MAN Energy Solutions said its new Axial TCT turbocharger series is optimized for Tier 3 operation and is suitable for both conventional and dual-fuelled, two- and four-stroke engines.
The TCT series has been introduced to accompany and eventually replace the TCA generation. The TCA’s design has been regularly updated since its introduction, but is now some 15 years old. With TCT turbochargers, MAN Energy Solutions can significantly reduce turbocharger dimensions to meet current market requirements, the company said. The company reports that a key focus during the design phase was a reduction in manufacturing and operating costs while maintaining compliance with thermodynamic requirements.
“We anticipate a positive market reception for the TCT series, which is a combination of new and proven design features specifically optimised for IMO Tier 3 engines,” said Ralph Klaunig, vice president MAN Energy Solutions. We’ve targeted a smaller, lighter design with a superior charging-efficiency, and a high air-pressure in this new generation. As our guests have just seen, the TCT concept is so service-friendly that even a pair of managers can take a unit apart.”
The company said the TCT series’ two-stage turbocharging solution achieves efficiency levels of up to 80%. MAN Energy Solutions states that it is currently offering just the TCT40 and TCT60 types, but expects the other TCT sizes to come on stream by 2020 and 2021. MAN Energy Solutions said that the TCT40 was already sold to two customers and is currently undergoing its first field test, while the TCT60 will be delivered to its first customer mid of 2020.
The company also states that the TCT is not only aimed at low-speed engines, but is also eminently suitable for two-stage turbocharging on four-stroke engines. Alexander Schäfer said: “MAN TCT turbochargers are high-performance solutions that are built upon an unparalled foundation of proven technology. We have already signed agreements with some very prominent customers for two-stage turbocharging solutions, testament to the strength of the TCT concept.”
MAN TCT turbochargers are suitable for conventional fuel and dual-fuel engines in both marine and power applications ranging from 6 MW up to 24 MW output per turbocharger.
