Site Power/Lighting/Generators
The Future of Power One definition of the verb ‘power’ is ‘to provide energy to operate something’. This is a continual challenge to mankind and even more so in these days of environmental awareness. Producing electricity cheaply and efficiently is becoming increasingly important as fossil fuel stores become depleted.
One of the most modern, practical sources for energy is the fuel cell. Fuel cells generate electrical power quietly and efficiently, without pollution. Unlike power sources that use fossil fuels, the by-products from an operating fuel cell are heat and water. A fuel cell is an electrochemical energy conversion device. It converts the chemicals hydrogen and oxygen into water, and in the process produces electricity.
The other electrochemical device that we are all familiar with is the
battery. A battery has all of its chemicals stored inside, and it converts those chemicals into electricity too. This means that a battery eventually "goes dead" and you either throw it away or recharge it.
With a fuel cell, chemicals constantly flow into the cell so it never goes dead -- as long as there is a flow of chemicals into the cell, the electricity flows out of the cell. Most fuel cells in use today use hydrogen and oxygen as the chemicals.
Another type of fuel cell, Photovoltaic (PV) cells, are used in solar panels to convert sunlight directly into electricity.
The USA announced in 2003 its aim to develop hydrogen, fuel cell and infrastructure technologies to make fuel-cell vehicles practical and cost- effective by 2020. Fuel cells are likely to compete with many other energy conversion devices in the future, from gas turbines to the battery in your laptop. They are already used to power large generators and phosphoric-acid fuel cell has potential for use in small stationary power-generation systems. So watch this space to see how this technology could affect you business in the future.
Site Power from PRAMAC Driven in part by legislation but also by the need to exceed customer expectations in terms of functionality and quality, PRAMAC’s 5kVA site generator has steadily evolved. For example, in 2001 the S Class open sets (producing 75dBA at 7metres) were replaced by the fully canopied C6000 with a reduced noise level of only 67dBA at 7metres. The process of developing this generator was driven by EU legislation on noise regulation, but PRAMAC, with an eye to the future, saw the potential for an even quieter generator. Three further years of development led to the launch of the P6000s (see figure i). It’s noise output was measured at 58dB at 7metres - an incredible 23% improvement on the original S class! Figure i – P6000S
In addition to the quieter canopy, maintenance access was improved, so the PRAMAC 6000s is even easier to service. The canopy opens to provide easy access to the engine and alternator, with filters and fuel tap within easy reach of the fitter. In 2011 the socket panel was upgraded to include a 32amp 230v output, along with the 16amp 230v, 2 x 16amp 115v and 1 x 32amp 115v sockets. PRAMAC have also developed a fully galvanised Road Towable lighting rig offering 4 x 400w metal halide flood-lights (the Mighty-Lux – see figure ii below) to be used with the P6000S. The lightweight unit has a 6 metre mast which drops to 2.3 metres when closed. It can be stored in a garage or standard container, and is easily towable by car or light van. By developing
a simple bracketing system by which the P6000S can be dropped into or lifted out of the Mighty-Lux chassis, PRAMAC has given users the opportunity to extend the usefulness of their P6000S fleet. The P6000S sits within a comprehensive range of site generators ranging from smaller petrol units of around 2.5kVA up to 250kVA 1500rpm generators.

Defender Luminator The impressive Luminator mast light from Defender Power & Light is a fully portable 1kW metal halide lighting tower that delivers 100,000 lumens of bright white flooded light in a 360° spread. Fitted with a long life metal halide lamp it delivers up to 7,000 hours of vivid light. The retractable motor-driven telescopic mast is made from corrosion-resistant aluminium. The light head operates between 1.5 – 4 metres and can light half a football pitch.
The robust and durable roto-moulded polyethylene body ensures protection from damage typical of hire use, providing an extended working lifetime. Three screw ‘n’ lock outriggers enable the unit to be used in blustery outdoor conditions making it capable of withstanding winds up to 65mph.
The Luminator runs on an 110V supply and comes complete with a power take-off socket to link compatible tools and equipment, reducing the need for an additional power supply.
