Range of free-cooling units is a series of air cooled
packaged water chillers with double screw type compressors, equipped
with an new free-cooling integrated system with independent aeraulic
circuits with very high energy efficiency.
Free-cooling is the best system for obtain high savings in electrical
energy and it is particularly indicated in the industrial process cooling
where the production of water cooled is required all year long.
It consists in to exploit, in winter time and during the intermediate
season, the low temperature of external air to cooling completly or only
a part the water of process cooling is normally cooled through the
During free-cooling functioning these chillers use an logical modulated
type where the free cooling of the water can happen every seasons of
the year, with compressors OFF (total free-cooling), or with compressors
partially ON (partial free-cooling).
The free-cooling units have one or two independents cooling
circuits and one compressor for circuit. The refrigerant gas utilized is
The management of each free-cooling isentrusted to a
microprocessor control which enable the management of all the
components and the functioning parameters of units; In case of alarm an
internal memory record the functioning conditions at the time that is
The free-cooling units have power supply 400/3/50, an
protection rating IP54 and are therefore suitables for outdoor
Top quality brand components are carefully selected for these chillers
that are designed, produced and tested in compliance with ISO9001.
