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 110V 60Hz for single 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
• 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.

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 FEATURES
• Circular outdoor flange with bird guard made of galvanized steel.
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.
