| Technical details / open items | 25 units immediately available in the offered 50 Hz configuration.; Jenbacher J420E enclosed natural gas generator packages, nominal 1.5 MW each, 50 Hz, 400/231 V.; The units are offered in their existing 50 Hz configuration. Any frequency conversion is entirely the buyer's responsibility, arranged and paid for by the buyer. J&J does not perform or include conversion.; A buyer considering conversion must obtain an approved engineering scope for the exact engine, alternator, controls, auxiliaries and resulting output rating.; Generator breaker and connection point included per supplied specification. SCR is a project-specific optional addition.; Contact Tommy for pricing, matching nameplates, current photos, inspection and release terms. | 25 brand-new units; separate from the 100-unit used QSK60 G5 offer.; Continuous output in the supplied datasheet: 1,300 kW / 1,625 kVA at 60 Hz; 1,120 kW / 1,400 kVA at 50 Hz (approximately 1.1 MW).; The datasheet identifies GQSK60-G5 for 50 Hz and GQSK60-G8 for 60 Hz. Specify the required frequency before ordering; these ratings describe the corresponding configurations.; Output voltage ranges: 380-440 V at 50 Hz and 416-480 V at 60 Hz. Engine speed: 1,500 RPM at 50 Hz and 1,800 RPM at 60 Hz.; V16 engine with Cummins MCM700 governor; PE734E brushless alternator, permanent-magnet excitation and Class H insulation.; Datasheet package includes a Schneider NW25 four-pole breaker rated 2,500 A and a containerized cooling arrangement. Final accessories and supplied configuration per quotation.; The lower container measures 6.06 m x 2.44 m x 2.59 m. Total wet package weight is 26,840 kg including the upper cooling container; confirm assembled and shipping dimensions for logistics.; Contact Tommy Marco for pricing, current photos, the complete technical package and delivery timing. |
