Product overview

Heavy-duty open frame diesel generator sets for sites without a reliable grid

Rated 450 kW prime and 495 kW standby at 562 kVA, supplied as a open frame set unit for mid-size industrial and site power.

Where it is installed — data and telecom rooms, quarries and crushing plants, agricultural processing — the 450 kW set works at continuous prime duty with regular load swings. Distribution for the 450 kW set is usually through panel boards with mixed motor and lighting loads.

Each 450 kW set is assembled and load-tested in our own works. Outevo has produced diesel and gas sets including this 450 kW rating generating sets since 2006 from a 20,000 m² production base in Shandong with a fully automatic line, and has delivered more than 2,000 sets to over 100 countries.

IP23 or higher protection is standard on the 450 kW set, with higher grades available for dust, humidity, rain or heat.

Product features

Engineered for site conditions, not for the showroom

Heavy-Duty Open Frame Construction

A rigid fabricated steel base carries the engine, alternator and control system on anti-vibration mounts. Nothing is enclosed, so every service point stays open to the site.

450 kW Prime / 495 kW Standby Duty

The 450 kW prime / 495 kW standby rating is declared at 380/220 V, 50 Hz, 1500 rpm (562 kVA), intended for continuous prime duty with regular load swings across panel boards with mixed motor and lighting loads.

Tier-1 Diesel Engine Platforms

Engine options for the 450 kW diesel set are Cummins, Perkins, Weichai and Yuchai; whichever is specified, the engine is matched to the alternator and load-tested in our own works.

Closed Water-Cooling with Forced Fan

The 450 kW package uses closed water-cooling with forced ventilation and a large-capacity tank, holding temperatures steady during extended continuous duty in hot climates.

Industrial Protection and Environmental Adaptability

Enclosure sealing and anti-corrosion finishing are rated IP23 or higher on the 450 kW set, upgradable for harsher sites, treating dust, rain, snow and temperature extremes as normal conditions.

Flexible Configuration and Fast Deployment

Options on the 450 kW set include an automatic transfer switch, remote monitoring, cable winch and quick connectors; base-frame arrangement and control, protection and voltage settings are set to the project specification.

Applications

Where this 450 kW open frame diesel generator set is used

1. Production lines Production lines and compressors is a standard application for the 450 kW unit, which runs at continuous prime duty with regular load swings. Mixed motor and lighting load means the alternator is matched with step-load margin at 450 kW.

2. Hotels The 450 kW set is commonly applied to hotels and commercial buildings at continuous prime duty with regular load swings. Shift patterns for the 450 kW set usually mean 12–16 hours a day, so fuel autonomy is calculated on that basis.

3. Data For data and telecom rooms the 450 kW rating covers mid-size industrial and site power at continuous prime duty with regular load swings. Compressor and motor starts drive the transient requirement, which is checked against the 450 kW rating.

4. Quarries Where quarries and crushing plants is the load, the 450 kW rating is normally specified at continuous prime duty with regular load swings. Parallel operation on the 450 kW set is often considered where duty is split between two units.

5. Agricultural processing The 450 kW open frame diesel generator set set suits agricultural processing. Duty is continuous prime duty with regular load swings. Sound limits at the boundary usually point to a canopy build at the 450 kW rating.

6. Site offices Site offices and welfare blocks is a standard application for the 450 kW unit, which runs at continuous prime duty with regular load swings. Cable runs for the 450 kW set are longer, so voltage drop is checked before the final rating is fixed.

FAQ

Frequently asked questions about this 450 kW open frame diesel generator set

What power rating does this generator set provide?

This unit is rated 450 kW prime / 495 kW standby (562 kVA) at 380/220 V, 50 Hz, 1500 rpm. Rated current is stated on the approved data sheet for the selected build, because it follows the voltage and power factor confirmed for the project.

Which diesel engines are available for this set?

This 450 kW set is available on Cummins, Perkins, Weichai and Yuchai platforms. The engine is matched to the alternator at the 450 kW rating and the complete set is aligned and full-load tested in our own works, so the platform for your order is confirmed at specification stage rather than assumed.

Open Frame, silent or containerized — how do I choose?

Enclosure choice follows site conditions rather than rating. This page covers the open frame set build; at 450 kW the same engine and alternator package can also be supplied in the other builds across Outevo’s 10–3,750 kVA range, with parallel operation is available where duty is split across two units.

Can the voltage and frequency be customised?

Yes. 380/220 V and 50 Hz are the published standard for the 450 kW rating, but voltage and frequency are set to your project specification under OEM/ODM terms, including 60 Hz and medium-voltage requirements where the project calls for them.

What is the minimum order quantity?

One set. A single 450 kW unit can be ordered for a standalone site; where load growth or redundancy is expected, parallel operation is available where duty is split across two units. Other ratings in the 10–3,750 kVA range are quoted per project.

How is the quality of each unit assured?

Every 450 kW set is assembled and load-tested on our own production lines before shipment, and travels with a data sheet and test record. Shanghai Outevo Machinery Co., Ltd. has manufactured diesel and gas generator sets since 2006 from a 20,000 m² production base in Shandong.
