Selen II type air handling units have been designed to increase comfort in the use of ventilation. The recuperators are made of the highest quality components, ensuring a very high level of filtration and heat recovery. Inside the unit there are G4 (EU4) filters with silver nanoparticles with a high filtration level and two cross-counter-current heat exchangers. Selen II is a recuperation unit with two cross-current heat exchangers of high efficiency. The structure of the heat exchanger has been designed in such a way that the streams, transferring heat, do not mix with each other. Thanks to the very large total surface of the plates, we achieve heat recovery efficiency of up to 95%. The flow of streams is controlled by an advanced controller that enables smooth adjustment of fan speed and weekly programming.
