What is UVC?
UV-C with a wavelength 200nm-280nm is the wavelength most effective disinfectant in the UV spectrum.
How does it work?
UV-C destroys the molecular structure of the DNA and RNA from microbial cells, causing the death of growth cells and / or regenerative cells, thus getting the effect of disinfection.
Some red or green LEDs will flash intermittently or steadily indicating the status of the device.
The lamp turns off immediately if it detects any movement.
An audible alarm will warn the user of the different states of the device.
The delay in the start will allow the operator to evacuate the area to disinfect
All appliances come with emergency signs to indicate areas to disinfect
- Motion sensor: the lamp automatically turns off if motion is detected
- Visual indicators: the red and green LEDs will illuminate continuously or flashing to provide a visual indication of the product status.
- Audio alarm: A built-in alarm will provide audible tones to alert users to different important events and claims that the product is working.
- Delayed start: Audio and visual indicators during delayed start allow the operator to leave the disinfection area before turning on the lamp.
- Emergency signaling: The products are incorporated with warning signs to indicate the area to be disinfected.
One of the key properties of UVC spectral bandwidth is that its radiant energy, when placed in the line of sight of a given surface, causes viruses, bacteria and mold spores to become inactive. Therefore, UVC is known as germicidal ultraviolet irradiation (GUVI).
No, in fact, GUVI has been studied since the late 1930th century with a focus on UVC since around 1935. In 1970, scientists tested the ability of UVC irradiation to effectively inactivate airborne microorganisms. In the 1990s, UVC irradiation was shown to reduce TB infection. Since the early XNUMXs, it has focused more on the efficacy and safety of UVC products as a way to inactivate viruses and bacteria, and is a proven and useful tool in this regard.
Multiple scientific reports show high rates of efficacy in reducing harmful microorganisms when used according to the manufacturer's instructions. For example, “the implementation of this contactless technology,” a sustained reduction in surface microbial contamination, a reduction in cross-contamination, and less spread of multi-drug resistant bacterial infections has been documented in several hospitals. In the Liscynesky et al. , in rooms of patients with confirmed C. difficile infection (CDI), 32 of 238 (13%) high contact surfaces were positive after disinfection with chlorine and only 1 of 238 (0,4%) was positive after UVC treatment at 254 nm emitted by 3 connected devices running for 45 minutes. [Evaluation of an ultraviolet C light emitting device (UVC) for the disinfection of high contact surfaces in critical areas of the Beatrice Casini et al Hospital, September 24, 2019].
When UVC radiation comes in contact with a microorganism, it causes a photochemical reaction as the radiation is absorbed. Damage occurs in the DNA of the microorganism. Mainly, the action of the photon absorption makes the microbe unable to replicate.
GOLDENSEA UV uses low pressure (Hg) mercury discharge lamp tubes. The tubes are made by Philips and Osram. These tubes emit UVC irradiation at 253,7 nm, which is close to the maximum microbicidal activity rated between 260 and 265 nm. This makes the tubes of the GOLDENSEA UV lamp utilize excellent options for this GUVI purpose.
No.a Unlike other disinfection methods, such as chlorination, UVC disinfection produces no residue. According to Philips (manufacturer of lamp tubes), no residual phenomena were found after the disinfection process.
Place your GOLDENSEA UV product to provide maximum exposure to the surfaces you want to disinfect. Use the correct GOLDENSEA UV product and set the appropriate time for the size of the area you want to disinfect. Remember to place the unit on a stable and secure surface. Remember that areas that are not directly in the line of sight of the GOLDENSEA UV unit cannot be disinfected. GOLDENSEA UV recommends using multiple units in one area if there are "shadow lines"
GOLDENSEA's UV products placed in direct line with the surface to be disinfected and appropriately configured for that area are designed to destroy up to 99.9% of micro-organisms in the path of the GUVI, however GOLDENSEA UV recommends that their products be used in conjunction with Other disinfection protocols for a full area approach and ensuring the highest levels of disinfection.
Few spaces have a clear line of sight throughout the area. Therefore GOLDENSEA UV recommends using multiple units located in different areas of the room to ensure further disinfection. Remember that GOLDENSEA UV recommends that its products be used in conjunction with other cleaning protocols to ensure higher levels of disinfection.
This depends on the product model (which defines the power of the GUVI being emitted) and then the power on time of the product. Consult the user manual or the product brochure where we list the time / area for disinfection of each product.
Product misuse and improper installation can make UVC products unsafe. Always follow the instructions set out in the user manual. UVC is very well researched and well understood. Compared to UV-A and UV-B, which are present in sunlight, UVC has little penetration into the deeper layers of the skin. The current daily safety limit for exposure of 253,7 over a period of 8h. it is 6mJ / cm2.
However, UVC exposure can cause temporary skin and eye irritation, and longer exposure can cause burns. When these products are used, living things SHOULD NOT be in the area to be disinfected. Objects can exhibit accelerated aging, similarly if exposed to direct sunlight.
The use of GOLDENSEA UV products has multiple safety circuits integrated into all of its products to reduce and avoid the risk of misuse resulting in injury.
Due to the protection circuits used in GOLDENSEA UV products, the user should never come into contact with a product when it irradiates. But, it is a plus for the user to wear protective glasses, nitrile gloves and well-fitting clothing that covers all exposed skin.
When replacing the lamp tubes, the product supply must always be physically disconnected from the wall and the user must wear protective glasses, nitrile gloves and tight clothing, covering all exposed skin.
No, almost 100% of UVC radiation is blocked by the glass used in the windows, cerium oxide, of which these glasses are made, it blocks the rays. The tubes in the lamp are made of quartz glass containing silicon dioxide that allows UVC radiation to pass through. That is why UVC passes through the glass tube and not through the Glass Window.
