Tender specification for
EC centrifugal fan modules – RadiPac
EC centrifugal fan modules – RadiPac with motor enclosure and hose for food service sector
Fan sizes 400 to 500
Direct-drive, single inlet centrifugal fans with backwards-curved high-performance centrifugal impellers
with radial diffusor, based on a GreenTech EC external rotor motor with integrated control electronics
and a motor enclosure.
Impeller made of aluminum, with 7 backwards-curved, continuously welded blades; flow-optimized inlet ring madeof galvanized sheet steel with pressure test nipple. Motor-impeller in accordance with DIN ISO 21940, staticallyand dynamically balanced on two planes to balancing grade G 6.3.
FlowGrid air-inlet grille, for reducing mounting-related and system-related noise. Ideal solution for confined intake
conditions at the fan and/or if upstream turbulence-inducing fittings are unavoidable. The FlowGrid breaks up theturbulence fields and straightens the flow, resulting in distinct noise reduction.
GreenTech EC external rotor motors achieve or exceed the efficiency specifications in accordance with efficiency
class IE5 (IEC TS 60034-30-2:2016), permanent magnets with no rare earths, maintenance-free ball bearings
with long-term lubrication, theoretical nominal service life of at least 40,000 hours of operation.
Soft start, integrated current limitation, extended voltage input 3~380-480 V, 50/60 Hz. The fan can be used withall standard power supply networks with unaltered air performance.
The motor and control electronics have been removed from the contaminated air flow in accordance with
VDI 2052 and EN 16282. Motor and control system in accordance with EN 60335-1.
Electronics integrated in motor enclosure, low-noise commutation logic; 100 % open-loop speed control; all fanshave an RS485/MODBUS RTU interface and do not need to be installed with shielded cables.
Terminal box made of aluminum integrated into housing, cover made of PA66, with easily accessible connection
area, environment-resistant cable glands. Robust, corrosion-resistant motor enclosure, completely sealed (IP54),
made of CDP-coated sheet steel.
Support structure, ready to install, for wall mounting. Struts made of extruded aluminum profile. Mounting plate
made of galvanized sheet steel. Ready-made intake nozzle for external air supply DN 100. Pre-installed, flexible
air hose between motor capsule and nozzle plate; easily replaceable; good mechanical resistance, flame
retardant in accordance with UL 94 V-0. Easy cleaning and inspection in accordance with EN 16282.
Any work required for isolation from structure-borne noise is to be performed by the customer.
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 in intake-side chamber test rig according to ISO 5801
and DIN 24163, sound measurements in an anechoic test chamber in accordance with DIN EN ISO 3745.
Integrated protective devices:-Alarm relay with floating contacts (250 V AC/2 A, cos φ = 1)
Locked-rotor protection
Phase failure detection
Soft start of motors
Line undervoltage detection
Thermal overload protection for electronics and motor
Short circuit protection
