Akva Lux II VXe HT

Applications
Akva Lux II VXe HT is a fully insulated district heating substation for indirect heating and instantaneous domestic hot water, featuring high performance and simple operation. The Akva Lux II VXe HT covers both the DHW and heating requirements of large and small single-family houses and is also suitable for large projects. The Akva Lux II VXe HT can be used in high or low temperature district heating networks (T_max= 130°C).

Construction
The Akva Lux II VXe HT substation is available in two main types with a plate heat exchanger for domestic hot water production type XB 06H-1 26 for 1-2 dwellings and heat exchanger type XB 06H-1 40 for 3-4 dwellings. On the heating side the substation is available with heat exchanger type XB 06H-26, 40 and type XB 06L-1 24 for floor heating. The substation also features safety and nonreturn valve on the cold water connection, ball valves and sensor pockets as well as a differential pressure controller, expansion vessel, energy-efficient circulation pump, control valves with actuators, strainers, and a removable fitting piece for installation of heat meter in the district heating return line. Primary pipes of Akva Lux II VXe HT are welded. The heating temperature is controlled by an electronic ECL 310 controller with weather compensation, which enables further energy savings. The substation is suitable and ready for connecting re-circulation.
