Solar station FlowCon S2F

USE in closed loop design only. The circulation unit is used on the primary circuit of solar heating systems to control the temperature in the hot water storage. Module with two pumps, suitable for two solar storages. The pumps inside the unit are activated by the signal from the differential temperature regulator. In addition, this unit contains the functional and safety devices for optimum circuit control.

Your advantages:

• All medium-bearing parts are made of brass
• All connections ¾" female
• With pre-assembled steel wall bracket,
• Full port ball valve in return pipe
• Check valve inside the supply and return ball valve,
  manual opener, 3 x 200 mm WC each, special design for solar systems, avoid any gravity circulation. The check valves are integrated into the ball valves so that each line has a total pressure drop of 400 mm WC.
• Ball valves are key-actuated
  easy handling, no danger of burnings
• Function-optimised design insulation made of durable elastic EPP;
  100% insulation of the fittings – excellent pump ventilation and cooling
• Application
  In a system with 2 storage tanks, the pumps are connected in order to switch between the storage tanks. This assembly allows a parallel charge of both storage tanks.
• Solar safety assembly
  pressure relief valve 6 bar / 87 psi, high-temperature pressure gauge 0-6 bar / 0-90 psi with shut off valve, drain valves for flushing and filling, flat sealing connection for expansion tank
• Full metal solar thermometer, 0-160 °C, 32-320 °F dual scale
  can be pulled off, with immersion sleeve integrated in the ball valve
• Fully assembled with flat sealing union connections
• With solar circulation pump by Wilo
  pre-assembled, without wire
• Pump can be completely isolated, no draining necessary during servicing
• 2 flowmeters
  Flow quantity measuring devices with adjustable flow quantity gauge and function control device, installed in the (cold) return - up to 130 °C / 266 °F heat resistant – measurement range:
  1 – 13 l/min.
• Flushing and filling unit integrated
  three drain valves (at the flow meter or at the ball valves below the pump and at the safety assembly) permit filling and flushing the system.

The unit components enable:

• Medium circulation with specific pump
  
• Safety against pressure increase
  
• Accurate flow rate control
  
• Filling / draining the circuit
  
• Measuring the supply and return line temperature
  
• Separating the air contained in the circuit
  
• Shutting off the circuits and no return
  
• Thermal insulation
