50Hz Generators for Sale from the UK

Generator RPM for 50Hz Explained

One of the most common technical questions we receive relates to generator rpm for 50Hz applications. The generator rpm required depends on the alternator pole configuration and desired output frequency.

For industrial diesel generators designed for continuous or heavy-duty use, 1500 rpm is the industry standard for 50 Hz operation. These slower-running generators typically offer:

• Improved longevity
• Reduced wear on the diesel engine
• Lower operating noise
• Better fuel efficiency
• Enhanced reliability for long running hours

In comparison, some smaller generators operate at 3000 rpm to achieve the same generator frequency. While these can be suitable for occasional or lighter-duty use, lower engine speed models are generally preferred for demanding industrial applications.

Understanding the link between generator rpm, engine speed and output frequency helps ensure the correct generator set is selected for your operational requirements.

50Hz vs 60Hz Generator Systems

The difference between a 50Hz vs 60Hz generator primarily relates to the electrical frequency produced by the alternator. Different countries and industries operate on different frequency standards.

A 50Hz diesel genset is typically used throughout:

• Europe
• Africa
• The Middle East
• Most of Asia
• Many international industrial sectors

Meanwhile, 60 Hz generators are more common in North America and selected parts of South America and Asia.

Using the wrong generator frequency can create compatibility problems with connected equipment. Motors, pumps, HVAC systems and sensitive electrical devices are often designed specifically for either 50 Hz or 60 Hz power supplies.

Choosing the correct generator 50Hz configuration ensures stable performance, proper equipment operation and long-term reliability.

Silent and Open 50Hz Diesel Generators

We offer both silent and open 50Hz diesel generator configurations to suit different installation environments.

Silent generators are available in canopied and containerised designs. These units are ideal where reduced sound levels are important, including residential developments, hospitals, events, commercial facilities and urban construction projects.

Open generators are commonly selected for plant rooms, dedicated generator enclosures and industrial facilities where acoustic protection is already provided externally. Open units often allow easier maintenance access and can be suitable for larger industrial power generation projects.

Our team can help identify the most suitable configuration based on your operating environment, noise restrictions, cooling requirements and installation plans.

Single Phase and 3 Phase 50Hz Generators

We supply both single phase and 3 phase 50Hz generators across a wide range of power ratings.

Single phase generators are commonly used for:

• Residential backup power
• Small workshops
• Light commercial applications
• Temporary site power

3 phase generators are typically required for:

• Industrial facilities
• Manufacturing operations
• Data centres
• Agricultural applications
• Construction projects
• High-demand commercial installations

Selecting the correct output type is essential to match your power requirements and connected load profile. Our experienced team can assist with sizing and specification guidance to ensure optimal generator performance.
