HORIBA ENDA-5000 Series Stack Gas Analysis System

Reliable, Multi-Component CEMS for Continuous Emission Compliance

The HORIBA ENDA-5000 Series is a superior continuous emission monitoring system (CEMS) designed to deliver stable, high-precision measurements of up to five critical exhaust gases simultaneously: NOx, SO₂, CO, CO₂, and O₂. Engineered for demanding industrial environments, this system combines field-proven cross-flow modulated NDIR technology with a compact, user-friendly design, ensuring seamless compliance with environmental regulations such as the EU Industrial Emissions Directive (IED).

Key Benefits

• Zero-Drift Stability: Utilizes HORIBA’s proprietary cross-flow modulated NDIR technology, eliminating the need for optical alignment and ensuring exceptional zero-point stability over long periods.

• Regulatory Compliance: Fully certified (QAL1/EN 15267) for continuous emission monitoring, providing peace of mind for reporting to environmental authorities.

• Low Cost of Ownership: The magneto-pneumatic O₂ sensor uses ambient air as a carrier gas, removing the need for auxiliary gas cylinders and significantly reducing operational costs.

• Intuitive Operation: Features a large, high-visibility touch panel interface that simplifies calibration, maintenance, and data review for plant operators.

• Robust Sample Conditioning: Integrated efficiently with a comprehensive sampling system to handle tough process conditions, minimizing downtime due to moisture or particulate contamination.

Technical Overview

The ENDA-5000 Series sets a new standard for stability in stack gas analysis. Its core strength lies in the Cross-Flow Modulated Non-Dispersive Infrared (NDIR) detection method. Unlike single-beam systems that drift with temperature changes or source aging, this technique alternately introduces sample gas and reference gas into the same measurement cell. This modulation creates a continuous zero-correction mechanism, rendering the analyzer virtually immune to zero drift.

System Highlights:

• Multi-Gas Capability: Simultaneously measures NOx, SO₂, CO, and CO₂ via NDIR, and O₂ via a magneto-pneumatic detection method (which avoids sensor corrosion common in paramagnetic cells).

• Interference Correction: Advanced algorithms and optical filtering automatically compensate for cross-interference from co-existing gases like water vapor or high concentrations of CO₂.

• Data Management: Built-in USB functionality allows for easy export of 1-minute, 1-hour, or daily average values, simplifying compliance reporting.

• Compact Footprint: The optimized cabinet design requires significantly less floor space than traditional CEMS racks, making it ideal for retrofits in tight plant rooms.

Typical Use Cases

This analyzer is specifically engineered for stationary source emission monitoring across a wide range of heavy industries. It is particularly effective in processes with combustion exhaust where regulatory limits are strict.

• Power Generation: Continuous monitoring of gas turbines, coal-fired plants, and biomass boilers.

• Waste-to-Energy: Compliance monitoring for municipal and hazardous waste incinerators.

• Industrial Boilers: Emission control for large-scale steam generation in chemical and petrochemical plants.

• Metal Processing: Exhaust analysis in steel manufacturing, sintering plants, and furnaces.

• Cement & Glass: Process optimization and compliance reporting for high-temperature kilns.

Why Choose This Analyzer?

The HORIBA ENDA-5000 stands out not just for its accuracy, but for its operational robustness. While many analyzers struggle with the harsh realities of industrial stacks—vibration, dust, and temperature shifts—the ENDA-5000’s modulation technology inherently cancels out these variables. For plant managers, this translates to fewer calibration cycles, less instrument downtime, and a lower risk of non-compliance penalties. It is a "install and forget" solution for critical environmental monitoring.
