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
• Allows duct connection.
• Made of galvanized steel.
MANUFACTURING FEATURES
• Outdoor flange with bird guard.
• Made of galvanized Steel.
• VIS OUT = Outlet
• VIS IN = Inlet
MANUFACTURING FEATURES
• Accessory for connection of BOX BD, BOX BV and BVFC F400 cabinet fans to a circular duct using anti-vibration canvas.
• Fire resistance M0 of -50ºC to 200ºC in continuous and 400ºC/2h.
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)
*Lineal load rated current
**Quadratic load rated current
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
• Support of great radial and axial elasticity.
• These low-profile, compact and elastic supports control the three directions of movement with large deformations in the rubber.
• It consists of two parallel armour adhered to the bell-shaped rubber and by a base with handles.
• These supports with handles have a threaded hole in their upper frame and are easy to install and fix.
• The steel protection washer allows it to withstand overloads by increasing its rigidity and protects the rubber from dripping hydrocarbons.
• Elastomer type NR or high quality elastomer. Working temperatures between -40ºC and + 70º C.
• Taking into account the tolerances of hardness in the elastomers, the mechanical characteristics of these series may differ.
• Range of 6 sizes and 3 different hardnesses (45-60-75) to fit a load range between 2 Kg and 1300 Kg.
1. Soft: hardness A 45
2. Average: hardness B 60
3. Hard: hardness C 75
APPLICATIONS
• Very appropriate in the elastic suspensions of machines that present vibrations of horizontal components.
MANUFACTURING FEATURES
• Metal insulators designed to work with compression with 85% insulation according to the following arrows (travel in mm) and rpm:
Arrow (mm.) r.p.m.
20 mm >600 r.p.m.
30 mm >500 r.p.m.
• Made of high quality elastic steel, with rectangular base and rubber mat to improve the grip. It treats of a resistant product and easy assembly, that avoids all type of vibrations of the fans to the structure of the premises.
• Operating temperature from -45 ° C to + 120 ° C.
APPLICATION
• To install under machines with rotating components, ventilation groups, fans, ventilation boxes, etc.
