Product overview

Heavy-duty natural gas generator sets for sites without a reliable grid

One natural gas package package, 640 kW prime and 704 kW standby (800 kVA), aimed at heavy industrial and project power.

This 640 kW Natural Gas Generator Set is specified for mining and aggregate sites, district cooling and chiller plants, hospitals and institutional campuses. Typical duty for the 640 kW set is continuous prime duty at high load factor, feeding main switchboards with motor-starting and step-load duty.

Assembly and full-load testing take place on Outevo’s own lines. The company has built diesel and gas sets including this 640 kW class generator sets since 2006 at a 20,000 m² manufacturing facility served by a fully automatic line; over 2,000 sets have shipped to more than 100 countries.

The 640 kW package is protected to IP23 or higher and can be uprated for dust, humidity, rain or heat.

Product features

Engineered for site conditions, not for the showroom

Heavy-Duty Natural Gas Construction

Gas engine, alternator and control system are assembled on a rigid steel base with anti-vibration isolators, then piped and wired as a single 640 kW package.

640 kW Prime / 704 kW Standby Duty

640 kW prime / 704 kW standby at 380/220 V, 50 Hz, 1500 rpm — 800 kVA. Duty assumed for the 640 kW set is continuous prime duty at high load factor, feeding main switchboards with motor-starting and step-load duty.

Tier-1 Natural Gas Engine Platforms

The 640 kW set can be built on gas platforms from Cummins and Weichai, engine matched to alternator, with alignment and full-load testing in our own facility.

Closed Water-Cooling with Forced Fan

Cooling on the 640 kW set is closed-circuit water with a forced fan and generously sized tank, keeping temperatures steady in long runs and hot conditions.

Industrial Protection and Environmental Adaptability

Sealing and anti-corrosion treatment take the 640 kW package to IP23 or higher, with higher ratings on request, so it stays in service through dust, rain, snow and temperature swings.

Flexible Configuration and Fast Deployment

For the 640 kW unit, ATS, remote monitoring, cable winch and quick connectors shorten wiring and starting; mounting and control settings follow your project specification.

Applications

Where this 640 kW natural gas generator set is used

1. Process plants For process plants and heavy machinery the 640 kW rating covers heavy industrial and project power at continuous prime duty at high load factor. High load factor means the 640 kW rating is checked against continuous duty rather than peak only.

2. Mining Where mining and aggregate sites is the load, the 640 kW rating is normally specified at continuous prime duty at high load factor. Large motor starts and step loads drive the alternator sizing at 640 kW.

3. District cooling The 640 kW natural gas generator set set suits district cooling and chiller plants. Duty is continuous prime duty at high load factor. Parallel operation and load sharing on the 640 kW set are normally specified where redundancy is required.

4. Hospitals Hospitals and institutional campuses is a standard application for the 640 kW unit, which runs at continuous prime duty at high load factor. Main switchboard interface for the 640 kW set and protection coordination are reviewed with the site electrical design.

5. Oil The 640 kW set is commonly applied to oil and gas field facilities at continuous prime duty at high load factor. Fuel storage and day-tank arrangement for the 640 kW set are confirmed against the project fire and safety scheme.

6. Large construction packages For large construction packages the 640 kW rating covers heavy industrial and project power at continuous prime duty at high load factor. Ambient and altitude derating for the 640 kW set are applied where the site sits above sea-level design conditions.

FAQ

Frequently asked questions about this 640 kW natural gas generator set

What power rating does this generator set provide?

This unit is rated 640 kW prime / 704 kW standby (800 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 natural gas engines are available for this set?

This 640 kW set is available on Cummins and Weichai platforms. The engine is matched to the alternator at the 640 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.

Natural Gas, silent or containerized — how do I choose?

Enclosure choice follows site conditions rather than rating. This page covers the natural gas package build; at 640 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 and load sharing can be specified.

Can the voltage and frequency be customised?

Yes. 380/220 V and 50 Hz are the published standard for the 640 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 640 kW unit can be ordered for a standalone site; where load growth or redundancy is expected, parallel operation and load sharing can be specified. Other ratings in the 10–3,750 kVA range are quoted per project.

How is the quality of each unit assured?

Every 640 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 manufacturing facility.
