EC-3N electric heater

Cabinet

The cabinet is made of sheet steel, coated with a burning varnish. A swivel bracket made of sheet steel is attached to the cabinet, which allows the position of the fan to be adjusted.

Running wheel

The impeller is axial, moulded from Al sheet. The blades are performance optimised.

Motor

The motor is asynchronous with short armature and shielded pole, for continuous operation. The motor has plain bearings with grease packing for life. The motor has overload protection. Protection rating IP24.

El. connection

Connection is by cable which is routed out of the housing through a grommet, the unit is designed for fixed mounting.

Regulation

Regulation is performed externally by the CR 25 switch or by the CR 25 switch and the TR thermostat. Three different operating modes can be selected via the switch (fan only, fan and half heating power, fan and full heating power). If a thermostat is also used, the unit starts automatically in the mode selected on the CR switch. In addition, it is possible to set whether the thermostat starts the whole unit (fan and heater) or only the heater (when the fan is running continuously).

Noise

The values shown in the table are the sound pressure values at a distance of 1.5 m.

Variants

- EC-3N basic design 3 kW/230 V
- EC-5N basic design 5 kW/400 V
- EC-9N basic design 9 kW/400 V
- EC-12N basic design 12 kW/400 V
- EC-15N basic design 15 kW/400 V

Mounting

The unit is mounted on the wall using the hanger included in the delivery. The minimum distances from the walls are shown in the illustration. Care must be taken to ensure that neither the intake nor the discharge side is covered by the housing with the heating rods. In this case, the air flow through the cabinet could be restricted, thus increasing its temperature and causing a fire hazard. If the air temperature rises, the unit will be switched off by the safety thermostat, whose reset button is located on the top of the cabinet. The switch and thermostat are wall mounted.

Instructions

Electrically heated fans are suitable for drying damp areas and for heating in industrial and construction applications. The places of deployment are mainly production halls, warehouse halls, common rooms, churches, exhibition halls, buildings and construction site facilities, garages and workshops.

Highlights

A safe distance from combustible structures, as specified in the user's operating rules, must be maintained.
