The lamps can be fitted with various types of end fitting from our catalogue, or equipped with customer special fittings, cables or pins. In medium-pressure mercury lamps, a plasma that emits UV light is generated by applying electrical voltage. Unlike most other UV sources, the medium-pressure lamp (MPL) has a polychromatic spectral distribution from 190 nm up to the infrared spectrum. This means that one high pressure lamp may be able to replace 6 – 16 low pressure lamps resulting in lower costs. It is because MP UV lamps emit significantly more UVC energy than LP UV lamps allowing systems to have a higher flow rate of water and/or fit in extremely compact footprint areas. From our broad lineup of 500 W to 35 kW class lamps, we can offer optimum irradiation solutions to bolster your productivity and improve yields. Lamp is designed to provide high radiant energy in the ultraviolet region. Basically, this lamp discharges gas when heated or cooled. However, DR. FISCHER UV emitters frequently achieve more than 4,000 hours of life. Typical applications are curing of inks and varnishes, disinfection of drinking and waste water, ballast water treatment on ships, applications in the food and beverage industries, or chloramin- reduction and disinfection of swimming pools. China Medium Pressure Mercury Lamp manufacturers - Select 2020 high quality Medium Pressure Mercury Lamp products in best price from certified Chinese Led U Lamp manufacturers, LED Street Lamp suppliers, wholesalers and factory on Made-in-China.com By adding dopants such as iron, gallium or indium the spectral radiant power can be significantly varied. Medium-pressure mercury-vapor lamps, the lines from 200–600 nm are present. When a mercury vapor lamp is first turned on, it will produce a dark blue glow because only a small amount of the mercury is ionized and the gas pressure in the arc tube is very low, so much of the light is produced in the ultraviolet mercury bands. The metal halide UV medium pressure lead doped lamps emit UV radiation with peak emission in the UVA range at 357 nm and 420 nm. - As another example, you find also 400W medium pressure mercury UV lamps (arc tubes) which burn in any position (not only horizontal), which are 31mm arc length, 14mm dia, and burn at 3,5A, 125V arc voltage, and roughly the same UV spectrum, but have no starting electrode. UV output is approximately 18 -20 percent of the lamp wattage. Philips Medium Pressure Mercury lamps contain sophisticated quantities of mercury bromides, providing a self-cleaning halogen cycle, to control the depreciation of UV radiation over lamp life. May it be even partially or barely successful. The mercury vapor lamp is a high intensity discharge lamp. Lamp is designed to provide high radiant energy in the ultraviolet region. The metal halide UV medium pressure iron doped lamps emit UV radiation with peak emission in the UVA range at 366 nm and 440 nm. The first mercury medium pressure UV lamps were developed at Heraeus in 1904. The lamps can be constructed to emit primarily in the UV-A (around 400 nm) or UV-C (around 250 nm). They emit a multiple Selected phosphors are used, which are then excited by mercury spectral emission lines. Custom-made lamp sockets ensure trouble-free installation and safeguard your after-sales market. Mercury vapour pressure is typically around five atmospheres and the discharge dissipates between 10 and 100 watts per centimetre of arc length. On top of that, we will stay at your side to provide continuing support.

Spectral output The lamps emit a wide band spectrum in the UVC range. MPUV lamps emit significantly more UVC energy than LPUV lamps allowing systems to have a higher flow rate of water and/or fit in extremely compact footprint areas. Most of the mentioned sources do not present a significant exposure to UV radiation under normal use, but electric welding arcs and some other arc lamps are strong sources of UV radiation. Two major types are differentiated by the mercury vapor pressure in lamp operation. This allows lamp efficiency to be optimised for disinfection, oxidation or photochemistry. Mercury Vapour lamps operating at medium pressure and with arc tubes of aluminosilicate hard glass are classified as the MA style.This was the first commercial kind of mercury lamp which was mass produced for general lighting. UV medium pressure mercury lamp. The primary use is in the waste water disinfection and ship ballast water systems. These devices exhibit the best characteristics of both xenon lamps and high-pressure mercury lamps. Another advantage of MPUV’s is that they produce a polychromatic (emission of multiple wavelengths) output. The fundamental purpose of the photocatalytic reactor is photochlorination, water treatment, chemical degradation, hydrogen generation. This coating covers more than 70% of the diameter of the lighted length of the lamp. [32].Butyl methoxy dibenzoylmethane was irradiated for 100 h in a quartz immersion well photoreactor, equipped with a medium pressure mercury vapor lamp; analysis by GC-MS showed that the total photodecomposition of Butyl methoxy dibenzoylmethane had occurred. The photodegradation of Butyl methoxy dibenzoylmethane was investigated in cyclohexane by Roscher et al.
