TacoSol Circ ZR PV EU21 (FV 70 Tacosol EU21)
Pump, regulator and air venting unit in solar heating systems
The TacoSol Circ ZR PV EU21 is a globalradiation-driven solar station. The highefficiency D.C. pump is supplied and controlled directly by the current from a PV panel. As such, the standard supply connection, solar regulator, collector and accumulator sensor are no longer required.
The unit is controlled by a built-in temperature sensor in the pump, which regulates and interrupts the flow rate according to the return temperature.
The excess flow is taken up by the MAG. Once the collector cools down, the unit automatically starts up again.
These components allow independent and efficient operation of the unit.
Hydraulic balancing, flow measurement and venting can be performed directly in the station.
Using the scale, which is pre-calibrated for frost protection, the technician can set and check the exact flow-rate values on-site.
Installation and venting can be carried out by one person working unassisted.
Utility model protection has been granted.
