Frequently Asked Questions
It is scientifically proven that UVGI kills all bacteria, spores, viruses, protozoans, molds and yeasts. The level of UV irradiance in our cabinets will kill 99.99% of Poliovirus 1, SARS, H-CoV 229E, H-CoVOC43, H-CoV 229E, Influenza A (H1N1), Covid 19 in under one minute of exposure to UVC light (*ref.: M. Buonanno, D. Welch, I. Shuryak, D.J. Brenner; DOI: 10.21203/ rs.3.rs -25728/v1), (*ref.: Tree et al. 2005), (*ref.: CDC, 2020). By increasing the exposure, higher log reduction is achieved.
Uvisan cabinets are designed in a way that no UVC radiation can escape. This is reinforced with IEC 62471 Photo-biological Safety certificate placing Uvisan in the Exempt group - the highest possible safety standard. Additionally, all devices are equipped with a door safety switch preventing accidental light exposure (in the event that the doors are opened during sanitization cycle).
Uvisan Cabinets are completely safe for all users, domestic and corporate. All the devices have CE, RoHS and IEC 62471 and are certified for Electromagnetic Compatibility in line with Low Voltage Directive. Additionally, our manufacturing processes are in line with ISO 9001 and ISO 14001.

Uvisan has third party lab certificate confirming antibacterial efficacy and are using medical grade UVGI lamps, which are proven to kill the bacteria, spores, viruses, protozoans, molds and yeasts.
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (ultraviolet C or UVC) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA. This leaves them unable to perform vital cellular functions. UVGI is used in a variety of applications, such as food, air, and water purification.
NIOSH (National Institute for Occupational Safety and Health) defines a safe exposure limit for ozone at 0.1ppm. Uvisan lamps total combined production is very small - 0.07 particles per million (measured inside of the cabinet at the maximum concentration). Any Ozone that is produced is filtered out immediately and prevented from ever leaving the bulbs.
No living creatures are allowed inside of our cabinets. Other than that, almost every commonly used item which needs a surface disinfection can be cleaned. Metals, various plastics, cardboard, rubber surfaces can be safely sanitized in our devices.
Yes, it does (CE, RoHS, IEC 62471, Electromagnetic Compatibility/Low Voltage Directive, ISO 9001, ISO 14001, Sterilization Efficacy Evaluation certificate)
Yes, we have a standard two-year guarantee, and we provide customer support.
We have done excessive stress testing with various headsets and other popular electronic devices (mobile phones, tablets etc.) simulating 1.5 year of standard usage. We observed no impact of the UVC radiation neither on the appearance nor on functionality.
All the electric and electronic devices are protected by circuit breaker and RCD module. Also, during normal operation, the temperature inside the cabinet is in the region between 20 and 30 degrees Celsius. Additionally, the cabinet is made of non-combustible materials (mostly steel).
10 kg per shelf is the maximum we recommend.
Small: W600 D350mm H200mm
Medium: W600mm D550mm H220mm
Large: W750 W600 H220mm
Height is adjustable - each shelf can move up and down by 4cm. Due to modular construction there is also the possibility of shelf removal. The standard vertical clearance between the shelves is 20cm, maximum clearance (with two shelves adjacent) is 28cm.
It is specific to the lamp - an electric discharge produces UV radiation in a very narrow band (peak exactly at 254nm). There are also small "sidebands" produced in a visible range (over 400nm) - this is the pale blue color characteristic to all UVGI lamps.
Lamps offer almost constant UV output over their complete lifetime. For maximum security of disinfection and high system efficacy - always 254nm. Lifespan of our lamps is 9000 hours. With a standard working cycle (4 cycles an hour, 8 hours a day, 5 days a week) - annually this accounts to 693 hours.
The cabinets are designed to work in ambient room temperatures (temperature range 18 - 30 degrees Celsius). Cabinets are not designed to work in wet or cold conditions.
No, it will switch off automatically after the cycle is finished.
We recommend dusting the cabinets with soft cloth as a standard daily practice. Outside of the cabinet should be wiped with 70% alcohol wipes.
We would suggest gloves are worn as an extra precaution to prevent contamination post disinfection cycle.
