Businesses and homes across the world over rely on clean-burning, efficient, quiet diesel generators for standby power, emergency power and as a main power supply. Some rely on diesel generators to ensure the power to their critical systems is uninterrupted in the event of electrical cuts, whilst others operate in areas poorly served by the electrical grid or on a remote basis where power has to be generated on-site.

Stand By Power for Homes

Large residential buildings and even individual homeowners can protect themselves against the inconvenience of occasional power cuts by installing a standby power generator in or near to their home. Power from generators can be fed directly to the home and act in the same way that normal mains electric does. Things such as lighting, appliances and equipment will continue to run smoothly.

Stand By Power for Businesses

Having a reliable emergency power generator will provide you with more than just peace of mind and it’s actually a necessity for businesses to invest in diesel generators. Using a diesel generator will ensure your power is uninterrupted and that your business continues to run as usual even without mains electricity.

Questions To Ask Yourself

Before investing in a backup diesel generator, there are a number of questions you need to ask yourself. These are listed below:

    • How much income does your operation take in on a daily basis?
    • How much of this absolutely requires electrical power to happen?
    • How many of your assets depend on electrical power to hold their value?
    • How much does it cost to close and restart your business?
    • How many power cuts or electrical issues have you suffered from in the last 5 years?

The information gathered from these questions will help you to make a more informed decision over whether you need a diesel generator or not.

Diesel Generators as Main and Continuous Power Supply

Some commercial and industrial businesses rely on diesel generators as their main power supply. This is generally when power is needed in a remote location or for critical systems that demand regulated power. Generators are consider a main power supply when they are used for more than 8 hours on a daily basis. Continuous is when they the power is used on a 24 hour basis, 7 days a week. Remote locations will typically use continuous power supply as they won’t have access to mains power.

Choosing A Generator

Choosing the best type of generator can be difficult and our team at Bellwood Rewinds will help you to choose the best one for your requirements. Diesel generators are one of the most effective and best types of generators for both home and business owners.

What To Do When The Power Fails

What do you do when the power fails? Are you a traditionalist that relies on candles and for the power to come back on or are you prepared so you can continue life as usual without interruption. Having a back-up power supply means you don’t need to worry about losing access to the internet or your freezer defrosting.

Power Cuts Affect Everyone

The electrical grid serves everybody, from homeowners to farms, meaning we are all at risk of suffering from a power cut. Whilst power cuts are usually quite uncommon in built up areas, they can have a detrimental affect; especially on businesses. People living in rural areas and on farms are likely to suffer from power cuts.

Understanding how the power grid works and and the factors that contribute to power cuts will help you to make a more informed decision about whether you need a backup power supply or not. The basis of the electrical grid are:

  • Power Generation – Large generators produce high voltage electricity, these generators can be steam driven by fossil fuels or nuclear power or water driven by dams and rivers.
  • High Voltage Lines – The high voltage is then transmitted through these lines to substations.
  • Sub-Stations – Substations receive high voltage from power plants and then step down the voltage using transformers.
  • Poles and Transformers – The transformers then receive the voltage from the substation and step it down again for residential use.
  • Industry Substations – Some factories and larger industries have dedicated substations. These substations can step-down the high voltage to various different levels dependent of the industries requirements.

This type of structure is often referred to as an electrical infrastructure. Each part of this infrastructure is part of a chain, and if a part of the link is broken then the system will fail.

A Proactive Approach To Power Cuts

There a re a number of things that can cause power cuts. Both nature and human error can cause the electrical grid to fail. No matter what the cause might be, the result is the same when one part of the grid fails you’ll be left with no power. Isolated damage caused by the weather can be repaired quite quickly or rerouted to avoid disruption. However, substation failures or line damage can have much longer repair times, meaning you’ll be left without power for much longer.

Be Prepared With A Backup Generator

It’s impossible to tell when a power cut is going to happen. So one of the best defences against a power cut is to be prepared with a backup generator. One of the best backup power options for both individuals and businesses to use is a diesel generator. Medical facilities, farms and catering facilities will usually have emergency power ready to kick in, should the mains electricity fail. If you think you mightn’t need one that often then a used one, can provided a much more cost-effective backup generator option.

There is a lot to learn about diesel generators based on their nature, uses, reliability etc. Although some of this information is true there are many misconceptions about diesel generators which still prevail among people.

We’ve list a few of these common misconceptions below.

Diesel Generators Make A Lot of Noise…

Modern generators have been designed in a way that they are quieter, yet still provide you with a lot of power. Innovative technology used in the manufacturing and the new standard of diesel fuel have allowed diesel generators to work with less noise. This means you don’t have to worry as much about sound pollution and its effects.

