Vents KSA-U Box Fan with Automatic Thermostatic Control by Vents

KSA-U Box Fan with Automatic Thermostatic Control Vents
Starting at £203.99

Compact sound- and heat-insulated centrifugal fans with forward-curved impeller blades and the air capacity up to 2140 m3/h. Applied in supply and exhaust ventilation systems for premises with high requirements to noise level.

Design

The fan casing is made of aluzink. Heat- and sound-insulating layer is made of polystyrene foam.

Motor

The impeller made of galvanized steel and forward curved blades is powered by means of the 2- or 4-pole asynchronous motor with external rotor. The motor is equipped with the ball bearings for long service life. For precise features, safe operation and low noise, each impeller is dynamically balanced while assembly. Motor protection rating IP 44.

KSA fan with electronic module for speed control with temperature sensor

KSA fan with electronic module for temperature and speed is the perfect solution for greenhouses and other premises requiring air temperature control. Fans marked KSA…U fitted with TSC electronic speed control module with temperature sensor provide automatic speed regulation as a function of air temperature in the duct. Temperature and minimum speed can be adjusted with two control knobs on the controller panel. The fan can be supplied with the external duct temperature sensor with 4 m cable and a cover for mechanical damage protection. The LED indicator for thermostat switching on is placed at the front panel of the fan.

Automatic speed controller pattern for KSA fans

Set the desirable threshold temperature value for thermostat switching on by means of rotating the control knob. Normally the fan operates with the speed which is set with the knob. If the temperature exceeds the set point, the fan boosts to the maximum speed producing maximum air capacity. After that when the temperature drops down below the set point, the fan goes back to preset speed. The switching delay disables frequent motor switching (if the set temperature in the duct is equal to the threshold temperature).

There are two patters of delay that may be used in various cases:

  1. Temperature sensor delay (KSA…U): if the temperature rises by 2°С above the set threshold of thermostat actuation, the motor switches to the increased rotation speed. The motor switches to the preset (low) speed as the temperature drops below the set threshold of thermostat switching on. This pattern may be used to keep air temperature to within 2°С. In this case fan switches are rare.
  2. Timer delay (KSA…U1): the motor sets to higher speed 5 min after the temperature exceeds the set threshold. The motor switches to the preset (low) speed 5 min. after the temperature drops below the set threshold. This pattern can be used to keep the air temperature at a precise level. In this case the fan switches more frequently than in the pattern of temperature sensor delay, but the intervals do not exceed 5 minutes.
