Solution No 10

Heating facilities with higher water volume and higher level of pressure.

Pump-controlled dynamic pressure maintenance and simultaneous degassing with the Reflex Variomat.

Increase in efficiency: ~4.7%


Storatherm Heat
Refix / Reflex
Exvoid Steel / Exdirt Steel
Exvoid T (Solar) / Exdirt
Sinus EasyFixx
Fillset Compact

This chart is merely for illustrating the different connections. It has to be adapted to local conditions and fleshed out.



  • Used as dirt and sludge separators no clogging occurs as with conventional filter systems; thus consistently low resistances and pressure losses during operation with constant separation quality.
  • Dirt and sludge removal efficiency up to 5 μm.
  • No specified flow direction
  • Optional: high-performance magnetic insert for ideal separation of ferromagnetic particles, such as magnetite.
  • All Exdirt separators are maintenance-friendly and can be cleaned without interrupting operation. No provision of filter elements required.

Control Vessel

  • The expansion vessel for individual protection of the boiler also serves as a control vessel.

Connection of pressure maintenance

  • Simple and error-free connection of pressure maintenance or degassing using Sinus EasyFixx allows convenient and easy installation of Servitec. At the same time, the connection is directly on the manifold and hydraulically integrated into the pressure raising system.
