Page 4: General Information
1. GENERAL INFORMATION 1.1 APPLICATIONS Fan coils are used to directly treat the air in the room where they are installed. They can be used both for heating and cooling applications; in the latter case, the air is also dehumidified. 1.2 OPERATION The effectiveness of a fan coil is due to the large surface area of the finned heat exchanger (coil) where the air drawn from the room by the fan passes through. -
Page 5: Product Range
To facilitate choosing the correct size of a fan coil for any operating condition (including those differing from the standard ones), EURAPO offers a dedicated computer program which can be downloaded from the ftp address http://ftp.eurapo.it/ and can be updated with automatic upload through internet. -
