Overview
Product Details
The HX55W turbocharger is a next‑generation heavy‑duty turbo platform engineered for heavy‑duty trucks and construction machinery. It delivers class‑leading boost response, stable pressure output and export‑ready reliability for fleets and repair shops for replacement and upgrade.
Designed around mature turbocharger development experience, the HX55W integrates precision aerodynamic design, high‑strength material and proven bearing‑sealing technology to help operators reduce total maintenance cost while maintaining strong performance under heavy‑load.
Product Advantages
Strong Boost Performance
- Excellent low‑speed boost response for large‑displacement WP12 diesel engine
- Sufficient air flow supply for full‑load climbing and overloading operation
Intelligent & Stable Operation
- Wastegate actuator accurately regulates boost pressure to avoid over‑boost
- Optimized flow path structure effectively suppresses compressor surge
- Sustained stable power output during long‑duration continuous operation
Safe and Reliable
- High‑temperature resistant turbine wheel coping with high exhaust temperature
- Optimized bearing‑sealing assembly reduces risk of oil leakage
- Strict full‑scale dynamic balance testing to extend service life
