A Stack Emission Monitoring System, also known as Continuous Emission Monitoring System (CEMS), is a sophisticated technology that continuously measures and records pollutant emissions from industrial stacks and chimneys, ensuring compliance with environmental regulations.
CPCB mandates CEMS for thermal power plants, cement plants, chemical industries, pharmaceutical units, textile dyeing facilities, waste incinerators, and any industry with significant air emissions as per environmental clearance conditions.
Drexel CEMS can monitor: SO2, NOx, CO, CO2, O2, HCl, HF, VOC, TOC, Particulate Matter (SPM/PM), temperature, pressure, flow velocity, and moisture - all simultaneously in real-time.
Our systems maintain ±2% measurement accuracy for gaseous pollutants and ±5% for particulate matter, exceeding CPCB and EPA accuracy requirements.
Extractive CEMS extracts gas samples from the stack for analysis in a controlled environment, offering higher accuracy. In-situ CEMS measures directly in the stack, providing faster response. Drexel specializes in extractive systems for maximum precision.
Typical installation and commissioning takes 2-4 weeks depending on stack configuration, site conditions, and customization requirements.
Yes! Drexel offers comprehensive Annual Maintenance Contracts (AMC) including quarterly calibration, spare parts, remote support, and emergency services.
Absolutely! Drexel specializes in retrofitting and upgrading obsolete or underperforming CEMS with modern technology, calibration units, and CPCB connectivity.
We provide 1-year comprehensive warranty covering all components, performance guarantee, and free calibration services. Extended warranties available.
Drexel CEMS features built-in IoT modules that automatically transmit emission data to CPCB/SPCB servers every 30 minutes via secure internet connection or mobile network.
Drexel Electronics and Engineering Products Pvt. Ltd. combines 35+ years of engineering excellence with cutting-edge emission monitoring technology to deliver CEMS solutions that protect the environment and ensure regulatory compliance.
