ZEVAC Twin

The ZEVAC Twin delivers an effective combination of portability and performance for pipeline evacuation and emissions reduction applications. Designed to fit in the bed of a pickup truck or on a trailer, this unit provides contractors and utility operators with a mobile solution for recovering gas and liquids during maintenance, pigging, tie-ins, and pipeline depressurization projects.

Unlike conventional systems, the ZEVAC Twin uses compressed air rather than electricity, making it well-suited for hazardous jobsite environments. Its mechanical design allows operators to recover product streams ranging from dry gas to 100% liquid service, helping reduce methane emissions, preserve product value, and improve jobsite safety.

Ideal for utility companies, pipeline contractors, and energy operators, the Twin supports regulatory compliance initiatives while minimizing environmental impact and operational downtime.

Key Features

• Portable Design - Sized for transport in a pickup truck bed or trailer.
• Air-Powered Operation - Operates using compressed air with no electrical power required.
• Cross-Compression Capability - Transfers recoverable gas from one section of pipeline to another rather than venting to atmosphere.
• Handles Gas and Liquids - Capable of recovering contents ranging from 100% gas to 100% liquid mixtures.
• Emission Reduction Technology - Helps reduce methane emissions by keeping product within the pipeline system.
• Quiet Operation - Includes a noise suppression silencer rated below 85 dB.
• Pipeline Drawdown Performance - Designed to evacuate pipelines down to 0 psi for effective product recovery.

Benefits

• Improve Regulatory Compliance
  Supports methane emissions reduction initiatives and helps operators meet environmental regulations by minimizing venting and flaring activities.
• Increase Safety on Active Gas Systems
  Keeping product inside the pipeline reduces risks associated with atmospheric releases, ignition hazards, and worker exposure.
• Reduce Product Loss
  Recovered gas remains within the system, helping utilities and pipeline operators preserve valuable product and reduce waste.
• Accelerate Jobsite Deployment
  Portable dimensions and simple line connections allow crews to mobilize quickly across multiple project locations.
• Operate in Remote Locations
  Compressed-air operation eliminates dependency on electrical infrastructure, making the unit suitable for remote and challenging work environments.

Frequently Asked Questions

What is the ZEVAC Twin used for?

The Twin is commonly used for pipeline evacuation, gas recovery, wet gas pigging, cross compression, distribution line maintenance, and trap applications. It is designed for both gas and liquid handling.

Does the Twin require electricity?

No. The system is powered by compressed air and does not require electrical power, making it suitable for remote or hazardous environments.

Can the system handle liquids?

Yes. The Twin is designed to recover product streams ranging from dry gas to 100% liquid service, including mixed-phase applications.

How portable is the ZEVAC Twin?

The unit is designed for transportation in a truck bed or trailer, allowing operators to move it efficiently between jobsites.

What is cross compression?

Cross compression removes gas from a section of pipeline being serviced and recompresses it into another section of the system, preventing product loss and reducing atmospheric emissions.

How far can the Twin draw down a pipeline?

The Twin is engineered to draw down pipelines to 0 psi, maximizing product recovery and evacuation performance.
