Cogeneration generator set QSK60G series

gasthree-phasestationary

Overview
The QSK60G series is a lean‑burn gas generator family for primary and peaking power applications. It combines Miller‑cycle, fully electronic engine management with gas‑specific combustion technology to deliver high fuel efficiency, low NOx emissions and reduced maintenance for lower total cost of ownership. The series has a global installed base exceeding 2 GWE and is available in 50 Hz and 60 Hz configurations.

Features and benefits

• LOW NOx EMISSIONS: Lean‑burn combustion supporting exhaust NOx levels down to 250 mg/Nm3 (0.5 g/hp‑hr).
• HIGH EFFICIENCY: Miller‑cycle lean‑burn engine with full electronic management delivering ISO electrical efficiencies up to 43.8% (model dependent).
• CONTROL INTEGRATION: PowerCommand 3.3 generator set control (standard) providing full system integration, paralleling capability, precise frequency and voltage regulation, alarms, AmpSentry™ protection and automatic shutdown on fault; local control panel installed; remote controls optional.
• COOLING FLEXIBILITY: Provision for remote radiator or heat exchanger connection.
• ALTERNATOR OPTIONS: Multiple alternator sizes with selectable voltage and temperature rise, 2/3 pitch windings, low waveform distortion on non‑linear loads and short‑circuit capability; bearing and stator RTDs, anti‑condensation heater, insulation class F or H options.
• PMG EXCITATION: Permanent magnet generator excitation for improved short‑circuit performance during start and fault conditions.
• GLOBAL SUPPORT: Worldwide service network with factory‑level product knowledge and local service capacity to minimize downtime and lifecycle cost.
