GermiTron Product Info



  • What are Germicidal Ultra Violet Rays?

    UV Rays are Electromagnetic Light Rays wavelength shorter than visible light rays, typically 152 to 400 nM (nM is Nano Meter, or 10-9M).

    UVA: Wavelength 315 to 400 nM. Marginal or no Bactericidal Properties.

    UVB: Wavelength 280 to 315 nM. Limited Bactericidal Properties.

    UVC: Wavelength 200 to 280 nM. At 253.7 nM has high Bactericidal, Germicidal and Virucide Properties. Adequate dose of UVC at 253.7 nM delivered for adequate time of exposure, destroys virtually all Bacteria & Virus.

    Ultra Low Wavelength UV: Below 200 nM, produces uncontrolled and unregulated ozone in air. Should be prevented in occupied space, as level of ozone may exceed permissible levels.

    What Is the Energy Intensity and Time of Exposure Required to Kill Bacteria?

    Intensity of UVC Energy at 253.7 nM and adequate time of exposure of target bacteria are required to ensure destruction of bacteria to desired level. Both Energy Intensity and Time are essential. If one of these is inadequate, Kill Rate of bacteria cannot be assured.  Kill Rate of bacteria is defined in unit µwsec/cm2. This is different for various bacteria, and is defined by Center for Disease Control (CDC) Atlanta, GA.


    What is the designed Kill Rate for GermiTron?

    The greatest benefit of the GermiTron UVGI System is thas it is custom designed for client defined Kill Rate. See Germitron UVGI Selection Chart. No other system provides such flexibility. No other system guarantees deliverable energy intensity and Kill Rate in quantifiable units. Kill Rate in the GermiTron System is designed on Energy Intensity at end of the lamp life. This guarantees that the designed Kill Rate is provided throughout the entire life of the lamp.


NuClimate is proud to exclusively represent Ruks Engineering products inside the United States.  The Ruks Germitron is the most advanced Ultra Violet Germicidal Irradiation (UVGI) System to assure committed Kill Rate of air borne pathogens in Ventilation Ducts. Ruks GermiTron is the only system that analytically demonstrates kill rate of bacteria in quantifiable units, proven by scientific Selection Graphs. At a Rated Average Lamp Life of 16,000 hours, provides the longest lamp life in the industry. Modern Control and Monitoring System to provide readily visible indications for lamp failure and hours of utilization of lamp life. Optional features with UV Intensity Monitor and Indicator for actual energy delivered. No other system packs these assured operational features and benefits in one. Can be custom designed to deliver project specified Kill Rate.  Scientifically backed Selection Charts available. Ruks GermiTron is the most effective UVGI system in the industry to assure Kill Rate of target bacteria.
