UV PURIFIER - HELPS MITIGATE VIRUSES IN THE BUS INTERIOR

Scientific data demonstrates that the UV purifier has an inactivation rate of approximately 95% of the SARS-CoV-2 virus its variants, bacteria, mold and other pathogens on average in one air cycle. The UV purifier begins inactivating the viruses in the air in the passenger compartment of a bus as soon as you turn it on. We strongly recommend running the device continuously for best results.

Find out how it works:

Purified air thus flows continuously during the entire journey and circulates in the passenger compartment, ensuring that the virus concentration in the bus is mitigated.

Exposure time and intensity, blow-through speed and geometry are carefully coordinated to ensure that the air stream emerging from the box is virtually virus-free (>95%).

UV-C RADIATION INACTIVATES THE SARS-CoV-2 VIRUS

Irradiation with UV-C light (254nm) is a scientifically tested method of disinfection by the inactivating microorganisms and various viruses, including SARS-CoV-2. With adequate exposure time and intensity, the DNA of the virus is cracked and destroyed, so that it can no longer reproduce itself. When the lights interact with viruses and bacteria, they damage the structure of the virus/bacteria and effectively neutralize them.

UV Purifier uses this best practise technology in buses, transit or city buses.

Based on scientific evidence, it reduces the concentration of viruses in the air just as effectively as a fresh air supply.

  • Low noise level
  • No influence on the thermal well-being

SUITABLE FOR EVERY BUS - COMFORT FOR THE OPERATOR

The UV purifier can be used in all types of buses worldwide. The device is suitable as a retrofit solution as well as for installation in a new vehicle.

UV purifier Vent is installed directly in the passenger compartment and offers special advantages for the operator:

  • Plug and Play - immediately ready for operation
  • Easy assembly/mounting
  • Modular and completely autonomous operation
  • Continuous operation while driving
  • No distraction on the efficiency of an existing air conditioning system
  • Long-lasting almost maintenance-free operation: lamp replacement only after approx. 12,000 operating hours
As UV purifer AC a UV-C lamp is integrated into the existing heating/air conditioning system of the vehicle. A retrofit solution is also possible here.

FIND ANSWERS TO YOUR QUESTIONS

Scientific data demonstrates that the UV purifier has an inactivation rate of approximately 95% of the SARS-CoV-2 virus its variants, bacteria, mold and other pathogens on average in one air cycle. The UV purifier begins inactivating the viruses in the air in the passenger compartment of a bus as soon as you turn it on. We strongly recommend running the device continuously for best results.

No, the device does not require any maintenance, there are no maintenance parts like filters or similar. However, in particularly "dusty" conditions, it is recommended to remove dust from the lamp, as otherwise the effectiveness of the radiation may be impaired.

With a running time of 12,000 hours the installed UV-C lamps are very durable and need to be replaced only very rarely. The UV purifier has a blink code fault diagnosis output that can be used to detect lamp failure or malfunction at an early stage. Due to the protective and stable aluminum housing, the devices are optimally suited for long-term use in public road traffic.

Yes, the operator can do this himself at any time. Of course, the device must be without power supply in any case, and all other safety regulations according to the operating instructions must be observed.

Basically yes. The Association of German Transport Companies recommends a fresh air supply in accordance with VDV 236, which applies to all buses equipped with an air conditioning system with a fresh air flap that allows a fresh air supply of 100%.

However, there are conditions in which this type of fresh air supply is insufficient, so that further measures against viruses are strongly recommended to achieve the fresh air effect.

Such conditions are:

  1. From approx. 23° C outside temperature, when the proportion of circulating air from the air conditioning system increases significantly at the expense of fresh air. The proportion of fresh air is then no longer sufficient to reduce the virus load in the bus. The same applies to temperatures below 15°C.

  2. There are still many vehicles worldwide that are equipped with air conditioning, but without a fresh air flap. Or else, the existing fresh air flap only allows an approx. 20-30% fresh air supply.

  3. In many countries there is still a large number of buses that are not air-conditioned at all and do not have fresh air ventilation devices.

>>> Conclusion: We do not always get as much fresh air into the bus as we would need!

As a UV purifier Vent, the unit can be used at any time, regardless of the presence of an air conditioning system. This is particularly important in order to be able to react very quickly in the current situation, so that the existing bus vehicles in the field can be easily upgraded with UV protection.

The plug-and-play retrofit kit of the UV purifier Vent can be installed quickly and flexibly and is ready for operation in no time.

It is very important to bring the virus concentration in the bus interior to the level of the VDV Fresh Air Recommendation as quickly as possible. This can only be achieved if very fast and very effective action can be taken against the viruses:

  1. Valeo uses UV-C technology, which effictiveness has been scientifically demonstrated. When the lights interact with viruses and bacteria, they damage the structure of the virus/bacteria, effectively neutralizing it.
  2. Valeo uses UV-C lamps with an optical performance of 26W and an electrical power of 70W
  3. Irradiation time and intensity, blow-through speed and geometry are optimally matched to each other, resulting in the design of the UV purifier.
Valeo has succeeded in increasing the radiation dose, which is harmful to viruses, while at the same time keeping it in the box so that there is no danger to passengers at any time, when used as directed.

Yes, the effectiveness of UV purifier has been confirmed by tests with the SARS-CoV-2 virus. Scientific tests of the effectiveness of the lamps used was provided by the Institute for Medical Virology at the University Hospital Frankfurt. The risk of infection with SARS-CoV-2 is therefore reliably and efficiently minimized by disinfecting the interior air with UV-C radiation.

No, the UV purifier does not produce ozone for two reasons:

  1. Valeo uses high-quality UV-C lamps with a wavelength of 254 nm. UV-C radiation at this wavelength does not produce ozone.
  2. Valeo uses extra-thick doped quartz glass, which does not produce ozone due to its special manufacturing process.
More detailed explanation: The Ultraviolet spectrum contains four separate wavelengths—UV-A, B, C and Vacuum UV—each operates at different energy levels and only one is capable of producing ozone (Vacuum UV). In a nut shell, UV irradiation in the 100-200nm range is capable of producing ozone. UV-C, conversely, reaches its optimal germicidal strength near 253.7nm. Because ozone may only be produced below 200nm, at 253.7nm (rounded to 254nm), the germicidal wavelength does not generate ozone.

In addition to the stronger 254nm wavelength that does not produce ozone, UV-C lamps offer another layer of ozone protection.

Most germicidal lamps, including those from UV Resources, are produced with doped quartz glass, which blocks the transmission of the 185nm ozone-producing wavelength. The doped quartz glass allows the 253.7nm radiation to pass through, but it blocks the 185nm wavelength from escaping. Therefore, germicidal lamps with doped glass does not produce ozone.

UV-C air disinfection with Valeo UV purifier in buses can be used as a supporting measure and as part of efforts to stop the spread of SARS-CoV-2, other viruses and bacteria. The option of vaccinations or general hygiene considerations, such as social distancing, wearing face coverings, washing hands and ventilating the bus regularly must also be observed.
