Stage II Vapor Recovery Equipment

Stage II vapor recovery equipment is a critical environmental protection system installed at the dispenser level of retail fuel stations. It is designed to capture volatile organic compounds (VOCs) released during vehicle refueling, preventing fuel vapors from escaping into the atmosphere.

A key component of this system is the Vapour Recovery Nozzle, also known as a Recovery Nozzle, which collects fuel vapors during gasoline dispensing and returns them safely back to the underground storage tank through a closed-loop recovery system.

Unlike Stage I vapor recovery systems, which recover vapors between tank trucks and underground storage tanks, Stage II systems focus on dispenser-side vapor recovery, enabling precise control of the vapor return process while enhancing operational safety and customer experience.

Main Components

Vapour Recovery Nozzles (Recovery Nozzles)

Coaxial vapor recovery piping

Coaxial breakaway couplers and adapters

Vapor flow meters and liquid level control devices

Vapor recovery vacuum pumps, vapor-liquid separators, and monitoring sensors

These components operate together to accurately manage vapor flow. The Recovery Nozzle plays an essential role by creating a sealed connection between the vehicle fuel tank and the dispenser, allowing vapor to be efficiently recovered while maintaining smooth fuel delivery. The complete system reduces evaporative losses, prevents vapor mist release, and ensures safe and efficient refueling operations.

Key Advantages

High Efficiency and Environmental Protection

Closed coaxial piping combined with vacuum-assisted recovery technology enables vapor recovery efficiencies exceeding 95%, significantly reducing VOC emissions. The design of the Vapour Recovery Nozzle ensures effective vapor capture during every refueling cycle, improving recovery performance and environmental compliance.

Complies with vapor recovery and environmental regulations in California, the European Union, and other regulated regions.

Safety and Reliability

Integrated pressure control, liquid level detection, and overfill protection systems help prevent vapor backflow and leakage.

High-quality Recovery Nozzles feature durable sealing structures, reliable shut-off mechanisms, and corrosion-resistant materials to maintain safe operation under frequent daily use. Corrosion-resistant materials and high-pressure piping ensure long-term stable operation and reduced maintenance risk.

Easy Integration and Maintenance

Compatible with various fuel dispenser models, suitable for both new installations and retrofit projects.

Modular design allows for easy on-site maintenance and periodic inspection, ensuring high system availability.
