ABB has extended its range of continuous emissions monitoring systems with the launch of the ACF5000 for combustion applications. Using FTIR technology, the ACF5000 enables accurate measurement of exhaust gases through the simultaneous analysis of up to 15 different gas components including SO2


The ACF5000 combines the advantages of an FTIR (Fourier Transform Infra-Red) spectrometer with zirconia oxygen measurement and optional flame ionisation (FID) technology. The high resolution FTIR spectrometer performs sensitive and stable measurement of active gas molecules, ensuring highly accurate quantification of gas components. Where the FID module is included, the ACF5000 can also be used to measure unburned hydrocarbons at ppm levels to help improve combustion efficiency.


The ACF5000’s proven hot / wet extractive measurement technology removes the need for sample dilution, enabling it to provide accurate measurement of oxygen levels of up to 25 percent of the sample volume.


Further accuracy can also be achieved by using an optional blow-back unit, which enables uninterrupted measurements in high dust applications.


Completely self-contained, the ACF5000 offers a turnkey combustion process monitoring solution suitable for municipal, industrial and hazardous waste incineration and power plants using coal, oil or waste. The system offers a small footprint, opening up new possibilities for installation in confined spaces. This is achieved by the use of a single sample inlet for all sample gases, together with a stream switching function that allows for monitoring of two streams sequentially.


The ACF5000 has been designed to minimise operating and maintenance costs. Its modular design enables it to be easily upgraded to meet changing requirements when adding extra equipment such as the optional FID module.


Additional features include an in-built validation unit, which uses internal references to enable cost effective monitoring and validation of the FTIR spectrometer. Films and gas cells for all FTIR components are used as a surrogate for test gases, eliminating the expense associated with using test gas cylinders. By enabling on-going system validations, the validation unit satisfies BS EN 14181 QAL3 requirements for maintaining and demonstrating the performance of CEM systems during normal operation.


Further operational savings are achieved by the inclusion of a maintenance-free injector pump for passing gas samples through the system. Expanding the ACF5000 to handle additional gas measurements is also simple. Where extra IR-components need to be added, the ACF5000 can be readily upgraded on-site with new software, minimising disruption.


For added security, the ACF5000 enables operators to remotely monitor the system from an external PC or control system, with diagnostics, configuration and maintenance data, including QAL 3 quality data, automatically being relayed via Ethernet, Profibus or Modbus.


The ACF5000 is certified to relevant leading standards, including EN 14181 QAL1, QAL2 and QAL3 and is MCERTS certified for use in process plants for applications including DeNOx and DeSOx plant optimization and HCL scrubber monitoring.


ABB has been a pioneer in FTIR CEMS systems since 1993 and has over 20 years’ experience in the design, manufacture and supply of FTIR spectrometers for process gas analysis applications. For More Info, email:

New Series of Wall-Mount Particle/Mass Monitors Offers Wide Array of Measurement Options


email: For More Info, email: email:


GrayWolf Sensing Solutions have introduced a new, branded 6-channel Particulate Meter which optionally incorporates sensors for additional environmental parameters such as Total Volatile Organic Compounds,Carbon Dioxide, Temperature and Relative Humidity. The wall-mounted monitor, an updated version of GrayWolf’s PC-4005, which was launched in 2016, displays and logs calculated particle mass concentrations whilst simultaneously displaying and logging all installed optional sensors.


A long-life, laser diode powered sensor and a precision brushless internal pump enable reliable particulate measurement


down to 0.3 microns. A high accuracy photo-ionisation detector (PID) for TVOC measurement and a dual-wave NDIR CO2


sensor, both optimally


suitable for IAQ applications, are offered. The PC-5000 series monitors may alternatively be connected to GrayWolf’s AdvancedSense® WolfPack®


, DirectSense® or instruments to add additional parameters (e.g. formaldehyde,


ozone, carbon monoxide, nitrogen dioxide, ammonia and more) logging into the same data file as other connected sensors. This also allows the user to take full advantage of the broad range of features offered by GrayWolf such as on-board educational info including help videos, IAQ particle size charts, government/industry particulate guidelines and more.


The PC-5000 Series Wall-Mount Particle/Mass Monitors may integrate into a building automation system using Ethernet, USB, RS232 or the optional wireless 802.11 b/g or RS485. Access readings via Modbus RTU or optional cloud-based GrayWolfLive™. PM1.0, PM2.5, PM10 and other particle mass size ranges may be concurrently displayed and logged. These monitors measure particle sizes from 0.3 µm to 25 µm with a flow rate of 2.83 LPM (0.1 CFM). Display 6 particle count size ranges simultaneously; 0.3µm, 0.5µm, 1.0µm, 2.5µm, 5µm, 10.0µm are standard. Alternative size “binning” is available as an option.


Detailed report generation has never been more efficient. The PC-5000s are supplied with GrayWolf’s WolfSense®

A Reliable, Continuous Pump For Continuous Emission Monitoring Systems Emissions


ContinuousEmissions Monitoring Systems (CEMS) play a hugely important role in environmental protection. Stack and exhaust emissions are subject to a variety of stringent, regional regulations which need to be adhered to. The THOMAS 1610 AC vacuum pump from Gardner Denver fulfils all of the necessary requirements that need to be met by a CEMS in industries that need to ensure they are complying to their local environmental legislation. It distinguishes itself through continuous operation and excellent performance stability throughout its lifetime thus facilitating accurate fume and emissions monitoring.


The maintenance free operation, long lifetime and stable performance of the 1610 AC pump ensure that users are given outstanding durability and reliability. This pump has a long life span due to its configuration. Operators do not need to break any molded inlet or outlet ports as the 1610 has threaded ports. Gardner Denver have incorporated FKM elastomers in the pump to ensure chemical compatibility and the pump’s efficient heat extraction means that users can enjoy reliable, continuous operation.


The 1610 AC vacuum pump, especially when combined with Gardner Denver’s SR25 peristaltic pump, is perfect for use for gas detectors and collectors. It can be used in a wide range of locations such as large combustion and incineration plants, for cement, lime, kilns etc.
