Nowadays, Water Purifier is a common commodity in our homes. Maintenance and servicing of Water purifiers are very much essential so that they can continue to produce safe water to drink. It is crucial to have a regular Water Purifier service and that may include UVC tube change after a certain volume of water purification.

It is necessary to change the UVC tube at regular intervals during your water purifier service (may not be required with every service). Ultraviolet light is considered one of the most effective ways to get rid of harmful pathogens/ bacteria. Regular water purifier service with timely UVC light tube change is highly effective in keeping the water pure.

Know more about trusted UVC Technology in Water Purifiers 

As per a report published by the Global Lighting Association, “UVC treatment is an established technology for disinfection and has been applied extensively since 1910 when it was discovered that it can neutralize microorganisms such as bacteria, moulds and yeasts, as well as – and very importantly – viruses…”.

The same report also says “UVC is commonly associated with radiation within the 100-280 nm wavelength range. Below a wavelength of 200 nm (commonly referred to as vacuum UV), UVC is strongly absorbed by atmospheric oxygen and ozone. Lamps and/or systems designed to provide UVC radiation above 200 nm are utilized for surface, air, and water disinfection.”

The Blue wavelength in the visible light spectrum is the most imminent one to the UV light on the light spectrum and has the highest energy of the Visible Light spectrum. However, it doesn’t carry the disinfection characteristic of UVC light.

UV light contains UVC (100 nm to 280 nm), UVB (280 nm to 315 nm), and UVA (315 nm to 400 nm). The atmosphere blocks natural UVC and most UVB rays, with UV-A accounting for 95% of rays reaching the earth’s surface.

UVC radiation involves a whole lot of applications, and in many ways, it influences our lives. One of the most critical applications is in the Water Purifier. Water is the absolute need of a human body, without which it is near impossible for humans to work effectively. Children, in particular, need to make sure they re-hydrate, as water is the primary way they regulate their body temperature.

UVC Tubes, best known for water purification in a large number of household water purifier services, has another important aspect of air purification in HVAC or Air Ducts

As movie halls or multiplexes across the globe begin to reopen, owners are now focussing actively to address issues around health and safety. As part of post-pandemic precautionary measures, one needs to ensure premises are clean and provide germ-free air to staff as well as the viewers.

This also leads us to question if the AC Duct or the HVAC (Heating, ventilation, and air conditioning)  systems used in these public premises are running safely, emitting bacteria/ virus-free air? The answer to this is the use of UVC Tubes.

How UVC Tubes Disinfect the Air Circulating through HVAC system or AC Ducts?

Movies have always been an integral part of our society and are one of the prime sources of entertainment across not only India but also the globe. Multiplexes have multiplied in double-digit numbers over the past decade and are anticipated to develop even more.

As more people started flocking to theatres, their safety and mental satisfaction has become of prime importance for the theatre and multiplex owners. A clean, safe and healthy environment is essential for a better movie-watching experience more than ever today.

Today modern theatres or multiplexes are equipped with state-of-the-art sound and video facilities, luxury recliners and other comfort-building factors, like top-class AC Duct or HVAC systems that attract audiences in large numbers.

These AC Ducts or HVAC systems keep the air cool and also keep humidity in check. However, microbes may start formulating in humid places. While these HVAC systems keep the environment clean, over a period of time they may become a breeding ground for microbial pollutants.

If the pollutants start to mutate, they may with air passing through the vents, create harmful virus-filled air that could lead to contamination. To eradicate and combat these pollutants, UVC Tubes is recommended.

UVC tubes can be installed in the ventilation ducts of these HVAC systems ensuring clean breathable air is released. When the air passes through the AC ducts or HVAC systems, the UVC suppresses the formation of the bacteria by breaking the building block (DNA) and stopping it from multiplying.

UVC Tubes – Is the Use Economical?

UVC Tubes used in air purification is more economical and efficient than other air filtration and cleaning methods and is recommended for public premises such as theatres or multiplexes.

UVC Tubes, which is widely used in a large number of household water purifier services, has another important aspect of air purification in HVAC or Air Ducts.

Today UVC disinfection equipment can employ single or multiple UVC tubes depending on the area of function. The high reliability of UVC disinfection equipment with UVC tubes is therefore expected to drive the demand from various applications such as HVAC or AC Duct system that help ensure clean purified air.

The performance of a UVC germicidal irradiance, therefore, depends on correct design calculations with proper derating and life estimations followed by thorough evaluation through testing and verification by professionals.

UVC tubes used in HVAC systems across offices is known to provide various benefits and offer sustainable, cost-effective solutions.

