Akva Lux II VXe HT (A266)
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 (Tmax= 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.
Heat exchanger for DHW heating
The substation is based on a brazed, highly efficient plate heat exchanger, which is controlled by a VM2 control valve with AMV 33 actuator.
Domestic hot water recirculation
The substation is prepared for connection to systems with DHW recirculation.
Mounting of heat meter
The substation is equipped with ¾” fitting pieces in the DH return flow for fitting of a heat meter.
DSA2 HOME
The DSA HOME is designed for use in high-parameter district heating networks. Suitable for heating single houses. It provides an alternative solution to an oil or gas boiler. The DSA Home is designed for heating or heating and domestic hot water. The wall-mounted construction saves space needed for installation and servicing.
DSA2 WALL
The DSA WALL is designed for use in high-parameter district heating networks. Suitable for heating single and multifamily houses and commercial and industrial buildings. It provides an alternative solution to an oil or gas boiler. The DSA WALL is designed for heating, domestic hot water and floor heating. The wall-mounted construction saves space needed for installation and servicing.
EvoFlat VX-F FH
The VX-F is a compact flat station distinguished by high performance and ease of operation. The EvoFlat VX-F station is particularly suitable for two-pipe systems with underfloor heating supplied by a central heat generator in multi-family buildings. The VX-F FH stations can be used either independently or in combination with a VX-F heating circuit manifold with 2 to 12 heating circuits.
Primary side
The station is supplied with heating water from a heat source. The Flat station is factory‑equipped with a domestic hot water thermostat, differential pressure controller, strainer, summer bypass (FJVR), M10 sensor holder, and a fitting for the installation of a heat meter.
Secondary side
The secondary side consists of a plate heat exchanger, safety valve, pressure gauge, expansion vessel, and circulation pump.
To regulate the supply temperature to the secondary side, a temperature controller of type FTC is used. The EvoFlat VX-F FH is equipped with a safety temperature limiter (55 °C) and a RA‑C zone valve with a TWA thermal actuator, which prevents further heat supply in the event of overheating.
Domestic Hot Water (DHW)
Domestic water heating is carried out using a heat exchanger in a flow‑through principle. The domestic water temperature is regulated by the automatic controller type TPC‑M. This combination controller offers exceptional user convenience by functioning as both a hydraulic and a thermostatic valve.
The flow‑controlled section allows primary and secondary side flow through the heat exchanger only during domestic hot water draw‑off. Immediately after the draw‑off ends, the flow is shut off. The thermostatic section, on the other hand, regulates the domestic hot water temperature. The TPC‑M controller ensures a constant domestic hot water temperature even in the presence of fluctuating supply temperatures and differential pressures.EvoFlat VX-F R
The VX-F is a compact flat station distinguished by high performance and ease of operation. The EvoFlat VX-F station is particularly suitable for two-pipe systems with radiator heating supplied by a central heat generator in multi-family buildings.
The VX-F R stations are for connecting radiators.
