Solution No 13

By means of a series circuit of multiple buffer tanks, the storage volume can be further increased.

System solution for large facilities with high pressure and temperature level.

Increase in efficiency: ~4.7%


Storatherm Heat
Variomat Giga
Compact manifold
Refix / Reflex
Exvoid Steel / Exdirt Steel
Exvoid T (Solar) / Exdirt
Fillset Compact

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


Variomat Giga

  • The vessels must be connected flexibly. Factory connections are provided. Piping between hydraulic units and vessels, however, is done by the customer.

Expansion line

  • Up to 10 m expansion line in the dimension of the pressure mainte- nance ́s flanges.
  • More than 10 m enlargement of the cross section in line with the ensuing pressure losses


  • 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 of 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 interruption of operation. No provision of filter elements required.
