Dhaka, Bangladesh — RotoTech Bangladesh Limited, a pioneer in engineering solutions, has made headlines with its remarkable success in refurbishing a critical turbocharger component for Desh Energy Chandpur Limited. The A175-M66 nozzle ring, part of the Wartsila W50V20DF engine, had been plagued by premature cracking and deformation after 10,000–15,000 hours of operation, leading to serious operational challenges.
A Critical Component in Crisis
The A175-M66 nozzle ring is integral to the performance of turbochargers, and its degradation had far-reaching consequences. Engine performance was significantly compromised due to:
Lower Turbocharger RPM: Deformations reduced aerodynamic efficiency.
Higher Temperatures: Uneven vane profiles hindered heat transfer.
Decreased Charge Air Pressure: Insufficient air resulted in poor combustion, negatively affecting fuel consumption.
These issues posed threats to efficiency, reliability, and fuel economy, creating an urgent need for refurbishment.
