Frequently asked questions about UV Sanitech

What are UV rays and what are the different types?

UV means “beyond violet” and refers to a range of electromagnetic waves with a shorter wavelength (higher frequency and energy) than the visible violet light. It can be produced by sun or by special UV lamps. UV is divided into three types with reducing wavelengths and increasing energy. They are UVA, UVB and UVC. For UV sterilization and disinfection, only UVC (200-280nm) has high enough energy to effectively kill microorganisms. UVC light, is highly effective at killing bacteria and viruses by destroying the molecular bonds that hold their DNA together. This conventional UV light is routinely used to decontaminate surgical equipment.

How does UVC Ray work

Ultraviolet germicidal irradiation (UVGI) works by breaking down certain chemical bonds and scrambling the structure of DNA, RNA, and proteins, disabling a microorganism’s ability to multiply. When a microorganism is unable to multiply, it is considered dead since it cannot reproduce within a host and is no longer infectious.

Is UVC technology a new technology for sanitization

UVC is not a new technology, having been discovered in 1879 it has been useful for cleaning infectious spaces especially surgical equipment’s. Thereafter more studies were done to determine the exact beneficial nature of UV for sanitization purposes. Since the 20th century, UVC has been used to disinfect things like water, air, fruits, vegetables, surgical utensils, tablet computers, toys, and a variety of surfaces. The most common use could be found in UV system for water purification.

What are the key parameters which determines the efficacy of UV rays in disinfection?

Since UV disinfection uses the energy of UVC to destroy biomolecules, its effectiveness depends on the total energy applied which is affected by the strength of the UV light source, duration of exposure time and the distance from the light source. For example, if you use a UV lamp held within 1 inch above a petri dish grown with E. coli, it will only take 1-2 min to show a complete sanitization killing them all.

Can UVC kill Coronavirus?

Studies have shown that UVC at 254 nm is effective against all foodborne pathogens, natural microbiota, viruses, and yeasts. The ionizing effects of UV radiation reaches out to the DNA of corona virus and other viruses and bacteria and kills them. UV sanitization kills 99.99% of viruses, including Corona virus, bacteria, and fungi in an extremely short amount of time. The effectiveness of Orient UV Sanitech has been optimized for germicidal efficacy at 4 minutes. It generates enough germicidal irradiation in 4 mins to kill bacteria’s and viruses including Corona virus.

Is UVC rays safe for humans?

UVC light has a very limited range and cannot penetrate through the outer dead-cell layer of human skin or the tear layer in the eye however direct exposure may have an adverse impact therefore, direct exposure on skin or eyes can be damaging and should be avoided. If UVC is used in a containment like in the Orient UV Sanitech, then it will be absolutely safe and not harmful at all.

There are many UV sterilisers in the market, how is Orient UV Sanitech different?

UVC is one of the most effective and safest way of killing bacteria and viruses. Orient UV Sanitech has been designed to consider three most important factor, energy applied which is affected by the length of exposure time and the distance from the light source. The timer ensures the exact duration of 4 minutes exposure so that the light source generates adequate energy to kill the bacteria and viruses.

Another important aspect is the design and placement of light source to give maximum exposure to surface’s and reduce the dark spots. Orient UV Sanitech uses two UV lamps of 11 Watts each placed diagonally providing sufficient UV germicidal irradiation with the surround reflectivity ensuring uniform spread of the UV irradiation from different angles thus increasing the efficacy of sanitization and reducing the dark spots. Orient UV Sanitech generates Ultraviolet light in the germicidal wavelength band covering 200nm - 280nm, specifically at 254nm – killing 99.99% of microorganism.

Most of the other available products have not been optimized for usage and are either poorly designed, leaving dark spots, having lesser surface coverage, or have less UV irradiation. In some of them timing of exposure is not fixed, all put together reduces the efficacy, thus seriously questioning their reliability.

There are many other safety features in Orient UV Sanitech. The Safety switch turns off the UV light when the door is open or is accidentally opened during operation. The rubber gasket on the lid prevents leakage of UV rays and the metallic painted body makes it robust. The metallic door prevents direct eye and skin contact with UV lights. Pre-set electronic timer with display ensures that the right dosage of UV light is delivered, preventing the consumer from making sub-optimal settings. The top opening of the box with a removable mesh ensures both ease of use and ease in cleaning.

What are the advantages of UV based disinfection against chemical-based sanitization?

It is convenient to use and no chemicals are needed, nor there is any chemical residual leftovers. Chemicals can have many side effects and can impair human health. Chemical based sanitizers can be corrosive and can cause wear and tear, and can have effects on the skin, and their efficacy is also limited. Most importantly not all objects can be sanitized with chemical sanitizers like fruits and vegetables. Sanitization with chemical sanitizers also takes lot of time.

Sun also emits UVC, so will exposure to sun can kill corona virus

UVC light from the sun is blocked by Earth’s atmosphere. When you go outside on a sunny day, the UV light that reaches you is UVA and some UVB. These types of UV light do not destroy viruses quickly. Only UVC has the ability of killing the bacteria’s and viruses.
