The company raised the maximum output to 4.8 MW. The new technical specifications embodied in the Delta4000 series’ first turbine, the N149/4.0-4.5, such as an improved service concept, a mobile crane solution and a more efficient electrical system, are also integral to the new N133/4.8. Equipped with serrations, the N133/4.8 turbine's sound level is limited to just 106 dB(A) when under full power, and this can be reduced as required, depending on location, to 98 dB(A) by using numerous different operating modes. The turbine comes available with hub heights of 78, 83 and 110 metres and the start of series production of the N133/4.8 is scheduled for 2019.
