Tender specification
EC centrifugal fan modules – RadiPac with increased corrosion protection
Fan sizes 250 to 1000
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 5 backwards-curved, continuously welded, hollow-profile blades; impeller sizes 250
and 280 made of plastic; flow-optimized inlet ring made of galvanized sheet steel with pressure test nipple; paintedblack.
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 theefficiency specifications in accordance with efficiency class IE5 (IEC TS 60034-30-2:2016), magnets with no rareearths, 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 1~200-277 V, 50/60 Hz 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 % open-loop speed control; all fans have an
RS485/MODBUS RTU interface, and do not need to be installed with shielded cables.
All 1~ types have an integrated active PFC (Power Factor Correction) to reduce disturbing harmonic content.
Terminal box made of aluminum/plastic with easily accessible connection area, environment-resistant cable glands,
or with external variable cable (sizes 250 to 280).
Version for wall mounting:support bracket, sizes 250 to 560 and 630 to 800 with size 150 motor as ready-to-install support bracket intended forwall mounting. Support bracket made of bent round bar steel or round tube, welded and coated in black. Mounting
plate and inlet ring made of sendzimir galvanized sheet steel.
Version for floor mounting:cube design, sizes 630 to 1000 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 the applicable EMC guidelines and requirements with regard to circuit feedback (for specific information,
see the respective 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
