rtr.w-rtp.w-GB•rel.1.3
The units of this range have been conceived to be extremely exible and to oer
a wide range of custom-made options.
They are direct expansion and packaged water to air units, suitable for outdoor
and indoor installation and for water source systems, realized with two inde-
pendent cooling circuits, designed for air conditioning of quite large areas, pre-
arranged to be connected to the air distribution ducts.
They represent, therefore, both from the performance and the economical points
of view, the ideal solution for the summer cooling and the winter heating of su-
permarkets, commercial centres, exhibition halls, restaurants, hospital, facilities of
food production and conservation and laboratories, where a water source sys-
tem is present.
The available versions are the following:
RTR…W.K only cooling
RTP…W.K cycle inversion heat pump
Depending on the dierent air treatment requests, the units can be realized in the
following three congurations, better indicated in the following pages:
2S … mixing of re-circulating and external air (2 dampers)
This conguration allows the mixing between the treated and the external
air. There is an adjustable damper on the external air inlet for a correct mixing;
the damper is pre-arranged for motorization. Usually this damper is ducted; on
the contrary, it is possible, on demand, to supply a weatherproof protection. On
the ambient air inlet there is a damper, also pre-arranged for motorization. The
treated air ow is assured by the roof-top discharge fans, while the eventual ex-
haust from the ambient, so to avoid overpressure problems, must be provided
externally to our unit.
3S … mixing of re-circulating and fresh air and exhaust of the exceeding
internal air through a suitable fan (3 dampers)
The version 3S is similar to the previous one, with an additional section and cen-
trifugal fan, assuring the correct circulation of the inlet air. There is therefore no
need to take out air from the ambient. The unit is provided with two dampers
for the exhaust of the foul air and for the inlet of the fresh air, plus a third internal
damper for the re-circulating air. The three dampers are co-ordinately hand con-
trolled so to make possible the operation with all re-circulating air, with a mixing
of re-circulating and external air or with all external air and total exhaust of the
ambient air. The control of the dampers can be managed by an external signal
0-10V, or on demand, according to the thermo-hygrometric conditions (free-
cooling operation).
TR … all re-circulating air (no mixing between re-circulating and external
air)
This is the basic version on which the 2S and 3S versions are based. The unit is
pre-arranged for the air inlet directly from ambient.
Operating limits (standard unit):
RTR.W - AIR from 20 to 42°C - WATER from 25 to 40°C
RTP.W - SUMMER: air from 20 to 42°C - WATER from 25 to 40°C; WINTER : AIR
from 15 to -10°C - WATER from 5 to 17°C
