Echo DGK125F Diesel Generator
Echo DGK125F 125 kVA industrial diesel generator — 100 kW (125 kVA) 3-phase / 75 kW 1-phase continuous, 65 dB(A) at 23 ft, Isuzu 4HK1X, 24 hr runtime at full load.
The ECHO DGK125F is a Tier 4 Final mobile diesel generator rated 100 kW (125 kVA) continuous three-phase and 75 kW continuous single-phase, built around an Isuzu 4HK1X engine in an enclosure ECHO rates at 65 dB(A) at no load, measured at 23 ft. It is designed for rental fleets and contractors — equipment that gets used hard, moved often, and maintained on a schedule.
Altitude
ECHO does not publish a derate figure for this machine — not on the sell sheet and not on the spec page. That is worth saying plainly rather than filling the gap with someone else's number. What the sheet does give is the engine and how it breathes, and here that works in your favour: this one is direct injection, turbocharged, with DOC and SCR. A turbocharged diesel holds its rating at elevation far better than a naturally aspirated one, because the turbo restores intake density that thin air takes away. On the Front Range that difference is worth real money — it is often the reason a turbocharged set one size down does the job that a naturally aspirated set one size up cannot.
We are at 6,035 ft in Colorado Springs and we sell into sites well above that. Tell us the elevation the machine will actually work at and we will get the derate in writing from ECHO before you order, rather than after you find out. A set that is quietly short of its nameplate at 8,000 ft is the most common and most expensive mistake in this business, and it is entirely avoidable.
Options. Trailer, block heater, battery charger, cam locks, fire extinguisher and shore power are factory options ordered with the unit — ask and we will quote the machine as you actually want it configured.

Features and specifications
- Isuzu 4HK1X diesel. Direct injection, turbocharged, with DOC and SCR, 316 cu in (5.193 L), 152.3 hp (113.6 kW) @ 1800 rpm. US EPA Tier 4 Final.
- Standby rating. 110 kW three-phase, above the continuous rating, for backup duty rather than prime power.
- Output. 208 / 240 / 480 V three-phase and 120 / 240 V single-phase. 347 A at 208 V, 301 A at 240 V and 150 A at 480 V three-phase; 313 A x2 at 120 V and 313 A at 240 V single-phase. Frequency regulation 60 Hz ±0.15%.
- Simul-Phase®. Single-phase and three-phase output at the same time, from the same machine, without a transformer. One set covers a mixed site instead of two.
- Priority trip breakers. Separate breakers for single- and three-phase loads, so an overload on one side does not take down the other.
- S.E.T. Smart Emissions Technology™. Protects the aftertreatment during light or underloaded running — which is most of what a rental set actually does.
- Fuel. 171.7 gal (650 L) internal with 110% fluid containment. Burn is 7.1 gal/hr at full load, 5.5 at 3/4, 3.9 at 1/2 and 2.1 at 1/4 — about 24 hours at full load on the internal tank, less as you load it harder than a rental set usually runs.
- DEF. 7.4 gal x2 (28 L x2).
- Sound. 65 dB(A) at no load and 66 dB(A) at full load at 23 ft, using a tuned muffler, longer exhaust and air dams that double the cooling path rather than insulation alone.
- Size and weight. 120" x 48.8" x 59.1", 6,592 lb dry. Trailered: 189.89" x 79.75" x 91.23", 8,117 lb.
- Alternator. Revolving field brushless AC. 12 V DC electric starting.
Ultra-quiet design
Echo industrial generators are built for sound-sensitive jobsites: air dams and insulated panels double the cooling air path, heavy-gauge door panels and sound-absorbing foam damp the enclosure, and a tuned muffler with an extended exhaust pipe cuts both high and low frequency noise -- without power-robbing auxiliary fans.
Simul-Phase®
Simul-Phase® delivers single- and three-phase power at the same time from a split buss, with 120/240V single-phase available at every voltage setting -- no transformer required. Priority trip breakers separate single- and three-phase loads so preferred circuits stay up during an overload.
S.E.T. Smart Emissions Technology™
S.E.T. Smart Emissions Technology™ provides added aftertreatment protection during light or underloaded operation -- the condition that most often fouls Tier 4 emissions systems on standby and rental duty.
