Fans with EC-motors

Product catalog summary

Introduction to EC Motors:
EC motors are highlighted for their energy efficiency and environmental benefits. They utilize electronic control to maintain optimal load, reducing energy consumption and noise levels. These motors are synchronous, eliminating slippage losses, and are ideal for demand-responsive ventilation systems.

Advantages of EC Motors:

High efficiency across the control range.
Long service life with minimal overheating risk.
Easy control via 0-10V DC or PWM signal.
Low noise levels.
Integrated control and protection electronics.
No power loss or increased noise at startup.

Included Features: Overheat and overload protection, locked rotor protection, control electronics, and soft start functionality.

Comparison with Conventional Technology:
EC motors consume less power annually compared to traditional motors, with a lower CO2 impact based on European electricity production standards.

Product Specifications:
K EC Series: Designed for duct installation with backward-curved blades and external rotor motors. Features include thermal protection, galvanized steel casing, and IP 55 rated terminal box.

KVKE EC Models: Single inlet centrifugal fans with high static pressure and efficiency. Features include thermal protection, easy maintenance, and rockwool insulation.

MUB-EC Fans: Modular system with flexible airflow direction, suitable for various mounting positions. Features include integrated electronics, backward-curved blades, and aluminum casing.

DVC Roof Fans: Driven by EC motors with integrated motor protection. Suitable for speed control and constant pressure operation, with aluminum casing and backward-curved impellers.

Conclusion:
EC motors offer significant energy savings, reduced noise levels, and enhanced control capabilities, making them a superior choice for modern ventilation systems.

2 The products in this leafl et are equipped with EC-motors. EC-technology is intelligent technology, using integral electronic control to ensure that the motor always runs at optimal load. What can EC achieve? EC-fans are favoured for their economical use of energy and simplifi cation of control. EC-fans are driven by energy-saving motors with electronic control (commutation unit) to keep them running in the optimal operating range. According to their design principle, these are synchronous motors, which run without slip and therefore no slippage losses occur. An excellent solution for demand...

4 • EC-motors, high effi ciency • 100% speed controllable • Speed regulator included • Integrated motor protection • Supplied with mounting bracket The K EC series is designed for installation in ducts. All the K-fans have minimum 25 mm long spigot connections. The fans have backwardcurved blades and external rotor motors (EC). The FK mounting clamp facilitates easy installation and removal, and prevents the transfer of vibrations to the duct. The fans are delivered with a pre-wired potentiometer (0-10V), set to 10V from factory. This can easily be changed if the installation requires a lower...

6 • EC-motors, high effi ciency • 100% speed controllable • Speed regulator included • Low noise level • Integrated motor protection The KVKE EC models have a single inlet centrifugal fan with backward- curved blades and a maintenance-free external rotor motor (EC). These fans develop relatively high static pressure and have a very high effi ciency. The fans are delivered with a pre-wired potentiometer (0- 10V). The potentiometer is set to 10V from factory. This can easily be changed if the installation requires a lower duty. The KVKE motor and impeller are mounted on the access cover for easy...
