The ASCO DPT Control System provides superior monitoring, optimizing dust collector system performance and increasing uptime

Emerson's new ASCOTM DPT Control System optimizes the performance and improves the efficiency of filtration and dust collector systems by providing accurate and reliable low-level particulate monitoring, early warning leak detection, enhanced cleaning control, and real-time diagnostics.

The connected system is a cost-effective, scalable, and purposeful step toward a facility's digital transformation. It is available in Asia-Pacific, Europe and the Middle East, and Africa, with availability in the Americas by mid-2023.

Low-level leakage is hard to detect in environments with high operating pressure, high humidity, or oil and steam using traditional sensing technology. The advanced signal processing of the DPT Control System helps ensure accurate, low-level measurement and detection of particles.

It can catch particles less than one milligram per cubic meter in harsh, high-pressure (maximum 7 bar) and high-humidity applications, like those found in the cement, power plant, incineration, finishing aluminium, 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 more efficient and reliable dust collection system."

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 the 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 optimizes 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 the pulsing frequency, extending filter life and reducing 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 the water column of the set point while minimizing pulsing. This ensures consistent cleaning performance, maintains a good filter cake, and can reduce compressed air use by 15 percent to 40 percent over standard, on-demand cleaning and up to 90 percent 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. Learn more about the ASCO DPT Control System.
