FOUR NEW DIESEL GENSETS (4 X 3250 KVA) INSTALLED IN A DATA CENTRE IN SOUTH KOREA

Four KD3250UE generators and customised a master control panel were recently provided to synchronise a power system for a data centre customer in South Korea.

Kohler Engineers supported the company’s partner in Korea, Coastal Power, on the Site Acceptance Test and Integrated System Test; this was carried out in the presence of the customer’s nominated Commissioning Agent. Kohler engineers also provided hands-on training to Coastal Power and its personnel at their workshop.

Each KOHLER diesel-powered generator set and its components are prototype-tested, factory-built, and production-tested before despatch.

The 60 Hz generator set offers a UL 2200 listing. The 60 Hz generator set meets NFPA 110, Level 1, when equipped with the necessary accessories and installed per NFPA standards. A three-year limited warranty covers all systems and components is also provided. Details on the genset are as follows:

-Standby Range (kW/kVA) 3250/4062;

-Prime Range (kW/kVA) 2950/3688

- Continuous Range (kW/VA) 2450/3062

-Frequency 60 Hz & Speed 1800 RPM

-Alternator Type: Brushless, Permanent-Magnet Pilot Exciter

Controllers are available for all applications involved with the KD3250UE gensets. In each genset, a low coolant level shutdown feature prevents overheating (standard on radiator models only).

An electronic, isochronous governor delivers precise frequency regulation, while there are multiple circuit breaker configurations to suit a wide variety of applications

A pilot-excited, permanent-magnet (PM) alternator provides superior short-circuit capability, and each set offers NEMA MG1, IEEE, and ANSI standards compliance for temperature rise and motor starting.

Superior voltage waveform is achieved from two-thirds pitch windings and skewed stator; the brushless alternator with brushless pilot exciter provides excellent load response.

Each set is capable of a sustained short-circuit current of up to 300% of the rated current for up to 10 seconds and enables downstream circuit breakers to trip without collapsing the alternator field. The genset itself features selfventilated and drip-proof construction.

KOHLER’s KD range of standby generating sets runs from 800 to 4500kVA at 50Hz. The KD range offers the highest power level on the market in its category with the latest generation Kohler engine technology. The flexibility and modularity of the KD SERIES generating sets make this the ideal range for tailored power solutions, perfectly suited to the most demanding applications and environments.

Common rail injection with electronic control enables optimisation of both fuel consumption and emissions.

Emissions optimised versions conform to EPA Tier 2 requirements at 50Hz and are EPA Tier 2 certified at 60Hz. EPA Tier 4 certified from 1250kVA – 3250kVA. With no DPF (Diesel Particulate Filter), no DOC (Diesel Oxidation Catalyst) and only SCR (Selective Catalytic Reduction).

The KD Series of gensets also features compact design. Ideal for space-saving, the KD SERIES has a compact design and separate cooling for smoother installation.

Available with DCP power for data centres, the range includes a large number of options and accessories; control/command enclosures and containers, fuel tanks, silencers and circuit breakers.

Available with a wide variety of containerised gensets options, KOHLER’s gensets can be adapted to meet a client’s needs: Their standard dimensions mean they’re easy to transport, and the integrated fuel tank means they are ready to run. The gensets feature:

- ISO Containers – for emergency applications with no harsh environmental constraints

-CPU Containers – for the most demanding environments, these robust modular containers are designed to meet the most stringent of production applications

-Walk-in Enclosures – designed for data centres, these enclosures combine performance, reliability, strength, safety and modularity.
