Product overview

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

400 kW prime / 440 kW standby — 500 kVA — built as a natural gas package package for mid-size industrial and site power.

Plants in industrial zones frequently run on generated power for the whole working day. This 400 kW silent set (500 kVA prime, 440 kW standby) is rated for that continuous duty rather than short standby use. Continuous running puts the emphasis on cooling and fuel system stability. The QSZ13-G10 engine is matched to the 400 kW rating with a closed water-cooling circuit and a large-capacity water tank, and each unit is load-tested on our production lines.

Every unit is assembled and load-tested on our own production line for the 400 kW class. A factory set usually sits inside or beside the production building, so the enclosure is lined to keep radiated noise down. The silent build measures 4,800 × 1,380 × 2,240 mm and is protected to IP23 or higher. Shanghai Outevo Machinery Co., Ltd. has manufactured diesel and gas generator sets since 2006 from a 20,000 m² manufacturing facility, and more than 2,000 sets have been delivered to over 100 countries.

Protection on the 400 kW set is IP23 or higher, upgradable for dusty, humid, rainy or high-temperature sites.

• ✓Tier-1 diesel engine platforms — Cummins, Perkins, Weichai and Yuchai
• ✓Closed water-cooling with forced fan and large-capacity water tank
• ✓IP23 or higher, upgradable for dust, humidity, rain and heat

Product features

Engineered for site conditions, not for the showroom

Heavy-Duty Natural Gas Construction

The 400 kW package is delivered assembled on its base frame, so installation inside or beside the production building is limited to positioning, fuel connection and cabling.

400 kW Prime / 440 kW Standby Duty

Design duty at 400 kW prime and 440 kW standby is continuous running through the working day, which is why the alternator and cooling system are sized for sustained load rather than short standby duty.

Tier-1 Natural Gas Engine Platforms

The engine is drawn from the Cummins, Perkins, Weichai and Yuchai platforms and matched to the alternator before full-load testing on our own production line.

Closed Water-Cooling with Forced Fan

Closed-circuit water cooling with forced fan and a large water tank is specified because a plant set runs for whole shifts and cannot rely on short cooling recovery periods.

Industrial Protection and Environmental Adaptability

Sealed dustproof, waterproof and anti-corrosion treatment to IP23 or higher, uprated for foundry dust, humid areas or high ambient workshops.

Flexible Configuration and Fast Deployment

ATS, remote monitoring, cable winch and quick connectors can be specified so the set can be redeployed between bays or buildings as the plant layout changes.

Applications

Where this 400 kW natural gas generator set is used

1. Production lines and machine tools Carries the whole working-day load of the plant where the grid supply is either absent or too weak to run the line.

2. Compressors and process pumps Takes the starting current of large motors and keeps process pumps running without an operator restarting them after each trip.

3. Furnaces, dryers and ovens Holds process temperature through a shift, which is what prevents scrap and rework when the supply is unstable.

4. Cold storage and process cooling Keeps refrigeration and cooling loops live, protecting product that would otherwise be lost in a long outage.

5. Workshop and maintenance bays Runs welding, lifting and compressed-air equipment in the maintenance area independent of the main supply.

6. Shift-pattern continuous demand Suits plants that work two or three shifts, where the set is the primary source and fuel and service planning follows production hours.

FAQ

Frequently asked questions about this 400 kW natural gas generator set

What power rating does this generator set provide?

This model is rated 400 kW (500 kVA) prime and 440 kW standby, built on the QSZ13-G10 engine with a silent canopy of 4,800 × 1,380 × 2,240 mm. It is intended for continuous prime duty, not standby only.

Which natural gas engines are available for this set?

Outevo assembles and load-tests every set before shipment; the same rating is available in open frame, containerized and mobile builds under OEM/ODM terms.

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

Enclosure choice follows where the set is installed, not the rating. At 400 kW the silent build suits a plant room or a yard close to occupied workshops; containerized and mobile builds use the same engine and alternator.

Can the voltage and frequency be customised?

Yes. 380/220 V and 50 Hz are the published standard for the 400 kW rating, and voltage and frequency are set to the plant specification under OEM/ODM terms.

What is the minimum order quantity?

One 400 kW unit is enough to start. Where the connected load grows with additional lines, parallel operation and load sharing are configured so capacity can be added without replacing the set.

How is the quality of each unit assured?

Every 400 kW set is assembled and load-tested on our own production lines before shipment, with a data sheet and test record. Shanghai Outevo Machinery Co., Ltd. has manufactured generator sets since 2006 and delivered more than 2,000 units to over 100 countries.
