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.

Offices, retail and mixed-use buildings need a supply that carries services without becoming a nuisance to tenants or neighbours. This 400 kW silent set (500 kVA prime, 440 kW standby) is specified for that role. The critical loads are lifts, HVAC, pumps and building management, all started at once when the mains drops. The QSZ13-G10 engine is matched to the 400 kW rating with headroom for those starting surges.

Every unit is assembled and load-tested on our own production line for the 400 kW class. The unit is enclosed in a sound-absorbing canopy measuring 4,800 × 1,380 × 2,240 mm and protected to IP23 or higher, so it can be installed in a service yard or basement plant room. Each set is load-tested before shipment. 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.

• ✓400 kW prime / 440 kW standby at 380/220 V, 50 Hz, 1500 rpm
• ✓Full service access — gas train, ignition and control all reachable on site
• ✓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 supplied as one assembled unit, so the installation in a service yard or plant room is a positioning, fuel and cabling task rather than a build.

400 kW Prime / 440 kW Standby Duty

Design duty at 400 kW prime and 440 kW standby covers lifts, HVAC and pumps starting together, which is the sizing case rather than the steady running load.

Tier-1 Natural Gas Engine Platforms

The engine is drawn from the Cummins, Perkins, Weichai and Yuchai platforms, aligned to the alternator and fully load-tested before shipment.

Closed Water-Cooling with Forced Fan

Closed-circuit water cooling with forced fan and a large water tank keeps the set stable while it carries building services through an outage.

Industrial Protection and Environmental Adaptability

Sealed dustproof, waterproof and anti-corrosion treatment to IP23 or higher, with alarm contacts available for building management systems.

Flexible Configuration and Fast Deployment

ATS, remote monitoring and quick connectors can be specified so the transition is automatic and the facilities team is alerted remotely.

Applications

Where this 400 kW natural gas generator set is used

1. Lifts and building transport Keeps lift service available so occupants can leave and enter the building normally during an outage.

2. HVAC and ventilation Keeps air handling and ventilation running in occupied floors and car parks.

3. Water booster and drainage pumps Carries domestic water boosters and sump pumps so services continue without manual intervention.

4. Lobby, car park and facade lighting Supplies the lighting required for circulation and security in commercial premises.

5. Fire and life-safety systems Backs up fire pumps, smoke control and alarm panels required for safe occupancy.

6. Tenant IT and comms rooms Supplies tenant comms cabinets and building IT rooms where loss of service is immediately visible.

Open frame, silent or containerized?

The same engineering and testing standard applies to this 400 kW rating in all three builds — the difference is enclosure, access and transport.

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 with the QSZ13-G10 engine in a silent canopy of 4,800 × 1,380 × 2,240 mm. Voltage, frequency and protection follow the project specification.

Which natural gas engines are available for this set?

Commercial buildings normally take this rating as a silent set for service-yard locations; containerized and mobile builds are available for the same rating under OEM/ODM terms.

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

Enclosure choice follows the installation point, not the rating. At 400 kW the silent build suits a service yard or basement plant room; open frame 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 follow the building specification under OEM/ODM terms.

What is the minimum order quantity?

One 400 kW unit covers a single building. Where tenants or an extension are added later, parallel operation and load sharing are configured so capacity can grow.

How is the quality of each unit assured?

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