Akva Lux II VXi, w/o controller

District heating substation for indirect heating and instantaneous domestic hot water. Innovative DHW temperature control, PTC2+P with energy-saving function. For wall-mounting with pipes connection in top or bottom.

Application
The Akva Lux II VXi is a fully insulated substation featuring high performance and simple operation.The Akva Lux II VXi is especially suitable for two pipe systems and systems with floor heating.The substation is available in several capacity variants.
​​​​​​​
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.
​​​​​​​
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
The substation is equipped with 3/4” fitting pieces for fitting of a heat meter in the DH return flow.
​​​​​​​
Service and maintenance
The substation is very service friendly and easy to install.It is mounted on the wall and as all pipes are placed in pipe bracket distance, it is possible to establish a nice piping either in the top or in the bottom of the substation.The white removable center part in the front insulation allows easy access to components for regulation and maintenance purposes.