They Aren’t as Reliable…

Generators are always fully tested, and providers will not sell them if they fail to provide the expected services. Some people think that diesel generators break down frequently, make choking sounds whilst starting or repeated calls for damaged parts. Bellwood Rewinds always make sure that our customers are being offered diesel generators that are in good working order and live up to their expectations.

They Cause Environmental Pollution…

Generators used to be smelly and smoky, they used to emit toxic gasses leading to air pollution. However developments in modern technology have solved the problem by reducing pollution and becoming more efficient.

They Occupy Lots of Space…

Modern generators are heavy, but a lighter in comparison to older generators. Diesel generators are more compact and can be easily moved using any mode of transport and shipped all over the world. Their dimensions are small when compared to older generators in turn occupying less space in the room.

If you are looking for an efficient diesel generator company, then Bellwood Rewinds is one of the best companies in the UK. Their expert team will assist you in choosing the right unit for fulfilling your requirements.

If you’re not familiar with diesel generators you may be wondering what they are and how they work. A diesel generator is the combination of a diesel engine and an alternator or electric generator which is used to generate electrical energy. The alternator is the generator which generates the electrical power, whereas the engine is used to rotate the electrical generator, however diesel generators are mostly used as an emergency power supply.

The Working Principle

Diesel generators work in four cycles:

  • Suction/ Intake
  • Compression
  • Power
  • Exhaust

The working principle of a diesel generator is based on the law of Energy conversion i.e. “Energy can neither be created nor be destroyed but be only converted from one form to another form.” Diesel has a chemical energy, during combustion the chemical energy is converted into heat and force. This force is known as mechanical energy which helps in rotating the alternator. The combustion is processed by a spontaneous ignition of the fuel when injected into a highly compressed charge of air which has reached around 750 degrees Celsius.

Suction Stroke

The piston moves from the centre due to the inlet valve opening, the air is then drawn into the cylinder. When enough air is drawn with pressure the suction valve gets closed at the end of the stroke.

Power Stroke

Fuel is inserted into the hot compressed air, it starts burning and then maintains the pressure, when the piston reaches the top centre the supply of fuel turns off. The injection of the fuel at the end of the compression stroke continues until the cut off point. The inlet and the exhaust valve remain closed and the hot gases and compressed air now expand in the cylinder which causes the piston to move down until it reaches the bottom dead centre.

Exhaust Stroke

During this stroke, the piston again moves up and allows the exhaust valve opens forcing the inlet and fuel valve to become closed. The burnt fuel gases escape due to their own expansion, the remaining gases are pushed out by the upward movement of the piston through the exhaust valve. When it comes to the end of this stroke, the exhaust valve closes, and the cycle is completed.

Diesel Generator Parts

Below are the following components of a diesel generator:

  • Engine
  • Alternator
  • Fuel System
  • Governor
  • Voltage Regulator

Assembly & Montage

No matter if you buy or hire a generator, the equipment will never reach you completely unassembled. The main generator will arrive pieced together, meaning you just might have to assemble the extra parts such as; wheels, support legs, or handles. However, this rarely occurs for customers who hire generators from Bellwood Rewinds, there are two steps you need to take when hiring a diesel generator;

  • Add the necessary amount of oil, most of our generators will show the oil level so you know how much to pour. Please note that the oil level should be checked before every use and changed after about 20 hours of continuous running.
  • Add fuel by following the instructions for your generator’s model. It’s important to make sure your fuel tank isn’t over filled so the air system isn’t clogged.

Diesel Generator Safety

It is crucial to maintain safety always when using your diesel generator, although all our Bellwood Rewind generators are built for safe use it is still a piece of equipment which works with highly flammable substances and needs to be treated with care. Our number one rule when it comes to using our generators is to always keep it outdoors, if you fail to follow this simple rule you can coincide with life threatening scenarios such as carbon monoxide poisoning, or electric shocks. Our other safety rules include;

  • Keep it away from rain and water in general
  • Store your generator fuel in a safe container
  • Always get professional help if something unexpected occurs

The modern diesel generator is far more affordable, improved efficiency and the units are generally quieter this in turn raises the bar on power. Diesel generators are useful in homes, businesses and factories as well as large functions such as wedding and corporate events.

Facts About Diesel Generators

Diesel generators use compression ignition for igniting the fuel. This is when air is drawn into the engine and then heated by a high compression, this then results in a higher temperature within a diesel engine as compared to a petrol in diesel engines, air and fuel are filled into the engine at different stages. Diesel generators are usually more expensive than petrol ones, they need to burn only half the fuel amount as compared to petrol generators to produce the same amount of energy.

