The fan casing is made of aluzinc.
For easy installation and operation, the fan is attached to the surface using a special bracket.
Heat- and sound-insulation made of foam.
The round connecting spigots are rubber sealed.
The fan is equipped with an asynchronous electric motor with an external rotor and an impeller with forward curved blades.
The low-noise electric motor with ball bearings with specially selected grease ensures maintenance-free operation of the fan.
The duct fans are intended for mounting to round air ducts.
The fans are installed between the air ducts.
The fan is attached to the building structure using a bracket.
The fan may be installed in any position in consideration of the air flow direction (as indicated by the arrow on the fan casing).
DESIGN AND FUNCTIONING
ELECTRONICS OPERATION ALGORITHM
The
KSA U (U1) fan
is equipped with an electronic speed controller with a TSC electronic thermostat for automatic air flow control
depending on the air temperature.
The electronic speed controller has 2 control knobs: for setting the motor speed and for setting the electronic thermostat.
The light indicator of the thermostat operation is located on the fan cover.
To set the thermostat threshold, turn the thermostat control knob clockwise to increase or counter-clockwise to decrease the temperature
set point.
To set the fan speed, turn the speed control knob in the same way.
The KSA U control algorithm by temperature:
The fan maintains air temperature with an accuracy of 2 °C.
When the air temperature rises to the set temperature, the fan switches to high speed.
If the air temperature drops 2 °C below the set point or if the initial air temperature is lower than the set temperature,
the fan continues to run at low speed.
The KSA U1 control algorithm by timer:
The fan maintains air temperature with high accuracy.
The fan changes its speed more often compared to the previous control algorithm, but the minimum operating time at one speed is at
least 5 minutes.
When the air temperature rises to the set value, the fan switches to maximum speed.
The switching delay timer synchronously starts for 5 minutes.
If the air temperature drops below the set point, the fan speed will change to a lower one only in 5 minutes.
If the initial temperature is lower than the set one, the fan will continue to operate at low speed.
The
KSA P fan
is equipped with a speed controller that allows turning the fan on/off and smoothly adjusting the air flow rate from
minimum to maximum speed.
