ENOTEC – COMTEC® O2 / COe Analyzers

COMTEC 6000 is the world’s first in-situ analyzer for measurement of oxygen and combustible in flue and process gases for optimal combustion control.

The COMTEC® 6000 is an in-situ analyzer for measurement of oxygen and COe (sum of unburned molecules – CO, H2, CxHy) in flue and process gases. This enables the redundant measurement in real time for combustion fine tuning . This is achieved by combining the MXP sensor for COe analysis with the technology of MLT sensor which measures oxygen content.

Both sensors are located within the process at the tip of the probe installed directly in the flue gas duct. This allows for fast and continuous flue gas data measurement, enabling fast response rates to changes in the flue gas composition.

The analyzer was designed with low maintenance in mind, with minimal calibration requirements and user-friendliness. Furthermore high costs for investment and maintenance, especially when comparing to extractive analyzers, can be avoided.



ENOTEC – OXITEC® O2 Analyzers


Oxygen analyzers for exact, quick and durable combustion control. Confidence in measurement technology can only be created if the oxygen analysis in the combustion process is precise, the measurement is fast and the analyzer construction is robust. The OXITEC 5000 Oxygen analyzer, manufactured in Germany by ENOTEC, completely meets these requirements.

The heart of the system is the gas sensor from the ENSITU family of sensors which is lies within the probe.The in-house development and manufacturing of the sensors guarantees the highest quality and allows for permanent use in harsh process conditions such as high dust load and aggressive or corrosive flue gas compositions. A strength of the ENSITU sensors is their durability in process-induced vibrations, giving them an average life span of over 7 years.



ENOTEC – CEMTEC® Gas Sampling System

CEMTEC® has self-cleaning properties and unparalleled mechanical strength for continuous measurement for pyro process optimisation in cement plants.

The CEMTEC® gas sampling probe system was developed for continuous analysis of flue gas in cement plant rotary kiln inlets and other extremely dusty, high temperature processes such as in lime plants with the goal of increasing product quality with reduced fuel usage while simultaneously reducing harmful emissions.

Particularly in view of the increasing usage of alternative fuels in rotary kilns and large combustion chambers, the on-site gas analysis has become ever more important.
In addition, stringent emission targets in cement plants in Germany, Europe, USA and other countries worldwide necessitate continuous process measurement for SNCR control for NOx  reduction.

Process temperatures up to 1400°C, dust concentrations of up to 2000 g/, high mechanical stress and ambient temperatures up to 50°C make extreme demands on any equipment. CEMTEC®unique features provide an optimal solution for uninterrupted measurement under challenging conditions as found in kiln inlet chambers.

The CEMTEC® is self-cleaning which enables continous measurement. 95% availability of measurement during operation is reached. In addition to the in-situ sensors for oxygen and COeanalysis, extractive analyzers are supplied with  dust free flue gas for measurement of e.g. SO2, NOx or CO2.

Due to its mechanical cleaning, continuous extraction and analysis of process gas is possible over a long period of time: Theplunger at the gas inlet removes any deposits or blockages, keeping the gas inlet free. The patented swivel drive continuously rotates the probe in programmable intervals and prevents deformation of the probe tube and enables probe retraction at any time.
