CEMS Maintenance Service
Our CEMS Maintenance Service is designed to keep your Continuous Emission Monitoring System operating at peak performance, ensuring reliability, accuracy, and system stability at all times. CEMS maintenance consists of routine and corrective activities that play a critical role in preventing system downtime, avoiding measurement failures, and ensuring the validity of emission data.
Maintenance activities are performed by qualified CEMS technicians or authorized vendors with expertise in handling CEMS components and systems. The service is carried out on a scheduled basis—daily, weekly, or monthly—and can also be conducted immediately when system disturbances or performance issues occur.
Our maintenance scope covers all critical CEMS components, including probes, filters, sampling lines, analyzers, and the Data Acquisition System (DAS). The maintenance process includes probe cleaning, filter replacement, leak checks, zero–span calibration, and comprehensive system alarm verification. Through structured and professional maintenance, we help ensure continuous system availability, reliable emission data, and operational confidence for your environmental monitoring requirements.
Our Project Case Studies
Mercury Analyzer Recovery
The mercury analyzer was unable to perform measurements and displayed a “GT error” notification. Our service team replaced the gold trap, successfully restoring normal and stable measurement performance.
Flowmeter Sensor Recovery
During flowmeter verification, the readings were found to be outside the specified range. An indication of diaphragm damage was identified, and the sensor was replaced to restore normal and stable flowmeter performance.
Gas Pump Replacement
The sample gas pump was damaged and no longer able to operate to draw sample gas from the probe located above the chimney. A pump replacement was performed to restore proper sample gas extraction and ensure normal system operation.
Sampling Hose Replacement
An anomaly was detected in the analyzer readings. Upon inspection of the sampling system, damage was found on the peristaltic pump hose, which was torn and required replacement to restore normal analyzer performance.
UFO Filter Replacement
The mercury analyzer’s UFO filter had reached the end of its service life and required replacement to maintain reliable and accurate measurement performance.
PLC Module Replacement
A lightning strike caused damage to the PLC AI/AO module. The damaged PLC module was replaced to restore normal system functionality and reliable operation.
SO₂ Detector Replacement
An abnormal SO₂ inlet reading showing a value of (****) triggered a fault alarm. Further inspection revealed detector saturation, requiring detector replacement to restore normal and reliable measurement performance.
