VTS Ventus VVS650 [23/55] Dx cooling coil

VTS Ventus VVS400 [23/55] Dx cooling coil
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
medium supply system).
» Heating of the air supplied to the
handled spaces.
» Re-heating of the air as a part of air
dehumidifying process.
» The coil can be applied if heating
medium is available (local boiler or
district heating system).
» Coil headers are equipped with
medium damping valve and air vent.
» Connecting the coil in parallel
medium ow vs air, will result in its
capacity reduction by over a dozen
percent.
Specication
» Max glycol concentration: 50%.
» Max medium temperature: 150°C.
» Max medium working pressure:
1,6MPa = 16bar (test: 21bar).
» Heating capacity: parameter resulting
from individual performance
calculaation of selected unit (CCOL).
» Medium side pressure drop –
parameter resulting from individual
performance calculation of selected
unit (CCOL).
WATER HEATER
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).
DIRECT EXPANSION COIL AS CONDENSER IN HEAT PUMP CIRCUIT
Design and application
» Set of resistive heating elements
made of CR-Ni-Fe alloy, 6 kW/400V
each.
» Coils mounted on hot-dip galvanized
steel frame.
» Heater is equipped with power
terminals and thermostat protecting
against overheating.
» In case of AHU with complete
controls, heater is equipped with
integrated capacity control module.
» Heating capacity can be modied by
means of smooth regulation module
(HE module, set of Solid State Relays
as optional parts of AHU controls) or
by means of automatic engaging of
next heating sections.
Specication
» Max permissible ambient
temperature around heating
elements: 65°C.
ELECTRIC HEATER
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
medium supply system).
» Cooling of the air supplied to handled
spaces.
» Cooling and dehumidifying of
the air as a part of air complex
dehumidifying process in summer
season.
» Coil can be applied in complex air
conditioning systems consisting of
few or over a dozen of units supplied
from common chilling source (chiller)
or in case of single unit of relatively
high cooling capacity.
Specication
» Max glyccol concentration: 50%.
» Min supplying medium temperature:
+2°C.
» max medium working pressure:
1,6MPa = 16bar (test: 21bar).
» Cooling capacity: parameter resulting
from individual parameters of
selected unit (CCOL).
» Medium pressure drop / ow rate:
parameter resulting from individual
performance calculation of selected
unit (CCOL).
» For reversed operationg mode
(heating) max medium working
temperature: 140°C.
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).
