The pressing case for solar installations
London Fire Brigade’s Training Centre where the installation of LightSpot controls has resulted in a 25 per cent reduction in the electricity bill.
£1/4 million
annual reduction in electricity bill
The installation of Ex-Or lighting controls has had a dramatic impact in reducing electricity bills and cutting the carbon footprint at various London Fire Brigade sites.
One of the first installations under this contract took place at LFB’s main training centre in Southwark. The installation of Ex-Or lighting controls throughout the complex resulted in a 25% reduction in the electricity bill.
At 7,700 sq m, the specialist training centre is one of the largest buildings in LFB’s estate. LightSpot presence- detecting lighting controls were installed in all parts of the centre including training suites, open plan and cellular office areas, sports hall, storerooms, classrooms, corridors and the reception area. The discrete LightSpot controls with integral photocells automatically switch lights on and off by monitoring the presence of occupants and by measuring the amount of natural light available. Different types of LightSpot are employed according to the size and type of area being controlled. Individual detector types have ranges varying from 6 metres to 60 metres. Regardless of the size of area monitored, LightSpot detectors ensure lights automatically switch on when areas become occupied, and automatically switch off when occupants leave.
Said lan Shaw environmental and energy officer for London Fire Brigade: “Typically, lighting accounts for around 70% of the electricity load at each fire station. The average lighting bill per station is £10,000 and the typical saving made as a direct result of the installation of lighting controls is around 20%. So to date, we are achieving annual savings of £120,000. “Once the entire estate has Ex-Or’s equipment installed, we will be making savings of almost quarter of a million pounds each and every year. “Not only is lighting control saving significant amount of public expenditure, it is also helping us meet our environmental responsibilities.”

The installation of solar panels for domestic heating and hot water is growing business for contractors. There are currently 20,000 British homes with such panels or photovoltaic tiles and this is set to rise with government grants and rising fuel bills encouraging more and more people to consider the option. Now installers can benefit from the speed, convenience and reliability of Conex >B< Press fittings, specially designed for solar installations.
Conex >B< Press Solar fittings are the ultimate in speedy, reliable fitting of copper solar pipes without the need for solder, adhesives or any other jointing material – the perfect flame-free system. They are ideal for solar systems with vacuum and high vacuum tube panels as well as district heating. They are suitable for continuous operating temperatures within normal parameters and short term excursions even higher (glycol: water 50:50).
Conex >B< Press Solar are compatible for use with copper tube to EN 1057 (R250 or R290). They are tested and approved by SPF (Solartechnik Prufung Forschung), the internationally acclaimed research organisation in Switzerland.
Unlike other crimp fitting systems on the market, Conex >B< Press Solar benefits from a 3-point press fixing system – two presses either side of the bead and one press crimping the o-ring. This provides a more secure joint than the 2-point press offered by alternative systems. Using a special Conex mechanical press tool the joint is permanently made and the fitting cannot be dismounted or re-used.
The fittings contain a high quality green FKM O-ring with unique pressing indicator which is suitable for working pressures up to 10 bar, a fail safe function to check systems for leaks. The specially designed O-ring has a reduced section at two points. This causes leaks at low pressures (from 0.1 to 5.0 bar) when the fitting has not been pressed. When the fitting is crimped, the O-ring material compresses, filling the gaps and securing a leak-free joint. This allows installers to check the system at low pressure to ensure that all the fittings have been pressed and correctly fitted.

Powerful partnership
Riello UPS, Europe’s leading manufacturer of uninterruptible power supplies (UPS) has just signed an exclusive distribution deal with Vycon, the world’s leading flywheel energy storage systems designer and manufacturer.
The relationship allows Riello UPS to supply the innovative and highly efficient Voltage Direct Connect (VDC) flywheel in Europe, the Middle East & Africa (EMEA). The VDC flywheel will complement the traditional lead acid battery sets used in Riello’s range of UPS systems for protecting mission critical applications. The VDC flywheel is the latest generation in flywheel technology and provides a reliable, low-maintenance alternative (or addition) to battery sets. During a power failure or disruption, the Vycon VDC flywheel provides a clean, short supply of DC power to a Riello UPS system until the source of power is restored – either through the mains, an emergency generator, or for extra resilience a battery set.
Roberto Facci, commercial director for Riello UPS, said: “The agreement with Vycon strengthens the range of solutions that Riello UPS is capable of offering its clients.
“The technology of the VDC, due to its
reliability, reduced total cost of ownership (TCO) and environmental sustainability, is of great interest to numerous business sectors, from finance and banking, healthcare, computer services and data centres.
“The integration of these systems with Riello UPS solutions will therefore constitute a real advantage for our clients”.
Environmentally friendly, reliable and highly efficient (up to 99.4%), the VDC flywheel energy storage system also boasts a compact footprint and requires minimal maintenance making it an ideal solution for applications and installations where continuous power is essential.
