VTS Ventus VVS650 [42/55] Air damper
Design and application
» Block of copper pipes integrated with
another block of aluminum ns, creating
expanded heat exchange surface. Pipes
are bonded to the collectors, equipped
with headers (for connecting entire coil
to the cooling system circuit).
» Heating of the air supplied to the
handled spaces.
» Re-heating of the air as a part of air
dehumidifying process.
Specication
» Max medium temperature: 60°C.
» Max medium working pressure:
3,84MPa = 38,4bar (test: 50bar).
» Heating capacity: parameter resulting
from individual performance
calculaation of selected unit (CCOL).
» Max. refrigerant working pressure:
3.84 MPa = 38.4 bar (test: 50 bar).
» Thermal power: parameter available
from technical data of the unit (CCOL).
» Pressure loss / medium ow:
parameters available from technical
data (CCOL).
» Heat exchanger suitable for operation
as a cooler (evaporator) and as a heater
(condenser) in a heat pump circuit.
Cooling function
» Cooling of the ventilation air supplied
to the room.
» Dehumidication of the ventilation air
in summer.
» The exchanger is mostly used for
smaller cooling capacities compared
to water coolers and in "single" air-
conditioning systems.
Heating function
» Heating or cooling of ventilation air
supplied to the room.
» Heating of the ventilation air after
a drying process.
» Cooling of the ventilation air supplied
to the room.
» Dehumidication of the ventilation air
in summer.
» The exchanger is mostly used for
smaller cooling capacities compared
to water coolers and in "single"
air-conditioning systems.
DIRECT EXPANSION COIL AS CONDENSER IN HEAT PUMP CIRCUIT
Design and application
» A pack of copper tubes integrated
with a pack of ns forming the heat
exchange surface extension.
The heat exchanger tubes are
connected respectively to collectors,
to which the connection pipes of the
medium system are routed.
» The exchanger connecting pipes
are equipped with a drain and a vent
respectively.
Features
» Maximum glycol content 50%.
» Minimum temperature for chilled water
+2°C.
» Maximum heating medium
temperature: 150°C.
» Max. refrigerant working pressure:
1.6 MPa = 16 bar (test: 21 bar).
» Thermal power: parameter available
from technical data of the unit (CCOL).
» Pressure losses on the medium side:
available in technical data generated
in the CCOL selection programme.
» Connecting the exchanger supply in a
parallel ow circuit reduces the heater
power by up to several %.
Cooling function
» Cooling of the ventilation air supplied
to the room.
» Dehumidication of the ventilation air
in summer.
» The exchanger is used in complex
air-conditioning systems - several or
more devices supplied from a single
source of cold (water chiller) or in case
of using a single device with relatively
high cooling power.
Heating function
» Heating of the supply air to the room.
» Heating of the ventilation air after
a drying process.
» The exchanger is used in case
of access to a heating water system
(local boiler room or municipal
network).
WATER COOLER
Design and application
» Block of copper pipes integrated
with another block of aluminum ns,
creating expanded heat exchange
surface. Pipes are bonded to the
collectors, equipped with headers
(for connecting entire coil to the
cooling system circuit).
» DX cooler is also available as heater
execusion (so calleed Condenser).
» Cooling and dehumidifying of
the air as a part of air complex
dehumidifying process in summer
season.
» Coil usually applied for smallerd
cooling capacity systems vs
water coolers or for individual air
conditioning systems.
Specication
» Min. Refrigerant evaporation
temperature: +3°C.
» Max refrigerant working pressure:
2,2MPa=22bar (test: 29 bar).
» Cooling capacity - parameter
resulting from individual performance
calculation of selected unit (CCOL).
DX COOLING COIL
Design and application
» Blades made of aluminium with rubber
gasket on the edges.
» Aluminum frame.
» Blades drive realized by means of gears
made of composite material, installed
on frame internal side.
» Damper is equipped with square pivot,
tted for actuator (dampers of cross
section greater than 4 m
2
have 2 linked
pivots).
Specication
» Air leakage at closted damper:
50m

/h*m
2
- at 100 Pascals of
pressure difference.
» Workint temperature range:
-40 ÷ +70°C.
AIR DAMPER
Design and application
» Flexible connection made of 1
mm thick and 30 mm wide hot-dip
galvanized steel proles and polyester
fabric coated with PVC.
» Flame resistance: UL94 - HB [ISO 1210].
» Flexible connection resistant to UV
radiation
» Working temperature range:
-30°C do +70°C.
» Max connection length
(fully spread position): 110 mm.
» Flexible connection installed on each
AHU/Duct joint eliminates transfer
of possible AHU vibrations to the
ventilation ductwork.
Specication
» Max air face velocity: 5m/s.
» Working conditions: -40 ÷ +70°C.
