Application
The heater is designed for integration into a ventilation system and joint operation with an air handling unit equipped with a control system used to switch on the heater and control its operation. The heater maintains the supply duct air temperature at a point set by the unit controller.
Design
The casing, the junction box and the heater cover are made of galvanized steel with the heating elements in stainless steel.
The heater casing is additionally heat-insulated with 20 mm non-flammable mineral wool layer. The heaters are equipped with rubber seals for airtight connection to the air ducts.
The NKD duct heaters are equipped with a power and a signal cable for connection of the heater to the air handling unit controller.
The temperature is controlled by a triac power controller by means of switching the full load on and off. Load commutation is carried out by the semiconductor device (triac). The heaters are equipped with overheat thermostats:
- main overheat protection with automatic reset at +50 °C
- emergency overheat protection with manual reset at +90 °C
Mounting
The heater design ensures its mounting on the round ducts in any position by means of clamps (included in delivery).
The air flow direction shall match the direction of the arrow on the heater casing.
The heater is connected to the air handling unit controller using the cable with connectors.
In case of horizontal mounting the control box must be installed with the cover upwards.
Swivel range from the normal position up to max. 90°. Do not install the control box with the cover downwards.
