Emisense Technologies Unveils Affordable ePM Sensors for Enhanced Air Quality Compliance

Emisense Technologies, LLC has made a significant move in air quality management with the recent launch of its electrostatic PM (ePM) sensors, tailored for large diesel generators utilized in critical areas such as data centers and hospitals. This innovative technology aims to ease the burden of adhering to stringent Tier-4 emissions standards, which have become essential for operators looking to either implement new generators or upgrade existing ones.

The Challenge of Compliance

Patrick Thompson, CEO of Emisense, emphasizes the pressing need for operators to extend the operational capabilities of emergency backup generators. "Going beyond strict emergency conditions necessitates compliance with more rigorous Tier-4 emissions standards," he states. This challenge becomes paramount in sectors where air quality regulations are growing increasingly strict, compelling operators to look for effective solutions to meet these standards without incurring significant costs.

Accelerating Calibration and Integration

With this in mind, Emisense’s introduction of low-cost continuous monitoring solutions is a game-changer. The technology not only simplifies pre-certification testing but also facilitates the evaluation of retrofit components, such as Diesel Particulate Filters (DPFs). It allows operators to ensure energy availability during critical situations, whether responding to emergencies or capitalizing on profitable demand response programs.

Furthermore, the ePM technology boasts compatibility with various fuel types, including diesel, natural gas, and multi-fuel options. As the reliance on internal combustion engines persists, ensuring that these generators achieve the lowest possible emissions is a priority that Emisense addresses with their ePM sensors.

Advantages of ePM Technology

The ePM sensors are specifically designed for in-situ stack applications. Notably, the total system costs for these monitoring devices are less than 1% of the generator’s value, making them an economically viable option for many operators. Among the key benefits are quicker response times, enhanced sensitivity, and a continuous signal. These advantages position the ePM technology as superior to traditional delta-P methods, which measure exhaust pressure as a proxy for particulate matter measurement.

In addition to PM monitoring, these electrostatic sensors, known under the trade name PMTrac®, can be integrated with NOx and other pollutant sensors. This setup enables cloud-based, continuous monitoring of all criteria pollutants, thus promoting more informed management decisions while reducing compliance costs through improved integration, sensor self-diagnostics, and diminished maintenance expenses.

Expanding Horizons

As Emisense prepares to expand its technology beyond the automotive sector, they are keen to engage with additional markets that can benefit from their monitoring solutions. The promise of large stationary applications represents a strategic opportunity for growth in this area.

Emisense is based in California and collaborates with institutions like the University of California, Riverside, and the Southwest Research Institute to validate the performance and durability of their PMTrac® ePM technology. Their commitment to advancing air quality through innovation and technical excellence is commendable.

For operators and stakeholders in critical energy and health sectors, the arrival of Emisense’s affordable ePM sensors could redefine how compliance is managed in the context of stringent air quality regulations. With these advancements, the path to cleaner and more efficient energy generation appears more attainable than ever.
