Solar heat transfer system Solex HF

Upgrade your hydronic heating system with solar thermal!

The compact and completely preassambled solar water heating system Solex for high flow systems is completely insulated. It is equipped with a generously dimensioned stainless steel flat plate heat exchanger, prewired and preset controller. All those advantages allow for a simple and quick installation as well as secure commissioning. Secondary loop supply

Your advantages:

• All connections ¾" female
  
• With pre-assembled steel wall bracket can be mounted easily onto the wall
  
• Fully assembled with flat sealing union connections
  
• Full port ball valves
  
• Flow check valves inside the solar loop and inside the secondary loop, manual opener, inside
  the solar loop with 400 mm WC, especially for solar systems, secondary with 200 mm WC, prevent any
  gravity circulations
  
• Both loops with large ball valve handles
  easy handling, visible closing position, with integrated full metal thermometer 0-160 °C / 32-320 °F, can be
  pulled off, with thermowell integrated inside the ball valve
  
• With solar circulation pumps by Wilo, three speed
  pre-assembled; aligned to the performance of the water heating system, pumps can be completely isolatad- no
  draining necessary during pump service
  
• Primary and secondary loop with flowmeter
  for easy adjustment of the flow rate
  
• Integrated flushing and filling valves
  three drain valves permit filling and flushing the primary circuit as well as only the heat exchanger. On the secondary side automatic airvent at the highest point of the heat exchanger.

Solar safety assembly
pressure relief valve 6 bar / 87 psi, high-temperature manometer 0-6 bar / 0-90 psi with valve, flat sealing connection for expansion tank secondary side fitted with ¾" pressure relief valve connection

Compact function-optimised design insulation
made of durable elastic EPP; 100% insulation of the fittings – minimized heat loss

Highly effi cient stainless steel heat exchanger
two sizes for small and larger installations, designed for high flow operation. Generously dimensioned, for transmitting high performances high ΔT , completely integrated into the insulation.

Integrated solar controller
completely pre-assembled, preset and prewired, assures quick assembly – only the sensors for the storage tank and for the solar panels have to be connected branched. The preset control system makes commissioning simple and clean.
