Compliance Verified by Design
Global Adaptability
Our modular systems comply with local pressure vessel codes (ASME, PED, or GB) to ensure seamless permitting in your specific region.
TSA Polishing (For LNG)
When Bio-LNG is required, our add-on Temperature Swing Adsorption (TSA) unit removes CO₂ to < 50ppm to prevent freezing.
High-Spec Grid Injection
Capable of meeting strict RNG interconnection rules (e.g., California Rule 30) with real-time chromatograph monitoring options.
Energy-Efficient Operation
Achieve top-tier compliance with ultra-low energy consumption (0.26 kWh/Nm³), maximizing your Carbon Intensity (CI) score.