HVAC systems are common in almost all corporate offices 

A healthy environment is essential for employees at an office. Keeping in mind the new health & safety norms of the local authorities and those set out by WHO, today’s employers need to ensure employees have a safe, breathable, virus-free office to step into each day. A healthy workforce is a far more productive workforce than one exposed to harsh, filthy air penetrated through HVAC systems, which is why regular HVAC air-stream disinfection is required.

Studies have demonstrated that an office with a favorable and healthy environment improves production by many folds. This not only boosts the productivity of the employees but also helps with keeping top quality personnel and further helps strengthen the interpersonal relationship.

Air conditioners or HVAC systems in the office provide a suitable and comfortable environment to work in.

Just as our AC’s at home, HVAC systems used at offices, halls, theatres, gyms, need routine maintenance and cleaning. Bacteria and viruses could accumulate over a period of time if proper care is not taken. These bacteria and viruses once heaped up inside the HVAC systems can further enter the room through the ducts and may create unhealthy unbreathable air.

Since not using the air conditioners or HVAC systems is not an option, it is advisable to kill the bacteria or viruses to avoid contamination, the spreading of illnesses and diseases and to emit good quality air. The process of HVAC air-stream disinfection is therefore advisable and should be carried out by professionals.

The Air Movement And Control Association (AMCA) states this process is executed in the following manner:

‘UVC tubes fixtures installed in air-handling-unit (AHU) plenums, air-distribution systems, or HVAC ductwork inactivates microorganisms “on the fly.” Simplified, the germicidal dose is determined by the UVC intensity, exposure time, and target pathogen’s susceptibility to UVC. In addition to the amount of germicidal energy absorbed by a pathogen over a specific amount of time, a variety of other factors are taken into consideration when UVC is applied for HVAC air-stream disinfection. These site-specific considerations will be explored in the next section.’

As stated in the 2020 edition of AMCA in motion magazine.

Ultraviolet (UVC) purification is the de-facto way of eradicating these harmful bacteria, viruses, and pathogens. OSRAM PURITEC® HNS® UVC germicidal tubes emit light at 254 nm, which is very close to the maximum effectiveness, and are highly recommended as they are also ozone-free.

HVAC or AC Duct systems are used in big commercial establishments across India. To ensure the quality of air generated is germ-free, usage of OSRAM HSN® UVC tube is recommended, especially in larger setups like hypermarkets or supermarkets.

Can supermarkets make the HVAC or AC Duct free from turning into a breeding ground for germs, bacteria and viruses?

Before the pandemic, millions across India and the globe would carry out daily purchases at supermarkets. Supermarkets had evolved to more than just places to purchase groceries and where one could experience new products, taste samples, drink a coffee or eat a sandwich as they pushed their grocery carts across various aisles and their children played in makeshift play areas with others.

Socializing and moving about freely as we carried out routine tasks were made pleasurable. However, today’s shopper faces a different scenario while shopping for basic needs and essentials.

Questions that loom include-

Is this safe?

Am I compromising on my health or my family’s health by being here? Am I risking my health?

Solutions to curb the spreading of germs and viruses and create clean air in supermarkets

As the world steps into the new normal, health and safety rules become more stringent and we look to new ways to adapt and provide consumers with a safe shopping experience. Larger supermarkets, hypermarkets, malls need to step up measures to help customers shop at ease and safely.

Besides following the health & safety protocol stated by local authorities and the WHO, they need to find solutions that address their customers’ concerns and ensure their supermarket staff are working in a safe and healthy environment.

An effective way to tackle and curb the spreading of germs or virus and provide healthier air for all is with the help of UVC technology which proves to be cost-effective, reliable and is a safe technology that keeps HVAC or AC Duct systems functioning for long.

Supermarkets, hospitals, factories across the world majorly rely on HVAC or AC Duct systems. These premises need to be disinfected regularly as they are often crowded, have large groups of people working in shifts or visiting across the day. They are also often filled with fumes, heat and excessive humidity.

As a result, the HVAC or AC Duct systems need to be maintained properly to prevent the accumulation of viruses and bacteria. If left untreated, they attach to the AC ducts and are released via the vents.

The Lincoln Tech blog states contamination of this level on HVAC or AC Duct systems should not be ignored. This often contributes to building-related diseases, like viral or bacterial infections, allergic rhinitis, asthma and hypersensitivity pneumonitis….’.

They further report, ‘Proper air filtration is the first line of defence against the circulation of microbes within your HVAC or AC Duct system. With the right conditions and proper installation, UV lights can effectively kill viruses, mold, and bacteria.’

The simple UVC Lamps installed in the HVAC systems or the AC ventilation ducts help purify the air.

By destroying the DNA and RNA of the microorganisms such as bacteria, molds, yeasts, etc., these UVC Lamps allow clean, pure air to flow across. They further help prevent viruses and bacteria from multiplying and spreading.
