Echo DGK45F Diesel Generator
Echo DGK45F 45 kVA industrial diesel generator — 36 kW (45 kVA) 3-phase / 27 kW 1-phase continuous, 63 dB(A) at 23 ft, Isuzu 4LE2X, 4 cylinder, 28 hr runtime at full load.
The ECHO DGK45F is a Tier 4 Final mobile diesel generator rated 36 kW (45 kVA) continuous three-phase and 27 kW (27 kVA) continuous single-phase, built around an Isuzu 4LE2X 4-cylinder engine in an enclosure ECHO rates at 63 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, intercooled. 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 4LE2X diesel. Direct injection, turbocharged, intercooled, 133 cu in (2.179 L), 59 hp @ 1800 rpm. US EPA Tier 4 Final.
- Standby rating. 40 kW (50 kVA) three-phase, above the continuous rating, for backup duty rather than prime power.
- Output. 240 / 480 V three-phase and 120 / 139 / 240 V (277 V) single-phase. 112 A x2 at 120 V and 112 A at 240 V single-phase; 108 A at 240 V and 54 A at 480 V three-phase. Frequency regulation 60 Hz ±0.25%.
- 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.
- Fuel. 79 gal (300 L) internal with 110% fluid containment. Burn is 2.8 gal/hr at full load, 2.1 at 3/4, 1.5 at 1/2 and 0.9 at 1/4 — about 28 hours at full load on the internal tank, less as you load it harder than a rental set usually runs.
- Sound. 63 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. 83" x 37" x 61", 2,634 lb dry. Trailered: 154.25" x 70.60" x 83.58", 3,784 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.
