Diesel generator set DEUTZ GENKRAFT GK-DZ 20–750 kVA

Need one supplier able to cover almost any power requirement, from a small load to a large industrial site? A 350 kVA GENKRAFT generator belongs to an exceptionally broad 20-750 kVA range designed to cover almost any requirement, as either standby or prime power.

It is one configurable product across the entire range: choose the power rating, enclosure and options. A 350 kVA generator delivers stable three-phase power at 400 V and 50 Hz, with prime and standby ratings, and can start automatically on grid failure while handling demanding motor starts.

Advantages of a GENKRAFT industrial diesel generator

• Configurable 20-750 kVA range: choose the right power level, from the smallest to the largest rating in the line, without paying for unused capacity.

• Prime and standby ratings are stated in accordance with ISO 8528, so you know exactly what a 350 kVA generator delivers in each operating mode.

• Stable three-phase supply at 230/400 V and 50 Hz, matching the Romanian grid standard and suitable for motors and sensitive equipment.

• Automatic start on mains failure with an optional ATS panel, so a 350 kVA generator takes over the loads without human intervention.

• Three configurations: open for a technical room, soundproof enclosed for outdoor installation, and containerized for a fully independent installation.

• Liquid-cooled diesel engine and brushless alternator with 100% copper windings, components selected for reliable operation and dependable starting.

• CE marking and conformity documentation, making the 350 kVA generator eligible for projects financed with European funds.

• Direct-supplier pricing without the markup of an expensive brand: you pay for the technology and components, not the name on the enclosure.

Technical specifications for the 350 kVA generator and the rest of the line

A 350 kVA generator is part of a unified product line: the power rating changes while the platform remains the same. The values below are actual prime and standby ratings. Exact dimensions and weight are confirmed in the technical datasheet for each power step.

How to choose the right power

Sizing starts with the loads the generator must support: process lines, motors, pumps, refrigeration systems, ventilation, lighting and IT equipment. Add their power requirements, then include a reserve for motor starting currents, which can briefly be several times higher than nominal current.

Do not oversize excessively: a generator operated for long periods at too little load does not work at its optimum point. Send us your load list and we will size the correct rating from the 20-750 kVA range and tell you whether a 350 kVA generator covers the requirement or whether the adjacent rating is more suitable.

Operating mode and autonomy

ISO 8528 defines prime power (PRP), available for an unlimited number of hours per year, and emergency standby power (ESP), available for a limited number of hours without overload. This line is rated for both, so it can operate either as the main source or as backup.

Autonomy depends on tank capacity and load. The integrated tank covers a typical standby duty, while extended operation can use a larger tank or external fuel supply. Diesel consumption at 75% and 100% load is stated in the datasheet for each rating.

Why diesel

For industrial power levels, the diesel engine remains the solution with the best balance of cost, autonomy and reliability. It offers high energy density, controlled fuel consumption under load and durability in intensive operation, unlike petrol generators, which are limited to lower power levels.

Unlike a UPS, which covers only a few minutes, a diesel generator can support the load for hours or days as long as fuel is available. That is why it is the standard backup choice for buildings, industry and critical infrastructure.

Components and construction

The technical platform is common across the entire line: liquid-cooled diesel engine, brushless alternator with 100% copper windings and automatic voltage regulator, digital controller with protections, and a frame with anti-vibration mounts for stable installation.

Components are selected for continuous operation and easy spare-parts support. A generator built on a unified platform is easier to maintain and troubleshoot, regardless of the selected power rating.

Configurations and options

Each 350 kVA generator is supplied in the configuration suited to its installation site: open for a technical room or hall, soundproof enclosed for low-noise outdoor installation, or containerized and ready to position, with external access to the control panel.

Options include an ATS automation panel for automatic mains-generator transfer, an extended fuel tank for greater autonomy, industrial sockets and a remote monitoring system. The three-phase output connects directly to the installation's main distribution board.

