Solar station with universal controller
The SOLSTAR solar station is connected to the primary circuit of a solar thermal system and contains all the components which are necessary for optimum operation of the solar thermal system. The ttings are made from EN 12165 CW614N brass. With appropriate water/glycol frost protection (max. 50%), the solar station can be operated in a temperature range from -10°C to 160°C. G3/4" connections throughout should shorten installation times.
Features:
- WILO Solar thermal pump ST20/6
- High quality solar controller
- 2 ball valves with gravity brakes
- Flowmeter
- Flow controller
- Safety valve and pressure gauge
- Bleed device
- Filling and emptying connections
- Connection for expansion tank
