The solar thermal kit Sonnenkraft COMPACT AND SKR500 are constituted by a series of places solar collectors on the roof, capable of absorbing the radiation from the sun to heat the heat transfer fluid.
The heat transfer fluid is transferred from the collectors to the kettle DHWPR2 by means of a circulator in this solar pump group, managed by a control unit, which detects when the temperature in solar collectors is higher than that present in the kettle.
The kettle DHWPR2, place inside the building, stores the hot water to be used by the user when needed. The components in the system are:
- Collector SKR500 vertical flat type frameless, for overhead installation with 2.57 square meters gross area, hydraulic circuitry meander with 4 water connections plug-in, hot molded from corrosion-resistant aluminum die. The fixtures available can install SKR500 collectors on a flat roof or a pitched roof, thereby covering all types of cases.
- DHWPR2 kettle double coil, enamelled according to DIN4753 part 1 to manage a maximum temperature up to 95 ° C (ErP class C).
- Solar pump unit RLGHE complete with control unit, pre-assembled on board the DHWPR2 kettle. Group solar pump provided with high efficiency circulator that reduces power consumption by up to 80%, compared to a conventional circulator.
- Solar expansion tank, antifreeze to be mixed, health thermostatic mixing valve.
