Most frequent questions and answers

The radiator lamps require replacement once a year. They are low cost.

The overall unit has a 2-year warranty. Transformer power supply has a lifetime warranty.

UVC Tower is 7 amps @ 120v

This is solely determined by the space that is being cleansed.

No, however it is recommended to have a dark space as it deters people from entering.

No, the bulb / radiator is just a basic glass tube. It needs direct exposure. Glass and other material placed in front will block UV-C output.

Tower and Rack operate in 250-270 Nanometer range. 

Never allow humans to be in direct radiation of UV-C light. Since UV-C is not visible light, the fixtures have safety protocols built-in (occupancy sensors, red glow to indicate they are luminated, audible beep and beacon) to avoid exposure. Many studies have been done on the effects of UV-C and the results show minimal effect in the short term. Studies have shown damage to the eye can be an effect of exposure to UV-C light. It is required that humans and animals not be exposed.

See link from an FDA about the use of UV-C and other items to combat Covid 19. Released in March 2020. The FDA approved a waiver on UV-A, UV-B and UV-C in the 1950’s.  It has recently started recommending the use to combat against virus and bacteria for everyday use, not just high-risk areas such as hospitals. 

User may do minor repairs and lamp replacements. Extensive repairs must need to be done by a trained technician. 

No adverse effect. The product works faster on wet surfaces.

Yes, they can break. The radiators are like a normal fluorescent bulb. Like Fluorescent bulbs, they have Mercury in them at 5%.

A single tower can treat a 40’ x 40’ area in 2 hours, however that number goes down drastically the smaller the space. For instance, a 20’ x 20’ room can be as low as 20 minutes. Nemesis Tower design of photometric overlap allows this quick disinfection range.

We will set up an initial pre-phase design to determine your coverage per area and supply a quote.

The Tower and Rack just need normal wiping down.

Limited effect, although with heavy haze it can reduce the transmission and effectiveness. No particles in the air are recommended.

Recommended to replace once per year. Extreme usage, may result in shorter replacement time.

UVC is reflective, especially off of white surfaces. UV-C cannot penetrate is glass.

No effect on performance of disinfection. The towers and racks do have electronics and transformers that cannot exceed 40 degrees Celsius.

Rubber, cloth seats, plastic, insulation, etc.

It is comparable to exposure to sunlight. Long term exposure may produce fading or degradation of some materials.  Amounts of degradation are completely dependent on types and quality of materials and if they have UV-C protection built-in. 

There are thousands of these products in use worldwide primarily in the medical field. The towers and racks were just designed by Nemesis recently as a result of the lack of heavy-duty industrial type units on the market.

The Philips Radiator needs replacing once per year.  Extreme usage, may result in shorter replacement time.

Yes. They are inexpensive. Similar to the cost of a Fluorescent tube.

The radiator we are using is a Philips product that has been around for decades.  We recommends timings to kill at 255+ J/m2 (Joule per Meter squared) and the current Covid-19 strain is undergoing testing from various scientific organizations, at the moment it is believed to be killed in the 60-70 j/m2. See link for more information.

There are more than you can read about certified claims on the effects of UV-C. Nemesis products utilizes existing, proven UV-C radiators.  We’ve designed and built a very robust way to utilize them with overlapping photo metrics to increase the output of Nano-meters thus decreasing disinfection time.

** Information from Luxibel web site

  • UVC radiation has been proven to be effective against waterborne and airborne pathogenic micro-organisms including those responsible for cholera, hepatitis, polio, typhoid, giardia, cryptosporidium and many other bacterial, viral and parasitic diseases
  • UVC installations have low capital and operation cost
  • UVC technology is environmentally friendly
  • UVC installations are easy to operate and to maintain
  • UVC radiation has no harmful effect when overdosed on surfaces, water or air
  • UVC radiation works instantly and the effectiveness does not depend on the temperature
  • UVC disinfection is a physical process: no substances are added 
  • The UVC disinfection effect is directly related to the UV dose (which is the product of intensity and exposure time of the micro-organisms) so it’s effectiveness can be simply measured once the system design is validated
