VTS VENTUS N-type NVS 65 DX3.1.V [7/13] Cooling section with a direct expansion cooling coil
![VTS VENTUS N-type NVS 65 PG4 [7/13] Cooling section with a direct expansion cooling coil](/views2/1894818/page7/bg7.png)
COMPOSITION:
Direct driven PLUG fan with a water
coil cooler in insulated casing.
COOLING SECTION
WITH A WATER COOLING COIL
CONSTRUCTION:
The water section consists
of a fan set, a three-row cooling coil
with droplet eliminator and
“monocoque” casing that provides
perfect thermal insulation,
high rigidity and a drainage system
(for condensing water).
WATER COOLER:
Tube diameter: ½”.
Number of R rows: 3.
Minimum ice water temperature: +5°C.
Maximum operating pressure
of the medium: 1.6 MPa = 16 bar (tested
21 bar).
Maximum content of glycol: 50%.
FUNCTIONS AND APPLICATION:
Cooling of the air supplied
to the room.
Air dehumidication.
The combination of a fan set
with a cooler in one block provides the
high tightness and strength of the section.
The construction ensures that the fan and
the cooling coil are perfectly matched.

high rigidity and a drainage system
(for condensing water).
DIRECT EXPANSION
COOLING COIL SECTION:
Copper tubes with embedded
aluminium ns (Cu/Al).
Tube diameter: ½”.
Minimum temperature of the medium
for ice water: +3°C.
Maximum operating pressure
of the medium: 2.2 MPa = 22 bar
(tested 29 bar).
FUNCTIONS AND APPLICATION:
Cooling of the air supplied
to the room.
Air dehumidication.
The combination of a fan set
with a cooler in one block provides
the high tightness and strength
of the section. The construction ensures
that the fan assembly is properly
connected to the cooler.
CONSTRUCTION:
Copper tubes with xed
aluminium lamellas (Cu/Al).
Tube diameter: ½”.
Number of rows: 2.3.
Maximum temperature
of the medium (heat carrier) 150°C
(automatics up to: 140°C).
Maximum operating pressure
of the medium: 1.6 MPa = 16 bar
(test: 21 bar).
Maximum content of glycol: 50%.
FUNCTIONS AND APPLICATION:
Heating of the air supplied
to a room.
Heating of the air after
the dehumidication process.

ELECTRIC HEATER
CONSTRUCTION:
The assembly of the resistance
heating elements made
of Cr-Ni-Fe alloy,
each with 6 KW / 400 V capacity.
As a standard, the heater
is equipped with a thermostat
to protect from overheating.
FUNCTIONS AND APPLICATION:
Heating of the air supplied
to the room.
Heating of the air after
the dehumidication process
in the summer.
Minimum air ow velocity: v = 1.0 m/s.
Maximum allowable ambient
temperature around the heating
elements: 65°C.
Heating elements are connected
in groups, each with a capacity
of 18 kW.
The required heating power can be
obtained through a exible regulation
system or through a gradual adjustment
(wiring diagram available
in the operating manual).
