Description of the unit
The rooftop units of the RTE range have
been designed taking into account the
precise needs of the plant engineering
sector, that deals with large structures for
the “large-scale retail trade“ (supermarkets
and hypermarkets), and areas dedicated to
exhibitions, trade fairs, and industrial use
in general.
These units, usually positioned on roof-
tops or anyway out of doors, offer the
following main advantages:
• their installation on the roof does not
reduce the effective space available;
• they offer the maximum modularity,
therefore allowing you to distinguish
the treatment in different volumes with
different usage characteristics (food sec-
tion, clothing department, etc.);
• they offer high levels of environmental
comfort, controlling not only the tem-
perature but also the exchange, filtering
and humidification or dehumidification
of the air;
• the environmental noise level is kept
down thanks to the careful soundproo-
fing of the machine.
Components
The RTE rooftop units are all available in
the cooling-only version (RTE F) or coo-
ling + heat pump (RTE H).
The RTE rooftop units are supplied com-
plete with:
• condensing unit with helicoidal fans and
scroll compressors;
• cooling circuit with thermostatic valves,
filters, liquid indicator lights;
• corrugated synthetic filter, class G4
(EN779);
• direct expansion coil with condensate
collection tank in aluminium alloy;
• centrifugal supply fan, with blades for-
wards or backwards blades depending
on the model and the pressure levels
required, with belt transmission and
variable pulley;
• adjustment by means of microproces-
sor;
• electric panel.
Sizes
The units of the RTE range are available
in 5 sizes (480-560-600-700-800), with
the possibility of standard, low noise L
or high temperature A operation (exclu-
ding sizes 200 and 255). With a suita-
ble combination of the numerous options
available, it is possible to configure each
model to satisfy the most demanding plant
requirements.
Available configurations
Note: the figures shown refer to the
dimensional diagrams on pages 23-26
Standard configuration: a single-block
rooftop unit with flat G4 filters (efficiency
level in compliance with EN779), evapo-
rator coil (optional hot water coil) (fig.1)
SMP: rooftop unit with 2-ways mixing
box, rear intake (1) (fig.2)
FT7: rooftop unit with flat G3 pre-filters
and F7 rigid bag filters (EN779) (fig.3)
SM2: rooftop unit with 2-ways mixing
box, side/lower intake (1) (fig.4)
SM3: rooftop unit with 3-ways mixing box
with actuators and free-cooling for the
temperature (fig.7)
REC: rooftop unit with plate heat recove-
ry unit (with recirculation damper) and
intake fan. The air/air heat recovery unit is
of the static plate type with cross flows. It
allows the recovery of sensitive heat from
the expelled air with an efficiency level
higher than 50% during winter operation.
The two air flows (expulsion and intake)
are completely separate, thereby avoiding
any form of contamination. Modulating
actuators included as standard (fig.13)
Gxxx: rooftop unit with condensing hot
air generator. The condensing hot air
generator is powered by natural gas. The
air is heated as it passes over the surfa-
ce of the combustion chamber and the
exchange pipes. The combustion chamber
is built entirely of AISI 430 stainless steel,
while the surfaces in contact with the
condensate (heat exchanger, flue gases
collection hood) are made of AISI 304 L
steel to be particularly resistant to corro-
sion. It is fitted with a safety thermostat
with automatic reset (fig.6).
The cooling circuit will be switched off
when the hot air generator is working.
It is not possible to combine the hot air
generator with the electric heating ele-
ment.

Description of components
Cooling circuit
Compressors
Scroll-type tandem hermetic compressors fit-
ted (in heat pump versions) with electric he-
ater.
The heater is automatically powered when the
unit stops, as long as the unit is still powered
up.
Refrigerant
RTE roof-top series uses R410A ecological re-
frigerant.

blocked by the mechanical expansion of the
pipes. Different material and fins treatment
upon request.
Liquid receiver
(only for heat pump version)
Thermostatic valve
The valve with an external equaliser (located
at the evaporator outlet) modulates the flow of
gas to the evaporator on the basis of the ther-
mal load, thereby ensuring a sufficient level of
overheating of the intake gas.
Filter-drier
It is of the mechanical type, made of ceramic
and a hygroscopic material able to hold back
the impurities and any traces of humidity in the
cooling circuit.
Sight glass
Allows you to check the amount of refrigera-
ting gas and any humidity in the cooling cir-
cuit.
Reverse cycle valve
(only for heat pump version)
Inverts the flow of refrigerant to the change of
the summer/winter function and during the de-
frosting cycle.
Safety valves of the cooling circuit, assembled
on the high and low pressure side: these in-
tervene, discharging the over pressure in the
event of abnormal pressure levels.
One-way valves
(only for heat pump version)
These allow the refrigerant to travel in one di-
rection only.
Frame and fans
Condensation ventilation unit
Of the helicoidal type, statically and dynami-
cally balanced. The electric fans are electri-
cally and mechanically protected with metal
anti-intrusion grilles.
Treatment fan unit
Centrifugal fan with double intake and for-
ward-curved blades for higher efficiency and
less noise, statically and dynamically balan-
ced, activated by three-phase electric motors
joined with trapezoidal belts and pulleys that
can be adjusted at variable steps.
Load-bearing structure
The construction form for the air treatment
side is: sandwich-type panelling with alumi-
nium alloy on the outside and galvanised steel
on the inside, 50mm thick with injected po-
lyurethane insulation (density 42kg/m3).
Safety and check components
Door-block disconnecting switch
For safety purposes, it is only possible to ac-
cess the electric panel when the power is di-
sconnected (by means of the opening lever on
the electric panel itself). This lever can be blo-
cked with at least one padlock during main-
tenance work, to prevent the machine being
unintentionally powered.
Control keypad and monitor on the machine
This allows the unit to be fully commanded.

60204-1 and the electromagnetic compati-
bility directives EMC 89/336/EEC and 92/31/
EEC.
Anti-freeze probe (only with BTR accessory)
When the water temperature is lower than
+5°C, the special software in the adjustment
card will fully open the 3-way valve (if pre-
sent), allowing the circulation of hot water via
the digital output signal.
Cooling circuit pressure switches
These are located on the high pressure side of
the cooling circuit. They stop the compressor
working in the event of abnormal work pres-
sure levels.
High and low pressure transducers
These are located on the high and low pres-
sure sides of the cooling circuit and allow you
to visualise the pressure value on the monitor.
The low pressure transducer also stops the
compressors if the pressure level falls below
the low pressure alarm setting.

Variations in the cooling capacity and input power
The following diagrams allow you to
obtain the correction coefficients to be
used for the rooftop units in cooling
mode. In line with each curve, there is
the external air temperature (Te).
The total cooling capacity output, the
sensible cooling capacity, and the elec-
trical input power in conditions other
than nominal are obtained by multi-
plying the nominal values in the techni-
cal data tables by the respective correc-
tion coefficients (Cft, Cfs and Cpa).
