Akva Vita II TDP-F
Flat station for single-family, semi-detached and terraced houses as well as flats
Application
The Akva Vita II TDP-F is a flat station featuring high performance and simple operation. The Akva Vita II TDP-F is especially suitable for two-pipe systems. The Akva Vita II
TDP-F is developed for flat systems supplied
from a secondary connected district heating
sy-stem, a block heating system or a centrally
located boiler system in a block of flats. The
Akva Vita II TDP-F is available as built-in variant with a recess box or as wall-mounted
variant and is prepared for implementation
with the Danfoss Redan distribution systems
for floor heating or radiator heating.
District heating (DH)
The flat station is prefabricated with interconnecting components such as differential pressure controller, strainer, thermostatic
bypass FJVR, sensor pockets and fitting piece
for insertion of a heat meter.
Heating (HE)
The heating side is designed for direct ge-neration of heat in a two-pipe system. The differential pressure controller sets the optimum
operating conditions for radiator thermostatic valves in order to enable individual temperature control in each room. In order to
enable a time depending temperature
control program the Akva Vita II TDP-F can be
equipped with a zone valve RA-C and electric
actuator TWA-A. A return temperature limiter,
type FJVR, for automatic regulation of the return
temperature from the radiators or the floor heating system can be mounted (not part of the
delivery).
Domestic hot water (DHW)
The domestic hot water is prepared in the heat
exchanger based on the flow principle. Supreme ease of operation is obtained via the combined hydraulic and thermostatic regulation
of domestic hot water through the self-acting
controller with integrated differential pressure
controller - the PTC2+ P controller, thereby
guaranteeing a constant domestic hot water
temperature at all times.
The use of hydraulic regulation widely prevents
the formation of lime scale and bacteria due to
the fact, that the valve closes immediately after
the tapping is ended. Furthermore the combined control function ensures that variations in
temperature in the district heating network are
reduced. A thermostatic bypass enables tapping of hot water without any delay, – ensuring
the best possible efficiency and economy. For
regi-stration of the cold water consumption
the Akva Vita II TDP-F is equipped with a fitting
piece for mounting of a cold water meter in the
DCW inlet
Domestic hot water circulation
The Akva Vita II TDP-F is equipped with bypass function as a standard, but it is prepared for DHW circulation. Equipment for DHW
circulation is optional and must be ordered
separately.
Construction
All pipes are made of stainless steel.
The connections are made by nuts and
gaskets. The Akva Vita II TDP-F can be deli-vered with white-lacquered steel cover for recess mounting or for wall mounting.
