B35-9 is a compact DOUBLE TUBE solar station, completely premounted to be installed in solar circuit and capable of covering surfaces up to 70 m² of flat collectors or 50 m² of evacuated collectors. The station is equipped in the return section with a flow meter with a regulation range of 5-35 l/min, a drain tap, a Wilo Yonos Para 15/1-9 PWM2 highefficiency exchanger, a safety unit consisting of a pressure gauge (0-10 bar), safety valve set at 6 bars, a filling tap, and couplings for connecting the solar expansion vessel; finally, a blue ball valve with a check valve (20 mbar) and an integrated thermometer close the return section. In the outlet section there is a red ball valve equipped with a thermometer and integrated check valve and large degasser designed to eliminate air during the system startup phase as well as ensure correct operation of the system over time.
Connecting two B35-9 in parallel can guarantee coverage of solar systems up to 140 m² of flat collectors or 100 m² of evacuated collectors.
