The electric duct heating registers are suitable for heating the supply air in the rectangular ventilation systems. The heating registers are used for air heating in the heating, ventilation and air conditioning systems in various rooms. The housing and the switchgear are made of galvanized sheet steel and the heating rods are made of stainless steel. The heating register NK are equipped with two overheating protection thermostats. The main protection with automatic reset and the tripping temperature above +50 ° C.
After cooling, the thermostat automatically closes the control circuit of the heating register. The alarm protection with manual reset and the trigger temperature above +90 ° C.
After triggering, the heating register can only be switched on after the manual alarm reset. The thermal contacts are provided with terminals for external connection. Each standard size has several performance options. The higher output can be achieved by connecting the heating registers in series one after the other.In the heating registers with an output of more than 27 kW, the heating conductors are connected in groups of 9 kW each. Each group consists of 3 heating conductors, which are connected with a?
The heating register is installed with the flange connection. The assembly must be carried out in accordance with the air flow direction (marked by an arrow on the heating register). The heating registers can be installed in any position, except with the electrical shield pointing downwards, as this creates a risk of condensate ingress and a short circuit.It is advisable to mount the heating register in such a way that the air flow is evenly distributed on average. An air filter must be installed in front of the heating register to protect the heating elements from contamination.
The recommended distance between the heating register and the other system elements should at least correspond to the diagonal of the heater. That is, the distance from one corner to another corner in its air duct part.
The duct heating registers are designed for a minimum air flow speed of 1.5 m / s and a maximum air operating temperature of +40 ° C. When using the fan speed controller, the minimum air throughput through the heating register should be ensured. The power supply to the heating register must not be switched on when the valve gate is at a standstill!
For the correct and safe operation of the heating register, the control unit is recommended, which ensures the complex control and protection. The duct heating registers are designed for a minimum air flow speed of 1.5 m / s an.
