Bactericidal recirculators in Lviv

Bactericidal recirculators are important for ensuring biological safety in indoor environments. This article presents the technical aspects of selecting, operating, and evaluating the effectiveness of these devices in urban conditions.

What is a bactericidal recirculator and where it is used in Lviv

A recirculator is a device for disinfecting air using ultraviolet radiation in the C range (wavelength 253.7 nm). The design consists of a closed housing with ozone-free lamps and fans installed inside. Air is forcibly drawn into the unit, passes through an intense UV field, and returns to the room purified from 99.9% of viruses, bacteria, and fungal spores. Along with recirculators, classic quartz sterilizers remain relevant for fast and deep surface sterilization in unoccupied spaces.

Differences between recirculators and open-type lamps

The key difference lies in safety for humans. The closed housing of a recirculator completely blocks direct UV radiation, allowing the device to operate in the presence of people throughout the day. When total disinfection of premises is required, including hard-to-reach areas, ozone bactericidal lamps can be used. Gaseous ozone effectively destroys pathogens in “shadow” zones where direct light does not reach, ensuring sterility even in complex structures. However, it is important to remember: their use is strictly allowed only in the absence of people, and after treatment the room must be ventilated.

Main areas of application: homes, offices, medical facilities

In residential buildings, recirculators minimize the risk of cross-infection among family members during seasonal outbreaks. In office centers, installing such devices helps maintain staff productivity. In medical institutions, in addition to air purification systems, specialized devices such as tubus quartz devices are also used for local ENT therapy.

How to choose a recirculator by power, lamp type, and room volume

For a standard room up to 20–25 m² with a ceiling height of 2.7 m, a model with a capacity of 100 m³/h is sufficient. This ensures the recommended 2–3 air exchange cycles per hour. For spacious offices or rooms with high ceilings, it is recommended to choose models with a capacity of 200 m³/h to prevent air stagnation.

Evaluate the required disinfection intensity. For high-traffic areas, choose models capable of fully renewing the room’s air volume 2–3 times per hour.

Safety rules for using bactericidal recirculators

Operation requires strict monitoring of lamp lifespan, which averages 8,000–9,000 hours. After this period, UV intensity decreases, making the device less effective. When replacing components, avoid touching the glass tube with bare hands, as skin oils can cause clouding under UV exposure, reducing disinfection efficiency and shortening the lamp’s service life.

Advantages and effectiveness of recirculators in Lviv

Main reasons to purchase a recirculator:

• Ability to operate in the background without constant monitoring.
• Low noise level that does not interfere with work or sleep.
• Minimal energy consumption.
• Cost-effectiveness due to long component lifespan and simple maintenance.

Bactericidal recirculators ensure a consistently high level of air hygiene without risk to others. This is a reliable solution for protecting health in any environment.
