FISCHER UV emitters frequently achieve more than 4,000 hours of life. 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. particularly suitable for photochemical processes. Medium pressure systems can be used in plants with higher flow rates (Jesky et al., 2001). 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. The spectral emission depends on the properties of the plasma, such as temperature, pressure and atomic as well as molecular content. Medium pressure lamps emit a broader spectrum of UV than low pressure lamps. The mercury which is present inside the tube is in liquid form (at room temperature) which is ionized before generating light. Medium pressure UV lamp’s are used in a variety of applications from curing (UVA) to microbial disinfection (UVC). Hence, the spectral distribution of a mercury-xenon Lamp includes a continuous spectrum from the ultraviolet to infrared and the strong mercury … The mercury vapor lamp is a high intensity discharge lamp.

We provide a complete setup of the photochemical reactor with chiller and safety cabinet. The Mercury Medium Pressure UV Lamps are appreciated mainly for two applications: For UV curing and drying. Two major types are differentiated by the mercury vapor pressure in lamp operation. 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. This means that one high pressure lamp may be able to replace 6 – 16 low pressure lamps resulting in lower costs. The most common form of germicidal lamp looks similar to an ordinary fluorescent lamp but the tube contains no fluorescent phosphor.In addition, rather than being made of ordinary borosilicate glass, the tube is made of fused quartz or vycor 7913 glass. Medium Pressure Mercury Lamp We manufacture and supply the Medium Pressure Mercury Lamp for the use of photochemical reactors and water disinfectant.

LP, Amalgam LP and MP lamps are mercury based arc lamps, differing primarily by electrical excitation and ionization levels of the mercury within the lamp and corresponding internal pressures. UV medium-pressure lamps feature a broad, pronounced line spectrum in the ultraviolet and visible range (200 nm to 600 nm) and a high power density of about 100 W/cm². This is different from fluorescents which use the mercury vapor arc to create a weaker light that mainly creates UV light to excite the phosphors. 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. In medium-pressure mercury lamps, a plasma that emits UV light is generated by applying electrical voltage. Of these sub-segments, amalgam mercury lamp accounted for over 40% of the total UV mercury lamp segment revenue and is anticipated to remain dominant during the forecast period. Basically, this lamp discharges gas when heated or cooled. For our standard UV lamps (100 W/cm), we guarantee a lifetime of 1,500 operating hours with less than 25% UV radiation decrease. High-pressure mercury-vapor lamps are those lamp commonly used for general lighting purposes.
