SYSAER R32 Key Points Energy class A, EC PLUG FAN for supply air and AC FAN for extract air, Ecodesign 2021, 2 filters stage R32 refrigerant, High SEER and SCOP, ² G4 2 circuits for the entire range to optimize performances at part load, and avoid cold draught during defrost mode. ² F7 / F9 1 energy recovery system ² The range SYSAER R32 is provided with 2 compressors, 1 per circuit.
2 SYSAER R32 Specifications General Compressors The new SYSAER R32 units have been designed and optimized to operate with R32 refrigerant fluid. They are of single refrigerant circuit type. Each unit is equipped with two scroll mono‑compressors fitted on a rail and assembled together to form tandem compressors. They are available in reversible version. The compressors are then mounted on rubber pads in order to eliminate noise and vibration transmissions.
SYSAER R32 Specifications Blast and return fan The SYSAER R32 is provided with blast and return fans, PLUG FAN type with an AC (Asynchronous) motor or with an EC (Electronic Switching) motor, Low Pressure or High Pressure according to the configuration selected by the customer. Economiser with 2 dampers The factory-mounted economiser with 2 dampers is available with the R1, R2 and R4 configurations.
4 SYSAER R32 Specifications Heating Frame The SYSAER R32 can be equipped, according to the specifications of the customer, with an additional heating system. This equipment is installed and tested in the factory. The mounting frame is made from galvanized steel sheet. It is delivered with a seal to connect the edge of the frame to the unit and eliminate vibrations and thermal bridges. Electric heating The electric heating battery is available on all of the configurations of the SYSAER R32.
SYSAER R32 Specifications Control The IATC is equipped with clock card for scheduler programming. This card can be programmed on site in comfort-economy modes with a reduction in the ambient temperature and in the ambient humidity. The user interface also contains a backlit semigraphic liquid crystal display screen with 8 lines and 22 columns. This display shows the current values, setpoints, operating times and alarms.
