Overview

The Kirloskar KG4-25WS1 is a 25 kVA (20 kW) prime-rated diesel generating set built to CPCB IV+ emission standards, delivering clean, reliable power for commercial, institutional, and light industrial facilities.

It is powered by a three-cylinder 3R550ETA 4G1 engine of 1.65 litres displacement, turbocharged and after-cooled, running at 1500 rpm with common rail direct injection (CRDi). Exhaust emissions are treated via DOC and EGR without requiring DEF fluid.

The complete set is housed in a compact acoustic canopy rated below 75 dBA at 1 metre, with a 50 litre fuel tank, 12V DC electric start, and a KG640C microprocessor controller with integrated AMF capability and comprehensive diagnostics.

We size the set against a proper load study before quoting, handle installation and commissioning, and support it locally across Dimapur and Nagaland with servicing and genuine spares.

Applications

Commercial complexes and retail outlets
Small and medium manufacturing units
Hospitals, clinics, and diagnostic centres
Schools, colleges, and educational institutions
Hotels, restaurants, and hospitality venues
Construction sites and infrastructure projects
Fuel stations and logistics hubs
Critical commercial and office backup power

Key features

CPCB IV+ compliant with DOC & EGR: Meets Central Pollution Control Board IV+ emission norms using a Diesel Oxidation Catalyst (DOC) and Exhaust Gas Recirculation (EGR) system to cut particulate matter and NOx emissions without requiring DEF dosing.
Common rail direct injection (CRDi): High-pressure CRDi fuel system delivers precise multi-stage injection metering, improved fuel atomisation, smoother running, lower combustion noise and cleaner emissions with A-class filtration.
O2E fuel efficiency: Optimal Operating Efficiency (O2E) technology optimises fuel consumption across typical 50% to 70% operational loading bands rather than full load alone, significantly lowering running 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 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.
