Gaseous Fueled Engine Generator Sets: Liquid Cooled, Four-Cycle

Alturdyne Basic Model ARNC-XXX (65 - 820 kW)-060-H* 2001 Ratings

Package Configuration

Basic package consists of diesel engine coupled to generator and assembled on structural steel skid with unit mounted radiator and pusher fan, control panel, and accessories. Electronic governor is standard along with flex fuel lines and fuel/water separator and base isolation pads

 

Alturdyne designed/manufactured engine and generator control panel is unit mounted and  contains ammeter, voltmeter, AM/VM select switch, frequency meter, voltage adjust rheostat, oil pressure gauge, water temperature gauge, three-position mode switch, panel lights, cycle crank with safeties for overspeed, low oil pressure, high water temperature and overcrank. Customer connections and remote alarms are located on isolated terminal strip.

 

Generator leads terminate in an oversize box or at back of circuit breaker located in adjacent NEMA 1 box.

Engine

All engines are in-line, multi-cylinder  diesels with direct injection and have replaceable wet liners.  Units are either naturally aspirated (NA), turbocharged (T), turbocharged with air aftercooling (TA) or turbocharged with water aftercooling (TW).  Rotary (R) or in-line (I) injection pumps are used.  Emissions and acoustics are low.  Accessories include fuel pump, primary and secondary fuel filters, lube oil pump and cooler, lube oil filter, water pump, exhaust  manifold, jacket water heater, stainless flex exhaust coupling, insulation blankets, DC starter and battery charging alternator.

Generator

Generators are four pole, brushless broad  range machines with a single permanently lubricated, double shielded radial ball bearing and flywheel disc drive coupling.  The revolving field design contains a direct drive exciter and stator windings are 2/3 pitch with vacuum epoxy impregnation. Design is to NEMA and International Standards and insulation is either Class F or H. Generator feature a TIF of <50, radio interference, a wave form deviation of <5%, harmonic content of 3% max and a voltage regulation of 1% with standard static regulator.
