Built to heat
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.
Nidec Leroy-Somer LSAH 44.3 alternator meets all key international standards and regulations, including IEC 60034, NEMA MG 1.32-33, ISO 8528-3, CSA C22.2 n°100-14 and UL 1446 (UL 1004 on request).
Also compliant with IEC 61000-6-2, IEC 61000-6-3, IEC 61000-6-4, VDE 0875G, VDE 0875N and EN 55011, group 1 class A for European zone.
Nidec Leroy-Somer LSAH 44.3 alternator can be integrated in EC marked generator set, and bears EC, EAC and CMIM markings.
It is designed, manufactured and marketed in an ISO 9001 and ISO 14001 quality assurance environment.
