Nidec Leroy-Somer launches LSAH 42.3 generator

38631 LSAH 423Nidec Leroy-Somer has announced the launch of the LSAH 42.3 to extend its range of industrial alternators optimised for cogeneration applications

The LSAH 42.3 is being released to complement the LSAH 44.3 released last year. It uses the same heat recovery system, and features leading electrical and thermal efficiency values.

The LSAH 42.3 has been designed to be packaged into small natural gas generator sets built for combined production of heat and electricity. The main application of these gensets are residential and public buildings central heating.

The LSAH 42.3 delivers a rated power between 10 and 33 kVA at 50 Hz in continuous service (from 12.5 to 41 kVA at 60 Hz). The alternator is fitted as standard with an AREP excitation system and a D350 regulator. Paralleling with the public network for the resale of electricity production surplus is also possible with a D550 AVR.

Thanks to its cooling and heat recovery system, the LSAH 42.3 offers premium performance, especially in situations of intensive use:

- The electrical efficiency reaches 94% and generally remains above 90%. These unprecedented values help increase the global energetic performance of the cogeneration system.

- Thanks to the optimised cooling system, the lifespan of the machine is increased and allows continuous operation of the system without any risk of failure due to hotspots.

- Water cooling also allows the use of the LSAH 42.3 in non-ventilated – and silent – generator sets, making their integration in buildings much easier with and without noise pollution for the neighbourhood.

The general characteristics of alternators in the new LSAH range also make them suitable for other applications where high efficiency, water cooling, low vibrations, low noise or continuous operation at high temperature are needed. These requirements are typically found in traction, hoisting or marine applications.
