ZEVAC Equipment

How It Works

ZEVAC moves gas/liquids through cross-compression, from one pressurized system to another, through a set of intake and discharge hose connections. Trapped gas/liquids or contents, which would normally be vented or escape during repairs are drawn into the ZEVAC and transferred into a nearby operational piping system or containment, resulting in zero emissions escaping into the atmosphere.

The ZEVAC is powered pneumatically by connecting a compressed air source (generally an air compressor) to its air intake location. Any compressed air source can power the ZEVAC; the more air it receives, the faster the job gets done. 

Dynamic Pressure Match

ZEVAC utilizes positive displacement linear compressors, means there is no spinning crankshaft or rotating drivetrain. This key feature affords ZEVAC equipment unique functionality and advantages, such as the capability to capture and recover product contents from 100% dry gas; to any percentage of wet gas mixtures; and even up to 100% liquid service. 

We take your service conditions as they are. Without the need to regulate gas pressure into the ZEVAC, we maximize the speed of the gas transfer. Automatically adjusting the ZEVAC discharge pressure to match your system's operating pressure remove the risk of regulator failure and over-pressurization. Together, these features make up the Dynamic Pressure Match.
