ROOFTOP  R407C

PACKAGED WATER TO AIR ROOFTOP UNITS

WITH SCROLL COMPRESSORS

 rtr.w-rtp.w-GB•rel.1.3

The units of this range have been conceived to be extremely exible and to oer

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

following three 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 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

RTR….W.K – RTP...W.K Series

2 refrigerant circuits - Cooling capacities from 70 to 474 kW
