100 Diameter Electric Inline Duct Heater 1kW Single Phase
A suitable control scheme must be installed to ensure there is always an adequate airflow through the heater when the heater is turned on and should also include a timer to keep the fan running for 2 minutes after the heater has been shut-off.
Circular duct heaters (heater batteries) are suitable for easy mounting to ductwork and ventilation systems for heating air.
Sheathed element air heaters, provide a safe means of heat transfer using electricity, touching the elements will not produce electric shock. They have relatively low surface temperature (below 400 degrees C)
The heater can be mounted with airflow in either direction with safety cut-outs at the top of unit.
The airflow may be horizontal or vertical and the terminal box may be on the side or top of duct.
Care must be taken to ensure the thermal cut out is near the top of the duct.
The air should be evenly distributed across the duct and the velocity should be above 2.5 m/s. If necessary the duct should be reduced to increase velocity adjacent to heater.
Position the heater away from materials which may be damaged by heat.
A suitable control scheme should be provided and should include a timer to keep the fan running for 2 minutes after the heater has been shut-off.
Every heater is provided with two thermal cut outs.
1. Automatic cuts out at 80 degrees C
2. Manual cuts out at 100 degrees C
Both cut outs must be connected in series with the operating coil of a controlling contactor which will switch off the heater when the current trips.
