COMPRESSION BOOST FOR YOUR INDUSTRY
OPEN IMPELLERS
Rotor is the heart of any compressor or turbocharger. It is a center of the suction. Close attention to design of blade angles at inlet and outlet is necessary, as these are major parameters affecting power production. We understand how important it is to have a perfect surface to avoid cavitation in the high speed rotation. This is why CNC TVAR produces impellers by high precision CNC machining from a mono-block forgingg. The impellers are made from Aluminium, Stainless Steel or Titanium depending on the type of compressor and conditions in which the compressor operates.
MONOBLOCK OR SPLIT VERSION MACHINING
CLOSED IMPELLERS
Rotor is the heart of any compressor or turbocharger. It is a center of the suction. Close attention to design of blade angles at inlet and outlet is necessary, as these are major parameters affecting power production. We understand how important it is to have a perfect surface to avoid cavitation in the high speed rotation. This is why CNC TVAR produces impellers by high precision CNC machining from a mono-block forging or as a split version ready for welding. The impellers are made from Aluminium, Stainless Steel or Titanium depending on the type of compressor and conditions in which the compressor operates.

Manual polishing
Grinding and polishing – thatʼs where the parts get their final touch. When it comes to the surface quality of complex shapes, we do not make any compromises.
- Polishing based on CMM measurement report
- Experienced employees polishing according to customer specific procedures
- Several dimensional and quality controls through process
- Compliance with all environmental standards thanks to the newest filtering technologies
Non-destructive testing
Completed products are checked using four non-destructive testing methods (NDT). Our inspectors are ISO 9712level II certified.
- Visual Testing (VT)
- Liquid Penetrant Testing (PT)
- Magnetic Particle Testing (MT)
- Ultrasonic Testing (UT)

3D measurement
The measurement is performed on CMM or with a 7-axis high speed 3D arm with a laser scanner with extreme precision according to the highest international standards.
- Measurement of drawing dimensions
- Measurement of hydraulic profile
- Part alignmenet based on RPS points
- High data quality
