Generator Suppliers

Diesel generators can be used for many applications. Here are the most common:

Standby: the most common use of a generator. This is to start-up in the event of a mains failure and provides back-up power. It can also be set up to not only start up when the mains fails but to also carry on running when the mains returns. This involves synchronising with the mains and slowly ramping off ensuring there is no break in the supply again.

Prime: When the generator is used as the main power source and is running continually or for extended periods of time.

Peak lopping: very often more power is needed in locations than what is being provided by the mains supply. Upgrading the mains supply can be very costly and this is when you can install a generator to provide the extra power that you need. The generator will sense when the mains supply is near capacity and start the generator enabling it to provide extra power.

Acoustics are a major part of any generator project and need careful consideration when cost and space planning. From carrying out initial acoustic surveys through to the final installation we will ensure your requirements are met.

Acoustic ranges from 85dBA to 50dBA@1m. We offer generators within attenuated plant rooms, drop over, bespoke, or standard close fit canopies and containerised solutions. We can also look after any necessary louvres that maybe required and can supply and install secondary silencers within the flue to reduce the noise further.

Shenton Group can supply SCR catalyst systems to our generators. SCR’s (Selective Catalyst Reduction) may be required if the client is concerned about the exhaust emission produced or is considering to use the generator plant for anything other than standby emergency power. If this is the case then all equipment over a certain size must comply with the new MCPD directive (Medium Combustion Plant Directive). SCR systems reduce NOx emission by the injection of Urea (AD Blue) into the exhaust catalyst system.

In many generator installations, exhaust flues need to exit away from the generator or building location. Shenton Group can supply and install bespoke flue systems including stainless steel, twin-wall insulated and coloured to blend in with architectural surroundings.

Shenton Group manufacture and supply a range of Automatic Mains Failure (AMF)/ Automatic Transfer Switch (ATS) panels and dual mains panels designed for covering life safety equipment that must be backed up from two supplies.

For larger switchgear applications our engineers work closely with all major manufacturers, ensuring that complex control, synchronisation and switching arrangements are fully integrated.

Emergency Standby Power (ESP): Applicable for supplying power to varying electrical load for the duration of power interruption of a reliable utility source. Emergency Standby Power (ESP) is in accordance with ISO 8528. Fuel Stop power in accordance with ISO 3046, AS 2789, DIN 6271 and BS 5514.

Prime Power (unlimited running time): Prime Power is the maximum power available at a variable load for an unlimited number of hours. A 10% overload capability is available for a limited time. (Equivalent to Prime Power in accordance with AS 2789, DIN 6271 and BS 5514). This rating is not applicable to all generator set models.

Base Load (Continuous) Power: Applicable for supplying power continuously to a constant load up to the full output rating for unlimited hours. No sustained overload capability is available for this rating. Consult authorised distributor for rating. (Equivalent to Continuous power in accordance with ISO 8528, ISO 3046, AS 2789, DIN 6271 and BS 5514). This rating is not applicable to all generator set models.

Some engines have better load acceptance or ventilation requirement than others, some alternators have better efficiencies and some control systems are just that little bit more sophisticated than others. Rest assured we will ensure your complete solution is the right choice for your application.

Ventilation is key to any generator installation to ensure that the generator doesn’t overheat. Getting the correct cooling/ combustion air to your generator and discharging air away can be achieved with the use of ductwork ventilation systems and, if required, inline fans can be incorporated into the system.
Flue dilution is when the generator exhaust gases and hot air from the generator engine and radiator are discharged together through one common duct/ louvre. This can negate the need to install a separate exhaust flue, and often provides value engineering and can simplify the install.

Most generators will come with a standard base fuel tank typically offering 10 hours run time at 75% load. However in instances where longer run times are required, space is an issue or where legislation comes into play, you may require a bespoke bulk fuel system.

We offer extended base tanks or bulk fuel tanks with a generator day tank local to the generator. This then gives you the option of going for a fuel transfer system or standard flow and return.
Types of fuel transfer pipework that we specialise in: Powerpipe, welded steel pipe in pipe, Brugg® and underground plastic pipe in pipe.
