The ABB SCC‑C 23070‑103112200000 Sample Gas Cooler is a core device developed by ABB Measurement & Analytics, specifically designed for analytical applications. It belongs to the SCC‑C series and is available in standard and explosion‑proof versions (suitable for Zone 2 or Class I, Division 2 hazardous areas).
Its key function is to reduce the dew point of humid sample gas and prevent condensation inside the analyzer. Meanwhile, it provides stable low‑dew‑point output to minimize cross‑sensitivity to water vapor and volumetric errors, offering precise and reliable pre‑treatment support for gas analysis.It is widely used in various industrial gas detection, environmental monitoring, and other applications that require high‑precision gas analysis.

Installation and Maintenance
1. Installation Instructions
Before installation, place the unit in operating position for approx. 24 hours to allow oil in the refrigeration circuit to flow back to the compressor.Install with sample gas connections facing upward to prevent oil migration during transport.Install close to the gas analyzer to minimize line length, ensure sufficient ventilation, and keep away from heat sources, dust, strong drafts, corrosive environments and vibration.Observe sample gas inlet and outlet markings (arrows on heat exchanger). For glass heat exchangers, check PTFE/silicone clamping rings. PVDF and stainless steel heat exchangers use tapered R-threads per DIN 2999/1 with sealing tape/sealant.For electrical connection: first connect protective earth (PE). Install a max. 10 A circuit breaker and accessible main switch. Separate signal and power cables; use copper cables only.
2. Routine Maintenance
- Replacement Parts:
- Hose pump tubing: replace every 5 months (Order No. 90P1007)

3. Troubleshooting
Common issues include abnormal condensate drainage (hose pump failure or line blockage), insufficient cooling (dirty condenser or poor airflow), abnormal temperature display (temperature controller fault or refrigerant leakage). Refer to the “Diagnostics/Troubleshooting” section of the manual for fault-cause-remedy procedures. For complex faults, contact ABB customer service.
System Compatibility
The ABB SCC‑C 23070‑103112200000 Sample Gas Cooler is compatible with many ABB analysis systems. The key matched product is the SCC‑F Sample Gas Feed Unit, which provides condensate monitoring, sample gas feeding, flow adjustment and monitoring. Combined with SCC‑C, they form a complete sample gas pre-treatment system.If a temperature alarm occurs on the SCC‑C, the diaphragm pump in the SCC‑F shuts down automatically to enhance system safety.The cooler integrates seamlessly into all ABB gas analyzer systems, supplying stable, dry sample gas.
