| Compressor
Wheels |
|
|
|
|
|
| We supply all stages of compressor wheels,
specifically designed and produced for C20 engines. Genuine EXTEX wheels are longer
lasting and better performing. |
|
 |
|
|
| Stronger- |
|
| increased strength and corrosion resistance through use of Custom 450, an
advanced material developed specifically for compressor wheel applications. |
|
| Reduced erosion- |
|
| our wheels have smoother surface finishes and don’t need coatings to
mask surface imperfections; smoother surfaces reduce the potential for erosion. |
|
| Reduced downtime- |
|
| no costly coatings required: Inspections and minor blending can be
performed in your shop; no outside services required. |

| Combustion
Liners |
|
|
|
|
|
| Genuine EXTEX liners are better than the
originals, and last significantly longer. |
|
 |
|
|
| More durable- |
|
| EXTEX combustion liners are made from Hasteloy X, better and stronger than
stainless steel. |
|
|
|
| Cleaner, truer- |
|
| stronger materials mean less temperature-induced distortion, and reduced
carbon buildup/stringers. |
|
|
|
| Downstream benefits- |
|
| less temperature-induced distortion means more consistent flame patterns,
reduced nozzle distress and lower maintenance costs. |

|
|
| NOZZLES |
|
|
|
|
|
| EXTEX now offers 1st and 2nd stage nozzles for
the Allison 250 C20, C30 engine. Genuine EXTEX nozzles are not simply replacements - they
are designed and manufactured with technical improvements to give better performance and
durability. |
|
 |
|
|
| High temperature resistance- |
|
| EXTEX nozzles are made from improved IN738 material; the result is less
vane distortion, lower overhaul costs. |
|
|
|
| Resistant to erosion and corrosion - |
|
| our nozzles are treated with vapor-deposition alumide coating to further
enhance durability. |
|
|
|
| Reduced cracking- |
|
| our proprietary design incorporates thicker airfoil trailing edges and
outer bands. |
|
|
|
| Better performance- |
|
| EXTEX nozzles are designed with optimized flow area. |

|
| Gears
and Splined Parts |
|
|
|
|
|
| Parallel-ground spline teeth- |
|
 |
| and tighter tolerances result in less back-lash, greater load-bearing
capacity, more consistent fits and less wear. |
|
|
|
| Tighter tolerances- |
|
| EXTEX uses ion nitriding which yields better dimensional stability
compared to older hardening methods |
|
|
|
| Manufacturing standards- |
|
| unlike other suppliers, EXTEX uses only current technical standards, such
as AGMA 2000 for gears, and ANSI B92.1 - 1996 for splines. |
