Chimney and cooling tower design
Nyeleti designs chimneys and cooling towers according to relevant national and international standards and code requirements.
Chimney inspections
Flue inspections are done from the inside of the flue by using our high-intensity infrared video camera system. This system consists of a 360° camera view and can zoom in at any defect to assess the extent of a damaged area at any position. The inspection is recorded and forwarded to the client. Specialized services include the following:
- Internal inspections
- Structural integrity prediction
- Structure lifetime predictions
- Remedial actions
- Damage assessment
- Stress analysis
- Structural and thermal dynamic analysis
- Cost of repairs
- Project management
- Material assessment specifications.
Ground probing radar investigations
Ground Penetrating Radar (GPR) offers an accurate, non-destructive solution to mapping the subsurface of the earth to find subsurface features such as pipes, cables, rocks, holes, etc. With Nyeleti’s GPR antennas, it is simple to locate features of interest and subsurface layers in real time. Capabilities by using GPR include the following:
- Concrete inspection
- Utility locating
- Road inspection
- Bridge inspection
- Environmental assessment
- Ice and snow
- Agriculture and forestry
- Mining
- Railway evaluation
- Forensics
- MATERIAL SCIENCE

EXXARO GROOTGELUK
Laser scanning captures spatial data by the use of Laser light. The Shape, position, and spatial locations of objects are recorded by millions of points. From this complete data set a 3D as-build model can be constructed using the appropriate CAD (Computer aided drafting) programs with an accuracy of less than 3mm.
