(openPR) - UV Amalgam lamps with a unique coating save time and costs
• Longlife technology doubles operating life
• Potential for savings in design of disinfection equipment

Heraeus is launching at AQUATECH a 800 Watt Amalgam lamp, the most powerful UV Amalgam lamp on the market. The new 800 Watt lamp features the unique Longlife coating from Heraeus Noblelight which considerably extends the operating life of UV lamps.
At the AQUATECH exhibition, which takes place from September 30 to October 3, 2008 in Amsterdam, the manufacturer of special light sources is showing UV lamps which are used for drinking water disinfection in waterworks, for wastewater treatment in sewage treatment plants and for the treatment of industrial process water. These include low pressure UVC lamps, compact, high power medium pressure UV lamps and GoldSpot Amalgam lamps.

With 800 Watts of electrical output and a length of 150 cm, this new development provides more than 30 percent more UV radiation than earlier 600 Watt lamps. Heraeus Noblelight has been successful in optimising the temperature management of the new 800 Watt lamp. The lamp works with active cooling. For the user, this means that the Amalgam lamp is easier to dim and, specifically, can be dimmed from 100 to 40 percent output, while maintaining a roughly constant efficiency of 35 to 40 percent.

The UV lamp also comes with a matched electronic power supply. The digital power supply is computer controlled and can be connected to a PC via an interface.

The 800 Watt lamp can be used in water treatment applications, generally wherever there is a need for high powers. It combines the benefits of medium pressure lamp technology in terms of high power, with the high efficiency of low pressure lamps.

In comparison to the other lamp technologies, UV Amalgam lamps deliver the best combination of efficiency and operating hours. Thanks to their higher power and excellent operating life, system builders require fewer lamps when designing a disinfection system. Consequently, there is great potential for savings, in terms of number of lamps, system components, energy consumption and maintenance costs.

Heraeus Noblelight has succeeded in doing this with the GoldSpot Amalgam lamps by eliminating the transmission loss of the quartz glass associated with conventional UV lamps to achieve a almost constant disinfection effect over the total operating life. With conventional UV lamps, mercury diffuses into the quartz, so that these lamps usually deliver only 50% of the initial UV output after 8000 operating hours. The Heraeus technology allows up to 16,000 operating hours with virtually constant UV output power, which is significantly more power than conventional lamps.
The new 880 Watt Amalgam lamp also benefits from Heraeus Longlife technology.

Ultraviolet light has an intensive effect. UVC radiation kills viruses and micro-organisms such as bacteria, without the addition of chemicals. There are no residual chemicals and the germ count in water and sources of infection are reliably reduced. The physical method of disinfection using UVC light is both dependable and cost-efficient.

Since its development of UV medium pressure technology in 1904, Heraeus Noblelight can look back to 100 years of experience in the development, production and application of UV lamps. Through innovations such as Longlife technology, Heraeus continues to set milestones in the field of UV lamps. Heraeus Noblelight is an original equipment supplier and the partner of choice for many systems builders involved in the disinfection of water, air and surfaces, as well as for manufacturers of systems for photo-chemistry and photo-oxidisation.

Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China, Australia and Puerto Rico, is one of the technology- and market-leaders in the production of specialist light sources. In 2007, Heraeus Noblelight had an annual turnover of 90 Million € and employed 666 people worldwide. The organisation develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical laboratories.
Heraeus, the precious metals and technology group headquartered in Hanau, Germany, is a global, private company with over 155 years of tradition. Our businesses include precious metals, sensors, dental and medical products, quartz glass, and specialty lighting sources.
