Industries served

Serving the Biogas & RNG industries

Biogas, be it from organic or animal waste (biomass) in an anaerobic digester or from municipal solid waste or wastewater sources, needs to be upgraded to be useful. No matter your process and the application behind it, we can support your operational with our portfolio of biogas compression solutions. We help you get the gas to the right pressure at the best efficiency up to the grid injection point or your customer's dispenser.

Description

Did you know?

The GG oil-lubricated screw compressor offers robust compressor design for long service life. Putting superior shaft seal design and unparalleled precision manufacturing to work for you, GG-Series compressors ensure top performance year after year. They are an optimal solution for the high demands of biogas upgrading and gas grid applications.

Efficiency

Designed for High Efficiency

Atlas Copco's VSD technology closely follows the gas demand and continuously adjusts the motor speed, resulting in energy savings. The Variable Speed Drive (VSD), coupled with inlet pressure control, maximizes flow, and minimizes required horsepower.

 

By working less to do more, VSD consumes less power, while giving greater process control and requiring less maintenance. Variable  Speed  Drive (VSD) allows  your  gas  compressor  to  easily  adapt  to  changing  gas  production  needs.

 

When  the  quantity  of  gas  available from your process rises, the VSD motor speeds up to ensure a continuous supply of gas to the grid with very low-pressure fluctuations. 

Energy recovery

Even Greener with Energy Recovery​

Turn your compressor into an energy source.

Our water-cooled gas screw compressors can be equipped with an Energy Recovery unit. This helps you achieve your low carbon economy goals. 

Recover up to 75% of the electrical energy which is converted into compression heat. This can be then used by our energy recovery system to heat up water for sanitary purposes, space heating, or process applications. Considered as a key savings in Biogas where biodigester needs to be always kept warm. 

Benefits

Technical benefits

Plug, play and display

The GG units are tested in our factory, synchronized with our system, will visualize your energy savings strategy, and create transparency in your environmental reporting.  

  • Guarantees seamless interaction and ease integration. 
  • Monitoring system SmartLink enables you to always know the status of your compressor 
  • Accessible connections for water, gas, and power.  
  • Easy installation and Ready for use. 
Low cost of ownership
By implementing gas screw technology and VSD drive, the GG-Series offers you tremendous savings in terms of energy and maintenance. Well-designed circuits, full accessibility and the capability for predictive maintenance also contribute to a low cost of ownership for your machinery. 
Gas-tight and secure
Equipment for gas compression must meet more stringent safety requirements than conventional air compressors. The GG-Series measures up: 100% gas-tight and in compliance with ATEX Zone 2 

Biogas and biomethane compressors

Combining outstanding performance and safety in a compact, cost-efficient package, our GG-Series compressors meet the demands of the most rugged Biogas and biomethane gas grid injection facilities. Powered by Variable Speed Drive (VSD) technology, GG-Series compressors do not only help reduce power bills, but also significantly lower the wear-and-tear on your compressor. That, in turn, reduces your maintenance cost and service intervals 

Safety

Optimal control and safety

An easy-to-use control system – the Elektronikon Mk V control & monitoring system, allows you to keep an eye on all parameters of your daily operations. Moreover, key features including an emergency solenoid valve shutdown stop to isolate the compressor from the gas supply in emergencies.

In addition, gas detection sensors and software, allow for a safe compressor solution. With a compact and robust design to meet the high safety demands in the biogas industry, the GG-Series compressors comply with the stringent ATEX 2 design requirements and CE directives.

Security functions are handled by a SIL2 PLC (according to IEC 61508), making the GG-Series one of the safest and most reliable choices in the industry.
