VTS Ventus VVS180 [21/55] Components
COMPONENTS
Design and application
» Centrifugal fan, without casing, single
inlet, PLUG type, with backward
curved blades.
» Impeller made of SAN (styrene/
acrylonitryle) construction material
with 20% glass ber.
» Direct drive – fan impeller installed
directly on motor shaft.
» Fan section consisting of single
or multiple fans (fan array) in
order to ensure optimum working
parameters.
Specication
» Low and medium pressure
ventilation systems with fan static
pressure not exceeding
2000 Pascals.
» Maximum fan set working
temperature: 60°C.
DIRECT DRIVE PLUG FAN SET
» Fan and motor mounted on common
housing, separated from AHU casing
by set of rubber vibration absorbing
mounts.
» Motors of TEFC type
(Totally Enclosed, Fan-Cooled).
» Motors tted for IEC standard.
» Variable Frequency Drive (VFD) –
standard equipment of the fan-set.
» Available Energy classes: IE2, IE3
» Rated voltage: 3x230V AC,
3x400V AC.
» Number of poles: 2 or 4.
» Motor winding insulation class: F
(tted for VFD operations).
» Bearings lifetime: L

= 20000h
/ L
50
= 100000h.
» Protection degree: IP55.
» Maximum working ambient
temperature: 60°C.
> AC MOTORS
» Set of fan and motor mounted on
common rail, xed to the AHU fan
diaphragm.
» EC motors are Permanent Magnet
motor, characterised by much higher
efciency vs traditional inductive AC
motors.
» EC motors (Electronically
Commutated) – where mechanical
commutator switching the windings
has been replaced with electronic
one.
» Change of revolutions is done by
means of changing the frequency
rate of windings switching (rate or
magnetic eld rotating).
» Highly inductive permanent magnets
have applied in EC motors used by
VTS, which enabled to achieve high
torque at relatively small dimensions,
together with reaching IE4 efciency
class.
» Available Energy classes: IE4.
» Rated voltage: EC motors of nominal
capacity exceeding 0,75kW -
3x400V AC.
» Rated voltage: EC motors of nominal
capacity equal or less 0,75kW -
1x230V AC.
» Motor widing insulation class: F.
» Protection degree: IP54.
» Maximum working ambient
temperature: 55°C.
» Lifespan:
- 70 000 hours at load not exceeding
70% of nominal capacity at ambient
temperature not exceeding 35°C,
- 30 000 hours at 100% capacity
load at ambient temperature not
exceeding 55°C.
> EC MOTORS
Design and application
