Przepływowe podgrzewacze wody zwymiennikiem ciepła
Instantaneous water heaters provide hot water instantaneously and only as it is needed. Danfoss offers a comprehensive range of products with different control solutions based on principles of flow, thermostatic, flow and thermostatic or electronic controlling. When you turn on a hot water tap in your home, cold water travels through a pipe into a heat exchanger in the unit. The cold water is heated in the heat exchanger via district heating water or another waterborne heat source. As a result, the water heaters deliver a constant supply of instant hot water.

Akva Vita II
The Akva Vita II is an instantaneous waterheater featuring high performance andsimple operation. It is especially suitable forsingle-family houses and for systems with asimilar domestic hot water requirement.The Akva Vita II can be used directly on dis-trict heating networks with a differentialpressure of max. 2.5 bar.
EvoFlat 4.0W
Węzeł Danfoss EvoFlat 4.0 jest szczególnie odpowiedni do budynków wielorodzinnych z centralnym ogrzewaniem lub siecią ciepłowniczą. To innowacyjne urządzenie wyznacza nowe standardy. Składa się z bloków funkcjonalnych wykonanych ze specjalnie wzmocnionego kompozytu PPS. Dzięki temu węzeł jest niezwykle lekki i ogranicza emisję ciepła do wnętrza. Gładka powierzchnia zmniejsza ryzyko osadzania się kamienia i zatykania.
Wszystkie komponenty są montowane za pomocą nowo zaprojektowanych połączeń zatrzaskowych. W porównaniu z konwencjonalnymi podstacjami z rurami i połączeniami śrubowymi, ta nowa technologia połączeń nie wymaga dokręcania podczas instalacji i uruchomienia.
Strona pierwotna (DH)
Węzeł mieszkaniowy jest wyposażony w dwa regulatory różnicy ciśnień i filtr centralny. Letni bypass utrzymuje ciepło przewodu zasilającego podczas postoju. Zapewnia to szybką reakcję w zakresie ciepłej wody użytkowej w okresie letnim. Bypass jest sterowany termostatycznie.
Ciepła woda użytkowa (CWU)
Dostępne są cztery rozmiary wymienników ciepła, aby zaspokoić wszystkie potrzeby od 37 kW do 70 kW. Evoflat 4.0 M jest wyposażony w inteligentny sterownik, który reguluje przepływ po stronie zasilania w oparciu o temperaturę ciepłej wody użytkowej i objętość pobieranej wody. Stacja posiada zintegrowany regulator różnicy ciśnień po stronie zasilania systemu podgrzewania ciepłej wody użytkowej. Eliminuje to konieczność hydraulicznego równoważenia stacji. W razie potrzeby stację można rozbudować o zestaw cyrkulacji ciepłej wody użytkowej.
Termix BV E
Application
The Termix BV substation is an instantaneous water heater featuring superb heat extraction and high performance. The substation is delivered with thermostatic or automatic controls. The Termix BV is suitable for large apartment houses, sports arenas and schools, where large amounts of hot water are needed. The hot water systems are available in 7 different sizes with an output from 77-222 kW. The Termix BV unit is supplied with PU insulated heat exchangers.
Domestic hot water (DHW)
The domestic hot water is prepared in a plate heat exchanger and the temperature is regulated with thermostatic or automatic controls. The thermostatic solution is regulated with self-acting thermostatic control valves. The substations with high output are controlled with two valves connected in cascade in order to control both small and large demands for hot water in an efficient manner. The Termix BV can also be mounted with automatic controls. There is no additional pressure loss on the secondary side of the heat exchanger with a thermostatic or automatic control valve. Therefore this type of regulation can be used by low pressure in the cold water mains.
District heating (DH)
The district heating circuit is prefabricated with a flow controller with integrated control valve as well as thermometers and ball valves.
Heating (HE)
The heating circuit consists of a plate heat exchanger, safety valve, manometer, thermometers, ball valves, drain valve, air valve and circulation pump. The heating circuit is controlled with an electronic controller with an outdoor temperature sensor.
Options
Termix VVX Compact 28 can be delivered with white-lacquered steel cover and filling line between primary and secondary side.
Termix Novi
Applications
The Termix Novi is an instantaneous water heater featuring superb heat extraction and high performance. The Termix Novi is suitable for flats, single-family houses as well as for small apartment buildings. The water heater is available in two sizes, either for 1 apartment, or up to 4 apartments. The Termix Novi is applicable for decentralized heating systems – as well as for district heating networks with summer operation at low temperatures or with changes in differential pressure. The heat exchanger in Termix Novi cools the district heating water very efficiently, thereby creating a very good operation economy.
Domestic hot water (DHW)
The domestic hot water is prepared in the heat exchanger and the temperature is regulated by a flow-compensated temperature controller with a integrated differential pressure controller. The Danfoss IHPT valve ensures a stable hot water temperature by varying differential pressure without the need for readjusting the valve. This protects the heat exchanger against overheating and lime scale formation. Furthermore the IHPT valve has an integrated idle temperature controller, which keeps the house supply line warm. This shortens the waiting periods during summer when the heating system is in reduced operation, which is ideal where high comfort is requested.
Options
The water heater can be supplied with a built in non-return valve and safety valve mounted in the cold water supply. The water heater can also be supplied with a thermostatic circulation valve and a non-return and pressure equalizer (GTU).
Termix One-B
Application
The Termix One is an instantaneous water heater featuring superb heat extraction and high performance. The Termix One is suitable for flats, single-family houses as well as for small apartment buildings with up to 10 apartments. The water heater is available in three sizes, either for 1 apartment, for 1-4 apartments or for 5 up to 10 apartments. The Termix One is applicable for decentralized heating systems – as well as for district heating networks with summer operation at low temperatures or changes in differential pressure. The Termix One heat exchanger cools out the district heating water very efficiently, thereby creating a very good operation economy.
Domestic hot water(DHW)
The domestic hot water is prepared in the heat exchanger and the temperature is regulated with a thermostatic control valve. The patented sensor accelerator accelerates the closing of the Danfoss AVTB valve and protects the heat exchanger against overheating and lime scale formation. The sensor accelerator and AVTB valve also works as a bypass keeping the house supply line warm. This shortens the waiting periods during summer when the heating system is in reduced operation. The sensor accelerator helps to ensure a stable hot water temperature by varying loads, flow temperatures and differential pressure without the need for readjusting the valve. There is no additional pressure loss on the secondary side of the DHW heat exchanger with a thermostatic control. Therefore this type of regulation can be used by low pressure on the in the cold water mains.
Options
The water heater can be supplied with built in non-return valve and safety valve mounted in the cold water supply. The water heater can also be supplied with a thermostatic circulation valve and a non-return and pressure equalizer (GTU).
