Product overview

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

Rated 20 kW prime and 22 kW standby at 25 kVA, supplied as a open frame set unit for small commercial and light industrial.

Where it is installed — guesthouses and small clinics, water pumps and irrigation, small cold rooms — the 20 kW set works at intermittent prime duty with frequent start-stop cycles. Distribution for the 20 kW set is usually through light single-unit distribution boards.

Each 20 kW set is assembled and load-tested in our own works. Outevo has produced diesel and gas sets including this 20 kW rating generating sets since 2006 from a 20,000 m² manufacturing facility 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 20 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.

20 kW Prime / 22 kW Standby Duty

The 20 kW prime / 22 kW standby rating is declared at 380/220 V, 50 Hz, 1500 rpm (25 kVA), intended for intermittent prime duty with frequent start-stop cycles across light single-unit distribution boards.

Tier-1 Diesel Engine Platforms

Engine options for the 20 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 20 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 20 kW set, upgradable for harsher sites, treating dust, rain, snow and temperature extremes as normal conditions.

Flexible Configuration and Fast Deployment

Options on the 20 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.

Engine & options

Specify the engine platform, control scheme and build

Engine platform Cummins · Perkins · Weichai · Yuchai For the 20 kW set the engine is drawn from these Tier-1 platforms and matched to the alternator, with the final platform fixed at order stage.

Control & protection ATS & remote monitoring An automatic transfer switch and remote monitoring module can be specified on the 20 kW set. The control and protection scheme on the 20 kW set is configured to the project specification.

Applications

Where this 20 kW open frame diesel generator set is used

1. Retail units Retail units and small offices is a standard application for the 20 kW unit, which runs at intermittent prime duty with frequent start-stop cycles. The load is usually single-phase and three-phase mixed, so the set is configured with a distribution board matched to the 20 kW rating.

2. Workshops The 20 kW set is commonly applied to workshops and repair bays at intermittent prime duty with frequent start-stop cycles. Motor starting is light, so a modest step-load margin is enough at 20 kW.

3. Guesthouses For guesthouses and small clinics the 20 kW rating covers small commercial and light industrial at intermittent prime duty with frequent start-stop cycles. Duty on the 20 kW set is intermittent, so fuel autonomy is sized around shift patterns rather than continuous run.

4. Water pumps Where water pumps and irrigation is the load, the 20 kW rating is normally specified at intermittent prime duty with frequent start-stop cycles. Ambient around the 20 kW set is often unshaded, so the radiator and enclosure are specified for high daytime temperature.

5. Small cold rooms The 20 kW open frame diesel generator set set suits small cold rooms. Duty on the 20 kW set is intermittent prime duty with frequent start-stop cycles. Noise is a factor on residential sites, so canopy options are considered at the 20 kW rating.

6. Construction hoists Construction hoists and small tools is a standard application for the 20 kW unit, which runs at intermittent prime duty with frequent start-stop cycles. Access to the 20 kW skid is usually tight, so the skid footprint and lifting points matter as much as output.

FAQ

Frequently asked questions about this 20 kW open frame diesel generator set

What power rating does this generator set provide?

This unit is rated 20 kW prime / 22 kW standby (25 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 20 kW set is available on Cummins, Perkins, Weichai and Yuchai platforms. The engine is matched to the alternator at the 20 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 20 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 not normally required at this rating.

Can the voltage and frequency be customised?

Yes. 380/220 V and 50 Hz are the published standard for the 20 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 20 kW unit can be ordered for a standalone site; where load growth or redundancy is expected, parallel operation is not normally required at this rating. Other ratings in the 10–3,750 kVA range are quoted per project.

How is the quality of each unit assured?

Every 20 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.
