KBR 280EC THERMO FAN

• Highly efficient EC motors
• 100% of speed regulation
• Built-in motor protection
• Low noise level
• The maximum temperature of the transported medium is 120 ° C

EC technology is an intelligent technology that uses an integrated electronic control system to make sure that the engine always works with the optimum load. Compared to AC motors, energy efficiency in EC motors is much higher.

Another feature of energy-efficient motors is their energy-saving potential, not only at full, but especially at partial load. In such operating modes, the efficiency losses are much less than for asynchronous motors of similar power. Lower energy consumption ensures lower operating costs.

Recommendations for application: KBR fans are designed for exhaust ventilation with high temperatures of the transported medium (up to 120 ° C), for example, for kitchens of restaurants, etc., for removing gases during welding, for ventilation of industrial baking ovens, ets.

Design: The case is made of two sheets of galvanized sheet steel and insulated with a layer of mineral wool 50 mm thick. The KBR-EC fans have a folding door for ease of inspection and maintenance. The direction of opening the door can be changed from left to right. The fan is insulated from the housing by means of connectors, vibration dampers are built into the carrier frame.

Motor: KBR fans are equipped with high-efficient EC motors, with impeller with backward curved blades made of galvanized steel. Power electronics is built into the motor housing. All models have one potential-free terminal for service messages. All motors can be used at a frequency of 50/60 Hz. The input signal for single-phase motors can be 200-270 V, for three-phase motors - 380 and 480 V. Speed regulation is carried out using a 0-10 V signal. Each motor has a 10 ... 20 V output for connecting an external potentiometer or sensor.

Mounting: KBR are mounted on a load-bearing frame with vibration dampers, wall mounting is carried out using WBK brackets (optional accessory), external mounting is possible with the installation of a protective cover WSD (optional accessory).
