General Details
Characteristics
- Optimum heat transfer due to plate heat exchanger
- For systems with buffer accumulator and multi-layer charge accumulator
- Buffer accumulator remains maximally cool in the lower area
- Maximal solar outflow temperatures are reached due to the speed-controlled flow rate
- Even in the case of diffuse solar radiation, the maximum solar yield is guaranteed by the speed control and optimal heat transfer via the plate heat exchanger
- Integrated flow transmitter and temperature sensor
- Valve for layer charge
- Filling and flushing device
- Safety fittings
