UV-C Technology explained
UV-C radiation
Ultraviolet-C (UV-C) radiation is the type of ultraviolet germicidal irradiation (UVGI) with wavelengths around 200-280 nm, demonstrating high decontamination efficiency among UVGIs. The powerful germicidal properties of UV-C have been recognized for over a century.Â
Disinfection with UV-C
​UV-C has become a crucial method for inactivating a wide range of microorganisms, including bacteria, viruses, and fungi, making it an essential tool in combating airborne pathogens. It is widely used in food processing and water treatment due to its efficiency, low cost, and, most notably, zero chemical residue. The potential of UV-C has also been explored in healthcare, such as to reduce or inactivate different airborne viruses, such as influenza, surface bacteria, and multi-drug-resistance bacteria in hospital rooms. Recently, the use of UV-C as a disinfectant has escalated, mainly to decontaminate surfaces and medical instruments in healthcare facilities.
How does UV-C disinfection work?
When UV-C radiation is exposed to microorganisms, the rays are absorbed by bases of the organisms’ nucleic acids (DNA and RNA), and the photodimerization process occurs. This process results in the formation of cyclobutane pyrimidine dimers in the DNA and RNA strands, inhibiting cell replication ability, and ultimately, cell death occurs.
UV-C LAMPS
The most common method of producing UV-C is with the mercury vapor discharge lamp, where an average of 14-30% of the energy is converted to UV-C. Good quality lamps are made of a special glass that blocks ozone-forming radiation but still contain mercury.
BENEFITS OF UV-C TECHNOLOGY
ECO FRIENDLY SOLUTION
By harnessing UV-C LED radiation, we reduce dependency on harmful chemicals and conserve water, offering a mercury-free solution that minimizes environmental impact. As UV-C is not naturally present on earth, organisms have not developed resistance. All organisms, even methicillin-resistant ones are susceptible to UV-C LED radiation.
COST EFFICIENCY
UV-C LED radiation offers a cost-effective alternative to traditional UV-C disinfection methods. With a long lifespan and minimal electricity consumption, each radiation dose consumes a mere 5W of electricity, reducing operational costs and energy waste
VALIDATED & AUTOMATED
Our high-level UV-C LED disinfection is validated and automated, offering peace of mind by preventing cross-contamination and ensuring consistent, reproducible object disinfection with each use.
SAFETY FIRST
Safety is our priority at Zaparay. Our devices feature no fragile glass tubes,
and our UV-C LEDs are equipped with a triple safety circuit.
TIME EFFICIENCY
Efficiency meets convenience with UV-C LED radiation. Easy to use and single button operated, our disinfection devices guarantee high level disinfection in less than 5 minutes. Since instruments remain dry, there's no need for additional handling, saving even more time and resources.
HEAT FREE ASSURANCE
UV-C LEDs operate at room temperature, ensuring efficient disinfection without producing heat or the need for warm-up times while safeguarding instruments and materials from damage.
HARMLESS FOR ALL MATERIALS
Unlike aggressive chemical disinfection agents, UV-C LED radiation is less harmful to materials. It produces no corrosive ozone gas and enables the disinfection of a wide range of materials, including plastics and electronic devices, all while operating silently.
IMPROVED & DECENTRALIZED
Manual chemical disinfection methods often fall short in achieving adequate pathogen reduction. With UV-C LED radiation, we overcome this challenge mitigating the risk of healthcare-associated infections (HAIs). The compact nature of our devices enable a decentralized disinfection procedure.
