50 Hz
CENTRIFUGAL IN SOUNDPROOF CABINET (DOUBLE)
MANUFACTURING FEATURES
• Impellers made of reinforced polyamide with fiber glass up to size 12/12 (33/33). Size 15/15 made of galvanized steel sheet.
• BD range fans assembled in soundproof cabinets with thermo-acoustic insulation, Bs1d0 fire class on the supply panel.
• Fan assembled on antivibration mountings.
• Connection gland included.
• Equipped with inlet deflector wing, minimizing the turbulence and optimizing efficiency.
• Closed motors specially designed by Casals. Extruded aluminium motor housing. Terminal box on the motor IP 65 protection and motor with IP54 protection and Class F insulation. Standard voltages 230V 50Hz for single phase and 230/400V 50Hz for three phase motors.
• Fans can run separately or simultaneously.
• Fans can run separately or simultaneously.
APPLICATIONS
Designed for inline installation, indoor or outdoor assembly, they are suitable for:
• Air renewal in buildings and industries.
• Industrial and professional kitchen hood. Use in supply or extraction with prior fat filtering.
• Maximum working temperature: 50ºC.
UNDER REQUEST
• 3 speed fans.
• LG0 position.
• Impeller made of galvanized sheet.
• Aluminium box up to size 12/12.
* All data are referred to a single working fan. If both fans are working at the same time, data should be twice (x2) except for weight.

MANUFACTURING FEATURES
• Safety start-stop switches according to IEC 60947-1 and IEC 60947-3.
• IP65 and always equipped an auxiliary contact.
• Useful for switching off the current before handling the fan.
*Máx. thermal current air (A)
MANUFACTURING FRATURES
• Frame made of galvanised sheet and shutters made of aluminium.
• To be fitted on centrifugal fans likeBVFC F400, BOX BD and BOX BV.
• Certified 400ºC/2h.
MANUFACTURING FEATURES
• Outdoor flange with bird guard.
• Made of galvanized Steel.
• VIS OUT = Outlet
• VIS IN = Inlet
WORKING FEATURES
• Electronic system designed and developed for automatic control of Twin-fans, like TWIN BOX BD and TWIN BOX BV.
• The REG TWIN control can be fitted within the Twin-fan housing or at any desired location of operation within the same building. The MODBUS communication protocol is integrated in the REG TWIN control.
• When REG TWIN is set to operate in AUTO mode, each fan will be running for a preset period of time interval (12 hours). In case of failure of any of the fan, REG TWIN automatically starts the Stand-By fan, simultaneously gives signal to the user about the faulty fan.
• An other function of REG TWIN is BOTH FANS RUNNING mode, to run both fans consequently to supply twice the normal air volume.
• Only suitable for single phase and electric motors (EEC).
CHARACTERISTICS
• Power supply: from 80 to 250 V. a.c. or d.c.
• Relay contacts current: 3 A 250 V. a.c. (For external intensities and three-phase motors an external contactor is necessary)
• Working temperature: from 0°C to 50°C.
• Storage temperature: from -25°C to 85°C.
• Relative humidity: max. 95% without condensation
• Dimensions: 104 x 93 x 25 mm.
CONNECTION OPTIONS
• Inside the unit (not connected).
• Attached outside the unit (the IP must be taken into account).
• Remote.
APPLICATIONS
This kind of control can be used to commutate a couple of motors to work in auto change over mode or simultaneously.
In case of TWIN BOX BD, a common application is in high temperatures environments (in the desert for example) where fans run in change over mode to avoid fan overheating problems.
MANUFACTURING FEATURES
• Specially designed for speed frequency control in ventilation applications.
• Ultra compact, simple operation and wide range of functions.
*Dial panel incorporated. Optional EMC filter.
Certifications: CE/UL/CSA/EN/GOST/CCC.
Protection index IP20.
The selection of SFC frequency drive speed controller must be made based on the maximum intensity absorbed by the fan to be regulated. The powers (kW) and the intensity for constant load refer to the normal duty (150% overload for 60 seconds). The intensity for quadratic load admits an overload of 110% during 60s.
SFC 230: Entrance 230V I, exit 230V III
SFC 400: Entrance 400V III, exit 400V III
EMC filter incorporated for models from 47A (included)
