Why ultraviolet?

Ultraviolet light destroys the molecular bonds that hold the DNA of viruses and bacteria together. Hospitals have used UV light as a cleaning tool for years to decontaminate spaces, and now this technology is accessible to you.

Low carbon grant funding

The Low Carbon programme is supported by the European Regional Development Fund to provide a free business support programme in the UK. Its aim is to help businesses become more competitive and profitable, while protecting the environment and encouraging low carbon solutions.

Through organisations such as LoCASE, grant funding is available to SMEs (including those who have previously received help) right up until Spring 2023. This can be standard SMEs who are looking at ‘green’ projects, or Low Carbon Environmental Goods and Services (LCEGS) firms seeking grant funding for business development purposes.

Because UV Safe systems are proven to improve energy efficiency by reducing water and electricity consumption, their installation qualifies as a green initiative and you may be eligible for a grant to offset the cost.

    How it works

    There are several types of UV light. UV-A and UV-B occur naturally from the sun’s rays, but the technology in our units generates UV-C light. UVC is also known as ultraviolet germicidal irradiation (UVGI).

    UVC light is weak at the Earth’s surface as the ozone layer of the atmosphere blocks it, but UVGI devices can produce strong enough UVC to make them inhospitable environments for microorganisms such as bacteria, viruses, moulds and other pathogens. UVGI can be coupled with a catalytic filtration system to sanitise air and surfaces.

    The application of UVGI as disinfection has been an accepted practice since the mid-20th century. It has been used primarily in medical sanitation and sterile work facilities, but increasingly it is used to sterilise drinking and wastewater. In recent years UVGI has found renewed application in air and surface disinfection systems.

    Germicidal Irradiation by dual UV light kills microorganisms by disrupting their DNA and removing their reproductive capabilities.

    UV reacts with a catalyst to form highly reactive but short-lived oxidising Hydroxyl Radicals (OH) which break down Volatile Organic Compounds (VOCs).

    Interaction of the dual waveband UV with the catalyst both creates and breaks down oxygen molecules, transforming oxygen into highly reactive states of ozone and superoxide ions which leave the unit as “plasma quatro”.

    The negatively charged superoxide ions charge airborne contaminates, causing them to cluster together and fall from the air as they become too heavy, aiding all other processes. This can remove airborne particulates down to 0.0001 micron – better than any HEPA filter.

    Optional – targeted ozone produced via the specialist lamp gets to the hardest to reach areas, breaking down contamination in the air and on exposed surfaces. Ozone damages the cell wall of microorganisms, stopping reproduction and destroying the cell.

    These units have been shown to kill a wide range of microbes that are more difficult to eradicate than viruses, including bacterial species that produce endospores (Clostridium difficile, Geobacillus stearothermophilus), Gram-positive bacteria (Staphylococcus aureus, MRSA, S. epidermidis, Listeria monocytogenes and L. innocua), Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa), and moulds (Aspergillus fumigatus) in both the air and/or on surfaces.

    Decontaminating with UV-C light (UVGI)

    At UV Safe we have used UV-C light to treat a range of products and surfaces to validate them against pathogen inactivation. Its applications are diverse. For example, we have been exploring UV-C light for tool disinfection between shift engineers for the aerospace industry. And although UV light technologies have been around for a long time, only in the past few years has the food and drink industry grasped its potential.

    UV-C light can be used on a variety of food products to help:

    • improve quality.
    • extend shelf-life, or
    • reduce water and chemical usage.
    • reduce a product’s microbial level.
