Evidence Notes
Biogas cooler-dryer conditioning architecture
Raw digester gas brings saturated moisture and trace H2S into the analyzer front end. The v1 architecture uses a controlled Peltier cooler, coalescing filtration, and automatic condensate removal to separate liquid carryover before the analyzer inlet.
Cool-dry boundary for reactive gases
Cool-dry conditioning is a fit for clean, non-reactive gases; water-soluble or reactive compounds require dry-basis correction or a heated sampling review to avoid analyte loss in condensate.
Technical & Engineering Details

01 Operating Envelope
Use these limits as selection inputs, then confirm sample condition, ambient exposure, and materials before quotation.
- Non-corrosive process gases
- Mildly corrosive gases with application review
- SS316L
- Borosilicate glass
- PTFE
- Highly corrosive HCl, HF, or SO3 duty; use heated sampling with appropriate wetted materials
- Inlet gas above 60 C without a pre-cooler
- Water-soluble gases such as SO2, NH3, or HCl without dry-basis correction or heated sampling review
02 Maintenance & Spares confirmed
Tasks, consumables, and access items are shown only when structured maintenance data is available.
- Replace or inspect the 0.5 µm coalescing filter based on aerosol loading
- Check peristaltic condensate drain operation and trap level during service rounds
- Verify Peltier setpoint and high-temperature alarm relay after installation changes
- Review gas solubility before applying cool-dry conditioning to SO2, NH3, or HCl streams
- Coalescing filter element
- Condensate drain service parts
Compact wall-mount enclosure with LED status and condensate trap access
03 Application Evidence
Application context from complex industrial environments.
Application Context
Biogas upgrading facilities conditioning raw digester gas saturated at 38 °C with 2,000 ppm H₂S need cooler-dryer architecture before the analyzer, because moisture and trace H₂S together accelerate sample-cell degradation.
Architecture Response
GS-SCS-600 with <5 °C dew point and a coalescing filter removes condensate carryover by design, supporting extended analyzer sample-cell service life across digester-gas duty cycles.
Frequently Asked Questions
What is the difference between cool-dry and heated sampling?
Cool-dry removes moisture by cooling below dew point — ideal for clean, non-reactive gases. Heated sampling maintains temperature above dew point — required for corrosive or reactive gases (HCl, SO₃, NH₃) that would be absorbed by condensate.
Can it handle corrosive gases?
The GS-SCS-600 is designed for non-corrosive to mildly corrosive gases. For highly corrosive streams (HCl, HF, SO₃), use the GS-SCS-800 heated system with Hastelloy wetted parts.
What happens to the removed condensate?
Condensate drains automatically via a peristaltic pump to a collection vessel or floor drain. The 250 mL internal trap provides buffer capacity during high-moisture conditions.
How precise is the dew point control?
The PID-controlled Peltier cooler maintains dew point within ±0.5°C of the setpoint. Adjustable from 2°C to 10°C to optimize for different gas compositions.
Does cooling affect gas measurement accuracy?
For most gases (CO, CO₂, O₂, CH₄), cooling has negligible effect. For water-soluble gases (SO₂, NH₃, HCl), use dry-basis correction or heated sampling to avoid analyte loss in condensate.
