ENOTEC
Who is ENOTEC?

• has been founded in 1980 in Germany
• has her own R D, manufacturing and global sales
  organisation
• is focusing on non sampling InSitu analysers for
  combustion optimisation.

The ENOTEC Product Range and Applications
OXITEC True InSitu O2-Analysers from small
boilers (OXITEC ECONOMY) to large boilers
(OXITEC 5000) and special versions for high
dust applications as well as ATEX explosion
approved versions for hazardous areas (OXITEC
5000 Ex), for the operation e.g. in cement
plants, power plants and refineries.
COMTEC True InSitu O2/COe-Analysers for all
flue gases from any type of fuel, especially for
high dust applications, as well as ATEX explosion
(gas and dust) approved versions for any
hazardous area (COMTEC 6000 Ex) for the
operation e.g. in cement plants, power plants and
refineries.
CEMTEC True InSitu O2/COe-Analyser system for
high temperature and high dust areas like cement
kilns, lime stone kilns, incinerators and power
plants. Fast closed loop control of the
air/fuel-ratio and protection of the electrical
precipitator.
SYSTEC Customised process and emission analysing
systems for SO2, NOx . CH4

Blocked Measuring Tube
The CEMTEC Solution

• Mechanical cleaning by pushing every 2 minutes
  (without disruption of the measurement)
• Cleaning with compressed air every 60 minutes.

Bended Measuring Tubes
The CEMTEC Solution
Permanent turning of the probe
The probe is bended by thermal and mechanical
load.
9
CEMTEC Solutions in details (3)
Immobilisation of the Measuring Tube
The CEMTEC Solution
Clinker sticks to the probe, so that the probe
cannot be pulled out off the process any more.
Permanent turning of the probe prevents that
clinker sticks to the probe.

Defective cooling water hoses
The CEMTEC Solution
The probe cables and hoses are damaged by
friction, which can lead to a breakdown of the
measurement.
The hoses are fixed in an E-chain, so that they
cannot be damaged.
11
CEMTEC Solutions in details (5)
Defective Sampling hose
The CEMTEC Solution
With the run-in and the retract of the probe the
cables are bent again and again at their
connections. This leads to an overstraining of
the material and the break-down of the
measurement.
The hoses are fixed, so that they cannot be bent
at the connection neither at the run-in nor at
the retract of the probe.

Slow extractive Measurement
The CEMTEC Solution
Sampling hose to the analyser cabinet 15 - 20 m
The measurement is very slow, because all values
are measured by an extractive analysing system 15
or 20 m away.
The most important values are measured very fast
by the InSitu probe COMTEC 6000
