PURPOSE |
|
-
For example, the unit design includes a possibility of space-restricted installation above suspended ceilings.
-
The KSB EC fans are designed for mounting into Ø 100, 125, 150, 160, 200, 250, 315 mm air ducts.
|
DESIGN |
|
|
MOTOR |
-
The unit is equipped with high-efficient external rotor EC motors and centrifugal impellers with backward curved blades.
-
These motors currently are the most cutting-edge solution in the field of energy conservation.
-
The use of EC motors allows to reduce the electricity consumption by 35% approximately while providing the high capacity and low noise level.
|
-
The EC motors are featured with high performance and totally controllable speed range.
-
The high efficiency (up to 90%) is a definite advantage of the EC motors.
-
The motors are equipped with rolling-element bearings that provide a longer operation period (40000 hours).
|
SPEED CONTROL |
-
The fans are controlled by means of a 0-10 V external control signal while the performance regulation is based on the feedback from the temperature, smoke and other sensors as well as other vital parameter settings.
-
As the control signal changes the EC fan changes speed accordingly to supply the exact air amount required by the ventilation system.
|
-
The maximum fan speed does not depend on the electric mains frequency enabling compatibility with both 50 Hz and 60 Hz networks.
-
The fans can be easily combined into a single computer-controlled network.
-
Special software allows for precise control over the operating parameters of the network units.
|
MOUNTING |
-
The fans are intended for installation in round air ducts. They are installed between the air ducts.
-
The use of flexible connectors requires fixation of the fan on the building structure by means of supports, mounts or fixing brackets.
-
The fan can be fixed in any position, taking into account the air flow direction indicated by the arrow on the fan casing.
|
-
While mounting the fan provide enough access for servicing and repair operations.
-
Electrical connection and installation must be performed in accordance with the instruction manual and the electrical connections diagram applied to the terminal box.
