CoiloTron 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 CoiloTron?

    The greatest benefit of the GermiTron UVGI System is thas it is custom designed for client defined Kill Rate. See CoiloTron 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 CoiloTron 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 CoiloTron is the perfect Ultra Violet Germicidal Irradiation (UVGI) System to assure mold free cooling coils and drain pans in air handling equipment.  Eliminates mold, fungi, and microbes on cooling coils and in drain pans to keep these components clean and looking like new.  Improves the heat transfer efficiency of the coil up to 20%.  Near 100% elimination of Endotoxins and pathogens and reduces allergy symptoms, SBS and indoor related sickness.  


  • Used for elimination of mold, fungi, and bacteria on cooling coil and drain pan of AHU

    Clean & new looking coil increases heat transfer efficiency. Results in energy reduction

  • Near 100% elimination of Endotoxin and Pathogens on coil

  • Reduces allergy symptoms, SBS and indoor air related sickness

  • Helps obtain LEED and GBC Merit Points

  • Suitable for new or retrofit applications

    High intensity twin UVC lamps per fixture

    High specular, 86 % reflectivity Aluminum surface intensifies UVC rays on cooling coil and drain pan

    Each lamp housed in individual Quartz Sleeve to GE 214/219 spec. Ensures highest transmission of UVC

    Quartz Sleeve prevents direct contact of air on lamp surface. Sustains lamp surface temperature constant to optimize continuous high performance of lamps.
