TWIN BOX BD PLUS 12/12 T6 1,1kW

DOUBLE CENTRIFUGAL FAN IN SOUNDPROOF CABINET WITH SANDWICH PANELS

MANUFACTURING FEATURES
• Impellers made of polyamide reinforced with fibreglass for models 7/7, 9/9, 10/10 and 12/12, other models made of galvanized steel sheet.
• BD range fans assembled in soundproof cabinets.
• Ventilation box with 30 mm aluminum profile structure, nylon corners, galvanized sandwich panels with internal insulation rockwool (25mm thickness) class A1 (non-combustible) of 90kg/m3 density. All panels are equipped with "fastening system" for the quick assembly and disassembly whenever required, either for cleaning, maintenance or exchanging of panels.
• Cable exit through cable glands.
• Easy access through lateral panel.
• Changeable rear, bottom or top inlet cover.
• Closed motors specially designed by Casals. Extruded aluminium motor housing. Totally enclosed wiring box. IP-55 motor protection and rated class F insulation. Standard voltages 230V 50Hz for single phase and 230/400V 50Hz for three phase motors.

• 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.
• Maximum working temperature: 50ºC.

UNDER REQUEST
• 3 speed fans.
• Impeller made of galvanized sheet.

* 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.

Information
CONTROL AUTO CHANGE OVER PANEL FOR TWIN FANS

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.

FREQUENCY SPEED CONTROLLER

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)
