Tender specification
EC centrifugal fan modules – RadiPac with high static pressure
sizes 355 to 630
Direct-drive single inlet centrifugal fans with backwards-curved high-performance centrifugal impellers withradial diffusers, mounted on a GreenTech EC external rotor motor with integrated control electronics.
Impeller made of aluminum, with backwards-curved, continuously welded, blades; flow-optimized inlet ring made ofgalvanized sheet steel with pressure test nipple.
Motor impeller statically and dynamically balanced on two planes to balancing grade G 6.3 (motor size 200 tobalancing grade G 4.0) in accordance with DIN ISO 1940.
GreenTech EC external rotor motors achieve or exceed the efficiency specifications in accordance with efficiency
class IE5 (IEC TS 60034-30-2:2016), 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,respectively 3~380-480 V, 50/60 Hz. Fan can be used with all standard power
supply networks with unaltered air performance. Integrated electronics, low-noise commutation logic; 100 % openloop speed control; all fans have an RS485/MODBUS RTU interface, and do not need to be installed with shieldedcables.
Terminal box made of aluminum with easily accessible connection area, environment-resistant cable glands.
Version for wall mounting:Support bracket, sizes 355 and 400 with size 150 motor as ready-to-install support bracket intended for wallmounting. Support bracket made of bent round bar steel or round tube, welded and coated in black. Mounting plateand inlet ring made of sendzimir galvanized sheet steel.
Version for floor mounting:Cube design, sizes 560 and 630 with size 200 motor as ready-to-install cube design intended exclusively for floor
mounting. Struts made of extruded aluminum sections connected to die-cast corner plates, nozzle plate and inlet ring
made of sendzimir galvanized sheet steel, motor mounting plate made of coated sheet steel. This version is notsuitable for wall mounting.
Any work required for isolation from structure-borne noise to be performed by the customer. Fan satisfies theapplicable EMC guidelines and requirements with regard to circuit feedback (for specific information, see therespective data sheet). Documentation and marking conform to the applicable EU Directives.
Reliable performance data, air performance measurements on intake-side chamber test rig according to ISO 5801
and DIN 24163, noise measurements in anechoic rooms according to DIN EN ISO 3745.
Integrated protective devices:- Alarm relay with zero-potential change-over contacts (250 V AC, 2 A, cos φ = 1)
- Locked-rotor protection- Phase failure detection- Soft start of motors- Mains under-voltage detection- Thermal overload protection for electronics and motor- Short circuit protection
