INTRODUCTION
" When the HCFC fluids are replaced, these appliance have been
optimized to operate with the R-407C coolant which contains no
chlorine and has no effect on the ozone layer."
1. DEFINITION
The
X 1100
and
X 1900
packaged air conditioners
are presented :
• Single packaged for the
WATER
cooled models
(
AO
),
• with a separate outdoor condensing unit for the
AIR
cooled models (
AR
).
The air intake and discharge is provided :
• either directly by air intake grilles and a discharge
plenum (accessory),
• or by ducts for intake and/or discharge, to be
connected to the connection flanges (accessory).
This well-finished, single packaged unit combines
many features such as east installation, high efficiency,
quiet operation and reliability, which make it well suited
for air conditioning, dehumidification and air filtering
in offices, stores and industrial premises.
These packaged air conditioners can be equipped
with the following accessories :
• Electric heater (integrated or in ducts),
• Hot water coil,
• Fresh air intake (lateral or rear),
• Remote control,
• Air discharge plenum with remote control.
They benefit from 30 years experience and are
perfectly suited to working with :
• Wasted water; its consumption being reduced to a
minimum by a pressure valve (included in the
AO
-
wasted water model).
• Recycled water; supplied by a cooling tower or an
outdoor heat exchanger.
• Outside air; with the possibility of operating at very
low temperatures (down to –10°C with the “ALL
SEASONS” option on the
AR
models).
2. MAIN DATA
• Cabinet with reduced floor dimensions,
• Standard ventilation :
Three fan speeds (high/normal/low) which can be
pre-selected on the terminal block to adapt to the
installations aeraulic pressure losses.
• Equipment option of “High Speed Ventilation” with
a single speed motor.
• Vertical discharge with or without duct, or horizon-
tal discharge with plenum (accessory).
• Two air intake possibilities :
On the front with grilles or on the rear with ducts,
with the rear air intake (accessory).
• M1 flame retardant filters, mounted on a metal frame
with stiffening netting.
• Integrated unit controls (Control Panel) or remote
control (accessory).
• Electrical, water and refrigerant pipe connections
on the right or left side.
• Cooling with wasted water with a pressure valve or
recycled water without a valve.
• Possibility of running in Cooling mode down to an
outdoor temperature of –10° C for the
AR
models
with the “ALL SEASONS” accessory.
• Two heating possibilities (accessories) :
Integrated electric coils or hot water heating coils
• Three control possibilities :
Inverting type (standard), automatic thermostat for
“heating/cooling” with neutral zone (accessory
supplied with integrated electric heating) and air
monitoring control (remote control accessory).
• Two refrigerant connection pipe possibilities (
AR
models): up to 25 m maximum with factory pre-
charged pipes (accessory) or with pipes brazed and
charged on site (set of female valves supplied as
an accessory for connections up to 45 m).
3. DESCRIPTION
3.1 Bodywork
• Panels and side faces made of profiled sheet steel
covered with enamel finish, baked in a high
temperature oven.
• Intake grilles made of modular elements in
flameproof, shock resistant polystyrene, classified
UL-VO according to UL94.
3.2 Insulation and protection

3.2 Insulation and protection
3.2 Insulation and protection
• Thermal and acoustic insulation of the unit.
• Watertight unit base for the possible collection of
condensates or abnormal overflowing (e.g.
condensate drain tray clogging).
3.3 Refrigerant circuit
• All models
– Hermetic type compressor fitted with thermal and
electrical protections, liked to a factory sealed
and brazed cooling circuit.
– Pressostats and high and low pressure measu-
rement Schrader valves.
– Liquid circuit protected by a strainer (
AO
model)
or by a filter (
AR
model)
– Copper tube evaporator with aluminium fins and
anti-corrosion protected condensate tray.
· AO Model
– Coaxial condenser with counter flow circulation,
equipped with finned copped tube in a steel cover.
– Pressure valve on the water inlet for reducing water
consumption to a minimum (wasted water model).
– On request, the unit is supplied without a pres-
sure valve but with an additional Schrader valve
connection for independent control of the water
flow (recycled water model).
