APPLICATIONS INTEGRATED FUNCTIONS AND CONTROL
  • Supply and exhaust ventilation and air conditioning systems for various premises requiring cost-effective solution and controlled ventilation.
  • EC motors in VKP fan reduce energy consumption by 1,5-3 times and ensure high performance and low noise level.
  • Such characteristics are of special importance for ventilation of banks, supermarkets, restaurants, hotels and other public facilities including swimming pool ventilation.
  • The fans are compatible with 300х150, 400х200, 500х250, 500х300, 600х300, 600х350, 700х400, 800х500, 900х500, 1000х500 mm rectangular ducts.
  • The fan is controlled with the external control signal 0-10 V (air capacity as a function of temperature level, pressure and smoke conditions etc).
  • Should the control value factor get changed the EC-motor changes its speed and the fan boosts as much air capacity to the ventilation system as required.
  • Maximum speed of the fan does not depend on the current frequency and it can operate at 50 or 60 Hz mains supply.
  • The fans can be integrated to the unified PC control system. The respective software allows controlling all the fan units with high accuracy and setting particular operation mode for each fan.
 DESIGN  MOTOR
  • Fan casing is made of galvanized steel.
  • All inner components are interconnected by means of rivets.
  • The fan is equipped with 20 mm standard flanges.
 MOUNTING
  • The fans are mounted into the rectangular ducts.
  • The fans can be mounted in any position with respect to the airflow direction which is indicated with a pointer on the casing.
  • Access for the fan maintenance shall be provided.
  • The casing is equipped with a removable access door for inspection and maintenance purposes.
  • The impellers with backward-curved blades are powered with high efficient electronically commutated (EC) direct current motors with external rotor. As of today, such motor type is the most advanced solution for energy saving. 
  • EC motors in VKP fan reduce energy consumption by 1,5-3 times and ensure high performance and low noise level.
  • EC-motors are featured by high performance and the optimal control over the whole range of fan speeds.
  • Premium efficiency reaching up to 90% is an absolute advantage of electronically commutated motors.
