The range of close control units with in-built free-cooling system of  packaged and direct expansion type (ED.P SF series) or with remote condenser (ED.A SF series) or of chilled water type (UV SF series) is particularly indicated for use in technological centres, data processing rooms, in telecom centres and in such applications where it is important to  keep the thermo-hygrometric conditions constant all over the year, so to assure the correct operation of the equipments installed in these sites.Depending on the cooling capacity, they are available with 1 and 2 cooling  circuits. Thanks to their technologically advanced design, these close control units are able to control the ambient temperature with remarkably high precision  and, when the humidity level is required, to adapt their cooling capacity to  the room requirements, all automatically managed by the microprocessor  on board. The high technology employed during their design together with the use of the best components available on the markets, make these units extremely reliable and therefore able to work for long periods, without a break.These units are particularly easy to install also in small spaces and  easily accessible on the front side for ordinary and extraordinary service operations.They are completely assembled and tested in the factory and supplied with nitrogen charge.
These units are available as follows:
