SILOXA GRW: Effective gas conditioning
The GRW product range was designed to effectively remove organic silicon compounds (siloxanes) and hydrogen sulfide (H2S) from digester gases.
GRW - effective gas cleaning for silicon compounds (siloxanes)
The GRW conditioning systems are designed to effectively remove organic silicon compounds (siloxanes) and hydrogen sulfide (H2S) from digester gases. They utilize SILOXA’s MAKA activated carbon filters, which are designed as exchangeable filters in a deposit system, allowing for quick and clean filter changes.
Our GRW systems are not only effective, but also widely adopted, as siloxanes in digester gases can lead to increased engine wear, and also to severe engine damage in CHPs without filtration. These units are delivered fully assembled, piped, and wired on a stainless steel frame and are suitable for ground-level installation. All gas-contacting parts are made from corrosion-resistant stainless steel.
Why choose the GRW:
- Integrated shell and tube heat exchanger to reduce gas moisture
- Use of standardized MAKA exchangeable filters
- Quick exchange service
- System mounted on a corrosion-resistant stainless steel frame
- Modular design with upgrade options
