Tender specifications forEC centrifugal fans – RadiCal in scroll housing
EC centrifugal fans – RadiCal in scroll housing
sizes 133 to 225Direct-drive, single inlet centrifugal fans with backward-curved one-piece impellers made of high-techcomposite material, based on a GreenTech EC external rotor motor with integrated control electronics,
installed into a scroll housing.
One-piece, jointless impeller, sizes 133 to 225 mm, with 7 blades made of high-tech composite material. This permits
high circumferential speeds and thus a high power density suitable for a wide range of applications.
Motor impeller statically and dynamically balanced on two planes to balancing grade G 6.3 in accordance with DIN
ISO 21940.
GreenTech EC external rotor motor surpasses efficiency class IE4, magnets with no rare earths, maintenance-freeball bearings with long-term lubrication, theoretical nominal service life of at least 40,000 hours of operation.
Soft start, integrated power limiter, extended voltage input 1~200-240 V, 50/60 Hz. The fan can be used with allstandard power supply networks with unaltered air performance.
Integrated control electronics, low-noise commutation logic; 100 % open-loop speed control via 0-10V/PWM orRS485/MODBUS-RTU interface for standard fans or RS485/MODBUS-RTU interface for versions with constantvolume control (0-10V/PWM optionally possible), shielded lines are not necessary for the connections.
Version with housing construction:Sizes 133 to 225, designed as ready-to-install housing construction. Construction is made of high-tech composite
material, fastening options for installation available. Flexible installation position (please note protection class).
The fan satisfies the applicable EMC guidelines and requirements with regard to harmonic effects (see applicabledata sheet for specific figures).
Documentation and marking in accordance with the applicable EU directives.
Reliable performance data, air performance measurements taken on an intake-side chamber test rig in accordancewith ISO 5801 and DIN 24163. Sound measurements taken in a hemi-anechoic room in accordance with DIN EN
ISO 3745.
Integrated protective devices:-Power limiter
Motor current limitation
Soft start
Overvoltage detection
Thermal overload protection for electronics/motor
Undervoltage detection

Optional:-Other and specific requirements on request
for versions with constant volume control, in addition:
Constant volume can be regulated
Integrated RH/T sensor
Connection options for external sensors

Tender specifications forEC centrifugal fans – RadiCal in scroll housing- FlowGrid air inlet grill
FlowGrid air inlet grill tailor-made for the fan, to reduce assembly and system-related noise. Grill made of highgrade composite material in one piece, available ready for installation and also suitable for retrofitting. Ideal
solution for confined intake conditions at the fan and/or if upstream turbulence-inducing fittings are unavoidable.
The FlowGrid breaks up the turbulence fields and straightens the flow, resulting in distinct noise reduction.
