The SECUterm thermosiphon system* was designed specifically for conditions around the Mediterranean, in the sub-tropics and tropics where solar irradiation is high. By using physical principles it needs no external electricity supply, driven only by sunshine. Thermosiphon refers to a method of passive heat exchange based on natural convection which circulates liquid without the necessity of a mechanical pump.
Highest Heat Yield of All Thermosiphon Systems
Our SECUterm 160 / 200 with its powerful solar collector EURO L42 TS and optimized heat insulation marks the performance peak among thermosiphon systems. The Test Center Saarbrücken (TZSB), a branch of the renown Institute for Future Energy Systems (IZES), tested the system along the Solar Keymark rules. Of all actually published Solar Keymark certified installations in its class SECUterm achieved the highest yields (location Athens).
Simple and variable installation
Extensive pre-assembly and detailed instructions facilitate simple racking. The SECUterm system is suited to both free-standing and on-roof installation.
The especially durable hot water tank is delivered together with a high-performance solar collector specifically developed for the system. Innovative thermostatic protection safely prevents the system from overheating.
Best in the South, reliable in the North
SECUterm’s great reliability makes it especially suitable for tropical and sub-tropical regions with high solar irradiation. But it also delivers a reliable yield in the northern hemisphere. SECUterm comes in various sizes to suit households of three to six people. The system can also be combined into larger installations.
