Disinfection of room air with UV (UVGI) light

Chemical-free disinfection for hospitals and medical practices

In hospitals and medical practices doctors and nursing staff work amidst constant exposure to a large number of pathogens. Likewise, in dental practices the aerosols of patients create a drect exposure risk for dentists and dental hygienists. Although disinfecting surfaces and objects is common, disinfecting the air is not. However, aerosols pose a considerable infection risk. The consequence: staff and patients may not be safe.

If too many employees are absent due to illness, this places even more stress on the still active staff further endangering their health. In addition, the situation causes bottlenecks that delay patient care. Furthermore, patients with pre-existing conditions are particularly at risk from germs in the indoor air.

A portion of the air recirculates again and again via the ventilation system. As a result, pathogens spread very quickly throughout the building. Systems with air filters also have a residual risk. HEPA filters of classes H13 and H14 can filter viruses. However, the major disadvantage of filters is that the pathogens are not killed or, in the case of viruses, inactivated. The filters quickly become heavily loaded with active pathogens. Leakage or improper handling of the filters during maintenance and replacement can release these active pathogens.

The solution: Room air disinfection with UV (UVGI) light

The solution is called Soluva® Air D. We retrofit these UV disinfection modules that into every kind of ventilation system. Depending on the design, Soluva® Air D disinfects up to 25,000 cubic meters of air per hour. We would be happy to advise you in detail, carry out the UVC dose calculations and prepare a quotation for you. These complimentary services do not commit you to anything. Simply contact us! We look forward to your inquiry.

Heraeus Noblelight: Expertise in light for over 118 years

As pioneers in UV disinfection, we offer you the most expertise, proven high-performance products and comprehensive individual advice. Over 100 years ago our company developed the first UV high-pressure lamp. Therefore, we are not only market leaders, but also pioneers in ultraviolet disinfection, also called ultraviolet germicidal irradiation (UVGI). We constantly modify our products for new applications and adapt them again and again to the specific needs of our customers.

UV disinfection has been working reliably for many years in:

  • hospitals, medical practices, laboratories and clean rooms
  • airports, offices and theaters
  • water treatment and in the food industry

Effect of UV light on pathogens

UV light disinfects surfaces, air and water. More precisely, it is the particularly short-wave and high-energy light of the UVC spectrum. When disinfecting with UVC light, the DNA of viruses, bacteria and molds absorb the ultraviolet rays which destroy their structure. The UV light kills 99.9999% of the pathogens by inactivating the viruses, even multi-resistant germs. The application is simple, effective and efficient. Microorganisms cannot build up resistance to UV disinfection.

UV disinfection of surfaces and objects

Soluva® Zone H: Product in development
Soluva® Zone H: Produkt in Entwicklung

In addition to air disinfection, the fast and safe disinfection of surfaces and objects is also important in hospitals and medical practices. What was tedious and often cumbersome using wet disinfection is now quick and easy using the mobile, battery-operated Soluva® Zone H disinfection device. After just a short introduction you can integrate the use of the Soluva® Zone H into your healthcare environmental cleaning procedure.

Disinfect restrooms, handrails, handles, elevator buttons, keyboards, fittings, treatment beds - in short: everything that many people touch - with ultraviolet light. Simply by moving the disinfection unit over the surfaces and objects at a certain distance and speed. Experience has shown that users learn very quickly which speed and distance are optimal using test strips. The Soluva® Zone H is ergonomically designed and as easy to use as a hair dryer.

The fire department of Erlensee-Langendiebach successfully tested the Soluva® Zone H to disinfect such things as flashlights, emergency radios and thermal imaging cameras as well as the interiors of fire engines, tables with laptops and emergency radios.

  • Electrical power: 39 Watt
  • UVC power: 14 Watt
  • Charger voltage: 230 V / 50 Hz
  • Weight: 2 kg, plus battery
  • Color: black
  • Maintenance: after 1000 operating hours
  • Size: 550 × 180 × 120 mm

*All data refer to the current development status.

University study proves it: UV light also inactivates Covid 19 pathogens

In cooperation with the Molecular Virology Research Section of the University Hospital of Tübingen, we tested two Soluva® products. We wanted to know how our UV disinfection devices work against the Covid-19 pathogen. The results are clear: Soluva inactivates 99.99% of the viruses within a few seconds.

This is the scientific proof that our Soluva® products disinfect surfaces quickly and reliably. We will be happy to send you further information on the study upon request.

Powerful and long-lasting UV lamps

We offer particularly high-performance UV lamps. Soluva® products disinfect much faster than other products. In addition, they work with a large scattering angle which makes the application faster and safer, because you can reach even difficult angles.

Due to a special coating on the inside, our UV lamps are particularly long-lasting. Because of the longer operating hours per lamp you save further on maintenance costs and valuable working time.

UV disinfection: additional applications in medical facilities

In addition to surfaces and objects in waiting areas and treatment rooms, you can extend occupant safety by using UV disinfection devices in the laboratory, offices, meeting rooms and the cafeteria. For this we offer solutions for every need: from space-saving table-top units, slim floor-standing units, quickly mounted wall and ceiling units to self-propelled robots.

Disinfection with UV light: now and for the future

SARS-CoV-2 has shown the world how vulnerable humans are. And how important it is to protect especially the weak, the sick and the staff in hospitals and medical practices. Covid-19 will not be the last disease to spread worldwide through new, unknown pathogens. Due to ongoing globalization, further pandemics are unfortunately to be expected even after the corona pandemic.

How does UV disinfection of air, surfaces and objects work?

Ultraviolet light is an electromagnetic radiation in the range of optical frequencies. The wavelengths are so short that the ultraviolet radiation is invisible to the human eye. The wavelengths are divided into UV-A, UV-B and UV-C. We use UV-C light with a frequency range between 280 and 100 nanometers for disinfection.

UV-C light is very short-wave and very energy-rich. UV-C light inactivates bacteria, viruses and fungi. Air, surfaces and objects can be sterilized by irradiating them with UV-C light. UV light is therefore a chemical-free, environmentally friendly and efficient alternative to liquid disinfectants.

The same applies to Soluva® Zone H for UV disinfection: Protect your skin and eyes from ultraviolet radiation. That's why the Soluva® Zone H comes with gloves and a face visor. In addition, please wear long sleeves and a cap to protect your scalp.

All other UV disinfection systems such as floor standing units, wall mounted units or tabletop units shield occupants from the UV rays.
