Overview

The Kirloskar KG4-125WS1 is a 125 kVA (100 kW) 3-phase prime-rated diesel generator built to CPCB IV+ emission standards, engineered for high-duty continuous operation and large facility backup.

Driven by a four-cylinder 4K1080ETA 4G1 engine (4.32 L cubic displacement, turbocharged and after-cooled) rated at 114.7 kW (156 HP) at 1500 rpm with common rail direct injection (CRDi). Features DOC + SCR exhaust treatment with a 25 L DEF capacity.

Supplied in an acoustic canopy rated under 75 dBA at 1 metre, with a 230 litre fuel tank, set-mounted radiator (17.7 L coolant), 12V DC starting, and the KG640C microprocessor controller with integrated AMF.

Backed by professional engineering support, local warranty, and rapid spares availability across Nagaland.

Applications

Commercial complexes, malls, and corporate offices
Medium and large manufacturing plants
Hospitals, diagnostic centres, and critical care units
Universities, colleges, and institutional campuses
Hotels, resorts, and convention centres
Infrastructure, highway, and large construction projects
Cold storage, agro-processing, and warehouse logistics
Continuous industrial power and heavy standby backup

Key features

CPCB IV+ compliant with DOC & SCR: Meets Central Pollution Control Board IV+ emission norms using a Diesel Oxidation Catalyst (DOC) and Selective Catalytic Reduction (SCR) with DEF dosing to cut NOx, HC, and particulate matter.
Common rail direct injection (CRDi): High-pressure CRDi provides precise multi-injection fuel metering, improved fuel atomisation, smoother running, lower noise and cleaner emissions with A-class filtration.
O2E fuel & DEF efficiency: Optimal Operating Efficiency (O2E) technology optimises fuel and DEF consumption across typical 50% to 70% operational loading bands rather than full load alone, significantly reducing lifetime operating costs.
KG640C microprocessor controller: Graphical LCD controller displaying phase voltages and currents, frequency, kVA, kW, kWh, kVAr, power factor, lube oil pressure, engine temperature, RPM, run hours, number of starts, and fuel level, with integrated AMF capability and optional Modbus communication.
KRM remote monitoring: Kirloskar remote monitoring system reports real-time genset status and location to mobile or desktop, provides diagnostic telemetry, and sends automated alert notifications on critical events.
On-board diagnostics: Continuous monitoring of battery charging, over/under speed, over current, over/under voltage, phase sequence, low lube oil pressure, high engine temperature, and low fuel level to detect issues before breakdown.
Rugged Class H alternator with digital AVR: Compact, high-efficiency Class H alternator equipped with an advanced digital AVR for tight voltage regulation (under 20% max voltage dip at full load) and rapid voltage build-up in under 2 seconds.
500-hour lube oil interval: Extended 500-hour oil change interval reduces scheduled servicing downtime and operating consumable expenses over the life of the set.
Compact acoustic canopy under 75 dBA: Integral acoustic enclosure engineered to maintain noise levels below 75 dBA at 1 metre, featuring an inbuilt silencer, high-quality base frame, and a space-saving footprint.
