LightSources offers superior quality vacuum-sealed medium pressure ultraviolet (MPUV or MPHO) lamps for diverse water and air disinfection applications. Medium pressure UV lamp’s are used in a variety of applications from curing (UVA) to microbial disinfection (UVC).
The primary use is in the waste water disinfection and ship ballast water systems. 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. High powered MPUV/ MPHO lamps emit energy over the 200 through 400 nm (polychromatic ) range as well as operating at a much higher temper range of 600 – 900°C.
LightSources offers the ability to customize your MPUV /MPHO lamps to your own specification and application needs. Lamps are available from 100 watts per inch to over 700 watts per inch, with arc lengths ranging from 2 to 85 inches.
Quality Lamp Construction
All of our MPUV lamps are constructed from the finest materials and manufacturing techniques available, including:
- high-quality, ultra-low water content fused quartz,
- hermetic seal using molybdenum foil within a hard quartz capillary
- pure tungsten pin electrodes with an over-wind of throated tungsten.
Each lamp is pumped and filled with an inert Argon gas in an exacting process ensuring total accuracy of fill pressure and mercury content. The lamp is then completed by the use of either a metal or ceramic base and suitable electrical termination. Each lamp has a serial number enabling complete traceability from start to finish in the production and measurement process.
