1 MAIN FEATURES

The S 80 series fan heaters are suitable for heating medium-sized

to large environments such as warehouses, industrial or commercial

premises, gyms, etc.

The S 80 series consists of 16 models for hot or overheated water

operation, 9 of which are suitable also for steam operation.

S 80 series fan heaters comply with the provisions of EEC ( )

Directives 73/23, 89/392, 91/368, 93/44, 93/68.

They are made of:

heat exchanger: consists of copper tubes and aluminium fins

secured to the tubes by mechanical expansion with steel hydraulic

connections;

fan: dynamically and statically balanced helical type, made of anti-

spark aluminium, keyed directly onto the motor;

motor: three-phase asynchronous enclosed type motor with IP 44

protection rating and class B windings, in single and dual speed

versions:

- for models from S 610 to S 841

4 poles (1400 rpm)

6 poles (900 rpm)

4-8 poles (1400/700 r.p.m.)

- for models S 1110 and S 1120

6 poles (900 rpm)

8 poles (700 rpm)

6-8 poles (900-700 rpm)

motors with the following characteristics can be supplied to order:

- 230 V single-phase power supply with permanently activated

capacitor

- protection rating IP 55

- tropicalised construction

- explosion-proof construction EEx-d IIB T3

- 4/6 pole dual-speed motors

the motor is placed vertically inside a steel sheet cone which

protects it from the heat radiated by the heat exchanger.

The available accessories are:

- truncated cone diffuser

- anemometric diffuser

- deflecting fin diffuser

OPERATING LIMITS

Maximum water temperature +160°C

Maximum operating water pressure 15 bar

Maximum steam pressure 6 bar

Air inlet temperature min/max -10÷40°C

Power supply voltage +/- 10%
