Ceiling mounting / Vertical flow with free cooling

From 2,0 to 13,8kW

The conditioners Under Series are air cooled split system, ideal for installations inside room, shelter for radio base station and data processing centre.
The adjustment of the temperature is got by means of the cooling capacity variation of the air conditioner through Inverter technology (rotation speed variation of compresor).
The airflow of the internal unit it is directed downwards.
The air conditioners are equipped with internal controller and temperature and pressure probes, that allow to get an independent or coordinated “cooling system”, assuring a complete redundance of all the control and conditioning functions.

The air conditioners are provided with remote interface user panel for the manage of commands and controls, complete with disconnectors, with internal electrical protection for overcurrent. Due to their mechanical characteristics, all the indoor units can be installed adjacent even with different cooling capacities.

This equipment is provided with free-cooling (FCUP). In case of need for ducting the free-cooling module, on request it can be provided a ducting diam. 250mm (L max 5mt) and an external grid equipped with plenum on the air inlet side. The FCUP module is a separated element from the indoor unit and its mechanical characteristics make it particularly flexible in terms of positioning and installation.