Less noise and more maintenance. The fuel which is present in diesel generators usually auto ignites without a spark. It is much safer, with less chance of an explosion. Diesel generators are easy to maintain and have a longer life expectancy compared to petrol ones.

Whether its portable, home, or industrial generators there are many shapes and sizes to choose from. With 5000 watts that can supply power to various small and medium sized gadgets, home generators have the power to supply power to the majority of the house, and as the name suggests, industrial use diesel generators are designed for small to medium sized business organisations.

Purchasing of generators is based on following factors:

  • Power Output: The watts rated can be as low as 5kW which can supply power to multiple appliances. Generators of 30kW can supply power to a medium sized home or business.
  • Run Time: You can select which generator best suits your needs, depending on its run time.
  • Price:The most important factor when purchasing a generator, many people prefer portable generators as they are the cheaper alternative however these generators can only supply small gadgets.
  • Noise: Most generators now make less noise along with providing uninterrupted power. Most generators can be supplied along with an acoustic cover to further reduce noise pollution
  • Reliability: It goes without saying that reliability is an essential factor when purchasing a generator. Cheap generators with low quality will run efficiently, it’s important not to purchase a low standard generator just for the sake of saving money.

Due to the crisis in Syria and the rising tensions of potential war, it is no surprise that the price of petrol and diesel has risen, triggering fears for fuel users that they could see their fuel bills spiral.
Prices had been hovering in the low to mid one hundred and teens pence per litre, were suddenly around 6p dearer, or more.

Why Do I Need Diesel in my Generator?

Diesel is used in generators thanks to the benefits of diesel as a fuel. In diesel powered engines, they work by compressing air in the engine to create power. Compared to gasoline powered with uses a mixture of fuel and air to create energy. This makes the ratios much higher for diesel, and such creating more power. However, one of the main benefits of diesel generators is the fuel efficiency. When you use a diesel generator, you may be able to generate enough power for 48hours usage, off just ten litres of diesel.

What Factors Influence the Price We Pay for Fuel at the Pumps?

The price you pay at the pump is governed by the wholesale price, which in turn is affected by;

  • the global price of crude oil
  • supply and demand for crude oil
  • refinery production and capacity
  • the currency exchange rate of £ to $
  • distribution costs
  • the margin fuel retailers decide to take
  • fuel duty charged by the Government
  • VAT charged at the end of every forecourt fuel transaction

We all know how frustrating it can be when we have a power cut, but what do businesses do when this happens? Power cuts can happen at any time and for any reason, businesses who are prepared have back up systems and procedures in place, most of which include generators.

It may come to as a surprise to you but there are many businesses, even some which you never thought about use back up generators to keep their operations running smooth 24/7 – you would never know if there was a power cut.

Bellwood Rewinds specialise in portable diesel generators can be used for domestic purposes such as powering a home if they run out of power. Industrial diesel generators are regularly used in commercial facilities such as offices, construction sites, nursing homes and other types of businesses and industries.

We’ve listed some of our top industry services and why they need industrial diesel generators for their business;

Hospitality and Tourism

When the power cuts out, these locations need to make sure their guests and residents are safe and secure at all times.

  • Hotels; the use of heating, lights, elevators, security cameras, communication services.
  • Resorts; Restaurants and pool filtrations.
  • Amusement Parks; rides, food storage and prep, and toilet facilities.
  • Zoos; keeping cages locked, temperature of animal enclosures, keeping lights on for guests
  • Casinos; slot machines, cash machines, security cameras and communication systems.


When the power fails these companies can’t afford to lose all of their products due to uncontrolled temperatures and conditions.

  • Distribution Centres; freezers, refrigerators, loading banks and computing systems
  • Bakeries and Catering Centres; ovens and packing equipment
  • Restaurants; stoves, refrigerators, and cash registers

Council Services

  • Water Treatments; pumps, filtration systems, computers, communications

Power Plants and Energy

To avoid running out of power most modern power plants often have generators installed for worst case scenarios.

  • Nuclear Power Plants; most have standby gensets installed for contingency plans
  • Wind Farms; when the wind doesn’t blow many wind farms have a backup generator set in place
  • Solar Power Plants; for when the sun isn’t shining, many solar installations will have a generator back up.
  • Renewable Energy Facilities and Microgrids; systems with combined renewable and energy storage often have generators.

These are just a handful of the many industries that utilise backup generators. Just because you don’t see it, doesn’t mean it isn’t running in the background. You might have even been in a store that had a major power failure and didn’t even notice because their generator kept things running smoothly.
