Specications
General
The new SYSAER R32 units have been designed and
optimized to operate with R32 refrigerant uid. They
are of single refrigerant circuit type.
They are available in reversible version.
The range consists in 3 sizes (SR R32 105, SR R32
120 and SR R32 140) and covers a nominal cooling
capacity range from 106 to 139 kW and a nominal
heating capacity range from 106 to 142 kW.
All the units consist of two refrigerant circuits
equipped with scroll mono-compressor to constantly
adapt to the partial loads of the system.
The general operation status of the machine is
continuously under the control of an IATC controller.
Cabinet and structure
The cabinet and structure of the unit are of heavy duty
galvanized steel. All galvanized steel components are
individually painted by a special painting process
before the assembly of the unit.
This painting system performs a homogeneous
protection to the corrosion. The painting is a polyester
powder based type, coloured in RAL 7040.
The units SYSAER R32 are equipped with double
skin panels as a standard to prevent insulation
ber entering into the building and harmful build-
up of bacteria or contaminants. It also ensure better
thermal insulation
Specications of glass wool:
² Conductivity : 0.035W/(m.K) at 20°C
² Thermal resistance : 0.714 m².K/W
Control and maintenance operations are facilitated
thanks to all of the doors and access panels. Opening
and closing are done with a simple triangular key.
Extractable drain pan under indoor coil, to allow for
hygienic cleaning.
Compressors
Each unit is equipped with two scroll
mono-compressors tted on a rail and assembled
together to form tandem compressors.
The compressors are then mounted on rubber pads in
order to eliminate noise and vibration transmissions.
The compressor motors have a direct start-up. Each
motor is cooled by the refrigerant gas and is equipped
with an overload protection.
Crankcase heater on each compressor to eliminate
refrigerant migration and allow for safe start up in
winter.
A phase sequence monitor is supplied as standard.
Outdoor coils
The outdoor coils are a nned coil constructed with
seamless copper tubes mechanically expanded into
aluminium ns. The ns of SYSAER R32 coils are made
of aluminium with hydrophilic blue coating to facilitate
water droplets drain in the event of defrosting.
Outdoor coils are largely dimensioned in order to
optimize performance and defrosting cycles.
Outdoor coils designed for low air resistance to reduce
axial fan power consumption and noise level.
Outdoor coils are equipped with a protective grille to
prevent shocks.
Each SYSAER R32 has axial fan, with 2 speeds.
The fan motor has IP54 grade and is equipped with a
thermal overload protection.
A pressostatic type fan speed controller can be
delivered as factory-tted option. It allows the unit to
operate in cooling mode at low ambient temperatures
down to -10 °C minimum, because it regulates the fan
speed in order to maintain the constant condensing
temperature.
All fans are tted with a protective grille on top.
