Product overview

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

One natural gas package package, 500 kW prime and 550 kW standby (625 kVA), aimed at mid-size industrial and site power.

This 500 kW Natural Gas Generator Set is specified for hotels and commercial buildings, data and telecom rooms, quarries and crushing plants. Typical duty for the 500 kW set is continuous prime duty with regular load swings, feeding panel boards with mixed motor and lighting loads.

Assembly and full-load testing take place on Outevo’s own lines. The company has built diesel and gas sets including this 500 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 500 kW package is protected to IP23 or higher and can be uprated for dust, humidity, rain or heat.

• ✓500 kW prime / 550 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 500 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.

500 kW Prime / 550 kW Standby Duty

Design duty at 500 kW prime and 550 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 500 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.

FAQ

Frequently asked questions about this 500 kW natural gas generator set

What power rating does this generator set provide?

This model is rated 500 kW (625 kVA) prime and 550 kW standby with the KTA19-G8A 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 500 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 500 kW rating, and voltage and frequency follow the building specification under OEM/ODM terms.

What is the minimum order quantity?

One 500 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 500 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.
