Reflexomat
Theoretical principles
1) Low temperature
At lowest system temperature, Reflexomat receives the minimum water seal.
2) Temperature increase
The controller immediately responds
and opens the air solenoid valve when the system temperature and, therefore, the pressure rises. The expansion water can now enter the vessel.
3) Full capacity
At maximum system temperature, the Reflexomat contains the entire expansion water and, therefore, the maximum filling level.
4) Cool down
Cools the system; when the system pressure drops, the Reflexomat,
with the help of the compressor, feeds the expansion water back into the system. Maximum pressure fluctuation is just 0.1 bar.

Variomat
Theoretical principles
1) Low temperature
At lowest system temperature, Variomat receives the minimum water seal.
2) Temperature increase
The controller immediately responds and opens the overflow when the system temperature and, therefore, the pressure rises. Expansion water flows into the de-pressurised vessel and is degassed due the drop in pressure.
3) Full capacity
At maximum system temperature, the Variomat contains the entire expansion water and, therefore, the maximum filling level.
4) Cool down
Cools the system; when the system pressure drops, the Variomat, with the help of the compressor, feeds the expansion water back into the system. Maximum pressure fluctuation is just 0.2 bar.
5) Water make-up
The Variomat automatically opens the water make-up valve to offset the water loss when the water level in the vessel drops below the defined target value.
