The silent generator range has been designed to work in locations with greater acoustic restrictions – they guarantee a noise level of around 60dB(A)@7m. These are best designed for the events sector, especially in the urban areas. They have slow levels of sound emissions thanks to a more optimised design of the air intakes and outputs.
Features:
- 20 – 550kVA Single/Three Phase Generators
- 1,500 R.P.M
- 50Hz models
- Wide range of options built for your demands
- Installation, Service & Maintenance available

Industries across the UK rely entirely on an uninterruptible power supply to get the job done, from data centres and hospitals right the way through to defence and utilities. As wonderful as generators are for businesses and organisations, when things go wrong and you need emergency backup power, their decibel level can sometimes be a problem. If you’re operating in an industry that demands optimum acoustics then a heavy range or industrial generator – for example – may not be the best solution for you.
Here at Dale Power Solutions, we have a wide range of silent generators that have been optimised to ensure minimal audio disruption while still providing you with a power supply that you can rely on should the worst happen and you need backup power fast.
From the HRYW-35 T5 S+ and HRYW-45 T5 S+, right the way through to the HRFW-310 T5 S+, HRFW-160 T5 S+ and the HRFW-200 T5 S+ – we have a silent generator for you. All of them come with varying voltages and power factors that can help ensure operational continuity should a power failure occur.
From the moment you get in touch with our team, we’ll be able to create a bespoke silent generator solution for your organisation or business. Expect guidance and advice right the way through as well as regular maintenance, support and spare parts should you need them.
A silent generator solution is the best of both worlds. It provides you with all the power you’d expect from normal diesel generators but, thanks to its optimised air intakes and outputs, noise levels are kept around 60dB(A)@7m.
Our vast range of Himoinsa silent generators can keep noise levels low and offer reduced engine emissions and fuel consumption. We are proud to be a Premier Dealer of Himoinsa generators and are delighted that they are our power supply generator of choice.
All your silent generator requirements can be taken care of in areas such as Pen y Cymoedd, Glasgow, London, Manchester or Scarborough, as well as the rest of the UK. For more information about our silent generator rental, silent generator hire and silent generator purchases, or any of the other diesel generators that we supply, be sure to get in touch with us here at Dale Power Solutions by phone on 0330 999 3000, online or by email at sales@dalepowersolutions.com.

3 Reasons Why Silent Generators Are Useful
Silent generators such as the Himoinsa generators that we offer have several useful benefits to businesses, sites and facilities across the UK in places such as St Albans, Edinburgh and Birmingham.
Outdoor events such as festivals, weddings or concerts all require some sort of power source to ensure electrical items such as cooking equipment, amplifiers and outdoor screens can operate and function properly. A noisy power generator whirring away in the background is not ideal and can completely ruin the event if all the guests are thinking about is the sound of a generator. Silent generators eliminate this problem while still giving you the power supply needed to successfully host an event. Even with indoor venues, a quiet generator is preferable in the event of a power cut. A loud generator, while satisfying your power needs, can cause irreparable reputational damage if the occasion is ruined as a result.
In places such as hospitals or outdoor camping sites, the need to maintain a quiet ambience, be it for recovery or pleasure, is important for health and customer experience. Silent power generators can provide all the power necessary without ruining an ambience.
The threat of a power outage is too great not to invest in a generator and a silent generator is a perfect option if atmosphere and ambience are just as important to your business as the power itself. Our Himoinsa silent range generators come with 100mm thick rock wool which soundproofs the canopy and offers high soundproofing levels.
You might need a silent running diesel generator to operate within the law. Construction firms working in built-up areas such as cul-de-sacs or apartment blocks may use a silent generator to avoid angering residents or breaching decibel levels of that particular local area. The sound of power tools and general construction noise is loud enough and in some places, there are laws and regulations in place that prevent decibel levels from going over a certain point. A silent generator helps construction firms and labourers get on with the job, enjoy continuous power and avoid a backlash from residents or the law.

The Benefits of Silent Range Generators
Quiet Power: The appropriate power level, without the noise
An obvious one but the fact that these quiet generators produce a steady supply of electricity during power cuts at a minimal decibel level, is a real plus point. A large, distracting generator can harm your business if you’re in a customer-facing industry like hospitality. Enclosures on a silent generator are designed to be soundproof, therefore, they only create a fraction of the vibrations that their regular diesel generator counterparts do.
Fuel Efficiency: Emergency backup power that’s cost-effective
A silent diesel generator is much more economical to run because of the viscosity levels of the fuel that it runs on. The way a generator like this operates greatly reduces total fuel consumption. Also, quiet generators produce far more electricity per litre of diesel over their runtime, compared to petrol, which makes them an efficient solution if fuel cost is important to you.
Reliable: Electrical power that stands the test of time
Sturdy, strong and silent. Quiet generators, such as the Himoinsa ones you can find at Dale Power Solutions, are built to withstand all sorts of weather conditions as well as the general wear and tear that comes from working in outdoor or construction environments, thanks to the special seal that prevents water and dust getting in. This can give you peace of mind knowing you’ve invested in the right generator.
Low Maintenance: Hassle-free quiet generators
The Himoinsa silent generators that we can provide your business or organisation with are built without spark plugs. Not having spark plugs present in a generator means that they don’t have to be replaced which reduces the need for overall maintenance.

Generator Maintenance & Services
We have a range of generator services and maintenance options that can help keep your silent generator running at an optimum level. They include:
- Diesel Generator Service & Maintenance: To ensure your silent generator can run at peak power when it counts we recommend carrying out regular maintenance, inspections and repairs if needed. From coolant cleaning and recycling radiator cleaning right the way through to fuel management, OFTEC qualified fuel tank inspections and exhaust treatment, all of these solutions can help keep your silent generator at peak power performance.
- Load Bank Testing: This type of test makes sure that your silent generator can operate at its kW output. A load bank test will let you know if your generator can still run properly, at maximum output, in an emergency. A test of this nature allows us to prioritise maintenance and take preventative action to stop the generator from developing serious issues.
- Control System Management: This element of your silent generator determines how power behaves and responds in different situations. Our team has the skills to manage your entire power control system to make sure it’s always running when you need it. If needed our team will go in and make adjustments to ensure any power problems are avoided.
- Remote Monitoring: Remote generator monitoring avoids the risk of human error and makes sure that your silent generators’ critical loads are always protected from harm. We’ll be able to check the status of your systems from a computer or smart device at any location with an internet connection. We pull a great deal of functional data from these and can create reports. This digital technology can also access vital operating elements of your generator such as its oil pressure, temperature, total run time and if needs be, it can remotely stop and start your generator – giving you peace of mind knowing you’re always in control.
- Generator Spare Parts: From air filters, cooling systems, generator batteries, and generator battery chargers right the way through to generator waste pumps and generator fan belts, here at Dale Power Solutions we’re able to supply all of this and more. We have the parts identification process and cutting-edge ordering software in place so that you always have access to the highest quality spare parts for your silent generator. Designed to precise specifications and built to be durable, dependable and productive, our spare parts are all from genuine generator manufacturers and are certified to industry standards.
- Generator fuel maintenance: Your silent generator is only as good as the fuel you put in it. Clean diesel fuel is needed to ensure everything goes well when your generator is on. Our team can sample, test and treat your fuel to ensure it is not affected by the ultra-fine tolerances and high fuel-injected pressures that diesel goes through.
