. These units use compressed air to suction natural gas from a pipeline segment and compress it into the adjacent connection – keeping the gas inside the pressurized system the entire time.

ZEVAC® is the property of TPE Midstream LLC. Visit tpemidstream.com for more information.
