The Covid-19 virus can be spread through air. Central air-conditioning, heating and ventilation systems (HVAC) in buildings are designed to recirculate air in the building. In a central unit the air is partly refreshed (incoming air stream from outside), treated and blown back into the building. In recent years there has been focus on reduction of the energy cost (cooling/heating) and only a small portion of the recirculated air is refreshed with outside air during this process. Given the current Covid-19 situation this is a huge problem.
One solution to avoid Covid-19 spread is to stop recirculation completely and only ventilate using 100% fresh outside air. This has a huge impact on energy costs though and also the heating/cooling system has to be changed to increase capacity at high costs.
The other solution is effective and simple. Position a UV-C disinfection treatment unit in the return duct/channel that blows the air back into the building.
UV-C is the most effective technique to inactivate Covid-19 virus. By adding the unit inline in the existing Heat Ventilation Air-Conditioning system you:
The selected system is custom made. You can send the specifications of your current HVAC system to ClearSafeProducts online. Based on that info a software program calculates the required UV-C treatment to ensure >99.99% Covid-19 reduction. The solution can be produced and your installation company can add the inline system onto your existing HVAC system. Read more about this Inline solution and advantages here.
