中文LSAH 42.3 - Cogeneration alternator
The LSAH range of alternators has been designed to maximize efficiency of cogeneration installations.
Thanks to its specific built‐in coolant circuit, heat recovery is optimized and directly fed into the larger installation. LSAH alternators are also perfectly suited for continuous service connected to the national grid. The various design elements and construction features of LSAH machines make them highly performant and durable.
