Healthy breathing air on passenger ships

On passenger ships, especially in public areas such as rest rooms, restaurants, corridors and fitness rooms, many people come together in limited air space.

Respiratory infections account for 50% of illnesses on board. The corona epidemic has shown the risks that a single infected person can pose when they are in closed environments.

With oxytec, the risk of infection can be almost completely eliminated, thus ensuring the operational safety of the ship.

Air management on ships

The communal rooms on ships, which are largely sealed off from the outside, are supplied with fresh air via individually calculated air conditioning systems.

To control temperature, wind and humidity, these systems supply passengers and crews with a defined quota of breathing air, tailored to a large number of people in a confined space.

According to the ASR (technical rules for workplaces), a fresh air supply is necessary if the air quality inside does not correspond to the outside air quality. The benchmark is the so-called MAK values (maximum workplace concentration) with regard to CO2, odors, pollutants, solvents, ozone from laser printers, dusts, gases, vapors and other factors.

Clean cabin air with UV or plasma technology

oxytec places UV-C disinfection modules in the air handling units – with a comprehensive effect: the UV light, which is precisely defined in terms of wavelength, neutralizes germs of all kinds. Air pollutants and allergens in the air we breathe are also captured, as are odor-causing molecules. This also provides protection against the dangerous norovirus. Organic molecules are broken down under the influence of UV-C light and react to form harmless odorless substances such as water vapor and CO₂. This also prevents unwanted deposits from forming in the ducts, which can lead to problems later on.

Door safety switches on the air handling units ensure that no one is exposed to UV-C radiation in the event of unauthorized access.

Scientifically proven effect

During the corona pandemic, the effect of UV-C air purification from oxytec was tested under real conditions by the Fraunhofer Institute:

99.9% of all germs are eliminated with a single pass through the UV-C lamps.

Project planning

We plan an individual solution tailored to your needs in advance. In addition to the use, room size and existing systems, the air temperature, relative humidity and air speed are also taken into account.

UV-C disinfection modules can be used as a supplement to existing filters (F5/F7) to significantly and sustainably reduce the concentration of viruses and other microorganisms in HVAC systems.

oxytec UV-C modules are available in dimensions ranging from 450 – 1700 mm in length to suit standard air handling duct dimensions. They can generally be easily integrated into existing and newly planned air handling units.

UV-C disinfection modules are particularly recommended in systems that work with high recirculated air proportions if the temperature and CO₂ value in the room correspond to the specified values. Safe air recirculation by preventing the concentration and distribution of microorganisms is economically efficient because, unlike filters, UV-C modules do not cause a pressure drop. Furthermore, the required cooling capacity, dehumidification and, if necessary, desalination of the supply air can be reduced at the same time as the proportion of recirculated air increases.

Installation

  • Simple installation: The UV modules are optionally supplied with a frame construction, hooked in and connected to the power supply with the plug.
  • Electronic ballasts are integrated, the complete UV system is pre-installed. External ballasts outside the air flow are only required for applications.
  • Protection class of the UV-C system: IP 54
  • The cables to the modules are protected from the UV rays by a stainless steel protective tube.
  • To clean the housing of the air handling unit and to replace the lamps, the plug connections must be disconnected and the modules in the frame must be clicked out.
  • The UV-C modules are supplied with power via the control cabinet (CB-Mini/Maxi), which in turn can be easily adapted to the existing electrical system – even if there is no “N”. The control cabinets are also insensitive to the usual voltage fluctuations on ships.
  • The control cabinet is connected “hard wired” for signal exchange with the ship’s automation system. The status of the system, operating hours and error messages can also be read on the control cabinet display.
  • Service life of the lamps 12.