Applications and industries for the 350 kVA generator

A 350 kVA generator is used in factories, commercial buildings, hospitals, hotels and data centres as a standby source for the entire installation. When the grid fails, it automatically takes over critical loads, from lifts and ventilation to medical equipment and process lines.

Because the range starts at 20 kVA and extends to 750 kVA, the same family covers both a small workshop or farm and a continuous-production hall. Lower-power industrial diesel generators can supply an office, while the larger ratings support heavy industrial processes and refrigeration systems.

For 24/7 facilities, a 350 kVA generator becomes part of the business-continuity plan. See the full GENKRAFT diesel generator range for other series and power ratings, or request sizing from the GENKRAFT technical team. The equipment carries CE marking in accordance with the applicable requirements of the Machinery Directive 2006/42/EC.

Whatever the application, a 350 kVA generator delivers the same stable three-phase power, with optional automatic starting and a configuration selected for the installation site. A common technical platform across the 20-750 kVA range means shared parts and predictable service.

As a reseller, we prepare every order to the selected configuration: power, enclosure, voltage and options. Delivery time therefore depends on the configuration and is confirmed in the quotation together with the final price.

At delivery, the equipment comes with CE marking and conformity documentation. On request, we provide the technical datasheet and certifications required for a financing file. Electrical connection and commissioning are performed by an authorised electrician in accordance with the site's electrical design.

How it works

A 350 kVA generator follows a simple sequence from mains failure to restoration:

1. The mains sensor detects loss of supply or a voltage deviation in the public grid.

2. The ATS automation panel commands the diesel engine to start and disconnects the mains.

3. The generator reaches rated speed and the alternator delivers stable three-phase voltage.

4. Within a few seconds of the outage, the ATS transfers the load to the generator without human intervention.

5. When mains power returns, the system transfers the loads back and stops the engine after the cool-down period.

6. The digital controller monitors operating parameters and shuts the set down on protection events, with an alarm log.

Frequently asked questions

What is the difference between prime and standby power for a 350 kVA generator?

Prime power is the continuous rating available for an unlimited number of hours per year; standby is the emergency rating for a limited number of hours, without overload. The 350 kVA generator is rated for both according to ISO 8528, as shown on the datasheet for each power step.

What power range does the range cover?

From 20 to 750 kVA, one of the broadest ranges on the market. Choose the appropriate rating, from a small load to a large industrial site, all within the same product family.

Does it automatically take over the loads during a power outage?

Yes. With an ATS automation panel, an industrial diesel generator starts and transfers the load within seconds of a grid failure, then automatically returns to mains power. The ATS is optional and is specified in the quotation.

What configurations are available?

Open for a technical room, soundproof enclosed for low-noise outdoor installation, or containerised at higher power ratings. A 350 kVA generator is supplied in the version suited to the installation site.

What maintenance does it require?

Basic maintenance means checking the oil, filters, coolant and battery at the intervals specified in the manual. The digital controller provides early alarm indications, and regular maintenance ensures a long service life.

Can it be monitored remotely?

Yes, optionally. With the monitoring module, generator status, fuel level and alarms can be viewed remotely over the network, which is useful for unattended sites.

How do I order and receive a quote?

Choose the power rating and configuration, then request a quote. We confirm the configuration, price and delivery time. Because each unit is prepared to order, you receive exactly the version suited to your project.

What is the noise level in the enclosed version?

The soundproof enclosure significantly reduces noise compared with the open version, allowing the generator to operate near the building. The exact dB(A) level at 7 metres is stated in the technical datasheet for each power rating.

Do you deliver nationwide?

Yes, we deliver throughout Romania. Electrical connection and commissioning are performed by an authorised electrician in accordance with the site's electrical design, and we provide the required technical documentation.

Is it eligible for projects funded by European funds?

Yes. The equipment comes with CE marking and conformity documentation, so it can be included in co-financed investment projects. On request, we provide the technical datasheet and certifications for the financing file.
