Technology and Design
The INCA analyzer consists of a fully integrated measurement unit where all critical components — sensors, pumps, valves, and control electronics — are mounted on a single carrier plate. Communication between modules occurs through an internal device bus, ensuring stable operation and straightforward maintenance.
Key modular elements include:
- Sample gas supply and conditioning modules
- Sensor modules (NDIR, electrochemical, paramagnetic, thermal conductivity)
- Gas cooler options for condensate removal
- Control and data processing unit with digital outputs
The modular approach allows future upgrades and replacements without redesigning the entire system — a cost-efficient solution for long-term operations.
Key Benefits for You
- Tailored to your application: Modular build adapts to biogas, natural gas, syngas, or by-gas measurement
- Flexible performance: Expandable sensor configuration and scalable system capacity
- Cost-efficient operation: Standardized modules reduce service time and spare-part needs
- Proven technology: Thousands of units installed globally across the gas industry
- Future-ready design: Easy retrofitting or upgrades without complete replacement
Typical Applications
- Biogas and biomethane plants – Optimize methane yield and upgrade quality
- Natural gas and syngas systems – Analyze composition for combustion and energy value
