Akva Lux II VX
Application
The Akva Lux II VX is a substation featuring high performance and simple operation. It is suitable for large single family houses and small apartment houses. The Akva Lux II VX is especially suitable for two pipe systems and systems with floor heating.
Heat exchanger for DHW heating
The substation is based on a brazed, highly efficient plate heat exchanger, which is controlled by a thermostatic and pressure controlled DHW controller, Danfoss PTC2+P with integrated differential pressure controller and energy saving function, which ensures that the heat exchanger is cold during standby. The substation can in special cases be supplied with a gasketed plate heat exchanger.
Bypass (thermostatic circulation)
The water heater is supplied with a thermostatically controlled bypass, which ensures that hot water is produced immediately, when tapping starts. The bypass temperature is set with due consideration of the best possible DHW comfort and economy. The substation is easily rebuilt for application in systems with DHW recirculation.
Domestic hot water recirculation
The substation is prepared for connection to systems with DHW recirculation. Switching to DHW recirculation is possible from a constructional point of view, requiring only mounting of a separate circulation set (see options). The circulation temperature is set independently of the set DHW temperature.This ensures the best possible DHW comfort, very low standby losses and thus a very good district heating economy.
Mounting of heat meter

Heating (HE)
The heating side features a plate heat exchanger and two heating circuits. The radiator heating circuit consists of a safety valve, non-return valve, manometer, thermometers, strainer, expansion vessel, ball valves, multifunctional control valve, actuator and circulation pump, and the floor heating circuit consists of a non-return valve, thermometers, safety thermostat, strainer, ball valves, threeway valve, actuator and circulation pump. The temperature for the heating circuits is controlled by an electronic temperature controller with an outdoor temperature sensor. Depending on substation’s application, different heat exchangers dimensioned for central or floor heating can be used.
Domestic hot water (DHW)
The domestic hot water is prepared in a heat exchanger based on the flow principle and the temperature is regulated by the selfacting controller with integrated differential pressure controller - the PTC2+P with esave™ function. Supreme ease of operation is obtained via the combined hydraulic and thermostatic regulation of the PTC2+P controller. The pressure-controlled part allows primary and secondary side flow through the heat exchanger, only when hot water is tapped and blocks the flow immediately after completion of the tapping process. The thermostatic part controls the domestic hot water temperature. Thanks to the quickacting hydraulic control of the heat exchanger, it is largely protected from the formation of lime scale and growth of bacteria. The PTC2+P controller with integrated differential pressure controller compensates for variations in supply temperature and varying differential pressure and thereby ensures a constant domestic hot water temperature at all times. A thermostatic bypass enables tapping of hot water without any delay, ensuring the best possible efficiency and economy. The cold water connection includes a combined ball valve/non-return valve and safety valve.
