Why do you need a diesel generator?

A petrol or diesel generator is essential in many circumstances – as a standby generator to your home; as a backup generator to your business, factory or workshop; as a prime power source when you have no easy access to mains power – maybe installing mains power is prohibitively expensive or technically difficult; critical loads also need a secure source of power, normally in conjunction with an uninterruptible power supply to prevent any loss of power to data centres, computer equipment, server racks, telecoms equipment and essential medical equipment.

Smaller petrol generators are often used for mobile catering, markets, building and construction sites and even in remote areas of large gardens – meaning you can use lighter electric gardening tools rather than heavy petrol hedge trimmers and strimmers.

Welder generators are used for repairs and contruction in places where mains power is not available – farming, constructions sites and in marine applications.

Why do you need an Uninterruptible Power Supply?

Uninterruptible Power Supplies (UPS) ensure your critical equipment (normally IT or computer equipment) never loses power at the wrong moment. If power is lost the batteries within the UPS take over the load either instantly, with an ‘Online’ UPS or in a very short amount of time that most equipment can handle – ‘Line Interactive’ or ‘Offline’ types.
