K
oEnrogen has designed, installed, and also commissioned three 600kVA diesel generators, and a switchboard & permanent loadbank unit at a hospital in northern England. The Enrogen generator sets were built with MTU 12V1600G20F engines (400 – 230 V/662 kVA/50 Hz/prime power/ series 1600 – 12V1600) coupled to Leroy Somer LSA49.3S4 alternators with acoustic attenuation rated at 70dBA @ 1mtr. Also provided were ComAp controls for set-to-set synchronising with n+1 configuration. The Nidec Leroy-Somer LSA 49.3 alternator has been designed to offer you the best power generation performances, says the manufacturer. With its meticulous design and optimised architecture, the LSA 49.3 is said to ‘strike the perfect balance between compactness, reliability, performance and longevity’. Whatever your application, the LSA 49.3 will meet your needs and will adapt to all situations, says the company. The Nidec Leroy-Somer LSA 49.3 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. The Nidec Leroy-Somer LSA 49.3 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.
Special features The Enrogen-built switchboard was designed to fit within the plant room with the generators. A temporary switchboard was used during the cable migration so the hospital could continue operations whilst keeping shut-downs to a minimum; this was achieved out of normal working hours. The fuel system was designed and arranged for 72-hr running with a recirculating system from the Enrogen-built underbase 10hr-day tanks back to the bulk tank for fuel polishing. An ASCO (Froment) Permanent Loadbank was supplied
so the generators can be tested individually or synchronised together. ASCO loadbanks use market-leading SIGMA Control to provide features and benefits for any load bank application. Formed in 2005, Enrogen specialises in the manufacture of diesel generators for the world market. The company offers a comprehensive range of generator services for end users, OEMs, dealers, and distributors both nationally and internationally. www.enrogen.com
