DUST & FUME EXTRACTION
ADVANCED DUST PULSE TECHNOLOGY CONTROL SYSTEM
accurate and reliable low-level particulate monitoring, early warning leak detection, enhanced cleaning control and real-time diagnostics. The connected system serves as a cost- effective, scalable and purposeful step toward a facility’s digital transformation. It is now available in Asia-Pacific, Europe and Middle East and Africa regions, with availability in the Americas by mid-2023.

merson’s new ASCOTM DPT Control System optimises the performance and improves the efficiency of filtration and dust collector systems by providing
more efficient and reliable dust collection system.”
Using traditional sensing technology,
low-level leakage is hard to detect in environments with high operating pressure, high humidity or oil and steam. The advanced signal processing of the DPT Control System helps ensure accurate, low-level measurement and detection of particles of less than one milligram per cubic meter in harsh, high- pressure (maximum seven bar) and high-humidity applications, like those found in the cement, power plant, incineration, finishing aluminum and chemical industries. “The digital transformation of the process industry is underway and connected facilities around the world are seeing the valuable sustainability and operation cost reducing benefits that real-time monitoring and diagnostics deliver,” said Stephan Cocciardi, director of marketing and global strategic accounts with Emerson’s discrete and industrial business. “The sophisticated monitoring capabilities of the ASCO DPT Control System can help facilities detect issues and prevent problems that would otherwise waste energy and accrue unplanned downtime, resulting in a
By closely monitoring dust collector systems in real time, the DPT Control System can help users locate and address leaks before they become issues, improving energy efficiency and compressed air consumption savings. The loop-powered sensor enables intrinsically safe monitoring of difficult-to- access points of the filtration system, including coil, diaphragm and filter bag. The system’s condition monitoring and predictive maintenance capabilities can improve system reliability and efficiency while reducing maintenance costs and unplanned downtime. Its superior linear output can help users track real-time particle emissions levels and meet emissions regulations. In addition to monitoring, the DPT Control System optimises the performance and uptime of dust collector systems of all sizes through efficient and reliable pulse-jet filter cleaning control. For facilities that use large baghouses, application-specific control algorithms can reduce pulsing frequency, which can extend filter life and reduce the amount of compressed air consumed. The control logic can maintain quite low and stable differential pressure during operation and automatically maintains differential pressure within ±25 Pa (±0.1 inch) of water column of set point while minimising pulsing. This ensures consistent cleaning performance, maintains a proper filter cake and can reduce compressed air use by 15 per cent to 40 per cent over standard, on- demand cleaning and up to 90 per cent over continuous. It also helps ensure consistent airflow to maintain production, ventilation and dust recovery. The system provides extensive general filter pulse jet cleaning control modes, such as easily selectable pulsing patterns and a full range of basic timing modes. Modes include continuous, high/low, single cycle and cycle down. The complete DPT Control System solution includes the DPT P150 Particle Monitor, DPT P151 Controller and P152 DPT Particle Sensor.

FUME EXTRACTION FOR POTENTIALLY EXPLOSIVE ENVIRONMENTS
A xair has
announced that its S50
polypropylene fans; the
largest and most powerful fans in the company’s ‘S’ range, manufactured by SEAT, are now available in ATEX suitable for zone 2 gas environments.
Responding to increased demand, the ATEX S50
fans have been designed to remove fumes from highly corrosive or toxic environments where there is a risk of fire or explosion. They can achieve airflows of 5000 to 16,000 m3
/h and provide high air flow against medium
system pressures. ATEX S50 corrosion resistant fans are supplied with EEx nA (nonincendive) motors. SEAT is the leading EU manufacturer of plastic fans with more than 35 years’ experience in their field. As the exclusive UK distributor for SEAT, Axair is proud to work closely with the fan manufacturer to deliver superior corrosive fume, chemical, ATEX and specially designed fan components to the UK market.
The ATEX S50 is supplied with an inverter as standard, benefitting from an easy stop/start function and enhanced speed control which allows for efficient energy consumption. The molded carbon loaded polypropylene prevents static discharges and is a corrosion resistant material which can withstand harsh chemical environments and adverse weather conditions. It holds many benefits over GRP and stainless steel materials. Axair’s team has undertaken extensive training in ATEX regulations and the company has a duty of care to ensure the supply of a suitable fan based upon a customer’s correct ATEX coding specifications. ATEX has to be understood as an ever evolving subject requiring competence and training that is now provided by UK notified bodies and consultancies. Axair advises that if anyone requires additional training in ATEX that they contact an independent body for assistance.
