The Chicago Pneumatic CPG 25 is a towable diesel generator delivering 20 kW / 25 kVA of prime power (22 kW / 28 kVA standby) from an Isuzu 4LE2T diesel that meets Tier 4 Final emissions. It puts out 480Y/277V three-phase and 240/120V single-phase at 60 Hz through a Leroy Somer alternator with AREP excitation and Class H insulation, and its 75-gallon tank runs 48 hours at 75% load – the longest autonomy in the CPG range. At 67 dB(A) at 23 feet it’s quiet enough for populated jobsites and events.
