Bauer Compressors – GRU® Biogas Compressor
Quality. Our DNA.
About the Company:
BAUER COMPRESSORS, INC., headquartered in Norfolk, VA, is recognized as the world’s foremost innovative designer and manufacturer of high-pressure compressors for over 75 years. As a complete solutions provider, BAUER is a global company that operates through 21 wholly owned local subsidiaries and over 600 local distributor partners worldwide. BAUER compressors are field proven in a multitude of diverse high-pressure applications. They specialize in the markets of high-pressure breathing air, GSA/military breathing air, industrial air and gas, plastics technology, natural gas, and inert gas compression.
BAUER compressors are known around the world for their extreme durability and reliability. All BAUER compressors are backed by BAUER’s unmatched 2-year comprehensive warranty, as well as a lifetime support guarantee. Combined with BAUER’s global reach (35 offices in 20 countries, and over 600 distributors worldwide), no one in the industry can match BAUER’s dedication to supporting their customers. BAUER not only makes the most reliable and durable compressor in the world, but BAUER also designs and manufactures the entire compression solution in-house. At BAUER, they manufacture both the compressor and complete compression system, which allows them to take full responsibility for every step of the process. BAUER also has extensive experience in providing compression solutions for specifically biogas applications. To date, they have completed over 100 compressor installations in biogas upgrades, and over 2,000 successful installations in CNG applications.
About the Solution:
The BAUER GRU
Bauer Compressors has recently been added to the Newtrient catalog. Newtrient will continue to work with Bauer Compressors to further refine the cost and performance information on their technologies and services. Newtrient will update this entry as more information becomes available and as new commercial dairy installations come online.
Biogas Compressor range has been specifically designed for feeding biogas upgrading systems. The function of the biogas recovery compressor is to elevate the pressure of the incoming biogas from 1-7 psig (typical) to 90-230 psig, which is the operating pressure requirement for most PSA/membrane type gas upgrading systems. BAUER offers a complete GRU system size range from 10 HP to 750 HP (7.5-560 kW).
At the heart of every GRU® compressor system is the legendary BAUER Rotorcomp® rotary screw compressor, which is world-renowned for exceptional durability and reliability. The sophisticated control system in the GRU® senses pressure upstream of the unit, and automatically adjusts the compressor speed to modulate compressor output based on the availability of biogas from the source (landfill or digester). If there is an insufficient amount of gas available upstream for compression, the system automatically goes into standby mode for instantaneous compression capability when upstream gas pressure suddenly increases. This significantly reduces the occurrences of venting gas into the atmosphere because the compressor is ready to operate instantaneously, instead of ramping up through normal start-up sequences after being completely shut down.
Solution Strengths, Weaknesses and Critical Indicators
Anaerobic Digester Associated Technology:
NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.
- Long usable life and can be run reliably
- Creates energy and generates environmental credits
- Requires proper preparation of the feedstock
- Requires other technologies for energy utilization
- Requires other technologies for digestate handling
- Proper feeding & system monitoring is required to avoid system downtime
- Proven technology for odor control, GHG reduction and pathogen reduction
