UV Technology


WHAT IS ULTRAVIOLET (UV) LIGHT?

Ultraviolet light is grouped into three categories based on the lights wavelength. There's ultraviolet A, ultraviolet B and ultraviolet C. The sun produces all three types of UV radiation, but we only experience A and B on Earth's surface. UVC does not penetrate the clouds, so it doesn't hit us here on Earth.


HOW DOES UV WORK?

Ultraviolet light is grouped into three categories based on the lights wavelength. There's ultraviolet A, ultraviolet B and ultraviolet C.

HOW DOES UV KILL GERMS & VIRUSES?

  • UV light damages the DNA and RNA of microorganisms and prevent them from infecng.
  • UV damages their DNA or RNA as is oen the case in viruses which stops them from replicang. Over me, the germs’ cells die and break down.

MORE THAN 100 YEARS OLD PROVEN TECHNOLOGY

UVC has been known for more than 100 years now to be really good at killing microbes, bacteria and viruses. Both ultraviolet light is part of the electromagnec spectrum, which includes gamma rays, X rays, infrared light, microwaves& visible light radio waves.

ADVANTAGES OF UV SANITIZATION


Safe on Electronics & other Items:
  • UV light is non-flammable and can be used on surface with any temperature and on any electrical items.
  • UV-C is a dry sanizaon hence it can be used on any type of surfaces like fabric, paper, electrical and electronic item like computer, power socket, mobile TV etc.

Economical
  • UV disinfection is the most affordable sanitization method. It has low inial capital cost as well as reduced operating expenses when compared to similar technologies such as liquid sanitation.

Higher & Faster Return on Investment (ROI)
  • To maintain sanized place through liquid sanizer, you have to incur higher yearly cost considering liquid sanizer consumpon, sweeper cost, wiping cloth and other cleaning accessories. At the same me UV sanizaon cost you 10% of the amount as only electricity power consumpon cost is involved in UV sanizaon

Cost Advantages of UV Disinfection
  • A one-me investment in UV light disinfecon technology can save you me and money for years and since the unit can operate autonomously when installed you don’t have the associated labor cost and chemical cost, which is very high.
  • Annual lamp replacement and electrical consumpon comprise the operang costs of UV disinfecon.
  • UV eliminates or reduces the immediate safety threat of chlorine gas without creang new long term costs associated with chemicals, transportaon & delivery.
  • Costs for leak response, administraon, risk management and emergency planning and operator training are minimized and/or eliminated with UV

DISADVANTAGES OF LIQUID STERILIZATION


Harmful & Unsafe
  • Harsh toxic chemicals are used in liquid sanizaon products.
  • It is harmful for human body and unsafe to use on any eatable or drinkable items.
  • It may cause food poisoning and voming.

Causes Fungus
  • Liquid disinfection method causes fungus and it leaves a moist environment where fungi can thrive

Inflammable & Unsafe
  • Liquid sanizer catches fire if its sprayed on hot surface or vehicle engine and leads to short circuit if sprayed on electrical item.

Damages & Leaves Stains
  • Chemicals end up being very corrosive on the surfaces.
  • Liquid sanizaon cannot be used on fabric, paper, electrical and electronic items as it damages the electronics and also leaves stains on fabric, paper etc.

Recurring Cost & Expensive
  • Liquid Sanizaon gives recurring cost throughout the year and is expensive due to frequent chemical usage.

Incomplete Sanitation
  • Liquid sanizaon is a manual process and has possibilies of human error and is controlled by the labour’s aendance and to their whims.
  • As it is a manual process, it doesn’t guarantee the complete area to be sanized as there are chances of some areas being le out from sanizaon by the labour.
