Blauberg EC Zentri-PAC Backward Curved Plug Fan with Casing

Responding to the popular demand and customer feedback we have created a special series of centrifugal fans which feature backward-curved blades and benefit from improved impeller design and reliable high-performance EC motors.

The new series includes the most popular fan models, which comply with all modern aerodynamic and energy efficiency requirements with the impeller diameter ranging from 133 mm to 250 mm. The impeller is made of a composite high-tech plastic material with fibreglass reinforcement elements for higher rigidity and stress resistance.

Specially profiled blades are the result of extensive CAD design and long hours of wind tunnel testing help reduce airflow losses and improve the aerodynamic characteristics of fans. Smooth and uniform airflow spread reduces operating noise.

For further improvement of the ease and convenience of fan installation Blauberg Motoren has come up with the latest solution, which enables using Zentri-PAC fans with Plug Fan type casings produced in-house.

ADVANTAGES OF EC MOTORS:

• Efficient performance at any rotation speed of the fan, including very low speed.
• Low heat emission.
• Small overall dimensions of the unit due to external rotor design.
• Maximum fan rotation speed does not depend on frequency in the grid.
• The fan is suitable for connection both to 50 Hz and 60 Hz power mains.
• High efficiency at low rotation speed.
• Energy demand is by 1/3 less as compared to standard motors.
• Data interchange between PC and fan for parameter setting and control.
• Integration of all fans into a unified system and their centralised control.

The electric motor with high-efficient EC motor is a synchronous direct current motor driven by an electronic commutating unit (controller). It has no friction and wearing parts as a collector or brushes, unlike the standard motor. The function of these parts is performed with the maintenance-free electronic circuit of the EC controller.

The EC technology is the state-of-the-art method for arrangement of energy saving and high efficient ventilation.

The energy demand of EC motors is by 50% less as compared to standard motors and efficiency reaches 90%.

These new electric motors are featured with high performance, low noise level and controllable total speed range. The electronic EC-controller enables some other smart functions, e.g. fan control according to measured temperature, pressure and other parameters.

A unique software ensures high control accuracy for fans integrated into a single network. Parameters of a single fan integrated into a common network may be centrally corrected to match the ventilation system parameters. All the system parameters are displayed online on a computer. This enables programming individual operation modes of each fan in the system. This technology enables also programming custommade settings to meet individual customer requirements.
