ABB ACF5000 Multi-Component FTIR Emission Monitoring System

Overview

Industry-Leading Continuous Emissions Monitoring

The ABB ACF5000 is a state-of-the-art Continuous Emissions Monitoring System (CEMS) designed for accurate, reliable, and compliant monitoring of industrial stack emissions. Based on advanced Fourier Transform Infrared (FTIR) technology, the ACF5000 provides simultaneous measurement of multiple gas components from a single sample stream, making it one of the most versatile emissions monitoring solutions available today.

With over 30 years of FTIR emissions monitoring experience and thousands of installations worldwide, the ACF5000 has become a trusted solution for power generation, waste-to-energy facilities, cement plants, chemical processing industries, and other regulated emission sources.

Advanced FTIR Technology

At the heart of the ACF5000 is a high-resolution FTIR spectrometer that continuously analyzes flue gas composition with exceptional sensitivity and stability. The system is capable of measuring up to 15 gas components simultaneously, including water-soluble compounds that are often difficult to monitor accurately using conventional analyser technologies.

Typical Measured Components

• NO and NO₂ (NOx)
• • SO₂
• CO
• CO₂
• HCl
• HF
• NH₃
• H₂O
• VOCs
• Formaldehyde
• N₂O
• CH₄
• Total Organic Carbon (TOC)
• O₂ (with integrated oxygen measurement)

Key Features

Simultaneous Multi-Component Measurement

Unlike traditional analyser systems that require multiple instruments, the ACF5000 continuously measures up to 15 pollutants simultaneously through a single sampling point, reducing installation complexity and maintenance requirements.

Hot/Wet Extractive Sampling

The proven hot/wet extractive sampling system prevents condensation and loss of water-soluble gases such as HCl, HF, and NH₃, ensuring highly accurate measurements even in challenging flue gas applications.

Lowest Cost of Ownership

The ACF5000 incorporates:

• Air-driven aspirator pump with no moving parts
• Long-life optical components
• Minimal consumables
• Reduced maintenance requirements
• Maintenance intervals of up to 12 months in certified applications

These features help minimise lifecycle costs and maximise system availability.

Automatic Validation and QAL3 Support

An integrated validation system enables automatic zero and span drift checks without the need for bottled calibration gases. This simplifies compliance with EN 14181 quality assurance requirements and significantly reduces operational costs.

Built for Compliance

As environmental regulations become increasingly stringent, the ACF5000 is designed to help operators meet present and future emissions monitoring requirements.

Compliance Support

EN 15267 certified configurations

EN 14181 QAL3 quality assurance support

MCERTS approvals

Compliance with US EPA monitoring requirements

Continuous emissions reporting capability

The latest ACF5000 LCS (Low CEMS Specialist) version has been specifically developed to support emerging low-level emissions monitoring requirements under the revised European Industrial Emissions Directive (IED 2.0).
