ROOFTOP  R407C

PACKAGED AIR TO AIR ROOFTOP UNITS

WITH SCROLL COMPRESSORS

 rtr-rtp-GB•rel.1.3

The units of RT series have been conceived to be extremely exible and to oer a

wide range of custom-made options.

They are direct expansion and packaged air to air units, suitable for outdoor in-

stallation, realized with two independent cooling circuits, designed for air condi-

tioning 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, shopping malls, exhibition halls, restaurants, hospital, facilities of food

production and conservation and laboratories.

The available versions are the following:

RTR…K only cooling

RTP…K heat pump

Depending on the dierent air treatment requests, the units can be realized in the

following four congurations, better indicated in the following pages:

2S … Mixing of re-circulating and external air (2 dampers)

This conguration 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 by motors, so to make possible, the operation with all re-circulating air,

with a mixing of re-circulating air 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 condi-

tions (free-cooling operation) or to the quality of the internal air.

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 on. The unit is

pre-arranged for the air inlet directly from ambient.

TES… Possible mixing with heat recovery and free-cooling (not available

for all units)

This conguration is made of two sections with centrifugal fans and a 4-way mix-

ing box. Depending on the position of the mixing box’s dampers, the external

fan section extracts the treated air, which before being exhausted, directly runs

into the evapo-condensing coil and transfers part of its enthalpy content, with a

remarkable increase in term of eciency and energy saving.

Operating limits (standard unit):

RTR – air from 20 to 42°C

RTP – SUMMER: air from 20 to 42°C; WINTER: air from 15 to -10°C

RTR…K – RTP...K Series

Two refrigerant circuits - Cooling capacities from 64 to 406 kW

RTR 1292 3S.K
