Thermosyphon systems

Termosyphon systems are primarily utilised in the Mediterranean region and are available in two technical setups:

- with integrated condenser in buffer storage
- with a separate collector and buffer storage

With NARVA heat pipe vacuum tubes the system is intrinsically safe. The limitation of temperature  via special evaporator fluid prevents vapour shocks when drawing from the outlets.

Environmental influences such as wind or low ambient temperatures have no influence on the yield of the vacuum tube collectors. Electronic controls and pumps are not necessary, this makes the system less prone to breakdown and require less maintenance.

Collectors with NARVA heat pipe vacuum tubes have a significantly higher degree of efficiency compared to flat plate collectors. In combination with the temperature limitation they are ideally suited for the use in siphon systems.
