Electric air heater ELECTRA 90

wall-mounted

The ELECTRA 90 electric unit heaters with horizontal discharge are made in 7 sizes, with heat outputs from 6 to 36 kW. The electrical heat exchanger has two-stage sealed electrical resistance made of finned steel tubes, to allow part-load operation. The power supply is three phase, 400 V - 50 Hz. The ELECTRAMATIC electric unit heaters with horizontal discharge are made in 5 sizes, with heat outputs from 6 to 24 kW. The electrical heat exchanger has two-stage sealed electrical resistance made of finned steel tubes, to allow part-load operation. The power supply is three phase, 400 V - 50 Hz. These appliances come with an electrical control panel that includes the auxiliary circuits, operating and safety thermostat, and terminal block ready for connection to the line, to the remote control panel and to the room thermostat. • Covering unit made out of stove-enamelled phosphated steel plate panels. • Supporting frame in galvanised steel plate. • Coil with protected electrical resistances, in finned steel pipe. The power is divided into two stages in order to allow it to operate at partialized load. • Helicoidal fan with light alloy, anti-spark blades, directly connected to the motor axis. • Asynchronous 400V - 3f - 50Hz, 6-pole motor, with closed construction, class B insulation and IP 44 protection. • Electrical fan support with sturdy metal basket made of four radial arms and safety mesh basket in round steel pipe. The junction between the support and the rear wall of the casing is created by interposing neoprene anti-vibration supports that ensure operation without vibrations and resonance. • Safety thermostat against overheating.
