Blauberg Box-I EC
Supply and exhaust ventilation systems installed in various premises.For arranging energy-saving and controllable ventilation systems.Compatible with 600x300 up to 1000x500 mm rectangular air ducts.
The casing and impeller are made of galvanized steel.The casing is heat- and sound-insulated with 50 mm mineral wool.The fan is rated for continuous operation always connected to power mains.The fan casing has threaded openings for connection of rectangular air ducts.The access cover on the fan casing facilitates servicing and maintenance.
Mounting angles with rubber anti vibration mounts for easy fan mounting.
For connection to rectangular air ducts. The fan flanges are connected to the air duct by the bolts inserted into the flange holes. In case of the fan connection to the air duct via flexible connectors the fan must be secured to a mounting frame with supports, hangers or brackets. While mounting provide enough space for accessing the cover for service operations.
High-efficient direct current EC motor with external rotor and backward curved blades.
EC technologies meet the latest requirements to arrange highefficient energy saving ventilation. EC motors have energy demand by 50 % less as compared to standard motors and have efficiency up to 90 %. EC motors are featured with high performance, low noise level and well controllable total speed range. Dynamically balanced turbine.
OPERATION AND SPEED CONTROL
The fan is controlled with a 0-10 V external control signal, e.g. CDT E/0-10 speed controller for EC motors. The fan capacity is regulated by various parameters, including temperature level, pressure, smoke, etc. EC motor changes its rotation speed synchronously with fluctuations of a control parameter to ensure the best suitable air flow.The fan is compatible both with 50 and 60 Hz power mains with no influence to the motor maximum speed. The parameters may be set and controlled due to data exchange between a PC and the fan. The fans can be integrated into a unified decentralized computerized network to adjust ventilation system with respect to specific user's demands.
