UV Component

Germicidal Lamps  (Quartz Sleeve) 


Ultraviolet radiation in the 200-300 nm range is extremely effective in killing microorganisms such as airborne and surface bacteria, viruses, yeasts and molds.

Pure Casa germicidal lamps are specially designed to produce the highest amount of UV radiation-typically about 90% of the Total rated energy is at 253.7 nm.  This radiation is very close to the peak of the germicidal effectiveness curve of 265 nm, the most lethal wavelength to microorganisms (see graph below). Our germicidal lamps are used extensively in air and water purification applications, HVAC systems (Heating, Ventilation and Air Conditioning), pharmaceutical and semiconductor sterilization applications. In addition, they are used in drinking water, waste water and ground water remediation.


Our VH germicidal lamps generate energy at 185 nm in addition to the 253.7 nm line. This UV emission produces abundant amounts of ozone in the ari. Ozone is an extremely active oxidizer. it destroys microorganisms on contact and acts as a deodorizer. One of its primary advantages is that it can be carried by air into places that the UV radiation cannot directly reach. We design and manufacture lamps to produce various amounts of ozone to meet specific application requirements. Our VH lamps are typically used in the treatment of air, pool and SPA water.
